Targets for Computer Systems• Identify what the different parts of a computer are called and what they do• Recognise different kinds of computer systems• Understand why computer systems are important• Create a flow chart to show the sequence for programs to be stored and executed

Key term Definitionamplified Made larger or louderbinary A number system that uses 0s and 1s to represent codes and data. The binary system is the foundation on which digital

technology is built.bit patterns

Instructions stored by software and programs in patterns of 0s and 1s that tell a computer what to do

central processing unit (CPU) A tiny microprocessor that houses the core of a computer’s processing power on one chip – the ‘brain’ of a computer

data Information, dealt with by computers, in the form of symbols, characters, images and sounds, stored and transmitted as electrical signals

encoded Converted into a coded formfetch-decode-execute cycle The cycle in which CPUs run a program by retrieving, decoding and running each instruction

information Processed data; facts in a form that makes them useful and meaningful to humans

input The raw data received by a computer, which it then processes, for example, a mouse click

input device A device that puts data into a computer, e.g. a mouse, keyboard, temperature sensor or microphone

memory address

The storage location assigned to each set of instructions (bit patterns) that are organized consecutively by the processor so it can fetch, decode and execute them in the correct order

mission-critical Critical to the success of the ‘mission’ (task) being carried out; failure of a mission-critical system will result in the failure of the entire task

Moore’s law The statement that the number of transistors on an integrated circuit doubles every two years

motherboard The main circuit board in a computer; holds most of the essential electronic components as well as having connectors for peripherals

output The result of processing; the actions or information that a computer produces

output device A device that relays information from computers to the real world, e.g. a monitor, printer or speaker

peripheral A device that can be connected to a computer to put data in or take information out of the system

processing The action of a computer turning input data into output information or actions

RAM (random access memory) A type of data storage that allows data to be accessed in a random order, and to be read and overwritten. RAM does not preserve data when the computer is turned off.

robust Strong, sturdy, resistant to errors; a robust system will produce the correct output in spite of errors

ROM (read only memory) A type of data storage. Data stored in ROM cannot be modified easily, but is preserved when the computer is turned off.

transistor A device known as a semiconductor, used to switch and amplify electronic signals and power

Let’s read about Storage Devices

You will be looking at this presentation with your teacher

Key term Definitionbackup A second copy of a file in case the original copy becomes corrupt or is lost.

binary A number system that uses 0s and 1s to represent codes and data. The binary system is the foundation on which digital technology is built.
