1.
IEEE: Also known as the Institute of Electrical and Elcectronics Engineers. It is an international non-profit, professional organization that works on the advancement of technology related to electricity.
2.
IEEE 802.3: Several IEEE standards that define the physical layer, as well as the media access control (MAC) sublayerof the data link layer, of wired Ethernet. Various types of copper or fiber cable make physical connections between nodes and/or infrastructure devices such as hubs, switches and routers.
3.
Ethernet: It defines several wiring and signaling standards for the physical layer,though network access at the Media Acess Control(MAC)/Dataa Link Layer, and a common addressing format. It has a series of frame-based computer networking technologies for local area networks (LANs).
4.
Star Topology: Consists of one central switch, hub or computer, that transmits messages to the other parts o the network. It is one of the most common co puter network topologies.
5.
Hub: A device for connecting many twisted pair or fiber optic Ethernet devices together. This making them act as a sigle segment. These such hubs work at the physical layer of the OSI model. They are also responsible for forwarding a jam signal to all ports if it detects a collision.
6.
Proxy Server: A porxy server is a server, in computer networks, which serves the requests of its clients by forwarding requests to other servers. The proxy server connects to a specifieed server and requests the service needed on behalf of the client.
7.
Collision: in networking, it is when more than one computers or networking devices attempt to send data at the same time to one computer, server or other network device.
8.
Firewall: It is a system that protects networks from unauthorized users and viruses, and can be used in hardware and/or software. Firewall can also control the amount of datat that leaves a network.
9.
Protocol: It enables/controls the connection, communication and data transfer between two computing systems. It can also be referred to as a set of rules for communication. It can be used for both software and hardware, or both togethe. A protocol defines the behavior of a hardware connection.
10.
Broadcast Domain: It is a logical network segment which in any devices connected to a netwrok can transmit directly to any other on the domain without having to go through a routing device. This is provided that they share the same subnet address and are in the same VLAN, default or installed.
11.
Intranet: A private computer network that uses Internet protocols, and network connectivity to securelt share part of an organization 's information or operations with its fellow members. The term sometimes only refers to the most visible part of the service, the intranet website.
12.
NIC: Stands for netwrok interface card. It is a piece of computer hardware that is designed to allow computers to communicate over a computer network. It is a device that works on the physical layer and the data link layer. This is due to the fact that it provides physical access to a netwroking medium and provides a low-level addressing system through the use of MAC addresses. It allows uses to conect to each other weither by using cables or wirelessly.
13.
Router: It is a device that extracts a packet's destination that it receies, and then selects the best path for it to get to that destination. Therefore it forwards the data packets to the next device along this best chosen path. They are used to connect networks together so as to be able to connect to the internet.
14.
Router: It is a device that attaches to the end-points of a bus network or daisy chain. It's purpose is to absorb signals so that they do not reflect back down the line. Ethernet netwroks and SCSI chains are some examples of things that require a terminator.
15.
Plenum Cable: They are placed in the plenum spaces of a building. It is astiffer and stronger cable than a network cable.
16.
Block coding: It is a type of channel coding that adds to a message so that the receiver can decode it with a minimual amount of error.
17.
Plenum:It is the space in a bulding that is used for heating, ventillating, or airconditioning equiptment. This space is also where plenum cables are placed.
18.
MAC Address: In computing networking it is a quasi-unique identifier attached to most network adapters (NIC). it is a number that acts as name for a particular network adapter.
19.
Bridge: Filters data at a network boundary. It connects multiple network segments at the data link layer. Bridges are like repeaters or network hubs, as they connect network segments at the physical layer. Te difference between these devices is that the bridge manages data rather than just rebroadcast it.
20.
Point To Point Technology: When information is transferred from one point to another.
21.
Late Collision: A type of collision that occurs in CSMA/CD protocol standard. If the collision error happens after the initial 512 bits of data are transmitted, then the collicion is considered to be a late collision. More importantly, late collisions are not re-sent by the NIC, but instead left for the upper layers of the upper layers of the protocol stack to determine that the there was a loss of data.
