What is Data Transfer?

What is Data Transfer and why is it so important for your Productivity

Author: Martina Thomas

The term ‘Transfer' in the word Data Transfer refers to the amount of information that is transfer from one system to another. This may refer to the transfer between two computers, a computer and an external storage device or two devices. Many people know the term by do not actually know that data transfer actually means. When you register on another website and enter your information, some of the fields are filled automatically by your computer while the others have to be filled manually by you. This data is then transferred onto the host server when you register.  It also occurs when you download items from the internet such as songs, videos, documents and other items. If you have a web page, you probably know that when a visitor comes on your web site, his or her IP address and location is recorded on your server, or in a 3rd party server. However, at times the speed of the transfer decreases gradually. This may be due to the age of the systems or due to some mechanical or technical problem with the transferring medium. When this happens, it creates a lot of problems for an individual. Imagine that you are a student and you have to prepare a school project at the very last minute. You have completed the project and only have to print the document out. However, your data transfer cable is not working, nor is your USB drive. Or imagine that you are a junior position professional at a company and you are looking for a chance to prove your worth. You finally get the chance and have to print out and deliver a presentation. By the data transfer is too slow and does not work. So you can see, that something as mundane as data transfer can affect our lives largely. When this happens, you have to call in for the help of the professionals.

What is Data Transfer?

Transfer of data takes place by analogue and digital means. In the analogue transmission of data, a continuous stream of analogue signal is transferred from one signal to another. In the digital mode of transfer, data does through a blend of digital and analogue channel, by a line of digital pulses. Problems can take place at any of these processes, making the whole transmission come to a standstill.

In order to make sure that this does not occur, you need to get your data transfer unit tested regularly at a service centre. For best results, you should take the Data Transfer Support services of a company who can give you remote PC support at anytime of the day. This is important because problems can occur at anytime. You also need the services of a company which possesses highly advanced utilities and technologies as these can ensure that you can transfer data at a much faster rate. Thirdly, choose the Operating System Support services of an organization that can give you instant solutions to all of the problems.

What is the Difference Between Download Speed and Upload Speed?

What is the Difference Between Download Speed and Upload Speed?

Author: Emily Hayes

As you shop around for the speediest Internet connection money can buy, you might hear the terms 'download speed' and 'upload speed.'  Sales people are always pointing at those numbers to show the superiority of their particular products.  What do those terms actually mean, and what do the speeds mean to your every day life?

[caption id="attachment_1128" align="aligncenter" width="650"] What is the Difference Between Download Speed and Upload Speed?[/caption]

With a broadband Internet connection, signals are bounced up to satellites and then back to your receiver box on an almost continual basis any time you're using your Internet connection.  Signals coming from the satellite are said to be 'downloads' and signals coming from your computer are said to be 'uploads.'

So, signals the satellite sends, such as browser windows and web pages, are downloads.  Signals you send, such as emails containing attachments and web order forms, are uploads.

Many other people are probably using the same signal bandwidth at the same time you are, especially during peak times.  When you're sharing the bandwidth, everyone's speed does slow down somewhat.  When shopping for the best Internet connection possible, this typical speed is the number to watch out for.

Loading web pages is what most people do when they are using the Internet.  When you click on a blue hyperlink on a web page and go to another page, your browser loads many text files, picture files, and sometimes video files or scripts.

These items deliver information to you and let you interact with the web site.  More and more websites are including hidden scripts that make objects on the page flash, scroll, and pop up.

The more complex a web page is, the longer it takes to load into your browser window.  That's where a high-speed broadband satellite Internet connection comes in to play.  The download speeds coming from the satellite are 600 kilobytes per second at peak times when many people are using the same band width.

This is super fast!  At times when few others are using the bandwidth, web pages download at a 1 megabyte per second rate, which is so fast even the most complex pages seem to appear instantly.

Upload speeds also vary depending on the time of day.  If you attach a photo to an email then click ‘send', the broadband satellite signal sets to work uploading the file to your email service provider to send on to your friends.  The bigger the attachment, the longer it takes to forward the email to the email provider.  Top upload speeds for satellite broadband are usually 128 kilobytes per second, and peak hour speeds can drop to 80 kilobytes per second.

