Cable+Modem

=Cable Modem= Author:Renee Cha Cable Modem is a type of modem(or a device) that enables you to hook up your PC to a local cable TV line and receive data at about 1.5 Mbps. It changes a digital signal to a analogue by connecting to cable network, this can help you to connect Internet with high speed. Compared to analog dial-up, cable Internet dramatically increases the bandwidth between the user's computer and the Internet.In order to prevent users with lower-cost cable access from hosting high-traffic Web servers, the upload speed is approximately five times slower than the download speed. Cable operators also routinely change IP addresses assigned to users to prevent Web hosting

A cable modem has two connections: one to the cable wall outlet and the other to a PC or to a set-top box for a TV set.Although a cable modem does balance between analogue and digital signals, it is a much more complex device than a telephone modem. It can be an external device or it can be integrated within a computer or set-top box.

Cable modems connect to the computer via an Ethernet port, which is an always-on connection. Ethernet is a shared medium, and the individual user's speed will vary depending on how many customers are sending or receiving data on that cable segment at the same time. For example, when kids come home from school in the afternoon, many neighborhood users experience slower speeds.