22.
MAU (Multiple Access Unit): is a device that attaches multiple network stations in a satar topology in a token ring network. It is internally wired to conect the stations into a logical ring.
23.
Full Duplex Operation: Allows data to be sent both directions simultaneously in a connection between two devices. Full-duplex channels can be constructed either as a pair of simplex links or using one channel designed to permit bidirectional simultaneous transmissions. This sort of connection can only connect two devices, so many of these links are needed if multiple devices are attached together.
24.
Half-Duplex Operation: Is capable of sending information in both directions between two nodes, but only one direction or the other can be utilized at a time. Any device in a conventional Ethernet networks, any device can transmit, but only one may dp so at a time.
25.
Baud: It is a measure of the symbol rate, thenumber of distinct symbol changes made to the transmission medium per second in a digitally modulated signal.
26.
Bit Rate: The number of bits that are processed or conveyed in a unit of time. It can be related to netwrokiung through the speed of the network , and how many bits are processed per second.
27.
Link Integrity Test: MAUs continously monitor the receive data path for activity as a means of checking that the link is working properly. When the network is idle, the MAUs also send a link test signal to one another to verify link integrity. There are link lights at each end that are lit. This is important as it shows that there is a properly wired signal path between both devices.
28.
10Base (Generic): The most commonly used number system.Each number has a base of 10. It is also known as the decimal numeral system.
29.
100Base (generic): It is when a fast ethernet is going at 100Mbits/s.
30.
LLC (library link code): It is the codes that a library puts on its website for people to have easier access to other links quickly.
31.
AUI: Also known as an Attachment Unit Interface. It is a 15 pin connection that provides a path between a node's Ethernet interface and the MAU, alos known as a transceiver.
32.
Packet: Discreet blocks of data. Data is seperated into these 'packets' so that instead of all the data that is being tranfered being corrupted and having to resend all the data again. Instead the packet that was corrupted or misplaced can be resent.
33.
Bandwidth: It is the difference between the upper and lowercutoff frequencies of filters, a communication channel, ora signal spectrum, for a few examples. It is typically measured in hertz. Digital bandwidth refers to the data transfer rate measured in bits/s.
34.
Repeater: Is an electronic device that receives a signal and retransmits it at a higher level or a higher power. It can also be retransmitted onto the other side of an obstruction, so that the signal can cover a longer distance without degradation.
35.
Octet: A group of eight bits, often referred to as a byte. They are often used in networks.
36.
Port: In the TCP and UDP protocols is a special number that is present in the header of a data packet. They are mainly used to mapdata to a particular process running o a computer.
37.
Transmission Control Protocol (TCP): Is one of the core protocols of the Internet protocol suite. TCP gives reliable. in-order delivery of a stream of bytes, making it suitable for applications like file transfer and e-mail.
38.
Internet Protocol (IP): It is a data-oriented protocol used for communicating data across a packet-switched internetwork. IP is a network layer protocol that can be found in the Internet protocol suite and is encapsulated in a data link layer protocol. IP provides the service oc communicable unique global addressing amongst computers.
39.
File Transfer Protocol (FTP): It is used to transfer to transfer data from one computer to another through a network or over the internet. It is most commonly used protocol for exchanging files over netwoks that support the TCP/IP protocol. In this tranfer there is two computers the server and the client. The server listens on the network for connection requests from other computers. The client computerindicates a connection to the server. Once they are connected the client can do many file manipulation operations such as uploading and downloading files.
40.
Logical address: It is a logical address which a memory location appears to reside from the perspective of an executing application program.
41.
Domain Name Service (DNS): It is associated with various kinds of information with si-called domain names; but more importantly it serves as a phone book for the Internet by translating human-readable host names into IP addresses, that networking equiptment needs to deliver information. This system is an essential component of contemporary Internet use.
