Text C: "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 opera­tion 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 deter­mines the order in which these operations are performed.

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 be brought in.

System programs are designed for the specific pieces of hardware. These programs are called drivers and coor­dinate peripheral hardware and computer activities. User needs to install a specific driver in order to activate a pe­ripheral device. For example, if you intend to buy a printer or a scanner you need to worry in advance about the driver program which, though, commonly goes along with your device. By installing the driver you «teach» your mainboard to «understand» the newly attached 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 as much as possible in one program to make software inter­face look more attractive to the user. These class of pro­grams is the most numerous and perspective from the

marketing point of view.

Data communication within and between computers systems is handled by system software. Communications software transfers data from one computer system to another. These programs usually provide users with data security and error checking along with physically transferring data between the two computer's memories. Dur­ing the past five years the developing electronic network communication has stimulated more and more companies to produce various communication software, such as Web-Browsers for Internet.
