Topic 6: RAM (Random Access Memory)

Which of the below does not describe RAM?

• Main memory

• Primary memory

• Temporary storage

• Permanent storage

RAM stands for

• Random Access Memory

• Reliability, Availability, and Maintainability

• Remote Access Memory

• Random Access Machine

In order for a program to run, it needs to be loaded into...

• ROM

• CPU

• RAM

• SSD

If the memory is low, which of the following is not likely to happen?

• It might not hold all of the data the cpu needs.

• Part of the data is kept in the hard drive to compensate low memory.

• Computer slows down.

• Computer works normal.

What do you expect a computer with large RAM?

• Slows down

• Run faster

• It does not affect anything

• Easy back-up

RAM requires a constant power. Why?

• Because, capacitors cannot hold their state without power.

• Because, it's made of transistors.

• Because, it's made of capacitors.

• Because transistor cannot hold their state without power.

Which of the followings are true?

• DRAM operates asynchronously with the system clock, therefore it is slow

• SDRAM operates asynchronously with the system clock, therefore it is slow

• DRAM operates synchronously with the system clock, , therefore it is fast

• SDRAM operates synchronously with the system clock, therefore it is fast

64 or 32 bit of data path refers to the number of bits of the data that are transferred in 1 clock cycle.

• True

• False

64 bit RAM transmits....

• 64 bytes of data in a clock cycle.

• 8 bytes of data in a clock cycle.

• 8 mbps of data in a data cycle.

• 32 mbps of data in a data cycle

How many bytes do 64 bit SDRAMs process in a cycle?

• = 64 / 8 8 bytes

• = 64 / 32 = 2 bits

• = 64 / 32 2 bytes

• = 64 / 8 8 bits
