Network equipment – devices necessary for the operation of a computer network. Classification of network cards, their functions and characteristics; network adapter settings Modem. Digital signal processor; protocol and speed; stability and quality of work.

Equipment containing electronic circuits, receiving power from an electric network or other sources and performing the functions of amplification, signal conversion and others. This means the ability of such equipment to process the signal using special algorithms. Packet data transfer occurs in networks; each data packet also contains technical information: information about its source, purpose, information integrity, and others, which allow delivering the packet to its intended purpose. Active network equipment not only captures and transmits a signal, but also processes this technical information, redirecting and distributing incoming streams in accordance with algorithms built into the device’s memory.
