What is a computer, in simple language,
it is a machine that can process data and do calculations. The Term “Computer”
refers to the hardware, software and firmware used to process data. Computers
have been in use since the early 20th century, but they became
widespread in the 1980s with the advent of the personal computer.
So we can
call a computer such an advance electronic device that takes raw data from the
user as input. Then processes that data through a program (set of instruction)
and publishes the final result as output. It processes both numerical and non-numerical
(arithmetic and logical) calculations. What is a computer and know a little
from bed.
What is
Computer?
A computer is an electronic device that can be programmed to automatically perform a set of arithmetic or logical operations. This is the easiest answer to what a computer.
A computer
has three main components: input, processing and output. Input is usually a
keyboard and mouse. The processing component is usually in the form of a
microprocessor or central processing unit (CPU). Output is usually on a display
screen, such as a monitor or television.

How
does Computer work?
A computer
is a device that is used to store, process and transmit data. They are used for
anything from storing files and documents to sending emails.
Computer are
electronic devices that can store and process data through the use of
microchips. The first computer was invented in the 1940s by a team of
scientists led by British mathematician Alan Turing. The computer was designed
to calculated artillery tables for the British Army.
The word “Computer”
is derived from the word “Compute”, Which means “to figure out”. Computers have
been around since 1938 when they were invented by British mathematician Alan
Turing.

Who invented computer?

Contributed in
this computing filed. But out of all these the
contribution
of Charles Babbage is more. because it Was he who first
came out with the Analytical Engine in the
year 1837.
The concept
of ALU, Basic Flow Control and Integrated Memory was
Implemented in
his engine. today's computer Were designed on the basis of this model only. today's
Why his contribution is maximum. That`s why he is also known as the father of
computer.

Definition
of Computer
A computer
is an electronic device that manipulates data according to a list of
instructions called a program.
The term
computer has been in use since the early 17th century, when it
refers to a person who calculating machine. The term continued to refer to
these workers through the 19th century and into the 20th
century and into the 20th century until it was later applied to “a
machine that automatically calculates”.

Work
Input
(Data): Input is the
step in which raw information is entered into the computer using input device. It
can be a letter, picture or even a video.
Process: The data input during the process is
processed according to the instruction. This is completely internal process.
Output: The data that has already been
processed during the output is shown in the form of the result. And if we want,
we can save this result and keep it in memory for future use.
Main
parts of computer
If you have
ever seen inside a computer case, then you must have found that there are many
small components inside, they look very complicated in reality. Now I will give
you some information about these components.

Motherboard
The main
circuit board of any computer is called Motherboard. It looks like a thin plate
but it is holding many things. Such as CPU, Memory, Connectors for hard drive
and Optical Drive, expansion card to control video and audio, as well as
connection to all ports of the computer. If seen, the motherboard is directly
or indirectly connected with all the parts of the computer.
CPU/Processor
Do you known
what is Central Processing Unit i.e. CPU? This is also called it is found in
the motherboard inside the computer case. It is also called the brain of the
computer. It keeps an eye on all the activities inside a computer. The higher
the speed of a processor, the faster it will be able to do processing.
RAM
We also know
RAM by the name of Random Access Memory. This is the short-term memory of the
system. Whenever the computer does some calculation, it temporarily save that
result in RAM. This data is also lost if the computer is turned off. If we are
writing a document, we should save our data in between. By saving, if the data
is saved in the Hard Drive, it can remain for a long time.
RAM is
measured in megabytes (MB) or gigabytes (GB). The more RAM, the better it is
for us.
Hard
Drive
Hard Drive
is the component where software, documents and other files are saved. In this,
the data remain stored for a long time.
Power
Supply Unit
The work of
the power supply unit is to take power from the main power supply and supply it
to other components as per the requirement.
Expansion
Card
All
computers have Expansion Slots so that we can add an Expansion Card in the
future. These are also called PCI (Peripheral Components Interconnect) cards. But
nowadays there are already many slots built-in in the motherboard. Names of some
Expansion Card that we can use to update old computers.
✅ Video Card
✅ Sound
Card
✅ Network
Card
✅ Bluetooth
Card (Adapter)
If you are ever opening the internal
things of the computer, then you should first remove the plug from the main
socket
Computer hardware
and software
We can call
computer hardware any physical device that we use in our computer, whereas
computer software means a collection of codes that we install in the hard drive
of our machine to run the hardware.
For example,
the computer monitor that we use to read, the mouse that we use to navigate are
all computer hardware. The same Internet Browser from which we visit the
website, and the Operating System in which that Internet Browser runs. We call
such things as software.
We can say
that a computer is a combination of software and hardware, both have similar
roles, both can work together.
Type of
computer
A computer
is a type of machine that people use to calculate information. Computers are
often called the brain of the modern world because they are used in almost
every industry and for many different purposes.
There are
two types of computers, Analog and Digital. Analog computers require less power
but require more time to process data, while digital computers require more
power but require less time to process data.
Whenever we
hear the use of the word computer, only
the picture of personal computer comes in our mind. Let me tell you that there
are many types of computers. Comes in various shapes and sizes. We use them
according to need, such as ATM to withdraw money, scanner to scan a barcode,
calculator to do any big calculation. These are all different types of
computers.
1.
Desktop
Many people use desktop
computers for their homes, school and for their personal work. Their design is
such that we can keep them on our desk. They have many parts like Monitor,
Keyboard, Mouse, Computer Case.
2.
Laptop
you must have known about
Laptop which are Battery Powered, they are very portable so that they can be
taken anywhere and anytime.
3.
Tablet
Now let’s talk about
Tablet which we also call Handheld Computer because it can be easily held in
hands.
There is no keyboard and
mouse in it, just a touch sensitive screen which is used for typing and
navigation. Example – I-pad
4.
Servers
A Servers is some type of computer that we use to exchange
information. For example, whenever we search for something in the Internet, all
those things are stored in the server only.
