Step-by-step explanation:
A Basic Service Set (BSS) in computer networking refers to the basic building block of a wireless LAN. It consists of a single access point (AP) and one or more wireless client devices, such as laptops, smartphones, or tablets.
The AP acts as a central hub, connecting the client devices to the wireless network. It manages the transmission of data between devices within its coverage area. The BSS can be either an Independent BSS (IBSS) where devices communicate directly with each other, or an Infrastructure BSS (IBSS) where devices communicate through the AP.
For example, in a home Wi-Fi network, the Wi-Fi router acts as the AP, and the devices such as laptops and smartphones connect to it to access the internet.
