What is internet?

The Internet is a network of networks that allows interconnection between various computers in a decentralized manner. It does this by means of the protocol known under the name TCP / IP. The Internet is considered one of the most important inventions and was created in 1969 in the United States.

Types of Internet Connections

  • Dial-Up
  • DSL
  • Cable
  • Wireless
  • Satellite
  • Cellular

According to the technology used, there are different types of Internet access:

Analog: this technology, also known under the name Dial Up, is characterized by being slow but inexpensive. To use this, a modem is required that connects to a telephone line. From the telephone number, the PC receives the IPS through which it connects to the Internet. To send data, what the Modem does is convert the digital signal into analog and to receive it it works the other way around: it converts the analog signal into digital. The disadvantage of connecting to a phone line is that the connection is subject to limitations and data loss and, in addition, it is not of very good quality. The analog connection speed does not exceed 56 k.

IDSN: For the acronym in English of Integrated Services Digital Network, this type of internet connection is a standard for international communication that allows the sending of data, voice and videos, through a digital telephone line. The speed of this connection is between 64 and 128 kbps.

B-IDSN: It has the same functions as the previous one, but instead of using the normal telephone wiring to transmit data, it does so using fiber optics.

DSL: this connection, although it uses the telephone line, allows the telephone to be used at the same time. In addition, it is faster than the previous ones and does not require an IPS connection or waiting for the phone to be dialed. Within this connection there are two classes: ADSL and SDSL .

Cable: to connect to the Internet, this technology requires a cable modem that allows access to the broadband offered by cable television services. This technology makes use of a television channel that offers greater bandwidth than telephone lines. The speed of the wired connection offers a speed between 512 kbps to 20 mbps.

Wireless Connection: this does not use the cable network or the telephone line, instead it uses radio frequency bands. This technology offers a connection within the coverage area permanently.

T1 lines: This telephone line supports transfers of up to 1,544 mbps and consists of 24 channels that support 64 kbits per second each. This technology allows configuring each of the channels to transmit voice and data.

Satellite: through this technology the Internet is accessed through a satellite. Since the signal must travel from Earth to the satellite and back, it is a slower connection, its speed goes from 492 to 512 kbps.
