CPU

The CPU fetches instructions from.... and executes those instructions.

• Memory

• ALU

• ROM

• Input Device

The ALU is found inside the CPU True or False?

• True

• False

The acronym CPU stands for

• Common processing unit

• Central procedures unit

• Central processing unit

• Common procedures unit

Information used by the CPU is loaded first in

• ROM

• RAM

• CMOS

• Register

What is the main function of the CPU?

• To carry out processing of the data.

• To help with playing games.

• To fetch instructions from memory, decode them and execute the instructions.

• To heat up the computer.

Either stores the address from which data will be fetched from the CPU, or the address to which data will be sent and stored.

• MAR (Memory Address Register)

• MDR (Memory Data Register)

• CIR (Current Instruction Register)

• PC (Program Counter)

• ALU (Arithmetic and Logic Unit)

This register contains the address (location) of the instruction being executed at the current time

• MAR (Memory Address Register)

• MDR (Memory Data Register)

• CIR (Current Instruction Register)

• PC (Program Counter)

• ALU (Arithmetic and Logic Unit)

Holds the instruction that is being processed (and translated) or executed

• MAR (Memory Address Register)

Clock speed is measures in

• bytes
• bits
• time
• hertz

Tick all that could be ways of improving CPU performance

• Increase Clock Speed

• Increase Hard Disk Size

• Increase Data Bus Width

• Add more Cores

• Add more programs
