How Is Broadband Internet Service Connected to My PC?

Posted on July 25, 2011. Filed under: BROAD BAND |

Broadband Internet service delivers a consistent amount of network bandwidth at speeds significantly higher than old-style dial-up access. Broadband service is connected to a PC by an Ethernet cable or through a wireless device.

Broadband Sources
Broadband Internet services reach the consumer in several different ways. Cable modems, using a special device that reads a signal sent by a cable company, tends to be fast and consistent, but prices vary depending on the customer’s subscription package. Digital subscriber lines use a high-frequency section of a normal phone line; DSL is fast and efficient but is less available in rural areas. Wireless broadband is delivered by a device that connects to the local cellular network–pricing and availability varies by community.

Modems
Cable and DSL connections require a modem. This device connects to a coaxial cable or phone cord and actually sends and receives network traffic. Some service providers will lease or sell a modem to the consumer. Wireless broadband is typically provided through a small transceiver that plugs into an open USB port on the computer.

Routers
A modem typically uses an Ethernet cable to run from the modem to a networking port on the PC. To use several computers with one active Internet connection, add a router–these devices split a network connection several ways, and many routers have a wireless option to permit Wi-fi (short-range wireless) connections as well. The modem plugs into the router, and the PC and any additional machines plug into the router.

Cables
Except for USB transceivers, which have no wires, a home PC will be connected to a router or modem by an Ethernet cable. This cable, which looks like a phone cord with a slightly wider end, plugs into the Ethernet port on the PC, and into the “PC” port of the line-out ports on the modem or router.

Software
Some routers or modems require the user to run an installation CD or DVD to complete the set-up process. Follow the manufacturer’s instructions carefully. Some services, like DSL, require a straightforward but somewhat involved set-up process that links the DSL modem to your account with the phone company; failing to follow this process will make the connection unusable.
