Which term denotes a wireless network where devices connect directly to each other without an established infrastructure?

• A. Cipher suite
• B. Bluejacking
• C. Tethering
• D. Ad hoc network

Answer: (D)

The concept here is a wireless setup where devices connect directly to each other without a central infrastructure like an access point. This is called an ad hoc network, a peer-to-peer wireless arrangement that allows devices to communicate directly without an established network infrastructure. It’s useful for quick, temporary connections—sharing files or playing games without a router—but it can have limitations in range, scalability, and security because there’s no central controller managing the network. Cipher suite is about the cryptographic algorithms used to secure communications. Bluejacking is a Bluetooth prank involving unsolicited messages. Tethering involves sharing a device’s internet connection with others, which typically relies on a broader network rather than a direct device-to-device ad hoc link.
