Wireless Local Area Network Question & Answers December 27, 2022 By WatElectronics This article lists 100 Wireless Local Area Network MCQs for engineering students. All the 100 Wireless Local Area Network Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the Wireless Local Area Network. The wireless network of the computer can link more than two devices using communication i.e., wireless, and forms the Local Area Network (LAN). It is confined to school, home, any campus or laboratory, any office, and so on. Users in the such network can be able to move in that respective area staying connected. Using gateways, WLANs provide internet connections and make them wider. 'IEEE 802.11' is the most preferable standard in computer networking. It is commonly referred to as Wi-fi. Laptops, computers, smartphones, smart TVs, etc.… are linked together with a router provided i.e., wireless and it links the devices to provided internet. Routers provide hotspots at salons, hotels, airports, restaurants, and so on. This ensures that consumers get access to the internet via wireless portable devices. The components that get connected to wireless media in the network are known as stations. Wireless network interfacing controllers are present in the stations. Wireless stations are categorized as WAPs (Wireless Access Points) & clients. The base station to any network i.e., wireless is WAP. Wireless devices can be communicated by transmission & reception of Radio frequencies. Infrastructure and the Ad hoc are two operating modes of WLAN. Nowadays IOT paved the way to build connectivity that is advanced compared to wi-fi. 1).
