every timei set up or alter a network it saysi have LAN in fact everything points to highspeed LAN but sure enough if i look behind my comp theres a little box with the words cable modem on it. i thought they were the same but when asked my connection type once i was offered dsl/cable modem and highspeed LAN as different results.

Cable modem typically means that the modem is directly connected to your computer. Highspeed LAN usually means that the modem is connected to a router or a switch of some kind, which is usually done so that more than one system on the LAN can use the connection.

The LAN is the local area network. This contains the pcs in the network, the printers, network switches and the LAN side of a router.
LANs used to run at 10 Mbps; later on 100 Mbps became the standard and this is often called Fast Ethernet or High Speed LAN or Fast LAN. (Now there is also 1000 Mbps or 1 GB.)
A cable modem interfaces with the WAN port of a router and links the router with the Internet. Typical Internet speed is for Cable is 2 Mbps to 8 Mbps, far slower than LAN speeds.
Now if you have only 1 pc on the network you may well be plugging the pc directly into the cable modem and have no router, no switch, no other LAN hardware. It sounds like this is your case so it adds to the confusion.

I see your point. Forget everything you've been told and listen to this:
The word "modem" stands for "modulate" and demodulate," OK? So, the side of the box that's connected to the street (TV cable, phone line or whatever) is doing the modulation/demodulation things; that is, translating what comes from the outside world into signal data your computer can understand.
Now, the side of the modem box that's connected to your computer is seen by the computer as a local network device; and indeed, it is -sits there right behind the PC. And that side of the modem box and your PC communicate over a piece of network cable which makes it a "LAN," or Local Area Network.
So, from the computer's point of view, it is connected to a LAN. Depending on what the modem box communicates to the PC, and any installed drivers on the PC, you'll get more or less detail about the devices that "populate" the LAN. Thus, a printer will communicate a LOT of data about itself, so it can be controlled from the PC -as well as just print out data streaming to it. But a very basic modem box will be practically "transparent" to the PC, and just do its job. The only thing it needs is an "address," a numerical code that tells the PC what hunk of data belongs to it -and not the printer, scanner, etc.
Clear?

LAN = local area network. The parts of your LAN are your computer (network card), your cable modem, any routers set up, and any other additional computers you have connected to the routers.
Your LAN speed is the speed your computer transfers information to the router or modem. This is the speed that the cable lets information travel.
Your modem then connects you to the internet. This is at whatever speed tier you chose from your ISP when you ordered your service.

The Modem Connects to the Highspeed LAN.(LAN is not an object. It stands for Local Area Connection, basically it a network that connects you to the Internet through your modem.)

You can only use DSL cable if your connection is done via cable, like Virgin. If you have to use a normal phone line to connect you can only use ADSL. LAN is relative, it just means Local Area Network, confined to a small area or single building, that can have 2 PC's or 100 on a network. A WAN, Wide Area Network is generally what your connecting to when you go on line. Your ISP dictates the speed anyway, say 4Mbps max to your modem/router, but the ethernet from the modem can go up up to 100Mbps, but only at that speed on the LAN network, overall you still can't go faster than your ISP specs when transferring data to/from the net, WAN.

If you're referring to the LAN connection in My Network Places, that is just talking about your NIC and the local connectivity. This can be directly to the Cable-Modem's LAN port or to a router. The connection type refers to how your computer is connected to the internet. If you select DSL/cable modem it assumes your computer is directly connected to the cable modem. If you select high-speed LAN, that will enable you to communicate faster with PCs connected to you router. High-speed LAN can be anywhere form 100 megabytes up to gigabytes from PC to PC.

LAN = local area network.
In this case you are using your LAN connection in your computer to connect to a cable modem. The cable modem then connects you to the internet.

All LAN cables use copper wires. Fiber based LAN uses optical fiber. the most popular type of LAN cable is UTP (unshielded twisted pair) available in Cat-3 (10mbps), Cat-5 (100mbps) and Cat-6 (1gbps) qualities. The UTM cable has 4 pairs of wires. The pairs consist of wires which are twisted together so that they cancel out each other's electro-magnetic field. As the cat-rating increases, the data transmission speed increases, requiring even greater sheilding and separation. Cat-6 cables are shielded and separated using plastic trays while Cat-3 cables are simply bunched together. The other type of popular cable is Co-axial (like audio-video cable). HTH
