Designed for fast processing, mass storage, still used today. Microprocessor incorporated central processing unit (cpu) short-term memory in integrated circuits (ics) Technology keeps advancing, moore"s law cheap access to high quality resources. Value of info tech measured in power of network that can be accessed with machine. Consists of electronic components that input, process, output, store data. Cpu, main memory, buses, ports, etc. are connected here. Selects instructions, processes data, performs comparisons, store results of operation in memory. Memory swapping loading memory in chunks when needed, and swapping with unneeded stuff. Cpu transfer program/data from disk to main memory. Move instruction from main memory to cpu via data channel/bus. Fast memory, cache frequently used instructions kept here a. Large collection of computers that coordinate all activities.