You can usually choose between various broadband satellite Internet packages to choose the right speed for your family.  Most home users find the download and upload speeds with the basic package to be plenty of speed to check email and look at pictures and videos.  Someone with a home-based business might want a speed upgrade, and anyone who does graphic design, website design, or Internet publishing would certainly need the top speed available.

What is the use of Network Monitoring?

What is the use of Network Monitoring - Tips to Monitor or Manage your Network

Author: rahul gupta

What is network monitoring?

The term 'network monitoring' can be defined by a system that ceaselessly monitors a network of computers for bad or slow constituents and informs network administrators about the situation via email or any other notifying system. It is an integral part of network management.

[caption id="attachment_1121" align="aligncenter" width="650"] What is the use of Network Monitoring?[/caption]

Why is it important?

Availability is very important to measure the quality of a network today. If a network does not have problems, its availability would be 100 With the increasing need for such network availability it has become imperative for businesses to switch to more sound network monitoring solutions. The network administrator needs to anticipate problems. The network will fail at any point in time, and that's inevitable. The important thing is to become aware of the problem immediately and also know its cause in order to fix it quickly. Only monitoring the network continuously will ensure its uninterrupted availability and productivity.

 What is the current scenario?

Even today, there are computer networks that are not yet sufficiently monitored, in part because the interoperability between devices is handicapped by excessive protocols and incompatible interfaces. However, 'handicapped' does not imply an impossibility thanks to the advanced surveillance systems, and despite the limitations of old technology there is much hope for the near future. Current network monitoring systems integrate various technologies into a single control system and overcome the difficulties of yesteryear network management systems.

Why switch to network monitoring?

In a world where time is money, network failures can significantly reduce the productivity of a business. Network monitoring systems do not prevent problems but report them at the shortest notice. Since the whole process is automated there is little room for a false alarm. In network systems which incorporate tens and hundreds of computer devices, one cannot afford the luxury of looking for a problem manually. The issue has to be reported immediately so that it can be fixed in quick time before the problem is aggravated. With remote access features it has become all the more convenient for network administrators to fix issues with minimum delay once they have been reported. Real-time monitoring nullifies the need for carrying out manual checks on backups, antivirus applications, event logs, hard disk space and so on.

 Benefits

The benefits of an integrated monitoring system are listed below:

• Increase in the reliability of systems and equipment


• Rapid diagnosis of events


• Greater flexibility in the operational handling, maintenance and reconnection


• Improved response time


• High degree of flexibility for future extensions


• Reduced costs of operation and maintenance


• Prediction of potential problems in real time

 Conclusion

The current competitive scenario of the market has forced companies to embark on a constant search for greater efficiency, better supply quality and lower costs. This context has led to a change in the maintenance philosophy, accelerating the shift to more dependable network monitoring systems. Network management systems have thus adopted network monitoring as one of the main tools to cope with this change without jeopardizing the safety and reliability of operating systems, while predicting and diagnosing potential problems.

What is Automated Translation?

What is Automated Translation?

Author:ajax

Language is foundational to an enterprise's longevity and success in today's global market. The first concern of any enterprise looking to expand its global footprint must revolve around how to utilize language technology and use this innovation to communicate their corporate services and products. One of the most important obstacles in global communication is the lexical differences in languages. Hence, language translation is necessary for communicating in foreign languages. Unless and until the foreign customers infer the meaning of the marketing messages correctly, there is less than one percent chance of their buying it. Therefore, in order to gain foothold in foreign markets, enterprises need to translate content into different languages in near real time. This is easily possible through automated translation. But, what is automated translation?

[caption id="attachment_1105" align="aligncenter" width="630"] What is Automated Translation?[/caption]

Automated translation is the translation of text by a computer, with no human involvement. Pioneered in the 1950's, automated translation is also referred to as machine translation, automatic translation, or instant translation. Automated translation helps enterprises to communicate with customers in the right channel, in the right language and at the right time.

Automation translation systems are of two types namely,rule-based and statistical. A rule-based system uses a combination of language and grammar rules, together with dictionaries of common words to generate a translation.

While statistical systems learn rules automatically by analyzing large amounts of data for each language combination. These systems can be trained for specific industries or companies using additional data relevant to the domain.

