Computer evolution

Although a computer cannot create its own opinions, it can be programmed to do arithmetic and logical tasks. For example, a computer could work out 4309 times 2673 in a second, but it could not answer a question like what do you think we should do about the migrant crisis. Many computer manufacturers hope to, in the future, make computers, or even robots, that can create their own opinion, possibly by looking on the internet when asked a question. Considering how far we have come since the first computers, it looks likely that this will happen.

In the past computers were a lot bigger and chunkier than they are today. The technology of computers in a year such as 1950 was ground breaking at the time, but today we take it for granted. It is not clear who invented the first computers, but there were many people who contributed. Alan Turing was one of the first. He invented a computer during WW2 to crack the German enigma code.

The Difference Engine

The difference engine was the first ever computer. It was invented by Charles Babbage during the 1820's. It was not electrical and instead used cogs and was hand turned. It had no screen and was like a big calculator. It could be told to do mathematical sums, but of coarse, it was a lot slower than a modern computer like a calculator.
