Storage hardware

The purpose of storage hardware is to store computer instructions and data in a form that is relatively permanent and retrieve when needed for processing. Storage hardware serves the same basic functions as do office fil­ing systems except that it stores data as electromagnetic signals. The most common ways of storing data are Hard disk, floppy disk and CD-ROM.

Hard disk is a rigid disk coated with magnetic mate­rial, for storing programs and relatively large amounts of data.

Floppy disk (diskette) - thin, usually flexible plas­tic disk coated with magnetic material, for storing com­puter data and programs. There are two formats for floppy disks: 5.25" and 3.5". 5.25" is not used in mod­ern computer systems because of it relatively large size flexibility and small capacity. 3.5" disks are formatted 1.4 megabytes and are widely used.

CD-ROM (compact disc read only memory) is a com­pact disc on which a large amount of digitized read-only data can be stored. CD-ROMs are very popular now be­cause of the growing speed which CD-ROM drives can provide nowadays. Output hardware

The purpose of output hardware is to provide the user with the means to view information produced by the com­puter system. Information is output in either hardcopy or softcopy form. Hardcopy output can be held in your hand, such as paper with text (word or numbers) or graphics printed on it. Softcopy output is displayed on a monitor.

Monitor is a component with a display screen for view­ing computer data, television programs, etc.

Printer is a computer output device that produces a paper copy of data or graphics.

Modem is an example of communication hardware — an electronic device that makes possible the transmission of data to or from computer via telephone or other communication lines.

Hardware comes in many configurations, depending on what the computer system is designed to do. Hard­ware can fill several floors of a large office building or can fit on your lap.

Exercise 8.6. Which of the listed below statements are true/false. Specify your answer using the text.

1) Computer is an electronic device therefore hardware is a system of electronic devices.

2) The purpose of the input hardware is to collect data and convert it into a form suitable for computer process­ing.

3) Scanner is used to input graphics only.

4) The purpose of processing hardware is to retrieve, interpret and direct the execution of software instruc­tions provided to the computer.

5) CPU reads and interprets software and prints the results on paper.

6) User is unable to change the contents of ROM.

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.
