A(n) _____ has every computer with a wireless network adapter communicating directly with every other device with a wireless network adapter.

A) network
B) infrastructure network
C) ad hoc network
D) wireless network

An ad hoc network is a decentralized type of wireless network where every computer or device with a wireless network adapter communicates directly with every other device with a wireless network adapter, without the need for a central infrastructure or access point. This is in contrast to an infrastructure network, where devices connect through a central access point or router. Therefore, the correct answer is C) ad hoc network.
