Y10 Hardware - Lesson recap 1

What is the purpose of RAM?

• To store your files for long term

• To hold the data and instructions for open programs

• To provide security to a system

• To allow automatic backups to be stored

What is the main feature of the Von Neumann architecture?

• Data and instructions are stored together in memory

• More components such as the ALU and Control Unit

• Faster way to access memory

Which of the following are true for RAM

• Can read from and write to

• Is volatile

• Is read-only

• Is non-volatile

The ________________________ is the register that holds the address of the next instruction to be fetched.

_________ are fast memory locations used during the FDE cycles

Which of these three statements best describes the control unit?

• Completes calculations

• Manages the flow of signals to other components

• Holds frequently used instructions

If a CPU clock speed is 3.7GHz; how many FDE cycles per second can it complete?

• 3.7 Million

• 3.7 Billion

• 3.7 Trillion

• 3.7 Thousand

Which of these statments are true for cache memory?

• Is volatile

• Is faster to access than RAM

• Is slower to access that RAM

• Is non-volatile

The _____________ completes arithmetic and logical calculations during the execute stage.

Having more cores in a CPU means that...

• The clock speed is increased

• More FDE cycles can be processed simultaneously

• The Cache is bigger

• The CPU genertaes less heat
