Definition of: Quasi-Static Channel A quasi-static channel refers to a communication channel where the channel conditions (such as path loss, shadowing, and multipath fading) vary with time, but the rate of change is slow enough that the channel can be considered static over the duration of a single data transmission.

Definition of Joint Photographic Experts Group (JPEG) The Joint Photographic Experts Group (JPEG) refers both to a standard for compressing image data and to the committee that developed the standard. The JPEG standard is one of the most widely used and recognizable formats for digital images across the internet and

Definition of Grandfather-Father-Son Backup Strategy The Grandfather-Father-Son (GFS) Backup Strategy is a popular method of data backup that organizes data backups into three distinct generations: daily (Son), weekly (Father), and monthly (Grandfather) backups. This hierarchical approach ensures that an organization can maintain multiple copies of data over different time periods,

Definition of Gaussian Blur Gaussian Blur is a widely used effect in image processing that applies a Gaussian function to smooth or reduce detail and noise in images. Named after the mathematician Carl Friedrich Gauss, this technique uses a mathematical formula to transform each pixel in the image, taking into

Definition of Network Hub A network hub is a networking device that connects multiple computers or other network devices together in a Local Area Network (LAN). It operates at the physical layer (Layer 1) of the OSI model and functions by receiving a packet on one port and broadcasting it

Tracert, short for “Trace Route,” is a command-line utility that helps users diagnose the path taken by packets across an IP network from a source to a destination. It is an invaluable tool for understanding network routing issues and performance bottlenecks. By sending a series of Internet Control Message Protocol

Vue CLI, or Vue Command Line Interface, is a powerful tool developed by the Vue.js team to facilitate the rapid development of Vue.js applications. It provides a standardized system for scaffolding new projects, adding plugins, and managing various aspects of the application lifecycle, from development to production. By automating tedious

The TRIM command is an essential feature in solid-state drives (SSDs) that helps maintain the drive’s performance over time. Unlike traditional hard disk drives (HDDs) that use spinning disks and read/write heads, SSDs store data on flash memory. However, flash memory cells must be erased before new data can be

Git Clone is a fundamental command in the Git version control system that enables users to create a local copy of a remote repository. This command is crucial for developers looking to collaborate on projects, as it allows them to work on the project locally on their machines. By copying

Git Stash is a versatile feature in the Git version control system that allows developers to temporarily shelve (or stash) changes they have made to their working directory so that they can switch contexts or branches without committing incomplete work. This command essentially provides a safe space for modifications that

Git revert is a powerful command within the Git version control system that is used to undo changes made to a project’s history. This command creates a new commit that applies the inverse of the changes from a specified commit. Unlike other methods that may alter the project’s history, such
