NETWORKS DETAIL Computer connections For twisted-pair LANs: A desktop computer connects to a twisted-pair LAN through a network interface card (NIC) that resides in a slot in the computer, or through a similar interface built in to the computer itself. The RJ-45 plug of the network cable plugs into an RJ-45 jack on the card or in the computer. A portable computer may have a built-in connection using an RJ45 jack, or it may use a PC card that inserts into a PC card slot in the computer. (Some PC cards take up two slots and have room for an RJ-45 jack that is integral with the card; others take up only a single slot but require a short cable that provides the RJ-45 jack.) For thin coaxial LANs: A desktop computer typically connects to a thin coaxial LAN through a network interface card (NIC) ; built-in BNC connections are uncommon. Portable computers connecting to thin coaxial LANs use a PC card with a short cable that provides a BNC connection. In all cases, the LAN cable connects to the computer through a BNC "T" connector. Hidden network cables and equipment: In many network installations, the hubs are kept in equipment closets and the cables are hidden in the walls. In these installations, wall outlets with RJ45 jacks are the only visible components of the network wiring. For such a network, you use a short length of network cable to connect from the computer to the wall jack.

Computer
connections
For twisted-pair LANs:
A
desktop computer connects to a
twisted-pair LAN through a
network interface card (NIC) that
resides in a slot in the computer,
or through a similar interface
built in to the computer itself.
The RJ-45 plug of the network
cable plugs into an RJ-45 jack on
the card or in the computer. A
portable computer may have a
built-in connection using an RJ-
45 jack, or it may use a PC card
that inserts into a PC card slot in
the computer. (Some PC cards
take up two slots and have room
for an RJ-45 jack that is integral
with the card; others take up only
a single slot but require a short
cable that provides the RJ-45
jack.)
For thin coaxial LANs:
A
desktop computer typically
connects to a thin coaxial LAN
through a network interface card
(NIC) ; built-in BNC connections
are uncommon. Portable
computers connecting to thin
coaxial LANs use a PC card with a
short cable that provides a BNC
connection. In all cases, the LAN
cable connects to the computer
through a BNC "T" connector.
Hidden network cables and
equipment:
In many network
installations, the hubs are kept in
equipment closets and the cables
are hidden in the walls. In these
installations, wall outlets with RJ-
45 jacks are the only visible
components of the network
wiring. For such a network, you
use a short length of network
cable to connect from the
computer to the wall jack.
