Computers today!

There have been many computers that have been made throught the years like the Z3, ENIAC, and the Difference engine. Today the technology is harder to figure out, but also easy in some ways.With computers today you can talk to someone with over email or you can go on Skype and do a video chat, but computers long ago you could not do that. There are many different computers that are comming out now, like the iPad the Mac, and many others to come.

Z3

The Z3 is the first computer that is fully program controlled in the entire world. The Z3 computer was built in 1941 by Konrad Zuse he was a very smart German engineer. It took Konrad Zuse from 1938 to 1941 to design and build it. In 1943 the Z3 was destroyed by a bombing raid of berlin. In the later 1960's he decided to supervise a reconstruction of it.

conclusion

There have been many different computers that were made before now. People say the ENIAC was the first computer ever made, and people say the Difference Engine was the first computer ever made, but no one acctually knows who made the first computer. Technology in the world today is getting more and more difficult. Computers like the ENIAC and the Z3 are not going to be made anymore because people want something new. Even though computers are being changed every second without the people who invented them a long time ago, we would not have computers.

The ENIAC

The ENIAC is said to be the first digital computer. The ENIAC was invented by two people named Jonh Mauchly and J. Presper Eckert. The accronym ENIAC stands for "Electronic Nuemerical Integrator and Computer". They began making it in 1943 and ended in 1946, and the place where they made it was the University of Pennsylvania. The ENIAC is very large as you can see in the picture, and is weighed about 50 tons.

Difference Engine No. 2

People say the Difference Engine is the first computer ever made. The person who improved it was Charles Babbage, he is known as "The father of the computer". How you use the computer you have to crank a handel that is how it is powered, it uses the decimal numbers system. The British government did not support it so they did not support him anymore. In 1834 through 1869 he improved the Difference engine and called is Difference Engine No. 2. People say that it was the first electronic computer ever made.

The Abacus

The Abacus was the first calculating system. The Abacus and was invented by the Chinese, it is not exactly a computer, but the ideas of the calculator came from the Abacus. People who made the computers that are in the world today, got the idea of putting a calculator in the computers from the Abacus.
