Answer 2

Answer:

A computer is a piece of electrical equipment that functions in accordance with the programmes that are stored in its memory. The information processing cycle has four phases: input, processing, output, and storage. Any physical component that transmits data to the computer qualifies as an input device. The computer sends information to an output device, which converts it from machine language into text that people can read.

Explanation:

Step 1:A physical component called computer memory is utilised to temporarily or permanently store data or information. Random Access Memory (RAM) and Read-Only Memory (ROM) are the two main categories for computer memory (Read Only Memory). RAM is a read-write kind of memory. Its memory is volatile. A read-only memory is a ROM. This memory is non-volatile. Programs and data are stored in bulk on secondary storage, also known as auxiliary storage.

Step 2: Hardware and software are the two major components of a computer. Any physical component of a computer is referred to as hardware, and any collection of instructions used to control hardware is referred to as software. System software and application software are the two categories of software. Programs called system software coordinate the operations and features of hardware and several other programmes. Programs known as application software assist users in resolving certain computing-related issues.
