A brief History of Computers
Hello guys… Today I’m here to discuss a brief introduction
about computers and main features and history about it.
But before I describe my topic I personally want to
introduce you about a computer. So let’s find out that what is meaning of a
computer and what is its historical background.
What is a computer?
As I’ve read in my course books I want to describe about
computer that computer is an electronic device which can calculate numerical
values and we can get answers to our questions. Computer not only can tell us
answers but it can also store and keep our data for a longer time.
Friend’s computer was a great invention which changed our
life thoroughly. Before this invention we were not expecting that we can save
our data or we can get our answers from a device.
Today computer changed our life thoroughly and made our life
so fast that we do our duties with a single click. We can save a large amount
of data with a single click and for a longer period.
Now I want to tell you a brief history of computer
invention.
History of Computers:
Computer history is almost 2500 years old. As almost every
person knows that first device which invented was abacus. That was a huge
device which was used to measure and calculate values and numerical data. That
device was slow in operation and was huge in size.
In 1642 French Pascal invented a new machine which was made
on cogs and this machine was named as Pascaline. He made this machine to help
his father in calculating tax values.
Charles
Babbage is known as father of modern computers as he
invented a machine which had an input and ability to store some data.
Modern computers are also
built on his theory.
Here are main companies which
are making computers and software.
Microsoft, IBM, Apple, Intel,
HP, Dell,
Here is a little introduction
to these companies.
Microsoft:
Microsoft was founded on 4th
April 1975 by an American person named Bill Gates in New Mexico, United States.
Microsoft was built to ensure the needs of personal computers. Company is
creating various products such as Microsoft windows, Microsoft office, Skype
and many more. Company has approximately 1, 14000 employees. Microsoft is also
offering various services such as one drive, MSN, Bing, Xbox live, MSDN and
outlook.com. Basically Microsoft is known as computer hardware and software
manufacturing company. Company is serving in all over the world.
IBM:
IBM stands for “international
business machines”. Company was built on 16 June 1911 by Charles Runlet Flint.
Its main office is in New York and company is serving in 170 plus countries.
Company is basically built for information technology and has a large amount of
products. IBM has numerous numbers of products and its appliances are sent in
all world.
Apple:
Apple is well known company built in 1976 in
California New York by Steve jobs, Steve wozniak and Ronald Wayne. Apple is
very famous due to its mobile phones known as iphone. Apple Company has many
products such as apple pay, apple store, and online apple store and iTunes.
Apple Company has various products such as I phones, Mac, IPod, Apple TV and OS
X.
Intel:
Intel Company was founded in July 1968. Company
was founded by Gordon Moore. Intel has served everywhere in the world. Intel is
producing many products such as central processing units, solid state drives,
motherboard chipsets, micro processors and memory chipsets. Head quarter of
Intel Company is in California us. Intel has built latest technology.
HP:

Dell:
Dell Company was founded in 1984. Dell was
founded by Michael Dell. Company is headquartered in round rock united states.
Area served by Dell is worldwide. Industry of Dell is producing computer hardware
and software. But now dell is also producing mobile phones and tablets as well.
Michael Dell is not only founder of dell as he is chairmen and CEO.
Common parts of a computer:
Basically a personal computer which is also
known as PC may have followings parts.
Computer, Monitor, Keyboard, Mouse, Printer
& Speakers
A brief detail will be discussed here about
these basic components.
Computer:
Main case of a computer system is computer and
commonly known as CPU. Cpu have many components inside it which are as follows.
Hard Disk:
Hard disk is main storage unit of a computer.
It stores and keeps our data securely and we can find it here at any time. Hard
disk is also known as primary storage device.
DVD Drive:
DVD drive is second compulsory components of a CPU
because it can be used to insert soft data into the computer and further we can
store it in hard disk. DVD can run cd’s and DVDs. These disk drives can store a
limited data and these are known as temporary storage. Because I think data is
not much safer than hard disk. DVD drive is used to run cd’s and DVD to show
data.
RAM:
Ram is also known as random access memory. Ram
is used to show data from computer to display unit. Ram cannot store data but
keeps data for a short time. Without ram system is unable to display any
content.
ROM:
Rom is also known as read only memory which
stores data like bios (basic input output system) and date, time settings. Rom
can store data permanently which can’t be changed anyhow.
These are some parts which are included in a
system CPU discussed above.
Monitor:
Monitor is a display device which shows our
work. Monitor is an output device and computer result is shown on it.
Keyboard:
Keyboard is known as input device which is used
to input data and to input alphabetical and numerical values.
Mouse:
Also an input device which is used to give
orders to computer and it is also known as pointing device.
Printer:
Printer is an output device which is used to
get hard copy result from computer.
Speakers:
Speakers are used to produce sound and to get
sound results from computer system.
Friend’s computer is an amazing invention and
now I want to describe some advantages and disadvantages of computers.
Advantages of computers:
Computer invention has so many advantages which
are described below here.
Computer is used to calculate values in
seconds.
Computer can store hundred of books.
Computer can work even faster than human.
Computer can be used to control robots, cars
and many more.
Computer is used to control factories and store
rooms.
Friends while computer has many advantages for
human beings it also have some disadvantages which are discussed here.
A computer uses energy which costly and poor
countries are unable to afford it.
Computers are costly and everyone can’t afford
it.
Computer is not easy to use for everyone so all
people can’t run it.
Computer has limited man power so its use is
making mankind useless.
Some people are using computer badly and using
it for bad activities which is known as cyber crimes.
Many people don’t known well how to use so they
can’t work efficiently with computers.
Illiterate people are unable to use computer so
they can’t progress in their life.
Dear friend’s computer invention has so many
benefits but it also dropped some negative effects which have sent human being
in trouble.
Some people are using computers with negative
mind which affected our nation.
Guys please use it with positive thinking and
stay blessed.
Have a nice life ahead.
Thanks
