Fork

Answer 1

fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software.

Question 2

Latency

Answer 2

IS WASTED TIME. Network latency is an expression of how much time it takes for a packet of data to get from one designated point to another. In some environments (for example, AT&T), latency is measured by sending a packet that is returned to the sender; the round-trip time is considered the latency.

Question 19

Timeout

Answer 19

Timeout - A specified period of time that will be allowed to elapse in a system before a specified event is to take place, unless another specified event occurs first; in either case, the period is terminated when either event takes place.
