HEX | Short for hexadecimal, “HEX” refers to the |
| symbols: the numbers 0 to 9 and the letters A through 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 |

Internet address | To participate in Internet communications and on Internet |
| have an Internet address that identifies it to the other nodes. All Internet addresses are IP |
| addresses. |
IP | The 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 | An IP address is a |
| that is sent in packets across the Internet. For example, 80.80.80.69 is an IP address. It is the |
| closest thing the Internet has to telephone numbers. When you “call” that number, using any |
| connection method, you get connected to the computer that “owns” that IP address. |
ISP | Internet Service Provider. 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. |
