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

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.
binary digits The 1s and 0s used to represent ‘on’ and ‘off’ in binary.bits See binary digits.byte A unit of digital information consisting of eight bits.cloud storage A type of remote data storage whereby a user stores files on a server accessed over the internet. Examples of cloud storage options include
Dropbox and Google Drive.
corrupt Damaged and no longer readable by a computer.data Information stored and transmitted by computers as electrical signals. Data is unprocessed information that is meaningless to humans due
to lack of structure.

interface The combination of software and input devices that allow a user to interact with a program.
kilobyte (KB) A unit of computer memory consisting of 1,024 bytes.magnetic storage A type of data storage that uses different patterns of magnetization on a disk to represent binary digits. Hard disks, floppy disks and
cassette tapes use magnetic storage.
megabyte (MB) A unit of computer memory consisting of 1,000 kilobytes.memory Another word for data storage.non-volatile Describes a type of computer memory that retains its data when the computer is switched off. Opposite: volatile.
operating system Software that supports a computer's basic functions, such as running programs and controlling peripherals. Windows, Mac OS and Linux are all operating systems.
