Quiz: RAM and Memory Technologies

The primary function of RAM in a computer is to (a)  

• Store permanent data
• Provide temporary storage for runni
• Improve CPU processing speed
• Manage power supply to components

RAM is considered volatile memory because it (a)   when power is lost.

• A) It stores data permanently
• B) It loses all data when power is
• C) It uses more power than other me
• D) It operates at a slower speed

Which type of RAM is faster but more expensive?

• DRAM

• Flash Memory

• SRAM

• DDR4

What is the role of DRAM in a computer?

• Store data permanently

• Maintain data without refreshing

• Provide main system memory

• Control data flow to peripherals

How often must DRAM be refreshed to retain data?

• Once every second
