FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Wi-Fi (/ˈwaɪfaɪ/) is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.

Detailed explanation-2: -There are several standards of IEEE 802.11 WLANs. The prominent among them are 802.11, 802.11a, 802.11b, 802.11g, 802.11n and 802.11p. All the standards use carrier-sense multiple access with collision avoidance (CSMA/CA). Also, they have support for both centralised base station based as well as ad hoc networks.

Detailed explanation-3: -Wireless 802.11 Definition: 802.11 is a standard that was developed by the Institute of Electrical and Electronic Engineers (IEEE). It is the original wireless specification. Extensions of the 802.11 standard were given the same number with a letter suffix.

Detailed explanation-4: -802.11b (also referred to as 802.11 High Rate or Wi-Fi )–an extension to 802.11 that applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS.

Detailed explanation-5: -IEEE 802.11b: The 802.11b standard provides for a maximum transmission speed of 11Mbps. However, devices are designed to be backward-compatible with previous 802.11 standards that provided for speeds of 1, 2, and 5.5Mbps. 802.11b uses a 2.4GHz RF range and is compatible with 802.11g.
