device connected to the net and used for information interchange. (computer or a peripheral device)
Server is a net node providing its recourses to other stations. (They are Web-server, mail-server, FTP-server, NNTP-server, DNS-server.)
Client (work station) is a net node using net recourses.

![Point 2. The Main terms of Internet Internet is a global net](/_ipx/f_webp&q_80&fit_contain&s_1440x1080/imagesDir/jpg/375025/slide-7.jpg)
a common address space and using TCP/IP.
Protocol is a rule complex regulating the information exchange between stations.
TCP (Transmission control protocol) is a protocol handling the data delivering.
IP (Internet protocol) is a protocol used between nodes in the Internet.
