Memory Flashcards
What are the two relevant forms of memory?
RAM and ROM.
How does ROM work?
Read-Only Memory.
This stores a series of basic operation instructions such as booting the computer and loading the operate system.
It is non-volatile hence it is not wiped when the computer is truned off.
How does RAM work?
Random Access Memory.
This temporarily stores data being accessed and utilised by the CPU. Increasing RAM increases the memory capacity, allowing fro computers to hold and process more data.
This form of data is volatile, meaning it gets wiped when the omputer is powered off.
What are the types of ROM?
ROM.
PROM.
EPROM.
EEPROM.
Which form of ROM chip is typically used for the systems BIOS?
EEPROM.
Which forms of ROM can be reprogrammed?
EPROM.
EEPROM.
Which form of ROM can either not be reprogrammed, or only programmed once?
ROM.
PROM.
What are the types of RAM?
Dynamic RAM. Static RAM. SDRAM. DDR SDRAM. DDR2 SDRAM. DDR3 SDRAM. DDR4 SDRAM GDDR SDRAM.
What is the SDRAM family?
SDRAM is a family of RAM specifications that transfers data twice as fast as the previous specification.
They twypically have an increasing amount of pins and lowering amount of voltage/power.
What are memory modules?
Memory modules are memory chipcs that have been soldered to a circuit board that are comptable with the memory slots on a motherboard.
This saves on having to have RAM installed as individual chips.
What are the different forms of memory modules?
DIP.
SIMM.
DIMM.
SODIMM.
What is typically the fastest form of memory?
SRAM.
Static RAM.
What family of RAM does DIMM cover?
SDRAM.
What is SODIMM?
SODIMM is a mroe compressed form of DIMM. It is ideal for usage within laptops, printers and other devices where conserving space is desirable.
What are the three forms of Cache Memory?
L1.
L2.
L3.
