The Internet is connected in one of two ways:


Wired connection: This uses cables to provide a wired connection to the Internet through the network port on the computer, depending on the phone line.

Wireless connection: This uses Wi-Fi technology to provide wireless communication, and it uses radio waves to exchange information through computer networks.

The icon for wireless communication indicates the strength of the transmitter through the colors of the outgoing waves that appear in the image, where the gray color expresses the weakness of the signal, while all waves become colored to indicate the strength of the transmitter.

The wired connection is faster and stronger than the wireless connection usually, as the wireless connection depends on the strength of the broadcast, and therefore its speed, on its distance from the access point of the network. It is possible to access the Internet using the mobile phone, and this is different from using the network to make a phone call.
