Bandwidth is the capacity or data transfer rate of a network or communication channel. It measures the amount of data that can be transmitted over a network connection within a given time period, typically expressed in bits per second (bps), kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps).
A higher bandwidth indicates a greater capacity to transmit data quickly and efficiently, allowing for faster data transfers, smoother streaming of media content, and better performance in digital communication, including internet browsing, video conferencing, and online gaming. Bandwidth is a critical consideration in designing and managing networks, as it directly impacts the speed and quality of data transmission.
