Question

Which of the following are TRUE for direct communication :(choose two)

a) A communication link can be associated with N number of process(N = max. number of processes supported by system)
b) A communication link can be associated with exactly two processes
c) Exactly N/2 links exist between each pair of processes(N = max. number of processes supported by system)
d) Exactly one link exists between each pair of processes

Answer 1

In direct communication, each communication link is associated with exactly two processes, and only one link exists between each pair of processes, ensuring a direct and exclusive line of communication between sender and receiver.

Step-by-step explanation:

In the context of direct communication between processes in computing:

• (b) A communication link can be associated with exactly two processes. This means that in a system employing direct communication, each pair of communicating processes share a single, dedicated link for their exchanges.
• (d) Exactly one link exists between each pair of processes. As each process pair has a single unique communication link, it inhibits the existence of multiple links for the same pair, ensuring a one-to-one relationship between sender and receiver.

It's important to note that these assertions are based on a direct communication model where each pair of processes has a dedicated communication channel. Other models might offer different paradigms of process communication in computing.
