processing. located closer to CPU than the RAM


cache memory - High speed memory that enables the computer to temporarily store
blocks of data that are used more frequently


random access memory (RAM) - holds a software program and small amounts of data
for processing


read only memory (ROM) - type of chip where certain critical instructions are held and
retains these instructions even when the computer is off MANUFACTURER INSTALLS
THIS
Types of secondary storage - correct answers-Magnetic tape - on a large open reel or in
a smaller cartridge or cassette

, magnetic discs - most widely used


solid state drives (SSD) - serve the same purpose as a hard drive and store data in
