In the context of computer networks, jitter is the variation in latency as measured in the variability over time of the packet latency across a network. A network with constant latency has no variation (or jitter). Packet jitter is expressed as an average of the deviation from the network mean latency. However, for this use, the term is imprecise.
Metric threads are measured by the distance between two adjacent threads in millimeters (pitch). Threads on a standard (inch based) fastener are measured by counting the number of threads per inch. The tolerance system for metric threads is composed of a two sets of a number followed by a letter. The first set indicates the pitch diameter tolerance, and the second set indicates the major diameter tolerance.
