Computer Science

controls the instructions and other components in the processor

calculator in the processor used to handle mathematical and logical operations

a selection of registers that are very small and fast memory locations in the processor

The processor

In this unit pupils will discover the difference between general purpose and embedded systems. They will examine computer architecture and the components that make up a processor. Pupils will recognise the need for storage and be able to select a suitable storage device for a given purpose.

Computer Systems

What is the term for the overall design and structure of a computer system?

to design a computer system that processes instructions and data

What is the main purpose of the von Neumann architecture?

directs operations and manages instructions

performs calculations and logic operations

regulates the timing of all CPU activities

temporarily stores data being transferred

Match each CPU component to its correct function:

What is the term for the pathway used to transfer data, addresses or control signals between components inside a computer?

holds the instruction currently being executed

keeps track of the address of the next instruction

temporarily stores the results of calculation

carries memory addresses from the CPU to other components

sends control signals to coordinate operations

Match each CPU component or bus to its correct function:

the CPU analyses and understands instructions like a person

the CPU ignores instructions it does not recognise

the CPU follows a set process to execute instructions using its components

the CPU asks the user for help with each instruction

Which statement best describes how the CPU deals with instructions it receives?

Match each example to the correct concept:

Which device would be considered a peripheral?

What does an operating system manage apart from hardware?

Which of these is NOT managed by the operating system?

What is the term for the part of a device that lets people interact with and control it?

Put these steps in order for connecting a peripheral device:
