Key term
bit patterns
Definition
Made larger or louder
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.
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
encoded
fetch-decode-execute cycle
Information, dealt with by computers, in the form of symbols, characters, images and sounds, stored and transmitted as
electrical signals
Converted into a coded form
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
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
The statement that the number of transistors on an integrated circuit doubles every two years
amplified
binary
mission-critical
Moore’s law
output
The main circuit board in a computer; holds most of the essential electronic components as well as having connectors for
peripherals
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)
robust
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.
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
motherboard
