ITPEC IP April 2019 Question 30
ITPEC IP April 2019 — Question 30 of 100
Devices from different manufacturers or running different operating systems can communicate when they implement the same communication protocol. A protocol defines shared rules such as message formats, sequencing, timing, and responses, enabling interoperable exchanges.
Answer (d)
Why not others:
- (a) is false because protocols can also govern analog communication
- (b) is false because protocols may be proprietary or developed by manufacturers as well as standards bodies
- (c) is false because protocols also define error handling and exceptional behavior
Key rule: Communication succeeds when both endpoints follow compatible rules, regardless of their internal hardware, vendor, or operating system.
