How to Move Data Between Computers

How to Move Data Between Computers

Almost all of us have upgraded our computer to a newer one and faced the problem of how to get our data transferred over to the new hard drive. This is an important task to learn since you will probably need to do it several times throughout your life. Probably the most helpful piece of advice for anyone in this position is to understand your operating system’s directory structure. Once that is understood, you have three basic options to transfer data:

• Manually/Sneakernet
• Over a network
• Direct connection

The first, and most basic, method of moving your data to your new computer is by using either something like a portable USB hard drive or a USB pen drive. Plug the device into your old computer and wait for it to install the driver, if not already done. Look under My Computer, or Computer, for the USB device. It will have its own drive letter, such as D: or E:. What I like to do is double-click on it and position the window on the right-hand side of my desktop. Next, I open my C: drive on the left-hand side, which is my computer’s hard drive, and if you’re using Windows XP go into Documents and Settings, yourusername. If you’re using Windows 7 or Vista, look under Users, yourusername. The vast majority of your personal data will be located either under Desktop and My Documents. Copy both of these folders over to your USB device. You may have to do multiple copies if your drive isn’t big enough to hold everything at once. Alternatively, you may choose to burn a CD or DVD of your data.

A Second option is to simply copy your files over a network. Whether at home or at work, probably the easiest way to do that is to temporarily share your entire C: drive.

This definitely presents a potential security hazard but for the quick transferring of files it will be okay. For XP, go back into My Computer and right-click your C-Drive. Choose Sharing and Security, acknowledge the security warnings about sharing the root (entire) drive and check Share this Folder on the Network. On Vista or Win7, right-click the C-Drive and choose Share with, Advanced Sharing. Check Share this folder. At this point, both computers are sharing their entire hard drives. You may go to either computer and browse your network for the other shared hard drive. Simply drag and drop the files to your new computer from the old. Don’t forget to remove sharing when finished.

The final method is by using either a USB cable or a Crossover cable and hooking it up to both computers. By plugging a crossover cable into each computer’s network port, you can transfer data without the aid of a network or USB device. This can be quite tricky for the layperson to do so I would not recommend it. You must launch a command prompt and type ipconfig to determine each computer’s IP address. Share your entire hard drives, as detailed above, and press the Start button. In the Run or search box, type \ipaddressofothercomptuer\sharename. This should connect you to the other computer for data transfer. A far simpler method is through the use of a USB Transfer Cable. This just plugs into a USB port on each computer to establish a connection between the two. With XP you may need to install software from the CD that came with the cable. On newer operating systems you need only follow the prompts.

As you can see, there are three basic ways to transfer files to a new computer: manually, network, and direct. Each method has its pros and cons. Things to consider are if you are on a corporate, domain network, what version your operating system is, and your experience level. In addition, think about how much data you need to move and whether or not you need a backup copy when making a decision about what method to use. The ability to transfer files between computers is a great skill to possess.

Look around you and you will notice the extreme technological buzz all around. With cellular phones, wireless connections to the world of computers where every other day new innovations take place. It may not be wrong to argue that how would anyone live in today’s fast paced environment without a computer. Since computer is not anymore restricted to programming merely as there are so many things that can be done through and with computers especially in the academic world. These days it is almost impossible to survive as a student without a computer. This article highlights some points where computers have become a real necessity for nearly everyone.

Homework and Assignments

From junior levels of education to the senior levels computers are utilized for learning purposes. During college studies computers provide a research platform from where any type of information can be accessed on any given research topic. Students can utilize computers to write their term papers, essays and research papers in user friendly application programs. They can use Microsoft Word to write any sort of document and make changes according to the required specifications in the writing format.

Social Networking

It is believed that certain social networking websites such the face book, twitter and MySpace could become the future search engines taking over the traditional search engines such as Google or Yahoo. The social networking websites can be used for educational purposes where students can share massive amount of information on any topic. They can argue on current trends and events in the world of academia and guide one another about the useful resources on the internet.

They can keep in touch with their instructors or professors to remain up-to-date about their ongoing classes in a particular subject.

Computer Support For Optical Mouse

Computer Support For Optical Mouse

Optical mouse was a major technological leap in the last decade in the 20th century. Before this computer peripheral was invented, mechanical mouse,which was developed in the early 1970s, was the most widely used device for clicking and pointing.

Background

Optical mouse was invented by two independent researchers in the 1980s. So there were two variants. One variant was developed by Richard Lyon of Xerox Corporation. In this type off optical mouse, 16 pixel light image sensor, combined with motion detection equipment, was used to track the movement of light dots in a dark field on a print media. Another type of optical mouse was demonstrated by Steve Kirsch, who employed an infrared sensor and infrared LED to find out grid lines  printed with infrared absorbing link on a special metallic medium. Later, Agilent Technologies designed and developed an optical mouse in 1999, which employed a small camera that shoots thousands of pictures every second to find out the position and speed.

