Question

synchronisation of timing is​

Answer 1

$\huge\fbox\red{❥answer}$

Clock Synchronization

This hardware clock is used by the computer's software clock to track the current time. There are several methods for synchronizing physical clocks. External synchronization means that all computers in the system are synchronized with an external source of time (e.g., a UTC signal).

Answer 2

Answer:

Generally, timing is a challenging an important issue in building distributed systems. Consider a couple of examples:

A distributed, real time auction where the system must know which of two bidders submitted their bid first.

A TDMA protocol that requires coordination among sensor nodes.

A MAC protocol that requires coordination among sensor nodes.

An application that determines the angle of arrival of an acoustic signal by analyzing the times at which the signal reaches an array of sensors.

In some cases, it may be sufficient to know the order in which events occur. This is referred to as logical time. In other cases, it is necessary that two computing devices be synchronized with respect to physical time.
