An access point is a device that allows wireless devices to connect to a wired network using Wi-Fi. It acts as a central transmitter and receiver of wireless radio signals, enabling devices such as laptops, smartphones, and tablets to join a network without requiring physical cables.
Access points are primarily used to extend the reach of a wired network, providing wireless connectivity to devices within a specific area. They enhance network flexibility and scalability by allowing more devices to connect simultaneously, thereby supporting increased user mobility and productivity in homes, offices, and public spaces.
The main difference between a router and an access point lies in their functions and scope within a network. A router is a networking device that forwards data packets between computer networks, manages traffic, and serves as the gateway to the internet for connected devices. In contrast, an access point simply provides a wireless connection point for devices to join a network, typically extending the coverage of an existing wired network.
An access point is defined as a networking hardware device that enables Wi-Fi devices to connect to a wired network using wireless communication. It facilitates wireless connectivity by transmitting and receiving data between Wi-Fi devices and the wired network infrastructure.
An example of an access point is a wireless router commonly found in homes and small offices. These devices typically combine the functions of a router and an access point, allowing users to connect their devices wirelessly to the internet while also managing traffic between connected devices and external networks.
