system unit
a case that contains electronic components of the computer used to process data
motherboard
main circut board of the system unit
chip
small piece od semiconducting material usually silicon, on which integrated circuts are used.
CPU
interprets and carries out the basic instructions that operate a computer
multi core processor
a chip with two or more separate processor cores
control unit
component of the processor that directs and coordinates most of the operations
ALU
performs arithmetic comparison and other operations. component of the processor
system clock
small quartz crystal circut. comtols timing of computer
clock speed
measured by number of ticks per second in the gigahertz range
binary system
number system that has just two unique digets, 0 and 1
bit
smallest unit of data a computer can process
byte
8 bitd grouped together as a unit. can represent up to 256 characters
memory
electronic components that store instructions waiting to be carried out by the processor
volatile memory
type of memory in which when the computer is turned off its content is lost forever
non volatile memoey
memory in which when the computer is turned off the data is stored.
RAM memory
memory chips that can be read from and written to by the processor and other devices
ROM memory
memory chips storing permanent data and instructions. cannot be modified
memory module
RAM chips reside on them. samll circut board
memory slot
on the motherboard. holds memory modules
catche
helps speed up thr process of the computer bc it stores frequrntly used data and instructions
L1 catche
built directly into the processor chip, usually has a very small capacity range from 8-128 kb
L2 catche
slightly slowr then l1, has a larger capacity range of 64-16 MB
ROM
memory chips permanent data and instructions. cant be modified
Flash memory
type of nonvolatile memory that can be erased and re-written.
