Understanding ADSL

ADSL is a technology that has become very popular these days. It is a kind of internet connection that is known as home or business connection. It allows users to access internet through their existing landline connection. Before getting into details of what is ADSL, it is important to know what DSL is. DSL stands for Digital Subscriber Line and it allows you to access all websites on World Wide Web. There are many technologies that can be used to get this access. These are cabled, wireless, broadband, ADSL, 3G, 4G, and many more.

 

ADSL is one of the many ways in which Broadband is provided

Broadband is the umbrella term that is used to refer to internet connection.  ADSL is just one of them. It is different from DSL in the fact that it has an A in front of DSL. This A refers to Asynchronous which means that it is not going at the same rate. There is an up as well as down part of the line. Downloading something from internet and receiving a mail from a friend constitute the down part where as uploading something on a social media site or sending an email to a friend constitute the up part of the line. You are using the up part also when you are filling up a form on a website while it is mostly the down part when you are viewing images, text, or videos on various websites.

 

This means in ADSL, it is mostly the down pipe that is larger than the up pipe. Even in the case of developers and designers who upload lots of content over web, it is the down line that is used more if one takes into account their browsing and downloading.

 

Thus ADSL is asynchronous or asymmetric digital subscriber line and it is a type of DSL.
