Installing and Uninstalling of Software
1. Software
Software refers to the set of computer programs, procedures that describe the programs, how they are to be used, it guides the computer at every step where to start and stop during a particular job. Computer software is normally classified into two categories: Application Software and System software, it is not possible to run application software without system software, so without system software it is impossible to operate your computer.

2. Installing software
It s very easy to install software. Simply running the setup program is enough to start the installation. Nearly all installers guide you through an often simple installation process. Some specialist software and huge packages, however, require certain information, like the serial number, serial numbers can also be referred to as product keys, license numbers, etc. Some programs even require two or three numbers, such as Delphi software which not only requires a serial number, but also an authorization key just to install it.
How you add a program depends on where the installation files for the program are located. Typically, programs are installed from a CD or DVD, Internet, network, or from other storage device. If the software is distributed on CD-ROM, inserting the disk into the CD-ROM drive will probably start the setup process.
Some software package distributed in more than one CD, in this case insert the first CD and the installation program will begin, then the setup program will ask you to exchange CD periodically. Be sure that you insert the CD that the program specifies.
