DSL vs CABLE
DSL (Digital Subscriber Line) vs. Cable modemThe new competition for Internet Service Provider (ISP) is the new high-speed digital technology, which refers to as Broadband. This high-speed digital technology comes in two different forms: Cable modem or DSL (Digital Subscriber line). Cable modems use your local cable TV lines and DSL use the already existing phone lines. These two services are competing on availability, security, speed, reliability and finally price. Therefore, let's compare the two. The first component is availability. One of the main disadvantages of the DSL service is that only systems within 3 to 4 miles of telephone switching office can use DSL. Since cable doesn't have the distance limitations as DSL, cable Internet is generally for homes that are already wired for cable TV. However, many businesses aren't wired for cable. This gives DLS the advantage in the commercial area. The next competing component is security. Security is always a main concern when dealing with the Internet. Since cable modems are operated on a shared system, this have many people concern about security. Cable Internet shares its bandwidth with 100 or so TV channels. Cable is a broadcast service, so the same signa
However, the speed of DSL often depends on how close the home or business is located to a telephone company. Yet, when we look in term of amount of time a service has been available, DSL technologies are only about a year old and Cable modem technologies, on the other hand, are at least 6 to 7 years old. Cable Internet is reasonably priced. A coaxial cable traveling in a neighborhood from house to house can provide high-speed Internet to thousand of customers. The bottom line here is that neither telephone companies nor cable companies are doing everything that they can to roll out their technology very quickly. It is then limited to a maximum speed of 2Mbps. You can get a cable connection for $30 to 40 and the cost of cable TV service per month. Both cable modem and DSL provide download transfer at much faster rates than ordinary 56Kbps modem. However, this speed tends to be slower when data is being sent upstream, from your PC to the Internet. The reasons that cable service cost less than DSL is because it's on a share system. Cable modems are capable of receiving data at 3Mbps to 10Mbps. When it come to reliability, local cable company has a long history of not offering high-quality television server, so it seems even more doubtful that they will provide high-quality Internet service. The telephone company must install a special DSL modem for every DSL user at its central office. The receiving cable modem recognizes the parts of the signal that are meant for the particular customer. Therefore, cable modems, which deliver Internet access over a cable television connection, are far better established.
