Introduction to Computer

Computers are the machines that can perform tasks or calculations according to set of instructions or programs. The term computer is derived from the word compute which means to calculate. Computer is an electronic device that can perform arithmetic and logical calculations faster. The first fully electronic computers, introduced in 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today's computers are not only thousand times faster, they can fit on your desk, lap and even pocket. You must appreciate the impact of computer in our day-to-day life. The computer has been useful in reservation of tickets in Airlines and Railways, payment of telephone and electricity bills, deposits etc.

Advantages of computer

Computers are very fast due to which thousands of job can be performed within a short period of time.

Complex mathematical problems and logical operations can be solved by using this computer.

As computer is a versatile device, multiple task like communication, graphics, documentation can be done.

A huge amount of data can be stored and retrieved as it has high storage capacity.

Disadvantages of computer

Computers are machine hence, they have no brain so they work according to the program instructions set inside it.

It is an electronic device and it uses electrical sources to work, so it is very risky to store data and information on the computer independently because some electrical and electronic damages may damage the data. So we have to make regular backup of the data.

Since computers are very expensive device, it becomes beyond the capacity of general user. But now a day its price is going down than past.

Computers require dustless and temperature maintained environment for best performance

Write a story, a tale, a biography or a diary.

I will write a very short story, so I hope this helps a little

The processing of gold: A diary entry

April 5/2018

I am the worlds most precious metal. 
I am worth more than any silly diamond, and far more stronger than Iron. No one can come close to being as important as I.

I start as a tiny mineral, found underground where I spend my days perfecting myself. Most might find relatives of mine in water, buried among sand and dirt. Then we are put through the most rigorous of training until we are god.

Well, gold, but you know what I mean.

Once I am perfection, I will be sold among the masses of people.   I will be loved my all and crafted into everything. If I wanted, I could take over the world...a world of just gold, wouldn't that be magical?

Today I think I will be made into a ring, I hope I am not squeezed on some fat woman's finger.

I hope this helps a little, Cheers :)
