What is a network that provides wireless connectivity without the need for a centralized management point called?

• A. Ad hoc network
• B. Mesh network
• C. Infrastructure network
• D. Point-to-point network

Answer: (A)

A network that provides wireless connectivity without the need for a centralized management point is known as an ad hoc network. In this type of network, devices communicate directly with each other without relying on a central access point or router. This self-organizing characteristic allows users to easily connect devices, such as laptops or smartphones, in a decentralized manner, making it particularly useful for temporary setups, such as during collaborative work or in situations where traditional network infrastructure is not feasible.

In contrast, other types of networks typically rely on centralized management. A mesh network, for instance, does have multiple connection points and can involve decentralized routing, but it is generally designed to provide more reliable coverage and redundancy through interconnected nodes, often with managed elements. An infrastructure network is the most common type of network, which utilizes a central management point, such as a router or switch, to connect devices. A point-to-point network specifically refers to a direct connection between two devices, which does not apply to the concept of wireless connectivity as a larger network type.

Understanding the distinction between these different types of networks helps clarify why an ad hoc network is defined by its lack of centralized management and direct connectivity between devices.
