Only hardware is necessary to make up a computer system.Ģ. Which statement best expresses the main idea of the text? Why do you think so?ġ. A poorly chosen system can be a monstrosity incapable of performing the tasks for which it was originally acquired. The success or failure of any computer system depends on the skill with which the hardware and software components are selected and blended. These complete hardware/software products are called turnkey systems.

The latter may be provided along with the hardware by a systems supplier as part of a computer product designed to answer a specific need in certain areas. These, when brought into internal memory, direct the computer to perform tasks. The former is often simply referred to as 'systems'. Computer software can be divided into two very broad categories - system softwareand applications software. The various peripherals whichinclude inputand/or outputdevices, various secondary memorydevices, and so on, are attached to the CPU. The term 'computer' usually refers to those parts of the hardware in which calculations and other data manipulations are performed, and to the internal memory in which data and instructions are stored during the actual execution of programs. The centerpiece is called the computer, the processor ,or usually the central processing unit (CPU). The basic components of computer hardware are joined together in a computer system. The second part is software- the programs that control and coordinate the activities of the computer hardware and that direct the processing of data.

The first part is hardware- the physical, electronic, and electromechanical devices that are thought of and recognized as 'computers'. Computer system may be discussed in two parts. A 'system' implies a good mixture of integrated parts working together to form a useful whole. In order to use computers effectively to solve problems in our environment, computersystems are devised.
