Port number is a preassigned address within a server that provides a direct route from the application to the Transport layer, or from the Transport layer to the application, of a TCP/IP system.

Static IP refers to an IP address that has been specifically (instead of dynamically; see DHCP earlier in this chapter) assigned to a device or system in a network configuration. This type of address requires manual configuration of the actual network device or system and can be changed only manually or by enabling DHCP.

Transmission Control Protocol/Internet Protocol (TCP/IP ) is the communication protocol (language) of the Internet. Computers and devices with direct access to the Internet are provided with a copy of the TCP/IP program to allow them to send and receive information in an understandable form.

Telnet is a utility available on most PCs that allows the computer system to communicate with one of its remote users/ clients. A user who wishes to access a remote system initiates a Telnet session, using the address of the remote client. The user may be prompted to provide a user name and password if the client is set up to require them.

URL encoding allows you to send information and commands to the unit to change its configuration or provide you with feedback.
