Bandwidth and latency are crucial metrics in network communications. Bandwidth refers to the maximum amount of data transferred over a network in a given time, typically measured in bits per second. It determines the data throughput capacity. In contrast, latency measures the time delay experienced in transmitting data from its source to destination, often expressed in milliseconds. High bandwidth allows for quicker data transfer, while low latency ensures faster response times. Together, these factors impact the overall performance and user experience of network services.
