Random Access Memory (RAM) is used to store the programs and data being used by the CPU in real-time.
True
False
The data on the random access memory can be read, written, and erased only ONE time.
True
False
Ram is a volatile (temporary) memory.
True
False
Read-Only Memory (ROM) is a type of memory where the data has been prerecorded.
True
False
Data stored in ROM is lost even after the computer is turned off.
True
False
ROM is a non-volatile (permanent) memory.
True
False
There are THREE types of RAM.
True
False
In DRAM, data is stored in capacitors.
True
False

True
False
DRAM is called dynamic as constant change or refreshing is needed to keep the data intact.
True
False
DRAM is used to implement main memory.
True
False
In SRAM, data is stored in
Transistors
Capacitors
SRAM requires a constant power flow to store data.
True
False
SRAM is cheaper than DRAM.
True
False
SRAM doesn’t need to be refreshed periodically.
True
False
SRAM is called static as no change or no refreshing is needed to keep the data intact.
True
False
DRAM is faster than SRAM.
True
False
SRAM is used in cache memories.
True
False
