WLAN stands for Wireless Local Area Network. It is a wireless network that allows devices to connect and communicate within a limited area, such as a home, office, or campus. WLAN uses radio waves to transmit data between devices, eliminating the need for physical cables. This technology enables users to access the internet and share resources, such as files and printers, without being physically connected to a network.

WLAN (Wireless Local Area Network) powers the internet. WLAN is a wireless network technology that allows devices to connect to the internet without the need for physical cables. It provides wireless access to the internet, enabling users to browse websites, access web applications, use search engines, and connect to social media platforms. WLAN powers the internet by providing a wireless connection to devices, allowing them to access and utilize the vast resources and services available on the internet.

WLAN hotspots are wireless networks that allow devices to connect to the internet. They typically require registration, as users need to provide their personal information to gain access. They also usually require a password for security purposes. Additionally, while many WLAN hotspots are free, some may require payment for usage. However, one feature that is not typically associated with WLAN hotspots is that they do not require a mobile station. A mobile station refers to a device, such as a smartphone or tablet, that connects to the hotspot. Therefore, the correct answer is "It does not require mobile station."

Wifi is the most popular local area network technology because it allows devices to connect to the internet or communicate with each other wirelessly. It is widely used in homes, offices, and public spaces due to its convenience and accessibility. Wifi technology enables multiple devices to connect simultaneously, providing high-speed internet access and seamless connectivity. It has become the preferred choice for internet connectivity due to its widespread adoption and compatibility with various devices.

ALOHAnet is considered the first wireless local area network (WLAN) because it was developed in the 1970s as a radio network at the University of Hawaii. It allowed multiple computers to connect and communicate wirelessly, pioneering the concept of shared wireless communication. ALOHAnet laid the foundation for future WLAN technologies and protocols, making it the first of its kind.

ARCNET, Token Ring, and Apple Talk are all historical networking technologies that were used in the past. Telly Ring, however, is not a known historical technology and may not have existed or been widely used.

IEEE 802.11 has two basic modes of operation: infrastructure mode and ad hoc mode. In infrastructure mode, devices communicate through an access point, while in ad hoc mode, devices communicate directly with each other without the need for an access point. These two modes provide flexibility in establishing wireless networks based on different requirements and scenarios.

Wifi Direct Network is the correct answer because it enables communication between stations without the need for an access point. It allows devices to connect directly to each other and share data, making it a convenient feature for peer-to-peer communication. Unlike traditional Wifi networks that require an access point, Wifi Direct Network allows devices to establish a direct connection, making it suitable for scenarios where internet access is not available or necessary.

The function of the bridge in wireless connections is to serve as a connection point. It acts as a link between two different networks, allowing devices connected to one network to communicate with devices on the other network. The bridge receives data from one network and transmits it to the other network, enabling seamless communication between the two networks.

The Cambridge Ring was developed in 1974.
