Is a mechanical device for applying pressure to an inked surface resting upon a medium (such as paper or cloth), thereby transferring an image. The mechanical systems involved were first assembled in Germany by the goldsmith Johannes Gutenberg around 1440, based on existing screw-presses used to press cloth, grapes, etc. and possibly prints.Gutenberg was the first in Western Europe to develop a printing press.

Computers are commonly used items in many areas. It is an important thing to people, especially the people who run organizations, industry.Almost anything you know is run or made by computers. Cars and jets were designed on computers, traffic signals are run by computers, most medical equipment use computers and space exploration was started with computers. Most of the jobs today require the use of computers. These 'mechanical brains' made a huge impact on our society. It would be hard if we didn't have the computer around. People in the medical field wouldn't have have found a lot of cures to diseases, since most cures were found with the help of computers. Movies like Jurassic Park, Toy Story, A Bug's Life or Godzilla would never have been made without computers because they used computer graphics and animation in them. Pharmacies would have a hard time keeping track with what medications to give to patience. Counting votes would be impossible without computers and most importantly, space exploration wouldn't be possible without the help of computers. It's a pretty tough life without computers. Some may not agree and say, "Well, we don't need computers to live on." They maybe right but mostly, they are wrong. Computers help in curing diseases, make entertainment a lot better, keep track of important records, etc. . . Without computers, all this wouldn't be possible.
