8 Characteristics of Good Management Information Systems – Explained!

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

Automation
Most humans have a problem 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 they were in a math problem. The other problem people 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 mind or with a piece of paper. That had taken lots of time and made errors. So, people made calculators that did those same things over and over. This part of computer background is called the "history of robotic calculation," which really is a fancy phrase for "the history of machines that make it easy for me to get this done same maths problem over and over without making blunders."The abacus, the glide rule, the astrolabe and the Antikythera mechanism (which dates from about 150-100 BC) are types of automated computation machines.

Programming
People do not want a machine that would do the same thing again and again. For example, a music container is a machine that takes on the same music over and over again. Some people wished to be able to inform their machine to do different things. For example, they wanted to tell the music container that can be played different music every time. They wanted to have the ability to program the music container- to order the music package to experiment with different music. This part of computer record is called the "history of programmable machines" which is a fancy key phrase for "The annals of machines that I can 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 Advertisement). He built a mechanised theatre which performed a play prolonged 10 minutes and was controlled by a complicated system of ropes and drums. These ropes and drums were the terminology of the machine- they told what the device did and when. Some people dispute that this is the first programmable machine.Historians disagree on which early machines are "computer systems". Many say the "castle clock", an astronomical clock invented by Al-Jazari in 1206, is the first known programmable analog computer. The distance of day and night could be changed every day to be able to take into account the changing measures of day and night throughout the year. Some count number this daily modification as computer programming.Others say the first computer was made by Charles Babbage. Ada Lovelace is known as to be the first programmer.

The Processing Era
By the end of the Middle Age range, people in European countries thought mathematics and engineering were more important. In 1623, Wilhelm Schickard made a mechanised calculator. Other Europeans made more calculators after him. They were not modern personal computers because they could only add, subtract, and multiply- you cannot change what they performed to make them do something like play Tetris. Because of this, we say these were not programmable. Now technical engineers use computers to create and plan.In 1801, Joseph Marie Jacquard used punched paper cards to inform his textile loom the type of pattern to weave. He could use punch cards to see the loom how to proceed, and he could change the punch cards, this means he could program the loom to weave the design he wanted. This means the loom was programmable.Charles Babbage wanted to make a similar machine that could compute. He called it "The Analytical Engine".[8] Because Babbage did not have enough money and always modified his design when he previously a better idea, he never built his Analytical Engine motor.As time continued, pcs were used more. People get tired 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 individuals doing just that. It was expensive, and accounts took quite a while. Then an engineer exercised steps to make machines execute a lot of the task. Herman Hollerith created a tabulating machine that would automatically accumulate information that the Census bureau accumulated. The Computing Tabulating Recording Corporation (which later became IBM) made his machines. They leased the machines instead of selling them. Makers of machines had 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 developed, and new types of machines were developed, and finally the computer as we know it was created.

Analog and Digital Computers
In the first one half of the 20th hundred years, scientists began using computers, usually because scientists had a whole lot of math to figure out and wanted to spend more of their time thinking about knowledge questions instead of expending hours adding numbers along. For example, if they had to establish a rocket dispatch, they needed to do a lot of math to make certain the rocket functioned right. So they come up with pcs. These analog computers used analog circuits, which made them very difficult to program. In the 1930s, they developed digital computers, and soon made them better to program. Financial firms false as many consecutive makes an attempt have been made to bring arithmetic reasoning to l3.Analogue computer systems are mechanised or electronic devices which solve problems. some are used to regulate machines.
