ADSL stands for a technology described literally in Castilian as "Asymmetric Digital Subscriber Line", its acronym comes from the English name "Asymmetric Digital Subscriber Line"; This system enables the transfer or emission of all types of digital information enjoying broadband speed through telephone lines, thus providing a multiplicity of services such as Internet service, for example, that is to say, thanks With ADSL users have the ability to access the Internet without having to intercept or interrupt incoming telephone calls to a line.
In other words, it is a high speed digital line or technology supported by a braided copper cable that guides the conventional telephone line; This is classified as a type of Internet connection that provides digitized data transfer over a telephone line.
Nowadays, the different telephone companies are installing other ADSL systems such as ADSL2 and ADSL2 +, which manage to differentiate themselves from the first due to the speed and technology used by them, since ADSL manages to reach download levels of up to 8 Mb per seconds while the other two have the capacity to reach up to 24 Mb per second, although the limit for sending them is 1 mega per second.
It is important to make clear that ADSL technology has a lower bandwidth than other technologies, which among them we can mention technologies such as cable or Metro Ethernet, in these cases the urban cabling of these is made up of fiber optic wires and not copper as is the case with ADSL, devised around the 1950s and 1960s.
