What is the CPU KS3?
The CPU (Central Processing Unit)
The job of the CPU is to process all that data and instructions to make the computer system work.
The processing power of a CPU depends on: • Clock speed - The number of instructions a single processor can carry out per second (Hz)..
Using a network allows you to share:
hardware, such as a printer.software, allowing multiple users to run the same programs on different computers.data, so that other people can access shared work and you can access your data from any computer on the network.
Computers use binary numbers, 0 and 1.
This is because computers use switches and a switch can only be ON or OFF.
The Binarynumber system is referred to as Base 2.
Key stage 2
Pupils should be taught to: ▪ design, write and debug programs that accomplish specific goals, including controlling. or simulating physical systems; solve problems by decomposing them into smaller. parts.
KS1 Computing Curriculum
understand what algorithms are; how they are implemented as programs on digital devices; and that programs execute by following precise and unambiguous instructions. create and debug simple programs. use logical reasoning to predict the behaviour of simple programs.
