What type of network device is primarily responsible for providing wireless connectivity?

The primary device responsible for providing wireless connectivity in a network is the Wireless Access Point (WAP). A WAP serves as a bridge between wired networks and wireless devices, allowing laptops, smartphones, and other handheld devices to connect to the network without physical cables. It broadcasts radio signals that users can connect to, facilitating communication between these devices and the wired network infrastructure.

While routers can also provide wireless connectivity by integrating a WAP within their functionality, they have additional roles, such as directing traffic between different networks and managing local network settings. Switches are designed to manage network traffic between wired devices and do not inherently provide wireless capabilities. Firewalls are primarily used for security tasks, such as monitoring and controlling incoming and outgoing network traffic, rather than for enabling wireless connectivity.

Thus, the Wireless Access Point is specially designed for this purpose, making it the correct choice for providing wireless connectivity.
