Choose all the types of cache memory?

• L1i

• L1d

• L2

• L3

Choose all the registers found in a typical processor?

• Current Instruction

• Accumulator

• Memory Data

• Memory Address

What is meant by a von Neumann computer architecture?

• Where the program instructions are stored in a seperate memory storage from the data

• Where the program instructions are stored in the same memory storage as the data

• Where the program instructions are stored in ROM and the data is stored in RAM

• Where the program instructions are divided across several CPUs

What is the main storage area for program instructions and data in a Von Neumann computer architecture?

• RAM

• CPU

• ROM

• Cache

Which internal component carries out the processing of program instructions?

• CPU

• GPU

• RAM

• BIOS

What controls the timing of the instruction cycle in a computer

• The amount of RAM available

• The frequency of the internal clock

• The width of the address bus

• The size of addressable memory

Choose all statements that are TRUE about primary memory addresses

• Each one has a unique address

• They all store the same amount of data

• The number of addresses is determined by the width of the address bus

• Addresses are stored internally as hexadecimal numbers