Automated translation delivers benefits in several ways:

Accelerates Human Translation Productivity - It speeds up human translation productivity by providing an initial translation for human post-editing to deliver translated content faster.

Improves Customer Service and Satisfaction -It makes content easily accessible to global customers to improve customer service and satisfaction – with on-demand translation of support knowledge base content, cross-language chat, and multilingual email support.

Supports More Languages in Quick Time - It helps to grow revenue from new markets by supporting more languages in quick time.

Enhances Employee Collaboration - It improves employee collaboration by helping employees understand non-native language communication (like emails, documents and websites) through a general ('gist') translation.

Thus, automated translation accelerates global communication to support new market expansion, deliver a positive customer experience, and enable instant access to information in a user's preferred language.

The internet driven technological revolution has altered the way businesses function and have left a deep impact on the global economy. With more tech-savvy customers to serve, business enterprises are faced by challenges to meet the expectation of every individual customer so as to stay successful and relevant within the globally competitive landscape.

Languages are the medium of communication and translation is the process of communicating the meaning of a source language text to a target language text. Translation came into existence after written literature came into use and human translators with their spill-over of source language idiom and usage play a major role in the way most of the languages have been shaped.

What is a Digital Photo JPEG File?

What is a Digital Photo JPEG File?

By Ziv Haparnas

Digital photos are stored as files on memory cards and computer hard disks. They can be stored in different file formats (each format has a unique file extension). Digital photo files can be compressed to save storage space and can use a standard or a proprietary format.

[caption id="attachment_1090" align="aligncenter" width="507"] What is a Digital Photo JPEG File?[/caption]

Digital photos are saved as digital files on electronic media. These digital photo files are a collection of bytes. JPEG is a standard file format for storing such digital photos. The JPEG format supports compression and allows very efficient high quality storage of digital photos. When using the JPEG format any software from different vendors that adheres to the standard can create and process JPEG files.

JPEG - Joint Photographic Experts Group

The JPEG file format was designed by a special industry group for the purpose of storing and compressing high quality digital photos. Later on JPEG became an ISO standard and it is probably one of the most popular formats for storing digital photos today. JPEG files are also known simple as JPG files (named after their common file extension .JPG).

The design goal of the group was the efficient storage of digital photographic files while maintaining their original high quality (or quality which is as close as possible to the original one). JPEG files can support lossless compression but since lossless compression is inefficient when compressing digital photos it is hardly used. In most cases JPEG files use lossy compression to efficiently represent digital photos.

It is easy to understand the motivation for such efficient compression by using an example: Digital photos files are built of pixels each one has a value representing its color and intensity. Each pixel occupies 3 bytes (one for Red, one for Green and one for Blue - representing the color and intensity of the pixel). If you shoot a photo using an 8 mega pixels digital camera the photo will have 8000000 pixels each one occupying 3 bytes. The total file size would be 8000000*3=24000000 or 24Mbytes. This is a very big file. Big files are hard to manipulate they take a long time to send by email, they occupy large storage space and they take longer to load. If that same file was compressed into a JPEG digital photo file its size would reduce to about 3Mbytes - a much more manageable file size.

JPEG files are extremely efficient in compressing digital photos. They are using compression methods that were specifically designed for digital photos and take advantage of digital photos attributes that allow a more efficient representation of pixels. The JPEG format standardized the way a digital photo is represented and suggested ways to compress digital photos. Using this standard software from one vendor can compress and create a JPEG digital photo file while software from a different vendor can read and process it. There are many different compressors implementations that differ in the quality of the compressed photo. Also - the digital photo compressor can be set to different levels of compression. When using a very aggressive compression setting the digital photo file can be very small - the side effect however is degradation in quality - most noticeable is the appearance of large square areas with the same color and pattern.

JPEG files are the most commonly used ones by digital cameras to store compressed digital photos on memory cards and computer hard disks as they result in small file sizes and hardly any noticeable photo quality degradation. Most cameras also let the user set the level of compression applied to the digital photos - usually three level are provided: low, medium and high - where low results in minimal file size reduction but superior quality and high results in the smallest files but the highest degradation in quality - in most cases however that degradation is hardly noticeable by the amateur photographer.

