Windows device driver information for 56kefxspC External Speakerphone Modem

Modems are devices which facilitate conversions of analog signals into digital form that can be interpreted by computer hardware and software. It also has the capability of converting digital data into analog signal packets for it to be able to travel through analog phone lines. The first task of converting analog signals into digital form is called modulation while the next is known as demodulation, hence the word 'modem'.

The common use of this device is by connecting the personal computer or laptop to the internet. Data transferred or used is known through bits per second or bps. You see this when you have successfully connected your computer or laptop to the internet. Another way of measuring is through Baud. This counts the number of times the modem changes its signal state per second. A lot of high speed and advanced modems are being invented nowadays. These are known as cable modems, DSL and ADSL modems. In big industries (notably in telecommunications), they use wide band radio modems. This wide band modems sends repeating frames of data at very high data rates over microwave radio links. Reports also say that a number of microwave modems can only send more than a hundred million bits per second. Radio networks, on the other hand, use only narrow band radio modems. This is mostly used for low data rates of up to 19.2k. A new different type of modem, known as the optical modem sends out data over optical fibers.
