What characterizes ad hoc mode in wireless networking?

1. It requires planning and coordination

2. It connects devices through an access point

3. Devices communicate directly without an access point

4. It is always used for long-term connections

The correct answer is: Devices communicate directly without an access point

Ad hoc mode in wireless networking is characterized by devices communicating directly with each other without the need for an access point. In this mode, devices establish a peer-to-peer connection, allowing for a quick and flexible way to share data directly, which is particularly useful in situations where there is no existing infrastructure. This setup is often advantageous for temporary or impromptu networks, such as when users want to connect their devices in a small area for sharing files or gaming without needing to set up a central network device. Since there is no access point involved, it simplifies the networking process, making it easy for users to connect automatically if they are within range. In contrast, options that imply the necessity of planning and coordination or that focus on connecting through an access point do not apply to ad hoc mode, as this type of connection is inherently decentralized. The idea of ad hoc mode being primarily suited for long-term connections also misrepresents its primary use case, which is more about temporary, flexible connectivity rather than stable, long-term networking solutions.
