A computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today's computers have both kinds of programming.
Most histories of the modern computer begin with the Analytical Engine envisioned by Charles Babbage following the mathematical ideas of George Boole, the mathematician who first stated the principles of logic inherent in today's digital computer. Babbage's assistant and collaborator, Ada Lovelace, is said to have introduced the ideas of program loops and subroutines and is sometimes considered the first programmer. Apart from mechanical calculators, the first really useable computers began with the vacuum tube, accelerated with the invention of the transistor, which then became embedded in large numbers in integrated circuits, ultimately making possible the relatively low-cost personal computer.
Modern computers inherently follow the ideas of the stored program laid out by John von Neumann in 1945. Essentially, the program is read by the computer one instruction at a time, an operation is performed, and the computer then reads in the next instruction, and so on. Recently, computers and programs have been devised that allow multiple programs (and computers) to work on the same problem at the same time in parallel. With the advent of the Internet and higher bandwidth data transmission, programs and data that are part of the same overall project can be distributed over a network and embody the Sun Microsystems slogan: "The network is the computer."

In information technology, hardware is the physical aspect of computers, telecommunications, and other devices. The term arose as a way to distinguish the "box" and the electronic circuitry and components of a computer from the program you put in it to make it do things. The program came to be known as the software.
Hardware implies permanence and invariability. Software or programming can easily be varied. You can put an entirely new program in the hardware and make it create an entirely new experience for the user. You can, however, change the modular configurations that most computers come with by adding new adapters or cards that extend the computer's capabilities.
Like software, hardware is a collective term. Hardware includes not only the computer proper but also the cables, connectors, power supply units, and peripheral devices such as the keyboard, mouse, audio speakers, and printers.
Hardware is sometimes used as a term collectively describing the physical aspects of telephony and telecommunications network infrastructure.

View previously open Folders after Shutdown or Logoff
If you need to access lot of folders on your home computer or on the network regularly then you can set them re-open automatically, when you will login, shutdown or restart your computer next time. There is no need to open regularly used folders manually, just configure the simple sitting, your computer will automatically reload all the previously opened windows.
By default windows XP disables this option to reload automatically all the previously opened windows, when you login on, shutdown or restart your computer.
Follow the given steps to configure your computer to reload previously opened folders automatically after shutdown.
To edit this feature, you will need to be logged into your computer with administrative rights.
First click on Start button then go to Control Panel.
Open the “Appearance and Themes” option in control panel then click on Folder Options
A small windows dialog box will appear with the title “Folder options”, click on View tab.
Under the Advanced setting section, scroll down to bottom and click the “Restore previous folder windows at logon” option and then click Ok button to save sitting.
Now when you log off, restart or shutdown, your computer will automatically open the previously opened folders from the same location as before.

Disable & Enable AutoRun CD
In windows XP you can enjoy a good feature to run CD or DVD automatically when you loaded it into you CD drives on your computer. This is a defaults feature in windows XP but you can disable and enable it according to your nature of work. In user interface mode there is no option to disable or enable this feature, you must edit the registry of windows and be careful to work registry.
Click Start button then type regedit in Run option then press Enter for next.
Here locate the location to:
HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet\Services\Cdrom
Here you can disable or enable automatically running your CD. Change the value of Autorun to 0 for disable and change the value to 1 for enable. At the end restart your computer for this change.
