Ch 2 - Network Hardware 1
Because they operate by forwarding packets across all ports indiscriminately, these devices are sometimes referred to as "dumb switches."
What is a hub?
Command issued from the command prompt to test whether your computer has connectivity to the network.
What is ping?
UTP stands for . . .
What is unshielded twisted pair?
Interference caused by wires in the same cabling bundle.
What is cross talk?
This type of media has seen numerous iterations over the years.
What is copper cable?
Device that receives a frame and reads the source and destination MAC addresses before forwarding the frame out another port?
What is a switch?
MAC address are contained in this computer component.
What is a NIC?
The most common topology and technology combination in use today?
What is switched/ethernet?
Type of wiring used for a high-speed connection between two buildings.
What is fiber?
A disadvantage of using fiber-optic cabling versus twisted-pair cabling.
What is more expensive, difficult to terminate, difficult to test, limited bend radius.
What a switch does if it doesn't find the destination MAC address in its switching table.
What is forwarding the frame out all ports?
Devices on this network hardware have to share the available bandwidth.
What is a hub?
Topology that is fully redundant and is most expensive to implement.
What is mesh topology?
A free-standing or wall-mounted rack for managing and interconnecting a telecommunications cable between end-user devices and the main distribution frame (MDF)
What is an IDF (Intermediate Distribution Frame)?
An equipment and cabling room that serves as the connecting point for backbone cabling between buildings and between IDFs.
What is an MDF (Main Distribution Frame)?
Communication mode in which a device can send and receive signals but not at the same time.
What is half-duplex mode?
NIC mode that allows all frames through, so even frames intended for other machines or network devices can be read.
What is promiscuous mode?
Cyclic redundancy check is an error checking associated with . . .
What is a frame?
Runs from work area's jack to telecommunications closet
What is horizontal wiring?
The volume of information per unit of time that a transmission medium can handle.
What is bandwidth?
This type of frame is addressed to a specific computer.
What is a unicast.
Amount of data that can be transferred on a network in a specified interval.
What is network bandwidth?
When discussing Ethernet standards, the XBaseY terminology refers to . . .
What is the transmission speed, type of transmissions, and length or type of cabling
How bit signals are represented on medium.
What is encoding?
Cables are distinguished by two of these three characteristics.
What is type of signal, speed of signal and distance they can travel?
