USING SOFTWARE

Software is the set of programs, procedures, and related documentation associated with a computer system. A program is a coded set of instructions that interprets the information you give to the computer with the keyboard or a mouse, and directs your computer to carry out a task.

Different kinds of software perform different kinds of tasks. Examples kinds of software are operating systems, such as MS-DOS, Windows 95 and its enhanced versions and programs Microsoft Excel and Microsoft Office. There is a wide variety of software programs including word processors, accounting packages, computer-aided design systems and games.

The operating system gets your computer running and controls the operation of your computer's activities. It manages the flow, entry, and display of software and data to and from each part of your computer system. To run a program, you first need to run the operating system. Some years ago the Microsoft disk operating system (MS-DOS) or a computer manufacturer's version of MS-DOS was the operating system most widely used with personal computers. Nowadays it is Windows 98, 2000, XP and others.

When you start a program, you see information on your screen, such as menus and commands. While you are using a program, the operating system is managing your computer's activities. It moves instructions and files from one part of your computer system to another as you choose commands and type information.

What is MS-DOS?

MS-DOS – is one of the first operating systems that look after the running of your computer; and like other operating systems, manages the flow of information to and from the various parts of your computer systems. It lets you create and keep track of files, run and link programs, and make use of peripheral devices (for example, printers and disk drives) attached to your computer.

Because your computer can run with one of several different operating systems the operating system is not built into the computer. Instead, it is loaded from disk when the computer is started up.

Once the operating system has been loaded into the computer's memory the disk from which it was loaded may be removed if required. The operating system needs to be reloaded only if part has been overwritten (when using very large programs, for example) or when the computer is restarted. You work with MS-DOS by typing or choosing commands, which direct your system to perform these tasks:

- Manage files and directories;

- Maintain disks;

- Configure hardware;

- Optimize the use of memory;

- Speed up programs;

- Customize MS-DOS;

There are two ways you can work with MS-DOS – by using MS-DOS Shell or by typing commands at the command prompt.

The MS-DOS command line is where you type commands. The command prompt indicates that you are at the command line. The prompt may be the drive letter followed by a backslash (C:\or A:\, for example) or a backslash and the name directory (C; \STATUS, for example).

The letter indicates which disk drive is the current drive. MS-DOS searches the current drive for the information it needs to process the commands you type.
