Definition
Your personal computer is a programmable digital camera designed to recognize data, perform prescribed mathematical and logical operations at high speed, and screen the results of these businesses, all under the control of software. Mainframes, desktop and laptops, tablets and smartphones are a few of the several types of computers. An electronic machine which helps in solving problems efficiently. It solves problems regarding to instructions directed at it by the computer individual called programs or software. It is an electronic machine(that uses binary digits) used in all field

Automation
Most humans have trouble with math. To show this, try doing 584 x 3,220 in your mind. It really is hard to remember all the steps! People made tools to help them remember where they were in a mathematics problem. The other problem people have is that they need to do the same problem over and over and once more. A cashier was required to make change every day in her head or with a bit of paper. That took lots of time and made flaws. So, people made calculators that have those same things again and again. This part of computer history is named the "history of robotic calculation," which is a fancy saying for "the history of machines which make it easy for me to do this same maths problem again and again without making flaws."The abacus, the glide rule, the astrolabe and the Antikythera system (which schedules from about 150-100 BC) are types of automated calculation machines.

Programming
People do not need a machine that would do a similar thing over and over again. For example, a music field is a machine that takes on the same music again and again. Some people wanted to be able to notify their machine to do various things. For example, they wished to tell the music package to try out different music every time. They wished to have the ability to program the music pack- to order the music package to play different music. This part of computer record is named the "history of programmable machines" which is a fancy word for "The annals of machines that I could order to do different things if I learn how to speak their terms."Among the first types of this was built by Hero of Alexandria (c. 10-70 AD). He built a mechanised theatre which performed a play enduring ten minutes and was operated by a complicated system of ropes and drums. These ropes and drums were the vocabulary of the machine- they advised what the machine did so when. Some people claim that this is the first programmable machine.Historians disagree on which early on machines are "personal computers". Many say the "castle clock", an astronomical clock invented by Al-Jazari in 1206, is the first known programmable analog computer. The distance of night and day could be changed every day to be able to take into account the changing lengths of night and day over summer and winter. Some count this daily adjustment as computer programming.Others say the first computer was created by Charles Babbage. Ada Lovelace is known as to be the first programmer.

The Computing Era
By the end of the Middle Ages, people in European countries thought math and anatomist were more important. In 1623, Wilhelm Schickard made a mechanical calculator. Other Europeans made more calculators after him. They were not modern computers because they could only add, subtract, and increase- you could not change what they does to make sure they are do something like play Tetris. Because of this, we say these were not programmable. Now technical engineers use computers to design and plan.In 1801, Joseph Marie Jacquard used punched newspaper cards in order to his textile loom what kind of style to weave. He might use punch cards to inform the loom how to proceed, and he could change the punch credit cards, this means he could program the loom to weave the structure he wanted. This means the loom was programmable.Charles Babbage wished to make an identical machine that may analyze. He called it "The Analytical Engine".[8] Because Babbage did not have enough money and always improved his design when he had an improved idea, he never built his Analytical Engine unit.As time continued, personal computers were used more. People get weary easily doing the same thing over and over. Imagine spending your life writng down things on index cards, saving them, and then having to go see them again. The U.S. Census Bureau in 1890 had hundreds of people doing just that. It had been expensive, and studies took a long time. Then an engineer worked out how to make machines execute a lot of the task. Herman Hollerith created a tabulating machine that could automatically accumulate information that the Census bureau accumulated. The Computing Tabulating Recording Company (which later became IBM) made his machines. They leased the machines rather than selling them. Manufacturers of machines experienced long helped their users understand and repair them, and CTR's tech support was especially good.Due to machines such as this, new means of talking to these machines were created, and new types of machines were developed, and finally the computer as we realize it was born.

Analog and Digital Computers
In the first fifty percent of the 20th hundred years, scientists started out using computers, largely because scientists experienced a great deal of math to figure out and wanted to spend more of their time thinking about science questions instead of spending hours adding numbers together. For example, if indeed they had to establish a rocket ship, they had a need to do a whole lot of math to make sure the rocket worked right. So they come up with computers. These analog pcs used analog circuits, which made them very difficult to program. In the 1930s, they developed digital pcs, and soon made them much easier to program. However this is not the case as many consecutive efforts have been designed to bring arithmetic logic to l3.Analogue computer systems are mechanical or gadgets which solve problems. some are used to control machines.
