Chapter 11—Networking
Selecting a Network Data-Link
Protocol (Specification)
Regardless of the type of network (client/server or peer-to-peer) you
select, you can choose from a wide variety of network data-link
protocols, also known as specifications. The most common ones in
use for PCs are listed here. Use Table 11.7 to understand the
requirements, limitations, and performance characteristics of the
major types of network data-link protocols.
Table 11.7 Network Data-Link Protocols Summary
Max Number
Network Type Speed of Stations Cable Types Notes
ARCnet 2.5Mbps 255 stations RG-62 coax Obsolete for new
UTP1/Type installations; was
1 STP2 used to replace
IBM 3270 terminals
(which used
the same coax
cable).
Home PNA 1.0 1Mbps N/A RJ-11 phone Easy home-based
cable networking via
parallel-port connections
or internal
ISA, PCI, or
PC Card NICs or
USB port;
replaced by
Home PNA 2.0.
Home PNA 2.0 10Mbps N/A RJ-11 phone Easy, faster homecable
based networking
via PCI or PC
Card NICs or USB
port.
Ethernet 10Mbps Per segment: UTP1 Cat 3 Being replaced by
10BASE-T-2 (10BASE-T), Fast Ethernet; can
10BASE-2-30 Thicknet be interconnected
10BASE-5-100 (coax; with Fast Ethernet
10BASE-FL-2 10BASE-5), by use of dual-
Thinnet speed hubs and
(RG-58 coax; switches; use
10BASE-2), switches and
Fiber optic routers to over-
(10BASE-F) come “5-4-3” rule
in building very
large networks.
Fast Ethernet 100Mbps Per segment: 2 Cat 5 UTP1 Fast Ethernet can
be interconnected
with standard
Ethernet through
use of dual-speed
hubs, switches,
and routers.
