Latency is important when someone is directly interacting with another computer, as the amount of lag between the two computers can make some tasks very difficult (such as editing a file). Bandwidth, on the other hand, is not concerned with latency. When downloading a large file, it may be perfectly acceptable to have a 3-4 second wait before the file begins to download. Networking latency is the time it takes for a single packet to go from your computer, to another host and back. Latency is generally measured in milliseconds.
The time it takes for a packet to cross a network connection, from sender to receiver. 2. The period of time that a frame is held by a network device before it is forwarded. Two of the most important parameters of a communications channel are its latency, which should be low, and its bandwidth, which should be high. Latency is particularly important for a synchronous protocol where each packet must be acknowledged before the next can be transmitted.
