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.
If an algorithm could potentially run forever, it wouldnât be very useful because you might never get an answer. Most algorithms are guaranteed to produce the correct result. Itâs rarely useful if an algorithm returns the largest number 99% of the time, but 1% of the time the algorithm fails and returns the smallest number instead. If an algorithm imposes a requirement on its inputs (called a precondition), that requirement must be met.
