Answer 1

RAM

Question 2

non-volatile memory used for storing permanent data or instructions. It retains its content even when the power is off and is typically used for essential system instructions, is known as?

Answer 2

ROM

Question 3

There are levels of memory, with smaller units being more performant. Can you name the different types?

Answer 3

• registers
• cache
• ram
• hard disk

Question 4

True or False - caching is only done at smaller memory hierarchy levels to improve performance of recently used data?

Answer 4

True

Question 5

How is data stored on a 64 bit computer?

Answer 5

Data is stored at unique memory addresses in bytes. The max storage at these addresses is equal to the architecture of the system

Question 6

What is memory access time? And what might affect it?

Answer 6

• the time it takes the cpu to retrieve data from the specified memory location
• the hierarchy of the data .i.e data closer to the cpu has faster access times