What is the Difference Between Data Retrieval and Information Retrieval?

What is the Difference Between Data Retrieval and Information Retrieval?

By Mridz Boin

As we are moving into the information age there is a need to secure data transmission and also to store and retrieve the data and the information. Information Retrieval Systems are increasing with the advent of the technology.

[caption id="attachment_1087" align="aligncenter" width="512"] What is the Difference Between Data Retrieval and Information Retrieval?[/caption]

Let us fist talk about the basic differences between the data and the information.

DATA:

• It is the raw fact.


• For its retrieval it needs to be fully mentioned. If the file name or the document name is not known or is case sensitive, there are chances for the system to fail and do not retrieve any document.


• Examples of data are a piece of paper, a book, an algorithm.


• In the above examples their location is not known and hence the meaning cannot be given to this data

INFORMATION

• Information is processed data.


• For its retrieval a partial information is enough for its evaluation. Hence, the system never fails.


• Examples of information are a piece of paper on a table, a book in the shelf, a bubble-sort algorithm.


• In the above examples their location are known and hence they have a specified meaning.

Data retrieving systems can be found in the operating system search. Windows search is a best example for the data retrieval system. you would have to specify the exact name of the file that you desire. Where are information retrieval systems are like web search engines. The best known is Google. It processes the natural language and produces the output in encompassing the entire set of documents matching the query.

It is very much important in these days to retrieve the data at a faster rate. Earlier there used to linear search mechanisms where in the entire set of documents in the database are read and then sorted according to the query and displayed. This had varied complexities and took greater amount of time compared to the advanced techniques available these days.

In an information retrieval system, the documents are scanned for the query. To decrease the computation time of the system, the documents are scanned only for the repeated key words which are considered relevant to the document. The output displayed sends a feedback as an input for the next query. In this way with every query there is an increase in the performance of the system.

There should be more and more information retrieving systems to reduce the time of searching a document and this is done with the help of indexing.

What is Data Mining? Why Data Mining is Important?

By Flori Lee

Searching, Collecting, Filtering and Analyzing of data define as data mining. The large amount of information can be retrieved from wide range of form such as different data relationships, patterns or any significant statistical co-relations. Today the advent of computers, large databases and the internet is make easier way to collect millions, billions and even trillions of pieces of data that can be systematically analyzed to help look for relationships and to seek solutions to difficult problems.

[caption id="attachment_1084" align="aligncenter" width="620"] What is Data Mining? Why Data Mining is Important?[/caption]

The government, private company, large organization and all businesses are looking for large volume of information collection for research and business development. These all collected data can be stored by them to future use. Such kind of information is most important whenever it is require. It will take very much time for searching and find require information from the internet or any other resources.

Here is an overview of data mining services inclusion:

• Market research, product research, survey and analysis


• Collection information about investors, funds and investments


• Forums, blogs and other resources for customer views/opinions


• Scanning large volumes of data


• Information extraction


• Pre-processing of data from the data warehouse


• Meta data extraction


• Web data online mining services


• Data online mining research


• Online newspaper and news sources information research


• Excel sheet presentation of data collected from online sources


• Competitor analysis


• Data mining books


• Information interpretation


• Updating collected data

After applying the process of data mining, you can easily information extract from filtered information and processing the refining the information. This data process is mainly divided into 3 sections; pre-processing, mining and validation. In short, data online mining is a process of converting data into authentic information.

The most important is that it takes much time to find important information from the data. If you want to grow your business rapidly, you must take quick and accurate decisions to grab timely available opportunities.

What is a Colocation Center?

What is a Colocation Center?

By Amy Nutt

As businesses go more global and become more adept at outsourcing, there will be an increased demand for virtualization and servers located off-site. This is the situation with many companies who store their data in places away from the office grounds. In layman's terms, Colocation is simply the process of hosting or getting space in a data center to either increase their server's capabilities in terms of space or just data storage. Many companies are opting for this method of data storage as backup for their on-site data.

