Now that you have a basic understanding of networking, let s take a look at how you connect your computer to the Internet. The most common way to connect to the Internet is with a modem and an Internet service provider (ISP) account. A modem is a hardware device that allows computers to communicate with each other by transmitting signals over telephone lines, enabling

what is called dial-up access. Modems come in different speeds the higher the speed, the faster the data are transmitted. For an overview of the different types of available modems, take a look at the following table.

Modem Type Analogs Description A type of modem that connects a computer to the Internet through a phone line. Internal modems plug into a PCI port inside a computer. External modems plug into a serial port, parallel port, or USB port on a computer. A 56 kilobits per second (Kbps) modem can receive data at about 53 Kbps. A type of modem that connects a computer to the Internet through a high-speed digital line installed by a telephone company or telecommunications provider. A digital device that connects a computer or network to a larger network through telephone wiring using DSL techniques. Modem is actually a misnomer for this type of connection because there is no conversion from digital to analog. A type of modem that connects to a local cable TV line to provide a continuous connection to the Internet. It can achieve transfer rates of about 1.5 megabits per second (Mbps). Cable modems attach to a 10Base-T Ethernet card port on your computer.

Integrated Services Digital Network (ISDN) Digital Subscriber Line (DSL)

To connect your computer to the Internet, you must go through a service provider. You can connect to the service provider through: A local area network (LAN). A LAN is a computer network that spans only a small area. LANs are confined to a single building, groups of buildings, or range of a few miles. A high speed broadband connection such as cable, ISDN or DSL. Broadband Internet connections enable high-speed data transmission through a single cable. The most common types of broadband connections are cable modems and DSL modems. Because of its multiple-channel capacity, broadband has started to replace baseband, the single-channel technology originally used in most computer networks. A dial-up connection. A connection established between computers over a standard telephone line.

With the exception of cable or DSL connections, which typically do not require a user name and password, you need to use the New Connection Wizard to set up your connection. Before going through the wizard, make sure that you have the following information available from your service provider: Specific IP address or the address of the DHCP server DNS address and domain name

Important To share your Internet connection with other computers on your network, consider using a high-speed modem such as DSL or cable. Ask your local telephone company or cable television provider whether these services are available in your area.

Because the Internet has become an integral part of people s lives and ongoing access to it is seen as a necessity, most people are willing to pay their phone or cable company a monthly fee to get the fastest access possible. Broadband is the term frequently used to describe faster Internet capability when compared with traditional modem dial-up Internet access. Broadband can be delivered through a range of technologies. These include: DSL Cable Radio/Microwave Satellite Wireless

Broadband tends to be more expensive than dial-up access or narrowband. Also, note that broadband access is not usually metered. This means you pay a monthly flat rate to access the Internet at any time without any call charges. With no per-call fees to pay, you know what your monthly bill is going to be. However, there may be installation costs that you would want to know about before signing up. There are many advantages of high-speed Internet access, such as: The connection is always on, which means you can access the Internet without the need to dial your Internet service provider over a telephone line. Information can be downloaded into your computer at significantly higher speeds than traditional modems. You can go online without making your telephone line unavailable.
