Definition
Your personal computer is a programmable electronic device designed to recognize data, perform prescribed mathematical and logical operations at broadband, and screen the results of the functions, all under the control of software. Mainframes, desktop and laptop computers, tablets and smartphones are some of different types of computers. An electronic machine which helps in solving problems quickly and easily. It solves problems matching to instructions directed at it by the computer end user called programs or software. It is a digital machine(that uses binary digits) found 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 keep in mind all the steps! People made tools to help them bear in mind where these were in a math problem. The other problem folks have is that they need to do the same problem again and again and once more. A cashier had to make change every day in her head or with a bit of paper. That required a lot of time and made flaws. So, people made calculators that does those same things again and again. This part of computer history is called the "history of robotic 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."The abacus, the slide guideline, the astrolabe and the Antikythera system (which times from about 150-100 BC) are examples of automated computation machines.

Programming
People do not want a machine that could do a similar thing again and again. For example, a music box is a machine that performs the same music over and over again. Some people wanted to have the ability to tell their machine to do different things. For example, they wanted to tell the music pack to experience different music every time. They wanted to have the ability to program the music pack- to order the music box to experience different music. This part of computer history is called the "history of programmable machines" which is a fancy term for "The annals of machines that I can order to do different things if I know how to speak their vocabulary."One of the first examples of this was built by Hero of Alexandria (c. 10-70 AD). He built a mechanical theatre which performed a play prolonged ten minutes and was controlled by a complex system of ropes and drums. These ropes and drums were the terms of the machine- they advised what the device did so when. Some people claim that 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 length of day and night could be adjusted every day to be able to take into account the changing lengths of night and day throughout the year. Some matter this daily modification as computer programming.Others say the first computer was created by Charles Babbage. Ada Lovelace is considered to be the first programmer.

The Computing Era
At the end of the Middle Ages, people in European countries thought mathematics and executive were more important. In 1623, Wilhelm Schickard made a mechanised calculator. Other Europeans made more calculators after him. These were not modern pcs because they could only add, subtract, and multiply- you cannot change what they performed to make them do something like play Tetris. As a result of this, we say they were not programmable. Now technical engineers use computers to create and plan.In 1801, Joseph Marie Jacquard used punched newspaper cards to see his textile loom what kind of design to weave. He could use punch cards to share with the loom how to proceed, and he could change the punch credit cards, which means he could program the loom to weave the structure he wanted. This means the loom was programmable.Charles Babbage wished to make a similar machine that could determine. He called it "The Analytical Engine".[8] Because Babbage did not have enough money and always transformed his design when he had an improved idea, he never built his Analytical Engine unit.As time continued, computers were used more. People get weary easily doing a similar thing again and again. Imagine spending your daily life writng down things on index credit cards, saving them, and then having to go find them again. The U.S. Census Bureau in 1890 had hundreds of folks doing that. It had been expensive, and accounts took quite a while. Then an engineer exercised steps to make machines execute a lot of the task. Herman Hollerith developed a tabulating machine that would automatically accumulate information that the Census bureau gathered. The Processing Tabulating Recording Corporation (which later became IBM) made his machines. They leased the machines rather than selling them. Creators of machines experienced long helped their users understand and repair them, and CTR's technology support was especially good.Due to machines such as this, new means of speaking with these machines were invented, and new types of machines were created, and finally the computer as we realize it was created.

Analog and Digital Computers
In the first half of the 20th hundred years, scientists started using computers, generally because scientists got a lot of math to determine and wanted to spend more of their time thinking about science questions rather than spending hours adding numbers together. For example, if indeed they had to unveiling a rocket dispatch, they needed to do a great deal of math to make sure the rocket functioned right. So they come up with personal computers. These analog pcs used analog circuits, which made them very hard to program. In the 1930s, they developed digital computers, and soon made them better to program. Financial firms not the case as much consecutive attempts have been designed to bring arithmetic logic to l3.Analogue computer systems are mechanised or electronic devices which solve problems. some are used to control machines.
