Question

a wireless access point (ap) is:
a a device that enables wireless systems to communicate with each other, even if they are on different networks.
b a wireless mode in which systems use only their network interface cards (nics) to connect with each other.
c a device that enables wireless systems to communicate with each other, provided that they are on the same network.
d a circuit board within a computer’s central processing unit that serves as the interface enabling the computer to connect to a network.

Explanation:

To determine the correct definition of a wireless access point (AP), we analyze each option:

• Option A: A wireless access point does not enable communication across different networks; it typically works within a single network's scope, so A is incorrect.
• Option B: The description in B refers to ad - hoc mode (where devices use NICs to connect directly), not a wireless access point, so B is incorrect.
• Option C: A wireless access point is a device that allows wireless systems (like laptops, smartphones) to communicate with each other and with the wired network, and this communication is possible when the devices are on the same network (the network the AP is part of), so this matches the definition of a wireless access point.
• Option D: A wireless access point is not a circuit board within a computer's CPU. Network interface cards (NICs) or other network - related components have different roles, and this description does not fit a wireless AP, so D is incorrect.

Answer:

C. a device that enables wireless systems to communicate with each other, provided that they are on the same network.
