Asymmetric Digital Subscriber Line. Communication technique that allows the transmission and reception of digital data over the copper pair of the switched telephone line, independently from the telephone service. The system is called "asymmetric" because the flow is greater in the downlink transmission from the network to the subscriber as in the uplink (stemming from the subscriber).
The bandwidth is the maximum amount of data that a communication channel is able to transmit per second. It is calculated in bits per second (bit/s) i.e. by using a unit that measures both throughput and speed of data transmission. Bandwidth can be an indication of speed and throughput.

Internet Protocol. Telecommunications protocol used on networks that support the Internet and divides the information into packets to be transmitted, to transmit the various packages, transport them independently of each other and reconstruct the incoming original message. This protocol uses a so-called packet switching technique. On the Internet, it is associated with a so-called Data Transmission Control Protocol called TCP, hence the term TCP/IP.
