Why Test your ADSL/DSL/Cable/Modem speed? Simply to know actual download and upload speed when surfing web. It's important to choose or evaluate an ISP (Internet Service Provider). Many speed test websites calculate bandwidth via downloading and uploading a block data from their website. However, you probably need to know speed when surfing other websites; then it won't work.
Many people who have cable TV can now get a high-speed connection to the Internet from their cable provider. Cable modems compete with technologies like asymmetrical digital subscriber lines (ADSL). If you have ever wondered what the differences between DSL and cable modems are, or if you have ever wondered how a computer network can share a cable with dozens of television channels, then read on. In this article, we'll look at how a cable modem works and see how 100 cable television channels and any Web site out there can flow over a single coaxial cable into your home.
Another benefit of the cable modem for Internet access is that, unlike ADSL, its performance doesn't depend on distance from the central cable office. A digital CATV system is designed to provide digital signals at a particular quality to customer households. On the upstream side, the burst modulator in cable modems is programmed with the distance from the head-end, and provides the proper signal strength for accurate transmission.
Fast Internet, today, includes a lot of hype, and 2 major types of connections: cable modems and ADSL. In each case, we first install an Ethernet card on our system, and place some device at our house, that connects our tiny home LAN to the network of the communications provider. Lately, Bezeq has been using providing (or selling) ADSL modems that connect to the computer via USB, or even internal (PCI) ADSL modems.
