Connecting to the Internet with Phone Lines and Modems
How to connect to the Internet using a phone line and a modem and how does it work?
One connects to the Internet via a modem or through a network of local area connection. The basic requirements for connecting to the Internet through a phone line and a modem are a computer, a modem, a phone line, and a contract with an Internet Service Provider (ISP). Nevertheless, in this section, the connecting to the Internet through a basic phone line, computer, and modem while availing of the alternatives offered by the ISP is described. Furthermore, the associated benefits are also explored. They are:
- How a phone line works with a modem
- How a modem connects a computer to a phone line
- Internet Service Providers (ISPs)
How a phone line works with a modem
A standard telephone installation comprises of a pair of copper wires that the phone company specifically installs in the user’s home or office. The copper wires have essentially more efficient in carrying more than the user’s telephonic conversations. These copper wires are capable of managing much greater bandwidth or frequency range that is required for voice calls. DSL exploits this opportunity because of its true integration and high capacity to carry out information on wires without any disturbances, specifically when a conversation is carried out on the line by the user. The plan is based on matching particular frequencies that are related to certain special tasks being carried out effectively by the user.
How a modem connects a computer to a phone line
To establish an Internet connection, a modem effectively connects a computer to the phone line. Normally, a computer with Intel® Pentium® processor essentially supports all the software that the user installs on it. Undoubtedly, an increased RAM and hard disk capacity are more important than a high processor speed. Modem is, however, a device that converts digital information to analog signals of telephone. The best option for the user is the fastest modem. The faster data transfer rate effectively leads to less utilization of the phone line. The 56 kbps modem standards are the fastest. There are 33 kbps and 28 kbps modems that are cheaper but slower. Moreover, external and internal modems both can be used effectively. While external modems can blink and display data from being either sent or obtained from the Internet, the in-built modems are quite compatible with the system.
The basic requirements for Internet connection – in addition to a computer, a modem, and a phone line – is a contract with an ISP. The ISP has a permanent connection to Internet. Usually, users can buy a few hours of Internet connection per month, for surfing and using e-mail. For the freedom of roaming, ISPs offer unlimited access to the Internet and even disk space for the user’s website. ISPs have a dial-in number for local area phones, and if a user wants to travel around with a laptop, then he or she has to choose an ISP that provides a special phone which allows the user to access the Internet at local call rates. Some ISPs can even offer services that deliver local call rates all over the world.
