Wifi

 Wi-Fi is a wireless local area network (LAN) technology that enables electronic devices to network together.

Wi-Fi   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. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide the public Internet access for mobile devices.

What is Wi-Fi IEEE 802.11?

Wi-Fi is officially designated for IEEE 802.11. The Wi-Fi Alliance certifies that network equipment conforms to the IEEE 802.11 standard.

Types of Wi-Fi Adapters

Wi-Fi comes in a variety of forms. Some Wi-Fi technology is built into such as smart phones, laptops, game consoles, modern printers and scanners, but personal computers do not have built-in Wi-Fi technology because the personal computer design network. Ready to connect via wire but we both use Wi-Fi for personal computers comes in two types, one is internal and the other is external.

The internal Wi-Fi we put in the PC slot and the external Wi-Fi comes with a small stick that we plug into the USB.

Access points

Usually we use the router to connect wireless devices to each other and we can easily access other devices that are connected to the router through a network cable. Access points (APs) are used to connect both wireless and wireless devices to wireless devices.

Hotspot point

The Hotpot has a maximum range of 20 meters (about 66 feet) indoors and has a longer and longer range outdoors. Hotspots are blocked by radio wave walls or reduce the signal strength or in the outdoor we get many kilometers over overlapping access points.
