All About Vintage Modems and Computer Networks
A computer network consists of two or more computing devices that communicate with each other through a connection. The Internet is the largest computer network. It is a global network of computers that communicate with each other using a telephone, satellite, or cable connection.
What is a modem?
The modem gets its name from a blend of two words, modulator, and demodulator. It is a device that allows your computer to communicate with other computers using a telephone connection.
How does a modem work?
Telephone technology depends on analog signals to send soundwaves over the network. Computers communicate using digital signals. For them to use the telephone application, they will need a device that can translate the signals into the correct version. Modulation is how the modem converts the digital signal into the analog version for transmission over the telephone network. Demodulation happens when the modem receives the telephone signal and converts it into digital signals for the computer.
What are the advantages of a modem?
- Low-cost Internet connectivity - Commodore devices like the Commodore 1600 have relatively low costs. They are also easy to install.
- Remote connection - It is expensive to set up a cable network. Most cable service provers overlook rural areas in favor of urban regions. But even if you live in a remote rural area, you can connect to the Internet as long as you have a telephone line.
Types of modems
- Built-in modems - Some computers have built-in cards that allow for Internet connections. The telephone line connects to the modem using an ethernet port.
- Telnet modems - Telnet modems use a text-based communication model to connect two remote computers. The computers must have a terminal program software so that they can run commands on the bulletin board service (BBS).
- Dial-up modems - A dial-up connection works by dialing a telephone number through the telephone company. You cannot make calls or receive them while the modem is dialing the network.
- Digital subscriber line (DSL) modems - They use dedicated telephone networks to send signals over the Internet. The telephone network has two lines, which allows the modem to remain connected at all times.
- Cable modems - Coaxial cables offer greater bandwidth and higher transmission speeds. The cable companies offer TV, Internet, and telephone connectivity to users. A cable modem picks up computing data from the network.