[caption id="attachment_1076" align="aligncenter" width="560"] What is a Colocation Center?[/caption]

Colocation centres also known as data centers are specifically built for the purpose and have all measures taken to protect your data anytime. Given the nature of the data stored on their servers, all Colocation service providers know the import of not joking with information. Their servers are often equipped with some of the best if not customized encryption software making it impossible for even the guys working at the center to decrypt the data. Colocation has a lot of benefits and some of them are:

1. Reduced Costs and Expenses: Like it or not, installing new servers every time costs money. But with Colocation services, if you decide to move all your data off-site, your costs will be drastically reduced. The server you will be given will strictly be yours meaning that nobody except you will be able to access the data.

2. Pricing is far cheaper: While Colocation generally guarantees that you have access to your data anywhere in the world by a mere click of the mouse, the relatively cheaper pricing makes it a very attractive option to other forms of data storage available.

3. Flexibility and Bandwidth extension: Small business owners can often buy bandwidth in bits. Thus giving them the opportunity of extending or adding to their bandwidth anytime they want one without unnecessarily getting broke.

4. Complete access to the server: When you pay for a space in a Colocation center, the space is strictly meant for you alone. So only you will have access to your data except you give out the password and user ID. You can modify the server as you wish, increase your bandwidth if you want, install applications, encrypt and decrypt your data, upgrade the server as you wish and execute anything you want. Bottom line, you own the monopoly.

5. Safety: In case of any mishaps, you can rely on the centers to preserve your data. While the cost of preserving the data may be too much to handle for a start up company, getting an account with a Colocation company will ensure that your data as they often have anti-inflammatory measures that will seal the server rooms and suck out the oxygen in cases of an inferno, thus leaving the rooms near untouched. Most Colocation companies also have fibreglass protecting their servers in the data rooms.

In all, if you want to be sure of how safe your data is, you can go on a data center virtual tour. This will give you an idea of how protected your data will be in their care.

What is a Computer Forensics Expert Witness?

What is a Computer Forensics Expert Witness?

By Jason Perry

What is an Expert Witness in the field of Computer Forensics? The most simple answer is a person who goes to court to testify regarding the accuracy and findings from the computer forensics service. In a nutshell, that is it. However, there is a lot more to being an Expert Witness in the field of Computer Forensics and E-Discovery.

[caption id="attachment_1071" align="aligncenter" width="650"] What is a Computer Forensics Expert Witness?[/caption]

With the increased usage and dependence on the Internet - for corporate and individual communication - electronic communication is now the standard and 'paper' communication is the new exception.

• 80% of all corporate data is stored electronically


• 95% of new data is stored electronically (approximately 80% of this information stays in electronic format).

As a result, in almost every legal matter, critical and relevant evidence will be stored electronically. Proper collection and examination of this evidence is critical to avoid spoliation, to preserve the evidence, and to manage cost.

An Expert Witness is a specialized and quickly growing field of investigation within Computer Forensics and E-Discovery. And as such, these individuals are a leading defense, or offense - depending on which side of the litigation you are on, up corporate America's sleeve against cyber crimes and prosecuting 'hackers'. An Expert Witness service typically works closely with a Computer Forensics investigator, or perhaps has the credentials and experience of both.

Computer Forensic investigators uncover the depth of a security breach, recover data that has been corrupted or intentionally deleted, identify how a 'hacker' got past the security checks and if fortunate enough, identify the individual who caused the damages. The term 'hacker' can either be an individual on the Internet, an employee, or a spouse looking to steal or destroy data.

Expert witness service provides testimony, documentation and witness preparation to help present discovered electronic data in legal proceedings to help you prove and win your case.

Should your company, or yourself, need the service of an Expert Witness for a case dealing with Computer Forensics and E-Discovery, make sure that the computers which could be involved in the case are secured from use and contact a Computer Forensics service to discuss your situation.

What is Computer Forensics?

What is Computer Forensics?

By Jason Perry

It is the end of the day and it has been discovered that several critical files are missing from your file server. That alone is normally is enough to freak out most server administrators, but this specific incident also happened to be on the exact same day a particular employee was 'terminated'. As you recall that individual, had access to the missing data, but as far as you know, she didn't seem like the type of person to do something malicious. Then again, you noticed she seemed pretty upset as she was clearing out her desk that day too. You begin to wonder if there is a connection between the two, and if so, how you collect the necessary information to present to your manager.

