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…

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…

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…

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…

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,…

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…

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…

The Central Processing Unit (CPU) is often considered the “brain” of a computer. It’s a crucial component responsible for executing instructions and performing calculations necessary to carry out tasks within a computer system. The CPU interacts closely with other components such as memory, storage, and input/output devices to process data and execute programs. Here are…

An All-Flash Array (AFA) is a type of storage array system designed to leverage solid-state drives (SSDs) exclusively for data storage, retrieval, and management. Unlike traditional storage arrays that may use a combination of spinning disk drives and SSDs, AFAs use SSDs across the board for enhanced performance, reliability, and efficiency. The key characteristics and…
