Types of Software

 

A computer to complete a job requires more than just the actual equipment or hardware we see and touch. It requires Software — programs for directing the opera­ tion of a computer or electronic data.

 

Software is the final computer system component. These computer programs instruct the hardware how to conduct processing. The computer is merely a general-purpose machine which requires specific software to perform a given task. Computers can input, calculate, compare, and output data, as information. Software de-

termines the order in which these operations are per­ formed.

 

Programs usually fall in one of two categories: system software and applications software.

 

System software controls standard internal computer activities. An operating system, for example, is a collection of system programs that aid in the operation of a computer regardless of the application software being used. When a computer is first turned on, one of the systems programs is booted or loaded into the computers memory. This software contains information about memory capacity, the model of the processor, the disk drives to be used, and more. Once the system software is loaded, the applications software can start to work.

 

 

System programs are designed for the specific pieces of hardware. These programs are called drivers and co­ ordinate peripheral hardware and computer activities. User needs to install a specific driver in order to activate his or her peripheral device. For example, if you intend to buy a printer or a scanner you need to worry in ad­ vance about the driver program which, though, commonly go along with your device. By installing the driver you «teach* your mainboard to «understand* the newly at­ tached part.

 

 

Applications software satisfies your specific need. The developers of application software rely mostly on marketing research strategies trying to do their best to attract more users (buyers) to their software. As the productivity of the hardware has increased greatly in recent years, the programmers nowadays tend to include all kinds of gimmicks in one program to make software interface look more attractive to the user. These class of
