Set of hardware, software, and media systems used to connect computers together
What is a network?
100
Data communication system consisting of multiple devices such as computers and printers.
What is (LAN)?
100
Processing location that can be a PC or some other device such as a networked printer
What is media?
100
Data moves though the network in a structure which are pieces of a message broken down into small units by the sending PC and reassembled by the receiving PC.
What are packets?
100
The device at each node that performs translation and transmission.
What is a network interface card (NIC)?
200
An agreement to buy a single copy of a program and then pay the software developer a fee for the right to copy the application onto a specified number of computers
What is a site license?
200
Connection of two or more central computers or LANs, generally across a wide geographical area.
What is Wide Area Network?
200
Normally consists of four pairs of wires. The individual pairs have two wires that are separately insulated in plastic, then twisted around each other and bound together in a layer of plastic.
What is twisted pair?
200
The logical layout of the cables and devices that connect the nodes of the network.
What is topology?
200
Provides multiple ports for connecting nodes. When it receives a packet from one port, it transmits the packet without modification to all the other nodes.
What is a hub?
300
Electronic mail, real-time chat program, social media, business conferencing.
What are examples networks connect people?
300
An internal version of the Internet.
What is intranet?
300
Thin strand of glass that transmits pulsating beams of light rather than electric current.
What is fiber-optic cable?
300
Bus, star, ring and mesh?
What are examples of topologies?
300
Looks at each packet's header to determine where the packet should go and then determines the best route for the packet to take toward its destination.
What is a router?
400
Method of efficiently and reliably transmitting voice across a computer network, turning a computer into a telephone.
What is VoIP?
400
Share some of its intranet resources with people outside the organization.
What is extranet?
400
Computers are now commonly equipped with an antenna and transmitter for connecting to LANs and public Internet access points.
What is wireless hotspots?
400
A special device, attached at the cable's start and end points, to stop network signals so they do not bounce back down the cable.
What is a terminator?
400
It can allow multiple conversations between nodes to take place simultaneously (for example, two computers can deliver data to each other while two different computers do the same), because it can keep the packet flow of each conversation separate.
What is a switch?
500
Allow one user to access another user's PC as if it were his or her own.
What is PC sharing?
500
Twisted pair, coaxial and fiber-optic cable
What are examples of network media?
500
The amount of data over time that the media can carry, typically measured in either megabits per second (Mbps) or gigabits per second (Gbps).
What is bandwidth?
500
Actual data being transmitted between the two nodes.
What is payload?
500
Create a connection between different types of networks, and a node on a network that serves as an entrance to another network.
