Applications on the Intenet

Telnet -- One of the earliest applications, it comes with its own terminal which allows remote logging. It's a Client/Server type. You can log into machines far away. It's traditional to have an account called guest or anonymous sot it's opened to anyone. There's a limit on how many people can use it at a time. It was first set up in colleges because they gave away their stuff for free.

FTP -- File Transfer Protocal; It's also Client/Server so you need an ftp sever on one machine and an ftp client on another machine. You can transfer files from one place to another. Its used to distribute software. There are several central ftp sites that allow people to deposit programs so that anyone could access them. Since so many people logged on at a time, they made a mirror ftp site which makes the exact copies of ftp servers so there's room for more people.

USENET -- a) Early Unix Internet gave rise to non- moderated lists. b) Bitnet - gave rise to moderated lists. All these concepts are bulletin board systems for others to read and write. In a non-moderated list, people have no control over what goes on the bulletin. You can subscribe to certain things. Moderated lists are like magazines where there's an editor that decides and arranges what can and cannot go onto the Internet. Moderated and non-moderated lists combined make up USENET.
