Semiconductor
Definition: A material that is neither a good conductor of electricity (like copper) nor a good insulator (like rubber). The most common semiconductor materials are silicon and germanium. These materials are then doped to create an excess or lack of electrons. Computer chips, both for CPU and memory, are composed of semiconductor materials. Semiconductors make it possible to miniaturize electronic components, such as transistors. ...

Microprocessor The silicon chip with thousands of electronic components that serves as the central processing unit (CPU) in microcomputers. Ted Hoff www.ideafinder.com/history/inventions/microprocessor.htm 1968 www.ideafinder.com/history/inventions/microprocessor.htm Circuit Board A thin board, usually fiberglass, on which components are mounted. Also called a printed circuit board (or PCB) because the connections between the components are printed onto the board.

Guglielmo Marconi http://inventors.about.com/od/rstartinventions/a/radio.htm 1895 http://inventors.about.com/od/rstartinventions/a/radio.htmBluetuse Bluetooth is a computing and telecommunications industry specification that describes how mobile phones, computers and PDAs can easily interconnect with each other and with home and business phones and computers using a short wireless connection. Ericsson http://www.answers.com/bluetooth 1998 http://www.answers.com/bluetoothTelevision System that converts both audio and visual information into corresponding electrical signals which are then transmitted through wires or by radio waves to a receiver which reproduces the original information.

Digital computer representations can be broken down to simple binary expressions. All modern computers are digital as opposed to analog computers which would express values as individual points on a continuum. A slide-rule would be an analog computer. George Stibitz inventors.about.com/library/inventors/blstibitz.htm 1939 inventors.about.com/library/inventors/blstibitz.htmCD Rom CD ROM stands for Compact Disk Read-Only Memory. CD ROMs store and read massive amounts of information on a removable disk platter or solid state storage chip. Unlike the data on hard drives and diskettes, data on CD ROMs can only be read--not altered--by the user. Also called "firmware." 1984 http://inventors.about.com/library/weekly/aa010500a.htmDVD "Digital Versatile Disk." (Formerly Digital Video Disk.) Same size as a CD but stores seven times CD capacity on a single side. DVDs can also be double-sided or dual layer. Today most DVDs are used to display full-length commercial motion pictures, plus additional material such as outtakes, director's notes, movie trailers, etc.
