TTY - Posted by Robert Bell.
In the early days of Unix, teletypewriters or ttys were used by users to communicate over a serial line with the mainframe computer. The mainframe had no keyboard or monitor as it has now and so during those early days, all commands were issued through the tty. The output of the commands was typed on the printer that was part of the tty. The tty terminals had no processing power of their own and hence were known as “dumb” terminals.

Choose one among them depending on what you want.
A proxy server protects your privacy by being the ‘middleman’ between you and a real server. When you visit a website, it intercepts your requests to determine if it can manage your requests by itself. If it can’t take care of your request, the proxy server will send the request to the real server. Thus, it provides you with indirect access to real servers.

DSL (Digital Subscriber Line) is a telecommunication service that transforms an ordinary phone into a high-speed conduit for data, voice and video.
