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 |
| applications for the Internet, 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. |
M
MJPEG | MJPEG (Motion JPEG) composes a moving image by storing each frame of a moving |
| picture sequence in JPEG compression, and then decompressing and displaying each |
| frame at rapid speed to show the moving picture. |
MPEG4 | MPEG4 is designed to enable transmission and reception of |
| video over the Internet and |
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
PCM | PCM (Pulse Code Modulation) is a technique for converting analog audio signals into |
| digital form for transmission. |
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 | |
| 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 |
