Computers refer to the hardware, and since computers cannot initiate functionality on their own, they start functioning as soon as they receive data to work with (to process). Computers store, transmit, retrieve and manipulate data for businesses and other enterprises. Computers are used in Information Technology (IT) – which is a subset of ICT. In order for an ICT system to function, it needs to receive, store, retrieve, manipulate and transmit data.Ĭomputers are programmable electronic devices designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. Data can come in different formats, such as sounds, images, and videos, etc. Data – raw material that is processed by the system to provide the information for the output provided by the system.

Software – the computer programs which provide the step-by-step instructions to complete the task.This causes the passing of data or information between people. Procedures – to determine what needs to be done and when.input devices, storage, processor, output devices and communication devices.

People – to supply the data and to make decisions from the output supplied from the system information, which is based on the results from processing data and the output from an ICT system.

Information and Communication Technologies (ICT) refers to technologies that capture, transmit and display data and information electronically and includes all devices, applications and networking elements that allow people to connect in a digital world.Īn ICT system refers to the overall set-up, consisting of hardware, software, data and its users.

explain the information processing cycle.

provide an overview of a general model of a computer.

define Information and Communication Technologies (ICTs) and Information Technology.

Refer to the YouTube video to see how ICT has changed over the years. Over the last twenty years, the field of ICT has grown from a small niche field to one of the most important fields in the world. In practice, it refers to all the hardware, software, and systems essential to communicate electronically.

Information Communication Technologies (ICT) is the combination of computer-based technologies (such as computing devices and smartphones) with communication technologies (such as telephones, cell phones and the internet). Output device – a device that formats and presents data in a form understandable to a userĬommunication device – a hardware device capable of transmitting a signal over a wire or wireless connection. Processing device – a hardware device that receives the data, performs a set of instructions, and then returns the processed data to the RAM Random-access memory (RAM) – a hardware device, usually on the motherboard, that allows information and data to be temporarily stored and retrieved on a computer while it is on Storage device – a hardware device that is used for storing data Input device – any hardware or peripheral device that allows you to enter data into a computer or interact with a computer
