A reader asks:
"54g 802.11b/g WLAN with 125HSM, speed booster support 10/100RJ- 45 Ethernet LAN. Is this equal to a network card with integrated 10/100 Base- T Ethernet Lan and 802.11b/g WLAN wireless?"
In general, yes. Let's split apart the specs:
54g 802.11b/b WLAN with 125HSM speed booster support
vs
802.11b/g WLAN wireless
Most of the spec is the same for the two systems, which refers to wireless networking:
- "54" refers to the network transmission speed (54mbps).
- "801.11b/g" refers to the networking standard.
- "WLAN" is short for wireless local area networking, aka WiFi and Wireless networking.
The only part that is different is:
- "124HSM speed booster support" is a proprietary method the manufacturer created to speed up wireless transmissions. In general, you cannot use the proprietary methods, unless you use the same WLAN equipment everywhere. In practice, that does not happen, so the speed boost is useless. In fact, it is unnecessary, because 54mbps is probably already faster than your Internet connection.
10/100RJ- 45 Ethernet LAN
vs
10/100 Base- T Ethernet Lan
Both of these are also the same, and refer to wired network specs:
- "10/100" means that the system supports the older, slower 10mbps spec and the newer 100mbps spec.
- RJ-45 is the technical name for the connector used by network cables. All wired networks use the same connector.
- "Base-T" is the technical name for the networking standard now used by nearly all systems; part of the spec is the RJ-45 connector.
- "Ethernet" is the name of the standard in which computers communicate with each other through wired connections.
- "LAN" is short for local area network, which refers to networks that are suitable for use within offices and homes -- and not across the country.
