Meaning of Data Data refers to raw facts or entities to which no meaning has been assigned, as they have not undergone any processing. It encompasses information about individuals, locations, objects, and their respective activities.   When data undergoes manipulation to organize and derive meaning or achieve a specific outcome, it is considered processed. The […]

What are Output Devices? Output devices are components of a computer system that allow the computer to communicate information to the user or to other devices. They convert electronic data into human-readable or machine-understandable forms. Examples of Output Devices 1. Monitor/Display: This is the most common output device, which displays visual information such as text,

What are computer Input Devices? Computer input devices are hardware components that allow users to interact with a computer system by providing data or instructions. These devices enable users to input information into the computer for processing, manipulation, and communication. Common examples of computer input devices include: 1. Keyboard: A primary input device used for

Development of Computing Devices in the 20th Century The computing devices of the 20th century underwent significant historical development, marked by the emergence of computer generations utilizing vacuum tubes for circuitry and magnetic drums for memory. These early computers were massive, occupying entire rooms, and were characterized by high costs, substantial heat generation, often leading

Historical Development Of Computing Devices 2 (Pre-Computer Age To 19th Century) Jacquard’s Loom (Features, Components, And Uses) Joseph Marie Jacquard invented the Jacquard loom in 1801, a mechanical device simplifying the production of textiles with intricate patterns like brocade, damask, and matelassé. Controlled by punched cards containing holes, each row corresponding to a design row,

Development of Computing Devices Through History Computing devices trace their roots back to the time when our ancestors utilized early calculation tools for counting purposes. One such method involved counting with fingers and toes, where calculations were performed manually before the advent of computers. As the need for more sophisticated counting methods arose, early humans

Meaning of Computer Hardware: Computer hardware refers to the tangible physical units or components that constitute the configuration of a computer. This term encompasses the visible and touchable parts of a computer system.   Examples of Hardware Components: Monitor Motherboard CPU (Central Processing Unit) RAM (Random Access Memory) Expansion Cards Power Supply Optical Disk Drive

A computer, often described as a remarkable marvel of modern technology, is a specialized multi-purpose electronic device, commonly referred to as a machine. This sophisticated apparatus possesses the extraordinary ability to receive instructions in the form of data, adeptly store and process this information, and subsequently deliver precise results at an astonishingly high speed. Comprising

Logic Gates A fundamental component of digital circuits, a logic gate is a basic building block. Typically, these gates possess two inputs and one output. At any given moment, each terminal is in either a low (0) or high (1) binary condition. The state of a terminal in a logic gate can frequently change as

Secondary Memory Secondary memory or storage refers to non-volatile memory located externally from the computer. It is utilized for storing large amounts of data, offering permanent or long-term storage for data or programs, as well as serving as a backup storage solution. Various criteria can be used to classify secondary storage media: (i) Retrieval speed:

Memory in a computer serves as the repository for data and instructions required for processing. It retains programs and data only for the duration of the operation of the corresponding program. Types Of Memory Primary Memory Secondary Memory   (a) Primary Memory This is the type of memory directly accessible by the CPU, engaging in

The primary function of the CPU is to execute mathematical computations on binary numbers, yet there are additional purposes for utilizing the CPU. It comprises various hardware components like the motherboard and circuits.   A central processing unit (CPU) represents the hardware within a computer responsible for executing a computer program’s instructions by conducting fundamental

The term “computer hardware” encompasses the tangible components that together form a computer system. It refers to the physical constituents, such as the monitor, mouse, keyboard, computer data storage, hard disk drive (HDD), system unit (inclusive of graphic cards, sound cards, memory, motherboard, and chips), among others. These are physical objects that can be physically

The internet comprises a globally interconnected computer network that offers an extensive range of information on virtually any conceivable topic. The World Wide Web, commonly referred to as the Web, constitutes a subset of the Internet.   Meaning of Internet The Internet is a global network of computers designed for sharing information, with information sharing

BASIC has a number of built-in functions that greatly extend its capability. These functions perform such varied task as taking the square root of a number, counting the number of characters in a string, and capitalizing letters. Functions associate with one or more values, called input, a single value called output.   NUMERIC FUNCTIONS: SQR,
