Internet speed refers to how quickly data is transmitted over the internet. It is usually measured in megabits per second (Mbps) and indicates how fast you can download or upload files, stream videos, or browse websites. Higher speeds allow for smoother online experiences, especially when multiple devices are connected. Factors affecting internet speed include the type of connection, such as fiber optic, cable, or DSL, as well as network congestion and the distance from the service provider. Users can test their internet speed using various online tools to determine if they are getting the service they pay for.
