Document Summary

Unit 1: using technology to change the world. It: techniques for info handling, retrieving, computers, telecommunicaions. Data mining: searching data, ind patern, target demographic. Generaive design: create using rules or algorithms. Computer forensics: analyzing systems to gather legal evidence. Afecive compuing: systems can recognize human emoions (e. g. mach) Bit = zero or one in binary language. 8 bits = 1 byte (256 possible combos that they are in) Input data w/ keyboard, digital camera, webcam, mic. Output data w/ monitors (lcd, led, crt), printers (inkjet, laser) Motherboard: circuit board, holds cpu, ram, expansion cards & built-in components. Hard drive common way to store data. Ram (random access memory) is non-permanent memory, stores current data, rom (read-only memory) stores startup instrucions, permanent memory. Cpu: central processing unit controls all funcions, perform a large # of tasks/sec, processor speeds are measured in gigahertz (ghz) Drive bays: hold components e. g. hard drives, cd and dvd drives.
