Introduction to Computers

An electronic device that processes data based on instructions, accepts data as input, processes it, produces information as output, and stores data for later retrieval.

Raw, unorganized facts and figures that lack context or meaning. It's like a collection of ingredients without a recipe.

Data that has been processed, organized, and given meaning. It provides context and answers questions.

Understanding gained through experience, knowledge, and analysis. It's like knowing how to cook a dish, not just having the ingredients and instructions.

A small, single-user computer designed for personal use. It typically includes a keyboard, monitor, and storage device.

A powerful computer designed for specialized tasks. It features a powerful processor and a high-quality display.

A multi-user computer capable of supporting many users simultaneously.

A category of computers based on their size and processing power.

A powerful computer that can support many users simultaneously. Think of it as a giant computer that can handle lots of tasks at once.

An extremely fast computer designed for complex calculations and scientific research. It processes information much faster than regular computers.

A portable computer that can be used in various locations. It has most of the features of a desktop computer but is designed for mobility.

A small, lightweight laptop optimized for portability. It's often less powerful than a regular laptop but ideal for tasks like browsing the web and checking emails.

A handheld computer, usually designed to be compact and portable. It can be used for various tasks, like making calls, sending messages, and browsing the internet.

A type of mobile device that uses a touchscreen interface without a keyboard or touchpad. It's great for consuming media, browsing the web, and playing games.

A powerful mobile phone that can run various applications in addition to phone calls. It's basically a small tablet computer with a touchscreen interface.

Any computer that is not a mainframe, supercomputer, laptop, netbook, or mobile device. It is usually a desktop and is not portable, typically used in homes or offices.

The central processing unit (CPU) is the brain of the computer. It's responsible for executing instructions, processing data, and controlling all the other components of the computer.

A keyboard is an input device used to type in data, text, and commands into a computer.

A mouse is an input device commonly used to control a computer cursor on the screen. It allows users to select, drag, and interact with objects within a graphical user interface (GUI).

A monitor is an output device that displays visual information from the computer. It presents text, images, videos, and other content for the user to see.

A hard disk drive (HDD) is a storage device used to permanently store data on a computer. It holds the operating system, applications, and user files.

A printer is an output device that produces hard copies of documents, images, and other information on paper or other media. It allows users to create physical copies of digital content.

ROM, or read-only memory, is a type of memory that contains permanent data and instructions, such as the boot firmware that a computer needs to start up. This data is stored in ROM and is not easily changed.

A combination of electronic circuits that acts as the central hub for a computer, connecting and controlling all other components.

A specialized electronic circuit that converts digital data into sound waves.

An electronic circuit responsible for generating visual output on a monitor.

A set of instructions that tell a computer what to do.

Software that manages the fundamental operations of a computer system, allowing other software to run properly.

Software designed to perform specific tasks for users, like word processing, web browsing, or playing games.

Software that is embedded into hardware to perform a specific function.

Software that requires users to purchase a license to use it.

Software that is freely available for use, modification, and distribution.
