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 networks. |
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, a network address translator 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 |
| networks are LANs and WANs. In a LAN (local area network), computers are in close distance |
| to one another. They are usually in the same office space, room, or building. In a WAN (wide |
| area network), the computers are in different geographic locations and are connected by telephone |
| lines or radio waves. |
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 | |
| Ethernet to the Internet through a common broadband medium, such as a DSL or cable modem. |
| All the users over the Ethernet share a common connection. |
