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.
ADSL & Cable is the fastest growing way to connect to the Internet. ADSL uses standard analogue lines with advanced circuit boards to allow high-speed connections on the Internet. In theory the ADSL can allow connection speeds of up to 9 MB a second, but no provider gives these types of speeds. The ranges typically available are from 256kb to 2mb per second. If available in your area, I would recommend using this type of connection, which is typically 10 times the speed to a standard modem connection. Cable modems are much the same, but use fibre optic cables to transmit the data, the same cables that carry your TV signals.
So the question is what do you buy? Well the good news, is that most, if not all computers are sold with modems, and almost all companies provide ISDN/cable/ADSL modems when you signup. (Check with the Companies that you have decided to go with before buying.) Remember though, if all you use the internet for is to collect and send emails, then a modem dialup on a pay as you go contract, is basically all you require.
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.
