In the initial days, the routers were basically the way people would be able to connect to the internet. A WLAN is basically password protected, but may be kept open, which allows any kind of device within its range to access the resources of the WLAN network. Wi-Fi or WiFi, on the other hand, is basically a technology that allows the electronic devices to connect to a completely wireless LAN (or WLAN) network, which mainly uses the 2.4 gigahertz or 12 cm UHF and 5 gigahertz which is equivalent to 6 cm SHF ISM radio bands.
At first, it also connected a daisy chain, but later through the Ethernet hubs, which reflected all the traffic received on a port to other ports. It is known as a link layer protocol basically present in the TCP/IP stack, which describes the process of how connected devices can format the data with the aim of communication to other network devices located on that network segment.Įthernet was initially assumed to be a shared medium which had multiple devices in every part of the network. Ethernet is termed to be the widely installed LAN technology.
