primary storege
secondary storage
non-volatle storage (permanently)
not under control -> cpu
/ directly interact whit apllications
type of //
hard drive disk
most common type -> magentic storage
used: storing/retraiving data
consist of 1/+ rigid rapidly rotating discs (platters) --> write data on (surfaces)
external storage drives
used -> storage (programs/data) -> not neded immediatly
area -> computer in witch data/ applications (temporarly) --> saved while pc is running
very fast, expensive, small in size/capacity - direct acess to cpu
include
cpu register
small amount of storage aspart of digital processor
cache
high speed ram that holds most frequentlt informations/commands --> speed up access to files/operarions
ram
temporary memor -> attached to thr motherboard of system bus. loses it's content ->power of
influences-> the processing power of computer/ the speed and number (programs) the computer can run at the same time
Rom
permanent memory -> designed by manufacturer and put data/programs neccesary to make computer work
memory
anyphysical device capable of storing data/applications
permanently
non volatle
loses --> data -> when -> computer (off)
temporarly
volatle
it keeps -> data even -> if (power off)
different type (memory) --> classified according (memory hierarchy)
levels -> it depends on: speed/ latency
highest level -> fastest/lownest latency
primary storage
secondary storage
mdirect access (cpu) -> slow/chap/large in size
tertiary storage
indirect access (cpu)-> very slow/chap/very large in size
