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 |
| applications for the Internet, Intranet and other complex, |
| distributed network. |

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, that |
| makes 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 |
| information from the Internet, the requests are forwarded to the |
| Internet under the router's IP address. NAT distributes the |
| responses to the proper IP addresses within your network. |
Network | A network consists of a collection of two or more devices, people, |
| or components that communicate with each other over physical or |
| virtual media. The most common types of network are: |
| LAN – (local area network): Computers are in close distance to |
| one another. They are usually in the same office space, room, or |
| building. |
| WAN – (wide area network): The computers are in different |

geographic locations and are connected by telephone lines or radio waves.
NWay Protocol A network protocol that can automatically negotiate the highest possible transmission speed between two devices.
P
PING | Packet Internet Groper, a utility used to determine whether a |
| specific IP address is accessible. It functions by sending a packet |
| to the specified address and waits for a reply. It is primarily used |
| to troubleshoot Internet connections. |
PPPoE | |
| connecting the users on an Ethernet to the Internet through a |
| common broadband medium, such as DSL or cable modem. All |
| the users over the Ethernet share a common connection. |
Protocol | Communication on the network is governed by sets of rules called |
| protocols. Protocols provide the guidelines devices use to |
| communicate with each other, and thus they have different |
| functions. Some protocols are responsible for formatting and |
| presenting and presenting data that will be transferred from file |
| server memory to the file server’s net work adapter Others are |
| responsible for filtering information between networks and |
| forwarding data to its destination. Still other protocols dictate how |
| data is transferred across the medium, and how servers respond to |
| workstation requests and vice versa. Common network protocols |
| responsible for the presentation and formatting of data for a |
| network operating system are the Internetwork Packet Exchange |
| (IPX) protocol or the Internet Protocol (IP). Protocols that dictate |
| the format of data for transferors the medium include token- |
| passing and Carrier Sense Multiple Access with Collision |
| Detection (CSMA/CD),implemented as |
| FDDI, or Ethernet. The Router Information Protocol (RIP),a part |
