what is a motherboard? role/importance?
- "nervous system"
- piece of technology where all other components plug in or connect
- allows power to be distributed to all other components
- allows for communication between components (a) commands, (b) data
computer as a job title
- a person or people who would solve math problem/equations for scientists, military, sailors/naval, architects/engineers
- check their work against other "computers", and repeat calculation if a mistake found
basic input output system (BIOS)
- located in ROM chip on the motherboard
- a PROGRAM that allows key components to operate (monitor, keyboard, mouse, date/time, storage/HDD)
- loads OS from the hard drive
cache RAM
- fastest, smallest
- on microprocessor
- holds data on current operation or calculation
- volatile, data lost when power off
system RAM
- fast, small
- stores data of all running programs
- volatile, data lost when power off
hard drive
- slow, large
- store all data on computer
- non-volatile, data is saved even when power is off
microprocessor
- "brains"
- controls most activity on computer (sends out commands)
- performs calculations (CPU)
- CPU, cache ram
