NIC The must match the Address/Data Bus of the computer.
ISA
PCI
55
Installing the NIC in the computer.
NIC installed inside the computer. Normally plugs into a bus slot. Some are built right into the motherboard. Plug-in boards must be configured correctly.
56
NIC Configuration Methods
Plug-and-Play
EEPROM Jumper pins
57
Preparing to Install the NIC
Ensure there is an open bus slot.
Ensure the adapter is compatible.
Ensure there are system resources available. Ensure all installation items are available.
Ensure all software is available.
58
Installing the NIC Hardware
Configure the NIC to available resources.
Use a ground strap.
Remove cover from the computer.
Remove rear panel slot cover plate.
Remove card from its antistatic bag and immediately plug it into motherboard. Secure card slot cover plate to computer.
59
Installing the NIC Software
Loading the device driver used by the NIC. Loading any utilities supplied with the NIC.
60
NIC Device Driver
Supports communication between the NIC and OS.
Automatically installed and configured if both NIC and OS support PnP. In other cases, driver loaded from floppy or CD supplied with NIC.
61
A more recent device driver may be available at the website of the NIC manufacturer.
62
Troubleshooting the NIC
Is NIC talking to the motherboard? Is the NIC working internally?
Is the NIC communicating with the external network?

Twisted-Pair Advantages
UTP is inexpensive.
Workstations isolated from each other by central hub. Easy to add workstations to segment.
Easier to route than coaxial cable.
Easier to troubleshoot than coaxial cable network.
69
Twisted-Pair Disadvantages
UTP cable is susceptible to RFI/EMI.
Suffers crosstalk between wire pairs.
Poor conductor; attenuates signal more quickly than coax. Maximum segment length half of coax.
STP cable more expensive than UTP cable or coax. Difficult to work with shielding.

Coax Advantages
Resistant to RFI.
Good conductor.
Longer network segments. Thinnet: easy/inexpensive workstation interconnection. Thicknet: stronger, more durable than any other network cable.
76
Coax Disadvantages
Each segment must be terminated.
Break cable in disables entire segment. Difficult to add workstations to a thinnet segment. Thicknet: difficult to use, heavy shield braid and foil. Thicknet: requires special piercing tap and transceiver.

Ethernet
Developed by Xerox in early 70s.
Has become most popular networking technology in use today. A variety of speeds and cabling options have evolved.
It is fast, inexpensive, and flexible. It continues to evolve. Majority of new networks use Ethernet.
93
Networking is all about sending data from one location to another.
