A network card provides the capability to communicate with other computers across a network medium such as a CAT 5 cable. The network card connects to the cable using a transceiver, which is responsible for sending and receiving the electrical signals on
It provides the capability to save more information on a diskette than normal.
It provides the capability to communicate across a phone line to another computer.
It provides faster communication between the CPU and the hard disk.
It provides the capability to communicate with other computers across a network medium.
The transceiver-type setting is required for network adapters that are capable of attaching to more than one media type. Typical cards of this nature include Ethernet cards that have both twisted-pair and coaxial connectors. This is one of the more common

When troubleshooting any kind of problem, you want to check the easy stuff first. When it comes to network cards, the first thing you want to check is the link light on the back of the computer to verify that there is an actual connection to the network
A layer-2 address is a MAC address and looks like 00-0D-60-48-53-9E.
An AUI connector is a 15-pin D female connector that looks very much like a joystick port. With an external transceiver, the actual media connection is made external to the NIC using a small device that attaches via an extension cable. These types of conn

The function of a passive hub is simply to receive data from one port of the hub and send it out to the other ports. For example, an eight-port hub receives data from port 3 and then resends that data to ports 1, 2, 4, 5, 6, 7, and 8. It is as simple as t

Repeaters can be used to extend the length of the maximum distance of the different types of cables because when a signal reaches a repeater, the repeater regenerates the signal.
A hybrid hub is one that can use many types of cables. A popular example of a hybrid hub is a hub that has connectors for thinnet and twisted-pair cabling.
Mutlistation access unit
A multistation access unit (MAU) is a hub-type device in Token Ring environments. Remember that the MAUs are connected together by a ring-in/ring-out feature.

Remember that with hubs, when a data signal reaches the hub, the hub sends the signal throughout the entire network bus, which includes ports on that hub and any linked hubs. Hubs perform no filtering of traffic, which is what a switch offers!
All ports on only the linked hub
All ports on the immediate hub and any linked hubs
The port of the destination system
All ports on the immediate hub, but not any linked hubs
Switching is a fairly involved process that allows the device to have the full bandwidth when transmitting.
A switch is different from a hub in the sense that with a switch, the data is sent only to the port that hosts the destination system. This minimizes network traffic and increases throughput on the network.
All ports on the uplinked switch
All ports on the immediate switch and any uplinked switches
All ports on the immediate switch, but not any uplinked switches
Because a bridge works with MAC addresses, it is considered a layer-2 device.
A VLAN is a way to group ports on a switch so that each grouping is its own virtual network. Systems can communicate only with other systems on their own VLAN, which includes broadcast traffic. If a system sends broadcast traffic on the wire, it will be s
A router runs at layer 3 of the OSI model.
