A "Gigabit" is a unit of digital information that equals one billion bits. It is commonly used to measure data transfer speeds in computer networks and internet connections. For example, a gigabit per second (Gbps) indicates how quickly data can be downloaded or uploaded, making it a crucial factor for activities like streaming videos or online gaming. In the context of internet service, many providers offer gigabit plans to deliver faster speeds to homes and businesses. This allows users to enjoy smoother online experiences, especially when multiple devices are connected. Technologies like fiber optics are often used to achieve these high speeds.
