What is a computer?

A computer is a programmable machine designed to sequentially and automatically carry out a

sequence of arithmetic or logical operations. The particular sequence of operations can be

changed readily, allowing the computer to solve more than one kind of problem.

Conventionally a computer consists of some form of memory for data storage, at least one

element that carries out arithmetic and logic operations, and a sequencing and control element

that can change the order of operations based on the information that is stored. Peripheral devices

allow information to be entered from external source, and allow the results of operations to be

sent out.

A computer's processing unit executes series of instructions that make it read, manipulate and

then store data. Conditional instructions change the sequence of instructions as a function of the

current state of the machine or its environment.

The first electronic computers were developed in the mid-20th century (1940–1945). Originally,

they were the size of a large room, consuming as much power as several hundred

modern personal computers

What does It Means Hardware?

Hardware is a general term for the physical artifacts of a technology. It may also mean the

physical components of a computer system, in the form of computer hardware.

Hardware historically meant the metal parts and fittings that were used to make wooden products

stronger, more functional, longer lasting and easier to fabricate or assemble

Modern hardware stores typically sell equipment such

as keys, locks, hinges, latches, corners,handles, wire,

chains, plumbing supplies, tools, utensils, cutlery and machine parts, especially when they are

made of metal.

What does it means Software?

Computer software, or just software, is a collection of computer programs and related data that provide the instructions telling a computer what to do and how to do it.

We can also say software refers to one or more computer programs and data held in the storage of the computer for some purposes. In other words software is a set of programs, procedures, algorithms and its documentation.

Software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software.

The term was coined to contrast to the old term hardware (meaning physical devices). In contrast to hardware, software is intangible, meaning it "cannot be touched".

Software is also sometimes used in a more narrow sense, meaning application software only. Sometimes the term includes data that has not traditionally been associated with computers, such as film, tapes, and records
