The CPU is the brain of the computer, responsible for executing instructions, performing calculations, and controlling the flow of information between different components.

A web browser is a software application that allows users to access and interact with websites, while a search engine is a tool that helps users find information on the internet by searching through a vast database of websites.

A firewall is a network security system that monitors and controls incoming and outgoing network traffic, blocking unauthorized access and protecting the network from potential threats.

Artificial intelligence (AI) refers to the ability of computer systems to perform tasks that typically require human intelligence, such as understanding natural language, recognizing patterns, and making decisions.

The internet is a global network of computers that allows users to share information and communicate with each other, regardless of their physical location.

An operating system is a software that manages the computer's hardware and software resources, such as memory, storage, and input/output devices, and provides a platform for running application programs.

A computer program is a set of instructions that tells the computer how to perform a specific task, while an application is a software that performs a specific task, such as word processing, web browsing, or playing games.

RAM (random access memory) is a type of computer memory that stores data and instructions that are currently being processed by the CPU. It is volatile memory, meaning that the data stored in RAM is lost when the computer is turned off.

Gesture recognition is a technology that allows users to interact with a computer using gestures or movements. It uses sensors to track the user's movements and translate them into commands that the computer can understand.

A hard disk drive (HDD) is a type of computer storage device that stores data that is not currently being processed by the CPU. It is non-volatile memory, meaning that the data stored on an HDD is retained even when the computer is turned off.

A computer network is a group of computers connected together, while the internet is a global network of computers that connects computer networks around the world.

A GPU (graphics processing unit) is a specialized electronic circuit that accelerates the creation of images, videos, and other visual content.

Virtual reality (VR) is a technology that allows users to experience a simulated environment using a headset that blocks out the real world.

A sound card is an electronic circuit that processes and generates sound. It converts digital audio signals into analog signals that can be played through speakers or headphones.

Mixed reality (MR) is a technology that allows users to experience a combination of the real and virtual worlds, where virtual objects are superimposed onto the real world.
