HEX Short for hexadecimal refers to the base-16 number system, which
consists of 16 unique symbols: the numbers 0 to 9 and the letters
A to F. For example, the decimal number 15 is represented as F in
the hexadecimal numbering system. The hexadecimal system is
useful because it can represent every byte (8 bits) as two consecutive
hexadecimal digits. It is easier for humans to read hexadecimal
numbers than binary numbers.

Intranet This is a private network, inside an organization or company, that
uses the same software you will find on the public Internet. The
only difference is that an Intranet is used for internal usage only.
Internet The Internet is a globally linked system of computers that are
logically connected based on the Internet Protocol (IP). The Internet
provides different ways to access private and public information
worldwide.
Internet address To participate in Internet communications and on Internet Protocol-
based networks, a node must have an Internet address that identifies
it to the other nodes. All Internet addresses are IP addresses
IP Internet Protocol is the standard that describes the layout of the basic
unit of information on the Internet (the packet) and also details the
numerical addressing format used to route the information. Your
Internet service provider controls the IP address of any device it
connects to the Internet. The IP addresses in your network must
conform to IP addressing rules. In smaller LANs, most people will
allow the DHCP function of a router or gateway to assign the IP
addresses on internal networks.
IP address IP address is a 32-binary digit number that identifies each sender or
receiver of information that is sent in packets across the Internet.
For example 80.80.80.69 is an IP address, it is the closet thing the
Internet has to telephone numbers. When you “call” that number,
using any connection methods, you get connected to the computer
that “owns” that IP address.
ISP Internet Service Provider, is a company that maintains a network
that is linked to the Internet by way of a dedicated communication
line. An ISP offers the use of its dedicated communication lines to
companies or individuals who can’t afford the high monthly cost for
a direct connection.
