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.
