Assertion (A) : Open Systems Interconnection allows connectivity of ICT components.

Reason (R) : Network Printer goes slow if it is OSI compatible.

  • A.Both (A) and (R) are true.
  • B.Both (A) and (R) are false.
  • C.(A) is false, but (R) is true.
  • D.(A) is true, but (R) is false.

Answer: D

Open Systems Interconnection, the OSI reference model, provides a standard so that computer and communication equipment from different makers can be connected, so (A) is true. The reason is false: compatibility with OSI does not slow down a network printer, and a network printer is no slower for being OSI compatible. So (A) is true and (R) is false, option (D). The option calling both true takes the false reason, and the other options reject the true assertion.
