Communication Communication has four component s: sender, receiver,
message, and medium. In networks, devices and application tasks and processes communi cate messages to each other over media. They represent the sender and receivers. The data they s en d is the message. The cabling or tra nsmission method they use is the medium.
Connection In networking, two devices establish a connection to
communicate with each other.
D
DHCP Developed by Microsoft, DHCP (Dy nam ic Hos t
Configuratio n P r otocol) is a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can even change while it is still connected. It also supports a mix of static and dynamic IP addresses. This simplifies the task for network administrators because the software keeps track of IP addresses rather than requiring an administrator to manage the task. A new computer can be added to a network without the hassle of manually assigning it a unique IP address. DHCP allows the specification for the service provided by a router, gateway, or other network device that automatically assigns an IP address to any device that request s one .
DNS Domain Name System is an Internet service that
translates domain names into IP addresses. Since domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses every time you use a domain name the DNS will translate the name into the corresponding IP address. For example, the domain name
www.network_camera.com might translate to
192.167.222.8.

Enterprise network
An enterprise network consists of collections of networks connected to each other over a geographically dispersed area. The enterprise network serves the needs of a widely distributed company and operates the company’s mission-critical applications.
Ethernet The most popular LAN co mmunication technology. There
are a variety of types of Ethernet, including 10Mbps (traditional Ethernet), 100Mbps (Fast Ethernet), and 1,000Mbps (Gigabit Ethernet). Most Ethernet networks use Category 5 cabling to carry information, in the form of electrical signals, between devices. Ethernet is an implementation of CSMA/CD that operates in a bus or star topology.
F
Fast Ethernet Fast Ethernet, also called 100BASE-T, operates at 10 or
100Mbps per second over UTP, STP, or fiber-optic media.
Firewall Firewall is considered the first line of defense in
protecting private information. For better security, data can be encrypted. A system designed to prevent unauthorized access to or from a private network. Firewalls are frequently used to prevent unauthorized Internet users from acc essing private networks connected to the Internet, especially Intranets all messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
G
Gateway A gateway links computers that use different data
formats together.
Group Groups consist of several user machines that have
similar characteristics such as being in the same department.

H
HEX Short for hexadecimal ref e rs to th e base-16 number
system, which consists of 16 unique symbols: the numbers 0 to 9 and the letters A to F. For example, the decimal number 15 is represented as F in the hexadecimal numbering system. The hex adecimal system is useful bec ause it can represent every byte (8 bits) as two consecutive hexadecimal digits. It is easier for humans to read hexadecimal numbers than binary numbers.
I
Intranet This is a private network, insi de an organization or
company that uses the same software you will find on the public Internet. The only difference is that an Intranet is used for internal usage only.
Internet The Internet is a globally linked system of computers that
are logically connected based on the Internet Protocol (IP). The Internet provides different ways to access private and public information worldwide.
Internet address To participate in Internet communications and on Internet
Protocol-based networks, a node must hav e an Internet address that identifies it to the other nodes. All Internet addresses are IP addresses
IP Internet Protocol is the standard that describes the layout
of the basic unit of information on the Internet (the packet) and also details the numerical addressing format used to route the information. Your Internet service provider controls the IP address of any device it connects to the Internet. The IP addresses in your network must conform to IP addressing rules. In smaller LANs, most people will allow the DHCP function of a router or gateway to assign the IP addresses on internal networks.
IP address IP address is a 32-binary digit number that identifies
each sender or receiver of information that is sent in packets across the Inte rnet. 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 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.
J
JAVA Java is a programming language that is specially
designed for writin g programs that can be safely downloaded to your computer through the Internet without the fear of viruses. It is an object-oriented multi­thread 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 prop erly 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 E t her net. 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 connec t io n.

Protocol Communication on th e 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 network s and forwarding data to its destination. Still other protocols dictate how data is transferred across the m ediu m , an d h ow serv er s 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 Detection (CSMA/CD), implemented as token-ring, ARCNET, FDDI, or Ethernet. The Router Information Protocol (RIP),a part of the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, forwards packets from one network to another using the same network protocol.
R
RJ-45 RJ-45 connector is used for Ethernet cable connections. Router A router is the network software or hardware entity
charged with routing packets between networks.
RTP RTP (Real-time Transport Protocol) is a data transfer
protocol defined to deliver live media to the clients at the same time, which defines the transmission of video and audio files in real time for Internet applications.
RTSP RTSP (Real-time Streaming Protocol) is the standard
used to transmit stored media to the client(s) at the same time, which provides client controls for random access to the conten t stream.

mail.
SNMP Simple Network Management Protocol. SNMP was
designed to provide a common foundation for managing network devices.
Station In LANs, a station consists of a device that can
communicate data on the ne twork. In FDDI, a station includes both physical nodes and addressable logical devices. Workstations, single-attach stations, dual-attach stations, and concentrators are FDDI stations.
Subnet mask In TCP/IP, the bits used to create the subnet are called
the subnet mask.
T
(TCP/IP) Transmission Control Protocol/Internet Protocol is a
widely used transport protocol that connects diverse computers of various transmission methods. It was developed y the Department of Defense to connect different computer types and led to the development of the Internet.
Transceiver A transceiver joins two network segments together.
Transceivers can also be used to join a segment that uses one medium to a segment that uses a different medium. On a 10BASE-5 network, the transceiver connects the network adapter or other network device to the medium. Transceivers also can be used on 10BASE­2 or 10BASE-T networks to attach devices with AUI ports.
