Answer:
1 - WI - FI :
Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smart phones and wearables), and other equipment (printers and video cameras) to interface with the Internet. It allows these devices--and many more--to exchange information with one another, creating a network.
2 - Modem :
The word modem is a combination of the words “modulation” and “demodulation.” It goes back to the times when modems converted analog signals from telephone lines to turn them into digital signals. Nowadays, more advanced technology is used to do the same thing. But the shorthand term modem stuck, and people continue to use it today.
3 - Switch :
A switch is a data link layer networking device which connects devices in a network and uses packet switching to send and receive data over the network.
4 - Router :
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node(place).
