VGA – Video Graphics Array
Video Graphics Array (VGA) is a standard display interface introduced by IBM in 1987. It was one of the first widely adopted graphics standards for displaying video on computer monitors. VGA became the de facto standard for computer displays in the late 1980s and throughout the 1990s, and it remained in widespread use for many…

SSD – Solid State Drive
A Solid State Drive (SSD) is a type of storage device that stores data persistently using integrated circuit assemblies as memory to store data. Unlike traditional hard disk drives (HDDs), which use spinning magnetic disks and mechanical arms to read and write data, SSDs have no moving parts and store data electronically. Here are some…

SATA – Serial Advanced Technology Attachment
Serial Advanced Technology Attachment (SATA) is a computer bus interface used to connect storage devices such as hard disk drives (HDDs), solid-state drives (SSDs), and optical drives to the motherboard of a computer. SATA interfaces have largely replaced older parallel ATA (PATA) interfaces due to their improved performance and smaller cables. Here are some key…

ROM – Read Only-Memory
Read-Only Memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. As the name suggests, ROM retains its stored data even when the power is turned off. Unlike Random Access Memory (RAM), ROM is not typically used for storing data that needs to be frequently modified or accessed during normal…

RAM – Random Access Memory
Random Access Memory (RAM) is a type of computer memory that is used to store data and machine code currently being used or processed by a computer’s CPU (Central Processing Unit). Unlike storage devices such as hard drives or solid-state drives (SSDs), which retain data even when the computer is powered off, RAM is volatile…

RAID – Redundant Array of Independent Disks
Redundant Array of Independent Disks (RAID) is a technology used to combine multiple physical disk drives into a single logical unit for the purpose of data redundancy, performance improvement, or both. RAID configurations are commonly used in servers, storage systems, and high-performance computing environments to enhance data reliability, availability, and performance. There are several RAID…

PC – Personal Computer
A Personal Computer (PC) is a general-purpose computing device designed for individual use, typically by one person at a time. PCs come in various form factors, ranging from desktop computers to laptops, notebooks, and even smaller devices like tablets and smartphones. Here’s an overview of the components and features commonly found in a PC: Overall,…

OS – Operating System
An Operating System (OS) is a software program that serves as the intermediary between the hardware of a computer system and the applications or user-level software running on it. It manages the computer hardware and provides common services for computer programs. Here are the key functions and components of an Operating System: Examples of popular…

LCD – Liquid Crystal Display
A Liquid Crystal Display (LCD) is a flat-panel display technology used in a wide range of electronic devices, including computer monitors, television screens, smartphones, tablets, and digital signage. LCDs create images by manipulating light through a layer of liquid crystals sandwiched between two polarized glass filters. Here’s how LCD technology works: LCDs offer several advantages…

HDD – Hard Disk Drive
A Hard Disk Drive (HDD) is a non-volatile data storage device used in computers and other electronic devices to store and retrieve digital information. It consists of one or more rotating magnetic disks or platters coated with a magnetic material, along with read/write heads that move across the surface of the platters to read and…
