Laptops desktops and personal digital assistant P D

Laptops, desktops and personal digital assistant (P. D. A. ), are modern technologies that first appeared as luxuries but have developed into necessities. Nowadays almost everyone has a desktop , laptop or P. D. A. ; they are seen in schools, businesses, offices and homes. These technological advances help people to research as well as communicate throughout their busy day. Twenty years ago the thought of a computer allowing people to communicate would sound ridiculous. Twenty years ago the though of someone carrying a person digital assistant the size of his palm sounded impossible. But the pioneers of technology have made this a reality.

Go back 50 years ago and you won’t see any hi-tech computers. There won’t be any 3 pound laptops and there definitely won’t be any palm sized personal digital assistance, or “P. D. A. s” When the first computer was introduced it was a large chunk of metal and plastic. It did not have internet access or graphics. Just like the computer, the laptops were larger, slower and not very colorful. The first laptop was used by NASA to go into space. The original P. D. A. was used strictly for a personal organizer. It helped businessmen keep tabs on all their appointments.

The first successful laptop was created 1979 by William Moggridge for the Grid Systems Corporation. But this was used by Nasa in space and many don’t believe it to be an actual laptop. In May of 1983 Manny Fernandez created his version of the laptop. The main purpose of the laptop was not to send it into space but for executives that are always on the go. This new computer could rest on the lap of the busy executive while he sits on the train, on the couch or even on the plane. Now executives can leave the office without leaving their work behind. This was called the Gallivan Computer and many considered it to be the first successful laptop. In addition to Fernandez’s computer, Bill Gates and Kazuhiko Nishi were coming up with the idea for a portable computer. After creating the “new computer” they presented it to Radio Shack who later produced the flat, four pound , portable computer.

Desktops have been around longer than laptops and P. D. A. s. Desktops first came out in the 1970 s and the 1980 s. When they were first invented they looked nothing like they look now. They were large chunky pieces of metal and plastic and were definitely not as fast as they are now. Again, Apple was among the first to come out with a sufficient computer, called the Apple II. This came out in 1977 and has been evolving ever since then.

The computers of the future are completely different from the computers we use today. With the help of bluetooth technology the computer will be the size of a pen with two holes on either sides. Through the holes will come a hologram-like kepyboard and what would appear on the monitor.
