A computer is
a general purpose device which can be programmed to carry out a finite set of arithmetic or logical operations
an electronic device that manipulates information, or "data". It has the ability to store, retrieve, and process data. You can use a computer to type documents, send email, and browse the internet. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more.
an electronic device which is capable of receiving the inputs (data from the user), storing it for a desired period of time, manipulating it according to the set of instructions (called program) and producing the output to the user in desired form. It performs a variety of operations in accordance to the set of instructions.
at its most basic, a machine which can take instructions, and perform computations based on those instructions
definitions you may find some common behaviors of computers such as, except
It is a man-made machine
it is a good program machine
It accepts instructions of a human given in a sequential manner
As per the given instructions, it performs some calculations and does changes for the information fed by human
Since the computer is a man-made digital electronic device, it has a physical structure with several parts like the, except
PC
processor
mouse
key board
Acording Wikipedia, A computer is

arithmetic or logical operations
The above three descriptions are some standard definitions extracted from different information resources available in the World Wide Web, including Wikipedia, the largest free encyclopedia. Meanwhile, a computer can be defined as follows in terms of basic usage of the computer which is more readable for a layman.
A computer is an electronic device that manipulate information, or "data"
an electronic device which is capable of receiving the inputs (data from the user), storing it for a desired period of time, manipulating it according to the set of instructions (called program) and producing the output to the user in desired form. It performs a variety of operations in accordance to the set of instructions.

Such limitations of computer are given below
It cannot correct wrong instruction- if you give the computer wrong instruction, it will not be able to do anything to rectify it. The only thing it can do is to stop functioning till you correct the mistake.
The computer can do only what you tell it to do-you cannot expect the computer give you something which you did not ask
It will give wrong information if you feed it with wrong data- the computer cannot identify what the correct data and what the wrong data are.

Microcomputers is
used by multi-users. In the middle when the computers are ranged from smallest to largest. Used in laboratories
most common type of computers in the society. Can be used at your workplace, at school or on your study desk at home. Used by single user at a time. Small in size. Also called Personal Computers (PCs).
Largest in size. Capable of handling and processing very large amounts of data
quickly.
Used for performing complex scientific and numerical computations such as weather forecasting, fluid dynamics, nuclear simulations, theoretical astrophysics. Sometimes called as “Workstations”

A Personal Computer (Mostly referred to as PC in the community) is
designed as a more user-friendly device to be directly used by the end-user rather having an especially skilled separate computer operator.
