Uncategorized 50 Best Movies for Middle School We recently decided to show a movie to our 6th, 7th and 8th grade students on the last day of school.
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 math problem. The 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 do 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.
Census Bureau in had hundreds of people doing just that. It was expensive, and reports took a long time. Then an engineer worked out how to make machines do a lot of the work.
Herman Hollerith invented a tabulating machine that would automatically add up information that the Census bureau collected.Die Barhufbewegung ist weit gekommen. Kompetente Hufbearbeiter auf der ganzen Welt haben die Rehabilitation von chronischer Hufrehe und Strahlbeinerkrankungen zum Tagesgeschäft gemacht und immer mehr Hufschmiede und Tierärzte nehmen davon Notiz und folgen ihrer Anleitung.
The Macintosh (pronounced as / ˈ m æ k ɪ n ˌ t ɒ ʃ / MAK-in-tosh; branded as Mac since ) is a family of personal computers designed, manufactured, and sold by Apple Inc.
since January The original Macintosh was the first mass-market personal computer that featured a graphical user interface, built-in screen and mouse. Apple sold the Macintosh alongside its popular Apple II.
Aryan Invasion Theory (AIT), which today having been rechristened as Indo – Aryan Migration (IAM) theory (given that the original position is no longer tenable) is the largest myth that was ever propagated by historians with vested interests that still retain vestiges to their Western paymasters.
