Since mechanisms like Telnet and Remote Shell are designed to access and operate remote computers, sending the authentication tokens (e.g. username and password) for this access to these computers across a public network in an unsecured way poses a great risk of 3rd parties obtaining the password and achieving the same level of access to the ...
Users type in domain names, such as example.org, which the computer's DNS software looks up in the DNS databases to retrieve an IP address, and then hands off that address to the protocol stack for further communications. [5] Looking up an address using DNS requires the IP address of the DNS server to be known.

Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
A remote access service connects a client to a host computer, known as a remote access server. [1] The most common approach to this service is remote control of a computer by using another device which needs internet or any other network connection. Here are the connection steps: User dials into a PC at the office.

In other textbooks, [1] the term socket refers to a local socket address, i.e. a "combination of an IP address and a port number". In the original definition of socket given in RFC 147, [ 2 ] as it was related to the ARPA network in 1971, "the socket is specified as a 32-bit number with even sockets identifying receiving sockets and odd sockets ...
