Read the passage below and decide whether the statements are TRUE or FALSE?

A computer is an electronic device capable of manipulating number and symbols, first taking input, processing it, storing and giving out output under a control of set instructions which is known as a program. A general purpose computer requires the following hardware components: memory, storage device (hard disk drive), input device (keyboard, mouse etc.), output device (screen, printer etc.) and central processing unit (CPU). Many other components are involved in addition to the listed components to work together efficiently.

The CPU is can be expanded into three main parts: The ALU (Arithmetic and Logic Unit), The Bus interface Unit, and The Control Bus. The clock is an electronic circuit that gives regular pulses to the CPU. Faster clock speeds mean more pulses to the CPU and the instructions are stepped through faster. The memory chip contains millions of separate memory stores and each of these locations has a unique number. This is known as memory address. The CPU stores data at any of these addresses and fetch the content back when required.

RAM stands for Random Access Memory. These chips store the instructions for running the operating system and any computer application. This memory also stores all the data that is being worked on. RAM is a volatile memory which means that it only stores data while the computer remains switched on. When switched off, it loses all the stored data. ROM (Read Only Memory) on the other hand is a chip with program instructions permanently burned into it. The content is not lost even if the machine is switched off.

A program gives instructions for a computer to operate.
