The Internet has an unending ocean of information and has gained a lot of popularity over the years. Using it is not so difficult. Let us see how it works.

The Working of the Internet

Each computer that can use the Internet has a unique IP address. No two computers share the same IP address. The IP address comprises four numerals that are separated by full stops.

Human users have also been facilitated by the introduction of domain names. Domain names are the alphabetical manifestation of the numerical IP address by a DNS (Domain Name Server).

Transfer of Information

The information is transformed into minute packets and is transmitted from one computer to another. This function is performed by a machine called stack.

The Internet also offers facilities such as e-mail, web browsers, news readers, and chat facilities.

There is no other feeling that gives immense satisfaction than a prolonged and lively chat with a close friend or a beloved. For the fulfillment of this requirement, the Internet also offers amenities such as IRC programs.

All these software use numerous methods to encode and decipher the information passed between computers.

Servers

Servers are machines that perform a specified role on the Internet and their presence is very essential for its successful operation. They provide access to the infinite files called websites available in the Internet. The servers send requests to the various webpages that make up a website.

The website to which the request is sent sends the concerned webpage from its numerous webpages. Mail servers are servers designed to decipher and modulate the packages utilized by the e-mail. It is the source from where a person's mail can be downloaded.

Features

The Internet offers a wide range of services such as downloading and uploading. One of the most popular features is downloading.

Downloading is the process by which information such as songs, games, wallpapers, screensavers, and different files are saved in a person's computer from a website. Uploading is just the opposite of downloading as the name suggests. It is the process of sending information from a distant computer to any website.

Modem

Modem is simply the acronym for modulator-demodulator . It is one of the most important components required by a person to access the Internet. It is a simple device that is connected to a telephone for its functioning. The modem converts the electrical signals to analog signals (modulation) and vice-versa (demodulation).

This conversion is essential as telephones cannot understand electrical signals and computers cannot decipher analog signals.

The Internet is one of the numerous inventions of mankind which has gained importance due to the host of benefits it offers.

It is a wide network of computers which offers information from remote computers and also helps us to connect with people all over the world. Recently, websites even for matrimonial purposes have been launched.
