IDT networking vocabulary

Computer network

• technologies connect many devices that are relatively close to each other

• group of computers connected together  and communicate with one another

• anything that is connected to network

• a type of network in which each workstation has equivalent capabilities and responsibilities. Generally simpler but usually doesn't offer the same performance under heavy loads 

packet

• Part of a message that is transmitted over a network

• a type of network in which each workstation has equivalent capabilities and responsibilities. Generally simpler but usually doesn't offer the same performance under heavy loads 

• an agreed-upon format for transmitting data between two devices. Determines the type of error checking to be used, data compression method, how the sending device will indicate that has fini

• some computers are dedicated to searching other machines in the system. 

Node

•  an alphanumeric label assigned to computers and other devices that connect to a network using an internet protocol 

• A computer or other electronic device connected to a network

•  a type of network in which each workstation has equivalent capabilities and responsibilities. G

• an agreed-upon format for transmitting data between two devices. Determines the type of error checking to be used, data compression method, how the sending device will indicate that has finished sending a message, how the receiving device will indicate that it has received a message

Media Access Control (MSC)

•  each node is connected to a central device called a hub.

•  combines characteristics of a linear bus and star topologies

• the physical address of any device 

•  a type of network in which each workstation has equivalent capabilities and responsibilities.

Bus Topology

•  A network topology where each node is daisy-chained along the same backbone, similar to christmas lights

• have the nodes daisy chained but the difference is that the end of the network comes back around to the first node, creating a complete circuit 

• each node is connected to a central device called a hub. The hub takes a signal that comes from any node and passes it along to all the other nodes in the network

• combines characteristics of a linear bus and star topologies. It consists of groups of stars-configured workstations connected to a linear  backbone 

Ring Topology

• A network topology where each node is daisy chained together where the end of the network comes back around to the first node, forming a complete circle

• combines characteristics of a linear bus and star topologies. It consists of groups of stars-configured workstations connected to a linear  backbone 

• each node is connected to a central device called a hub. The hub takes a signal that comes from any node and passes it along to all the other nodes in the networkeach node is daisy chained (connected one right after the other) along the same backbone

• each node is daisy chained (connected one right after the other) along the same backbone

Network Token

• some computers are dedicated to searching other machines in the system

• a type of network in which each workstation has equivalent capabilities and responsibilities

• Determines the type of error checking to be used

• - a special series of bits that travels around a token-ring network.enabling its owners to send message across the network

Star Topology

• - each node is daisy chained (connected one right after the other) along the same backbone

• the nodes daisy chained but the difference is that the end of the network comes back around to the first node, creating a complete circuit

• A network topology where each node is connected to a central device or hub

• combines characteristics of a linear bus and star topologies. It consists of groups of stars-configured workstations connected to a linear bis backbone

Tree Topology

• each node is connected to a central device called a hub. The hub takes a signal that comes from any node and passes it along to all the other nodes in the network

• n - a special series of bits that travels around a token-ring network.enabling its owners to send message across the network

• some computers are dedicated to searching other machines in the system.

• combines characteristics of a linear bus and star topologies. It consists of groups of stars-configured workstations connected to a linear bis backbone

Protocol

• layer 1 device according to the Open system interconnection (OSI) reference model. Signifies that they operate solely at the physical later, as opposed to a software application

• some computers are dedicated to searching other machines in the system.

• An agreed upon format for transmitting data between two devices.

• a type of wire that consists of a center wire surrounded by insulation and then grounded shield of braided wire. The shield minimizes electrical and radio frequency interference
