Wi-Fi: • Wi-Fi is the wireless communication technology which is capable to support high speed internet and network connections. • It uses radio frequencies to connect sender and receiver without any wires. • It transfers the data at the rate of 11 Mbps (Mega bits per second), and 2.4 GHz (Giga Hertz). • IEEE 802.11b protocol is otherwise called as Wi-Fi (Wireless Fidelity). • Modern laptops and other handheld devices are enabled with Wi-Fi, the users can find the Wi-Fi hotspots and can be connected using wireless routers. CSMA/CA: Carrier sense multiple access with collision avoidance (CSMA/CA) is a media access control protocol or method used to avoid collisions by beginning transmission only after the channel is sensed to be idle.