Operation Of Optical Mouse

There are several methods adopted by optical mouse technologies, such as Laser interferometry, slit wheel detection,camera based movement detection, etc.

Laser Interferometry

In this laser based technology, light waved are generated by a laser source and directed towards a surface. In turn the surface reflects some the light signals back to the laser source which results in mixing the reflected light signals with the emitted light signals. Thus partial cancellation of light signals occurs. The frequency of the reflected light gets changed by the movement of the surface, which is known as Doppler effect.

The difference between the frequency of emitted light and the reflected light determines the degree of light cancellation, which is detected by a photo diode sensor at the laser source. The movement of the surface relative to the sensor determines the power fluctuation. The path of the movement is sensed by changing the laser frequency. Two orthogonally located lasers detect the two dimensional movements.

Slit Wheel Detection

This old ball based mouse technology employs optical sensors to sense the movement of the ball. Two rollers connected to the wheels with slits are rotated by the ball. When the wheel rotates, the path of the light between the two sensors and the infrared emitter gets blocked. The sensors are aligned with one on the top of the other. As the wheel turns the light strikes one of the sensors. The sensor which detects the light provides the information about the movement.

Camera Based Movement Detection

This is the technology adopted by most of the optical mouses. Special mouse pads are not required for smooth optical mouse operation. In this technology, an optoelectronic device which is nothing but a small low resolution video camera , is used to snap successive images of the surface on which the mouse operates. The relative motion is detected by translating the movement of the mouse into movement of the cursor. The process is known as digital image correlation. Image sensors photographs naturally occurring textures on the surfaces like mouse pad, cloth or wood. These surfaces when illuminated by a light emitting diode at a grazing angle, cast different types of shadows. Images of these surfaces are recorded continuously and comparison of these images provides the detailed picture of the mouse movements.

Network Support For Optical Mouse

Since optical mouse does not have rolling parts, less maintenance is required for it. However problems might arise because this device does not work properly on transparent and shiny surfaces. Also devices with less image processing power, cannot track fast movements. In case such problems occur, taking the help of online Computer support is the best option. Most of the optical mice are energized by battery. Sometimes optical mice do not work properly because of battery issues. Also the infrared elements in the mouse might malfunction. Nowadays many network support providers are providing round the clock solutions to such problems.

Nowadays it is very difficult to find a business job or educational and entertainment activity in which the computer is not used. The timely outcome of a business process or a project work depends on the computer speed. A  slow computer not only hinders the progress of the job but delays it and in some extreme cases halts it completely. When the computer is used for entertainment, the slow speed causes annoyance. Sluggish computer slows down communication speed which in turn delays the business process. That is why a slow computer is considered as a bane. There are many causes due to which a computer may become slow. Some of the most common causes and the solutions are discussed below. For other uncommon and rare causes, the help from an experienced PC support provider should be taken.

Viruses, Spyware, Adware And Malware:

Viruses,Spyware,Adware and Malware are basically malicious softwares which make the computers slow. Every computer is vulnerable to these nasty softwares. Viruses are small programs which could cause lots of troubles to the computer users by corrupting stored data and making the computer malfunction. Spywares are software programs,specifically designed to gather personal information about the computer user without the user’s knowledge. Personal information includes the list of websites visited by the user, the user name ,password,etc. These confidential information could put the user’s accounts in jeopardy. Adwares are special programs designed by internet marketing agencies to accumulate information about the habits and preferences of the customers.  The intention is to market their products more effectively. These vicious softwares make the computers run slow because the cookies and trojans take up processor time and occupy memory space. To get rid of this menace, the anti virus and anti Spyware softwares should be updated and run regularly.

Every operating system software needs a minimum amount of RAM and hard disk memory. It must be ensured that the proper hardware is in place before running an operating system on a computer. To upgrade system resources, an experienced tech support provider should be consulted.

Insufficient Disk Space:

Sometimes if sufficient disk space is not available, the computer may become slow. The files, which are not required any more, should be deleted to free disk space. Lot of disk cleanup tools are available with network support providers. Such tools could be used to delete temporary internet files,downloaded program files,Recycle Bin files,etc. Among these files, temporary internet files occupy maximum memory space.

Hard Disk Errors:

The integrity of the files,stored on the hard disk, should be checked periodically. After prolonged use of the hard disk, bad sectors might be developed. Physically bad sectors slow down the performance of the computer. To detect whether any bad sector is developed or not, disk error checking utility should be run regularly. This utility could be easily obtained from many PC support providers.

Large Number Of Desktop Files:

If the desktop of the computer is dotted with files, it could make the computer run slow. To improve the performance, the desktop should be kept as cleaned as possible.

Network Support For Improving The Computer Performance:

The most common causes for poor computer performance are discussed in details. The computer users could easily get rid of these problems with the help of a computer support providers. For other unknown or uncommon causes, an experienced tech support provider should be consulted.
