J
JAVA
Java is a programming language that is specially designed for wr
iting 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.
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 high-quality audio and
video over the Internet and next-generation mobile telephones.
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
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.
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
