Users have direct access to the physical main memory (RAM)

• FALSE

• TRUE

The four levels of memory hierarchy are

• Main Memory
  GPU
  CPU Registers
  Storage

• Physical Memory
  Logical Memory
  CPU Registers
  Virtual Memory

• Main Memory
  Caches
  CPU Registers
  Storage

• Main Memory
  Virtual Memory
  CPU Registers
  Storage

Logical addresses handling is done by the

• ULA

• System Bus

• OS Driver

• MMU

Computer memory which allows read and write operations

• ROM

• RAM

• EPROM

• USB

Reorder the following so it has decreasing latency (fastest to slowest)

• L1 Cache

• CPU Register

• HDD

• RAM

For accessing the physical memory, we use

• Address

• Instruction

• Driver

• We can't

Why we do not use processor registers as main memory in order to speed up the system?

• RAMs are as fast as registers

• They don't work for that

• It is too costly to do so

• We have better technology for doig it

Internally, physical address spaces are divided in blocks known as

• Pages

• Physical blocks

• Frames

• Mapping blocks

Page table status bit 'VALID' equals to 0 leads to

• Page fault

• Page found

• Page cannot be accessed by user

• Page present in RAM memory
