IC3 Computer Fundamentals (1st test in the IC3
Series. This will help you prepare) 2024.
Input
The data that is entered into a computer.
Processing
The manipulation of data by a microprocessor or embedded processor according to instructions given to
it by a program or embedded in the chip itself.
Storage
In computing, any device in which (or on which) information is stored.
Output
The computer generated information that is displayed to the user in some discernible form such as a
screen display, printed page, or sound.
Hardware
The physical parts of the computer system that you can touch and feel such as the keyboard, monitor,
and computer case.
Software
The programs and data that make computer hardware function.
Microprocessor
The main processing unit of a computer or information processing device; the "brains" of the machine
carrying out instructions, performing calculations, and interacting with the components used to operate
the computer.
Binary
Numbering system of 1s and 0s; these two unique number represent the charged or uncharged nature of
electricity.
RAM
The memory that is available on a computer for storing data and programs currently being processed. It
is automatically erased when the power is turned off.
ROM
Stored permanent systems instructions, which are never changed; it holds its contents even when the
power is turned off.
