A wireless local area network (WLAN) is a type of computer network that uses wireless communication technologies instead of traditional wired connections. There are several synonyms for WLAN, including Wi-Fi network, wireless LAN, wireless network, 802.11 network, and Wi-Fi hotspot. These phrases all refer to the same type of network, with the only difference being the terminology used. Wi-Fi is perhaps the most commonly used term, as it is used by many modern devices to connect to the internet. Regardless of the term used, WLANs are becoming increasingly popular in both the home and workplace due to their ability to provide fast and reliable wireless connections.
