What is a computer?

2. 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?

3. 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.

4. 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 computerwhat 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.
Softwareperforms 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
