IP address ISP J JAVA L LAN M MJPEG MPEG4 N NAT Network NWay Protocol P PCM PING PPPoE IP address is a 32-binary digit number that identifies each sender or receiver of information that is sent in packets across the Internet. For example 80.80.80.69 is an IP address. 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 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 multi-thread programming best for creating applets and applications for the Internet, Intranet and other complex, distributed network. 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. 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 is designed to enable transmission and reception of high-quality audio and video over the Internet and next-generation mobile telephones. 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. 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. A network protocol that can automatically negotiate the highest possible transmission speed between two devices. PCM (Pulse Code Modulation) is a technique for converting analog audio signals into digital form for transmission. 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. Point-to-Point Protocol over Ethernet. PPPoE is a specification for 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. - 49 -
