J277 Architecture and Factors that effect performance

The processor…

• Carries out instructions

• Is main memory

• Is secondary storage

• Is an input device

The CPU is:

• Control processing unit

• Centralised process unit

• Central process unified

• Central processing unit

This is a secondary storage

• CPU

• GPU

• USB

• RAM

The cache memory...

• does any maths or logic problems for the CPU

• stores frequently used instructions close to the CPU

• sends out control signals for the CPU

• holds specific data for the fetch-decode-execute cycle

The main computer components are:

• Input/Output/CPU/Main memory

• CPU/Main memory/Secondary storage

• Input/Output/CPU/Main memory/Secondary storage

• CPU/Main memory/Secondary storage

The CU...

• does any maths or logic problems for the CPU

• stores data inside the CPU

• sends out control signals for the CPU

• holds specific data for the fetch-decode-execute cycle

This carries address of the next instruction that will be fetched

• Address bus

• Data bus

• Control bus

• System bus

This would perform an operation such as 5+8 ?

• Arithmetic Logic Unit

• Accumulator

• Cache

• Control Unit

Firmware in which software and hardware are integrated on a circuitboard is often used in what type of system?

• Desktop System
• Embedded System
• Operating System
• Point of Sales System

What is transferred down the data bus?

• Data only

• Addresses only

• Data and instructions

• Data, instructions and addresses
