The arrangement of nodes in a network environment.
What is a topology?
100
When a metal wire encounters a magnetic field.
What is EMI?
100
This network equipment serves as the interface between the PC and the computer.
What is a NIC?
100
This access method listens to the network before transmitting a packet?
What is CSMA/CD?
200
This layer identifies devices on the devices on the Physical layer. This layer controls the transmission, reception, and addressing of frames. MAC addresses are a part of this layer and Bridges operate here as well.
What is Data-link layer?
200
The computers in this topology are connected in a single line. This topology uses terminators to prevent signal reflection.
What is bus topology?
200
The 2 most common types of cable used in a network environments today.
What is twisted-pair and fiber optic?
200
This hardware device connects to multiple devices and send signals to all nodes. Are rare, being replaced by switches.
What is a hub?
200
A NIC will send FF-FF-FF-FF-FF-FF onto the network if the NIC doesn't know the destination MAC address.
What is a broadcast address?
300
This layer breaks data into manageable chunks. TCP, UDP, SPX, and NetBEUI operate at this layer.
What is Transport layer?
300
This topology has a central device, such as a hub, and each node is connected to it. This topology is also the most prevalent.
What is a star topology?
300
This common cable carries an electrical signal and consists of a pair of wires that are wrapped to reduce crosstalk.
What is twisted-pair cable?
300
This hardware device connects to multiple devices, but only sends to the system that the packet is intended for.
What is a switch?
300
Another name for the MAC address.
What is a phyiscal address?
400
This layer moves packets between computers on different networks. Routers operate at this layer. IP and IPX operate at this layer.
What is the Network layer?
400
This topology is similar to the bus topology, but the 2 ends are connected.
What is a ring topology?
400
This common cable carries a light signal.
What is fiber optic cable.
400
Use this device to interconnect 2 different types of cable-used in Ethernet networks.
What is media converter?
400
The space above the false ceiling and the floor or roof above it. Is also a fire rating for network cabling.
What is the pelmum?
500
This layer defines hardware connections and turns binary into physical pulses (electrical or light). Repeaters or hubs operate at this layer.
What is the Physical layer?
500
In this topology, each computer has a direct, dedicated connection to every other computer. This topology is also the most fault-tolerant.
What is a mesh topology?
500
The maximum amount of data that goes through the cable per second.
What is bandwidth?
500
This hardware device connects 2 separate networks and forwards a packet from 1 network to another based on the network address for the protocol being used. An IP router looks only at the IP address. Operates at layer 3 of the OSI model.
What is a router?
500
The capability of any system to continue functioning after some part of the system has failed.
