16 Questions
What is the main function of memory in a computer system?
To store and retrieve digital data or programs
Which type of memory retains its contents even when the machine is switched off?
Read Only Memory (ROM)
What is the main difference between EPROM and EEPROM?
EPROM can be erased electronically, while EEPROM uses UV radiation for erasing
What characteristic distinguishes Dynamic RAM(DRAM) from other types of RAM?
It requires constant refreshing to retain data
How is Programmable ROM (PROM) different from Erasable Programmable ROM (EPROM)?
Once programmed, PROM data cannot be changed, while EPROM data can be erased and reprogrammed
In what way does Random Access Memory (RAM) differ from Read Only Memory (ROM)?
RAM loses its contents when the machine is switched off, while ROM retains its contents
Which type of RAM is more complex than DRAM and maintains its cell output until altered to a new value or the power is turned off?
Static RAM(SRAM)
Which type of RAM theoretically could transfer data on the rising and falling edges of the system clock?
Double Data Rate SDRAM(DDR SDRAM)
What type of memory management capability allows a computer to compensate for physical memory shortages by temporarily transferring data from RAM to disk storage?
Virtual Memory
Which type of memory sits between external memory and the processor, running at speeds closer to the processor?
Cache Memory
Which part of the CPU is used to store data temporarily during program execution?
Registers
Which type of memory is faster to access than main memory but has a slower access time than registers?
Cache Memory
What type of memory system is constructed in a Hierarchy, with faster memory being higher in the hierarchy?
Memory Hierarchies
What is the main goal of a memory hierarchy?
To keep the data that is accessed most high up in the hierarchy
What type of RAM is used in both main memory and video cards?
Extended Data Output RAM(EDO RAM)
What type of RAM uses hardware and software to allow a computer to compensate for physical memory shortages?
Virtual Memory
