Essay on Computers Words Article shared by: Read this comprehensive essay on Computers! Basically, computer is a device that accepts the message by the imputer and processes this message and stores the information at the storage devices and later gives an output of the message through the output devices.
History of computers[ change change source ] The Jacquard loom was one of the first programmable devices. Definition[ change change source ] A computer is a programmable electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations, all under the control of software.
Mainframes, desktop and laptop computers, tablets and smartphones are some of the different types of computers. An electronic machine which helps in solving problems quickly and easily.
It solves problems according to instructions given to it by the computer user called programs or software. It is a digital machine that uses binary digits used in all fields. Automation[ change change source ] Most humans have a problem with math.
It is hard to remember all the steps! People made tools to help them remember where they were in a maths problem. Essay about uses of computers other problem people have is that they have to do the same problem over and over and over again. A cashier had to make change every day in her head or with a piece of paper.
That took a lot of time and made mistakes. So, people made calculators that did those same things over and over. This part of computer history is called the "history of automated calculation," which is a fancy phrase for "the history of machines that make it easy for me to do this same maths problem over and over without making mistakes.
Computer programming People did not want a machine that would do the same thing over and over again. For example, a music box is a machine that plays the same music over and over again. Some people wanted to be able to tell their machine to do different things.
For example, they wanted to tell the music box to play different music every time. They wanted to be able to program the music box- to order the music box to play different music.
This part of computer history is called the "history of programmable machines" which is a fancy phrase for "The history of machines that I can order to do different things if I know how to speak their language.
He built a mechanical theater which performed a play lasting 10 minutes and was operated by a complex system of ropes and drums. These ropes and drums were the language of the machine- they told what the machine did and when.
Some people argue that this is the first programmable machine. Many say the "castle clock", an astronomical clock invented by Al-Jazari inis the first known programmable analog computer.
The Computing Era[ change change source ] At the end of the Middle Agespeople in Europe thought math and engineering were more important. InWilhelm Schickard made a mechanical calculator. Other Europeans made more calculators after him. They were not modern computers because they could only add, subtract, and multiply- you could not change what they did to make them do something like play Tetris.
Because of this, we say they were not programmable. Now engineers use computers to design and plan. InJoseph Marie Jacquard used punched paper cards to tell his textile loom what kind of pattern to weave.
He could use punch cards to tell the loom what to do, and he could change the punch cards, which means he could program the loom to weave the pattern he wanted.
This means the loom was programmable. Charles Babbage wanted to make a similar machine that could calculate. He called it "The Analytical Engine". As time went on, computers were used more. People get bored easily doing the same thing over and over. Imagine spending your life writing things down on index cards, storing them, and then having to go find them again.Uses of Computer in Field of Business Computer in business: Information Technology (IT) has played a very significant role in taking business to new height.
Before computers, the time taken to complete a task was more and however as computer started to be used in business establishments, the processing of work got more stabilized. Jul 28, · This essay includes all the information you needed to know about the computers, such as the invention, origin, history of the computer, the uses of the computer and the advantages or benefits and disadvantages of the computers/5(2).
Both laptops and desktops are called personal computers, because one person at a time uses them for things like playing music, surfing the web, or playing video games. There are bigger computers that many people at a time can use.
These are called "Mainframes," and these computers do all the things that make things like the internet work.
