Document Summary

Microchips: store and process data in electronic devices. Microprocessors: the miniaturized circuitry of an entire computer processor on a single chip. Contain the central processing unit (cpu), which processes data into information: system unit : the case that contains the computer"s electronic components used to process data. Pcs: tower or desktop; monitor is separated. Laptops: monitor is attached to the system unit, like a clamshell. Bit: each 0 or 1 is a bit. Byte: a group of 8 bits = 1 character, digit, or other value. Exabyte (eb) 1 quintillion bytes: binary code schemes assign a unique binary code to each character, unicode : (16 bits/character). handles 65536 characters (used for chinese and. Japanese: ebcdic (extend binary coded decimal interchange code) Used for ibm mainframes: machine language. A binary-type programming language (0s and 1s) built into the cpu that is run directly by the computer. Each cpu type has its own language => each machine language is brand- dependent.
