the technology required for information processing, in particular, the use of electronic computers, communication devices and software applications to convert, store, protect, process, transmit, and retrieve information from anywhere, anytime.
ICT
refers to the knowledge obtained from reading, investigation, study, or research
information
an act of transmitting messages; a process whereby information is exchanged between individuals using symbols, signs or verbal interactions
communication
the use of scientific knowledge, experience and resources to create processes and products that fulfill human needs; vital in communication

a device that stores and processes information according to a set of instructions
computer
the physical, touchable, electronic and mechanical parts of a computer system
hardware
the main part of a microcomputer, sometimes called the chassis; includes the following parts: motherboard, microprocessor, memory chips, buses, ports, expansion slots and cards
system unit
the main circuit board of a computer; contains all the circuits and components that run the computer
motherboard/mainboard/system board
the main “brain” or “heart” of a computer system
CPU (Central Processing Unit)
the computer’s working storage space that holds data, instructions for processing and processed data (information) waiting to be sent to secondary storage. Physically, it is a collection of RAM chips.
primary storage
is a non-volatile, meaning it holds data even when the power is ON or OFF
ROM (Read Only Memory)
is volatile, meaning it holds data only when the power is on
RAM (Random Access Memory)
a data pathway between several hardware components inside or outside a computer
expansion bus
printed circuit boards (also called interface cards) that enable the computer to use the peripheral device for which it does not have the necessary connections or circuit boards
adapters
installed in the back corner of the PC case, next to the motherboard
Power Supply Unit (PSU)
also known as hard drive, is a magnetic storage device that is installed inside the computer
Hard Disk Drive (HDD)
a storage device that uses lasers to read data on the optical media. There are three types of optical drives: Compact Disc (CD), Digital Versatile Disc (DVD), and Blu-ray Disc (BD)
Optical Drive
designed to optically access data stored on a DVD
Digital Versatile Disc (DVD)
data is inputted to the computer through a keyboard
keyboard entry
the first input device developed for the PC. Data is transferred to the PC over a short cable with a circular 6-pin Mini-din connector that plugs into the back of the motherboard
keyboard
a form of input that does not require data to be keyed by someone sitting at a keyboard
direct entry
an input device used to move the pointer (cursor) on screen
pointing devices
the most common ‘pointing device’ used in PCs
mouse
a display screen that is sensitive to the touch of a finger or stylus
touch screen
a light-sensitive stylus wired to a video terminal used to draw pictures or select menu options
light pen
a graphics drawing tablet used for sketching new images or tracing old ones; also called a “graphics tablet”, the user contacts the surface of the device with a wired or wireless pen or puck
digitizer tablet
displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen or video display terminal
computer display monitor
utilize two sheets of polarizing material with a liquid crystal solution between them
LCD projectors
a type of display screen that has a touch sensitive transparent panel covering the screen, which is similar to touch screen
smart board
a device that prints text or illustrations on paper
printer
used to play sound
speaker
