Understanding Connection Types
Transferring Existing Files and Settings" in the appendix.Your PC is on a local area network (LAN) at work or school. You have internet access through the network. Ask your network administrator about connection details.You want to share an internet connection provided by another computer. Use Internet Connection Sharing (or a router); see "Sharing an Internet Connection" in Chapter 17.
Picking a Connection Type
If you want to get online but don't know the best way to do it, here's some help.Dial-up connections are the most popular type. Each time you connect to the internet, your analog modem dials your ISP over a standard phone line. (If you have only one line, callers can't reach you while you're online.) Dial-up connections are slow compared with broadband, but they're a good choice for frequent travelers, because big ISPs provide local access numbers over large geographic areas. In some areas, dial-up is your only choice. Dial-up service costs about $20 (U.S.) a month for unlimited access (plus your cost for the calls).DSL and cable (broadband) connections are growing in popularity because they're:Fast. Broadband modems are 10 to 50 times faster than dial-up modems.Persistent. Broadband connections are always on. No dialing is involved.Easy to set up. In many cases, a technician comes to your home to install and configure everything. Otherwise, the ISP will mail you a kit with equipment and setup instructions.Cheaper (maybe). Broadband service costs about $25 to $50 a month for unlimited access (plus one-time setup and equipment costs, ranging from zero to a few hundred dollars). Dial-up's $20 monthly fee is cheaper, but with broadband, you don't need to pay for a second phone line for internet access or for the extra connect time needed for big downloads.
DSL (Digital Subscriber Line) uses a DSL modem to operate over a standard phone line without interfering with normal voice calls. DSL is available if you're no more than 3 miles from a phone-company central office. (The closer you are, the faster the connection speed.)Cable uses a cable modem to operate over a cable TV line (coaxial cable). If you're wired for cable TV, you can get a connection through your cable company. Cable speed can drop precipitously when too many people in your area use the system.Other connection types include satellite or ISDN (an older, slower sort-of-DSL). If your connection doesn't fit neatly into a particular category, your setup still may be similar to those described in the following sections. In any case, your ISP will provide equipment, instructions, and possibly an on-site technician.If you're not in any of these situations, you can set up your own internet connection by using:A dial-up connection through an analog modem over ordinary phone lines, orA high-speed broadband connection such as DSL or cable
