HEX | Short for hexadecimal refers to the |
| 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, which 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 |
| 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 |
| 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. |

JAVA | Java is a programming language that is specially designed for writing programs that can be safely |
| downloaded to your computer through the Internet without the fear of viruses. It is an object- |
| oriented |
| Intranet and other complex, distributed network. |
L
LAN | Local Area Network a computer network that spans a relatively small area sharing common |
| resources. Most LANs are confined to a single building or group of buildings. |
N
NAT | Network Address Translator generally applied by a router, making many different IP addresses |
| on an internal network appear to the Internet as a single address. For routing messages properly |
| within your network, each device requires a unique IP address. But the addresses may not be |
| valid outside your network. NAT solves the problem. When devices within your network request |
