a world-wide network of computer systems that allows for the exchange of electronic mail, public messages, data, and files
Internet
the units (which means millions per second) used to measure clock speeds of computers

an intergrated circuit that imcludes all of the main functions of a computer over the telephone
microprocessor
a device that allows inteaction to occur between computers over the telephone
modem
a computer's main circuit board
motherboard
a group of computers that are connected by a communications link that allows them to share data or hardware resources
network
data or info provided by a computer to a user
output
a computer's random-access memome (RAM)
primary storage
a computer's primary storage;is where currently running programs and active data are stored
random-access memory
(RAM)
a set of memory chips that have instructions and data permantly stored upon them
read-only memory (ROM)
a microprocessor that accepts a relatively small number of instructions, each of which perform simple operations. the PowerPC is an example
reduced instruction set computer (RISC)
a memory circuit that holds data that is being manipulated by the execution unit of the microprocessor
registers
a form of data storage more permanent than RAM, usually magnetic disk media
secondary storage
a set of programs in the ROM of MAC computers
toolbox
in terms of memory, RAM is called this because it can be lost if power to the computer is interrupted
volatile