[caption id="attachment_1068" align="aligncenter" width="650"] What is Computer Forensics?[/caption]

No, you are not imagining a scene from CSI or Court TV. This situation happens daily in real life and may have happened, or could happen, at the company you work for. Remember Enron?

What is Computer Forensics?

Computer forensics, sometimes known as "Digital Forensics" or "Electronic Evidence Discovery", is often described as "the preservation, recovery and analysis of information stored on computers or other electronic media".

Computer forensics has quickly become a vital tool and source of information for criminal investigators, corporate counsel, and prosecutors. Computer forensics investigators use their skills to identify and restore formatted, corrupted, deleted or hidden files from computers or other electronic media while maintaining crucial data trails, time & date stamps and accurate chain of custody & controls. They also obtain access to protected or encrypted data by using specialized software.

In addition, with the increased usage and dependence on the Internet, for corporate and individual communication, computer forensic investigators are equip to analyze emails, Internet searches, file transfers, online account transactions and anything else a computer is used to do over the Internet.

How do they do it?

Computer forensic investigators typically focus on 4 areas when investigating a potential incident. There are other areas of attention as well, but the following are the most common. Including illicit and damaging activities that could damage your company's reputation.

Saved Files

These are files that can be viewed on the computer. This is usually a non-intrusive task to obtain these files.

Deleted Files

These files are just that...deleted. They are either in the 'trash' or require special software to 'capture and restore' the files. This is usually a non-intrusive task to obtain these files.

Temporary Files

These files are typically generated from browsing the Internet, working on a document, some types of back-up software as well as certain software installations for example. Identifying these requires specialized software and is an intrusive process.

Meta Data

This information typically is associated with the details of a file or document. Such as, the date the file was created, modified and last accessed. Additional information that could be captured could include the original creator of the file (of course that information depends on the original installation of the application) as well as anyone who has ever accessed the file. Identifying these requires specialized software and may or may not be an intrusive process.

What would Computer Forensics Service be used for?

There are several possible uses for this type of service. The most common applications of computer forensics are as follows:

• Divorce Cases


• Electronic Investigation


• Expert Witness Service


• Corporate E-mail Investigation


• Litigation Support


• Intellectual Property Disputes


• Investigation and Discovery Litigation Programs


• Insurance Fraud Cases


• Corporate Investigations


• Corporate Counsel Support


• Electronic Records Management

There are many reasons why you, or your company, may require the service of a computer forensics investigator. If you suspect that you may have an incident requiring computer forensic service, or electronic evidence discovery & analysis, you should secure the computer from further use and contact an experienced computer forensics service company.

What is Data Recovery?

What is Data Recovery And Why Does It Matter To You?

By Peter Bacon

To be precise, the phrase "data recovery" refers to the process whereby data is saved from storage media that has either been corrupted, damaged, failed, or made inaccessible for some reason. When data cannot be accessed the way it normally is, then we have to seek ways to recover it. This also happens to such entities as hard disk drives on computers, compact discs, DVDs, RAID, storage tapes, and other forms of electronics.

[caption id="attachment_1066" align="aligncenter" width="650"] What is Data Recovery?[/caption]

Data loss typically comes about as a result of either physical damage to the device storing the data or else logical damage done to the device's file storage system. The latter type of damage results in the data being unable to be mounted by the host's operating system.

The term "data recovery" might also refer to the process whereby information that has been deleted is retrieved and secured from a storage system for forensic purposes.

Physical damage can afflict storage media in a variety of fashions. For one thing, a compact disc storing pertinent data can be affected by having one of its layers or its metallic substrate scraped off of it. Hard drive disks often experience mechanical failures, such as failed motors or head crashes. Quite often, tapes simply break down.

The problem with physical damage is that it always causes the loss of at least some - if not all data on the storage device. Sometimes the system's logical structures can be seriously damaged as well. Logical damage must be dealt with immediately in order for any data recovery to occur.

It is much more common for logical damage to occur than physical damage. Most of the time, logical damage comes about as the result of a power outage, which will prevent the structures of the file system from being written to the desired storage media. As a result, the file system remains inconsistent. If your system is behaving in a strange fashion or crashes, you might lose some pertinent data that will have to be recovered. Thankfully, it is much easier to do this when it is a case of logical damage, rather than physical damage.
