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)

type of address requires manual configuration of the actual
network device or system and can be changed only manually or
by enabling DHCP.

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
