• Hardware refers to the physical components of a computer system, including the processor, memory, storage devices, input/output devices, and other tangible parts.
• Software comprises the programs, instructions, and data that tell the computer's hardware what to do. This includes applications, operating systems, and utilities.
• A desktop computer is a personal computer designed to sit on a desk. It typically consists of a computer tower (CPU), monitor, keyboard, and mouse.
• A laptop computer, also known as a notebook, is a portable computer that integrates all its components into a single compact device.
• The information processing cycle is a sequence of steps that a computer follows to process data: input, processing, output, and storage.
• Processing involves the computer's CPU executing instructions to manipulate and transform input data into meaningful output.
• Output is the result of processed data presented to users through devices like monitors, speakers, or printed documents.
• Storage refers to the long-term retention of data and programs on a computer using devices such as hard drives, SSDs, or cloud storage.
• Data consists of raw, unprocessed facts and figures, such as text, numbers, and images. It lacks context or meaning until it's processed.
• Information is data that has been processed, organized, and contextualized to provide meaning, relevance, and usefulness.
• Booting is the process of starting or initializing a computer. It involves loading the operating system into memory and preparing the system for use.
• Memory refers to RAM (Random Access Memory), used for temporary data storage.
• A QWERTY keyboard is the standard keyboard layout used on most English-language keyboards. It's named after the first six letters in the top row of keys.
• An operating system is system software that manages computer hardware, provides services to software applications, and facilitates user interaction with the computer.
• A Graphical User Interface is a visual interface that allows users to interact with a computer using graphical elements like icons, windows, and menus, as opposed to text-based interfaces.
• Input is the process of entering data or instructions into a computer using devices like keyboards, mice, touchscreens, or microphones.
• The information processing cycle is a sequence of steps that a computer follows to process data: input, processing, output, and storage.
• Application software is a type of software designed to perform specific tasks or functions for the user, such as word processing, spreadsheet calculations, or image editing.
• Utility software are programs designed to perform maintenance, management, and optimization tasks on a computer system. Examples include antivirus, disk cleanup, and backup tools.
• An interface is a point of interaction between a user and a computer or between different software components. It can be graphical (GUI) or text-based (CLI) and allows users to communicate with the computer or software.
• A word processor is an application software used for creating, editing, and formatting text documents. It provides features like text formatting, spell-checking, and document layout options.
• A spreadsheet is an application software used for organizing, analyzing, and performing calculations on numerical data. It typically consists of rows and columns, allowing users to create tables and formulas.
• A database is a structured collection of data organized in a way that allows for efficient retrieval, storage, and manipulation of information.
• Presentation software, often used for creating slideshows, allows users to combine text, images, and multimedia elements to convey information effectively.
• Communication software enables users to communicate over computer networks. Examples include email clients, instant messaging apps, and video conferencing tools.
• An office suite is a bundle of various application software commonly used in an office environment. It typically includes word processing, spreadsheet, presentation, and email software, among others.
• Desktop publishing software is used for designing and formatting documents for print or digital publication.
• Web authoring software assists in creating and designing websites. It may offer features for webpage layout, HTML coding, and integrating multimedia elements.
• A web browser is application software that allows users to access and view web pages on the internet.
• A plug-in is a piece of software that adds specific functionality or features to an existing application. For example, playing multimedia content or blocking ads.
• Bluetooth is a wireless technology standard used for short-range communication between devices, enabling data and file transfers, audio streaming, and peripheral connections without cables.
• A USB port is a common interface on computers and devices used for connecting peripherals like keyboards, mice, external drives, and smartphones.
• LCD is a type of flat-panel display technology that uses liquid crystals to create images on screens, commonly used in computer monitors and TVs.
• Screen size refers to the physical measurement of the diagonal distance from one corner of a display screen to the opposite corner, usually expressed in inches.
• Resolution is the measure of the number of pixels (dots) that make up an image on a display screen, typically expressed as the number of pixels in width by height (e.g., 1920x1080 for Full HD).
• A graphics card is a dedicated hardware component responsible for rendering images and videos on a computer screen. It enhances graphics performance for tasks like gaming and rendering.
• Response time measures how quickly pixels can change from one color to another. Lower values are desirable for fast-paced activities like gaming.
• VGA is an older video display standard and connector used to transmit analog video signals from a computer to a monitor.
• HDMI is a modern standard for transmitting high-quality digital audio and video signals between devices, including computers and monitors or TVs.
• A printer is a peripheral device that produces hard copies of digital documents or images on paper or other media. Common types include inkjet, laser, and 3D printers.
