ICT vocabulary and definitions

What is the hardware of a computer?

• The programs that make the computer work.

• The physical parts of a computer system.

• The data stored on the computer.

Answer explanation

The hardware of a computer refers to the physical components, such as the CPU, RAM, and hard drive, that make up the computer system. This distinguishes it from software, which includes programs and data.

What are the most common input devices?

• Keyboard, mouse, microphone.

• Printer, speakers, projector.

• Hard drive, USB memory.

Answer explanation

The most common input devices are those used to provide data to a computer. A keyboard and mouse are standard for text and navigation, while a microphone allows for audio input, making 'Keyboard, mouse, microphone' the correct choice.

What is RAM memory?

• External storage device.

• Permanent memory for configuration data.

• Temporary memory where data is stored.

Answer explanation

RAM (Random Access Memory) is a type of temporary memory used by computers to store data that is actively being used or processed. It is volatile, meaning it loses its data when the power is turned off, unlike permanent storage.

What function does the operating system have?

• Manage hardware and software resources.

• Store data permanently.

• Execute user programs.

Answer explanation

The operating system primarily manages hardware and software resources, ensuring efficient operation and coordination between them. While it can execute user programs and store data, its main function is resource management.

What are output devices?

• Devices that display the results of the processor.

• Devices that input data into the computer.

• Devices that store data.

Answer explanation

Output devices are specifically designed to display the results of the processor, such as monitors and printers. This distinguishes them from input devices, which provide data to the computer, and storage devices, which save data.

What is an operating system (OS)?

• A system that does not interact with the user.

• A type of hardware that connects devices.

• A program that is only used on mobile devices.

• A software that manages hardware and software resources.

Answer explanation

An operating system (OS) is essential software that manages both hardware and software resources, enabling the computer to function effectively. The other options incorrectly describe hardware or limit the OS to mobile devices.

What is the difference between CLI and GUI?

• CLI is easier to use than GUI.

• CLI requires typing commands, GUI uses icons.

• GUI is only for mobile devices.

• CLI does not allow user interaction.

Answer explanation

The correct choice highlights that CLI (Command Line Interface) requires users to type commands, while GUI (Graphical User Interface) allows interaction through icons, making it visually intuitive.

What does a switch do in a network?

• Provides access to the Internet.

• Verifies information packets between networks.

• Connects multiple devices in a local network.

• Sends radio waves between devices.

Answer explanation

A switch connects multiple devices in a local network, allowing them to communicate with each other efficiently. This is the primary function of a switch, distinguishing it from other network devices.

What is a router?

• A device that is only used in local networks.

• A type of software for managing networks.

• A device that connects different networks.

• Hardware that has no Internet connection.

Answer explanation

A router is primarily a device that connects different networks, allowing data to flow between them. This distinguishes it from software or devices limited to local networks or without Internet connectivity.
