Which term describes a type of wireless network where connected devices communicate directly with each other instead of over an established medium?

• A. Ad hoc network
• B. Bluetooth
• C. NFC
• D. TLS

Answer: (A)

This question tests understanding of networks that form without fixed infrastructure and allow devices to talk directly to one another. An ad hoc network is a decentralized setup where each node can communicate directly with other nodes, without a central access point or pre-existing backbone. It forms spontaneously as devices come into range and can adapt on the fly, which fits the idea of communicating directly without relying on an established medium. Bluetooth and NFC describe specific wireless technologies used for short-range, direct links, but they operate within predefined frameworks and aren’t about the broader network model. TLS is a security protocol used to protect communications, not a type of network.
