What is a computer?
an electronic device which is capable of receiving information (data) in a particular form and of performing a sequence of operations in accordance with a predetermined but variable set of procedural instructions (program) to produce a result in the form of information or signals. A person who makes calculations, especially with a calculating machine.




computer model
Babbage- A mathematician, philosopher, inventor and mechanical engineer, Babbage is best remembered for originating the idea of a programmable computer. Parts of Babbage's unfinished mechanisms are on display in the London Science Museum. In 1991, a perfectly working change engine was made from Babbage's original plans. Built to tolerances achievable in the 19th century, the success of the finished engine showed that Babbage's device would have worked. 

 WW2 Colossus
Colossus was the first large-scale electronic computer, it was used against the German system of teleprinter encryption know at Bletchley Park as ‘Tunny’. Tunny, carried the highest grade of cleverness, from 1941 Hitler trusted on Tunny to protect their communications with Army Group leaders across Europe. Colossus was used to break their codes down, so it was a codebreaker. Colossus was made by the engineer Tommy Flowers to solve a problem posed by mathematician Max Newman.



Post war Leo -early electronics
In 1951 the Leo I computer was working and ran the world's first regular routine office computer job. The company Leo Computers Ltd was formed in 1954. Leo II computers were installed in many British offices, including Ford Motor Company, British Oxygen Company and the 'clerical factory' of the Ministry of Pensions at Newcastle.


1980’s – PC
Home computing shown to be so common, the 1980s were the main times of the pc, all companies wanted to release their own. In 1984 we saw the real ‘computer’ that we use these days, the Apple Macintosh. The Macintosh completely changed how computer were seen in those days, it had a gui. The average Joe could go and buy one, come home and it would be so simple, no lines of code or anything! The GUI was thought to be quite accountable for our modern computers, the windows computers didn’t have a GUI until 1996. Most company’s wanted a slice of the digital pie, with model after model released on a yearly basis.

5th generation computer devices, constructed on artificial cleverness, remain still in progress, nevertheless there are some requests, such as talking recognition, that are being used today. Ever since 1984, the pc is evolving in ways, in which to a level can save live. We carry computers around in our pockets such’s phones, tablets and iPods etc.
