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 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).
