theoretical transmission speeds of 10 to 54 Mbps, which translate to actual throughputs of roughly 4 to 20

Mbps. (To learn about the differences among "a," "b," and "g" technologies, see our feature story "Unwire

Your Home," Fall 2003.)

Ethernet

The most popular LAN communication technology. Originally designed in the 1970s for coaxial cable, it is

now most frequently used with Category 5 twisted-pair cable. All nodes or networked devices take turns

sharing the technology. Because of this, various collision detection techniques are used, making the

technology efficient for small networks. There are various types of Ethernet, including 10-Mbps (traditional

Ethernet), 100-Mbps (Fast Ethernet), and 1,000-Mbps (Gigabit Ethernet).

Hosts

PCs, networkable printers, and multimedia devices, among other hardware, that can send or receive data

across a network.

IP (Internet Protocol) address

A numerical identifier for a device on a TCP/IP network. The IP address format is a string of four numbers,

each from 0 to 255, separated by periods.

MAC (media-access control) address

A preassigned 48-bit network address that is unique to a given network interface card and can be used to

identify networked devices for security purposes.

Media receiver

A device that streams audio and in some cases video signals from computers to TV sets or stereo systems

via wired or wireless Ethernet.

NAT (Network Address Translation)

A technique—generally applied by a router—that makes many different IP addresses on an internal

network appear to the Internet as a single address, concealing the specifics of the internal network.

Personal video recorder (PVR)

A device that records TV shows from broadcast, satellite, or analog or digital cable TV signals. Standalone

PVRs are available, but multimedia PCs also offer this technology, as do graphics cards that can be

installed in regular PCs.

Phone-line

A standard set up by the Home Phoneline Network Alliance (www.homepna.org

). The HPNA 2.0

specification permits 10-Mbps network connections over existing phone wiring without interfering with

normal use. An HPNA 3.0 spec calling for higher-speed networking is under consideration.

Power-line

A networking technology that uses a home's electrical wiring to carry data at a maximum throughput of 14 Mbps.

Power-line products adhere to the HomePlug 1.0 specification.

Print server

A device that enables printer sharing on a network. Some home router products offer built-in print servers,

and many standalone wired and wireless print servers are available.

Residential or home gateway

A router used in homes and offices that typically includes such features as a cable or DSL modem, a
