What are the Objectives, Characteristics and Scope of Management Information System

Definition
A pc is a programmable digital camera designed to agree to data, perform prescribed mathematical and logical operations at high speed, and screen the results of the businesses, all under the control of software. Mainframes, desktop and laptops, tablets and smartphones are some of different types of computers. An electronic machine which assists with solving problems quickly and easily. It solves problems matching to instructions given to it by the computer customer called programs or software. It really is an electronic machine(that uses binary digits) used in all field

Automation
Most humans have a problem with math. Showing this, try doing 584 x 3,220 in your mind. It is hard to remember all the steps! People made tools to help them bear in mind where these 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 were required to make change every day in her head or with a bit of paper. That required a lot of time and made problems. So, people made calculators that do those same things over and over. This part of computer history is named the "history of robotic calculation," which really is a fancy expression for "the history of machines which make it possible for me to get this done same maths problem over and over without making mistakes."The abacus, the slip guideline, the astrolabe and the Antikythera mechanism (which schedules 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 field is a machine that takes on the same music over and over again. Some people wished to have the ability to inform their machine to do different things. For instance, they wished to notify the music pack that can be played different music every time. They wanted to have the ability to program the music container- to order the music container to experiment with different music. This part of computer history is named the "history of programmable machines" which is a fancy saying for "The annals of machines that I can order to do various things if I learn how to speak their dialect."Among the first examples of this is built by Hero of Alexandria (c. 10-70 Advertising). He built a mechanical theater which performed a play enduring 10 minutes and was run by a sophisticated system of ropes and drums. These ropes and drums were the terms of the machine- they informed what the device did and when. Some people dispute that is the first programmable machine.Historians disagree on which early on machines are "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 altered every day in order to take into account the changing lengths of night and day over summer and winter. Some matter this daily modification as education.Others say the first computer was created by Charles Babbage. Ada Lovelace is considered to be the first programmer.

The Processing Era
At the end of the center Age ranges, people in European countries thought math and executive 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 multiply- you could not change what they does to make sure they are do something like play Tetris. As a result of this, we say these were not programmable. Now designers use computers to design and plan.In 1801, Joseph Marie Jacquard used punched newspaper cards to share his textile loom the type of pattern to weave. He could use punch cards to share the loom how to proceed, and he could change the punch credit cards, which means he could program the loom to weave the style he wanted. This implies the loom was programmable.Charles Babbage wished to make an identical machine that can assess. He called it "The Analytical Engine".[8] Because Babbage did not can pay for and always changed his design when he had a better idea, he never built his Analytical Engine.As time continued, personal computers were used more. People get bored stiff easily doing a similar thing over and over. Imagine spending your daily life writng down things on index credit cards, holding them, and then having to go find them again. The U.S. Census Bureau in 1890 had hundreds of men and women doing just that. It had been expensive, and reviews took a long time. Then an engineer worked out how to make machines do a lot of the task. Herman Hollerith created a tabulating machine that could automatically add up information that the Census bureau collected. The Processing Tabulating Recording Company (which later became IBM) made his machines. They leased the machines rather than selling them. Producers of machines got long helped their users understand and repair them, and CTR's technical support was especially good.Because of machines such as this, new ways of talking to these machines were invented, and new types of machines were created, and eventually the computer as we know it was created.

Analog and Digital Computers
Inside the first fifty percent of the 20th century, scientists started using computers, typically because scientists experienced a great deal of math to figure out and wanted to spend more of their own time thinking about knowledge questions instead of spending hours adding numbers mutually. For example, if indeed they had to establish a rocket ship, they needed to do a whole lot of math to make certain the rocket worked well right. So they come up with pcs. These analog personal computers used analog circuits, which made them very difficult to program. In the 1930s, they created digital personal 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 personal computers are mechanised or gadgets which solve problems. some are being used to control machines.
