What does DSL mean in IT terms?

 

Internet usage is increasing day by day and IT experts are striving to bring latest technology to accelerate internet browsing speed. Currently, there are various Internet access technologies such as broadband, ADSL (digital subscriber line), wireless Internet and switched Internet.

DSL digital subscriber line is a group of technologies used to transfer data and information over cables in a local telephone network. In this article, we will explain the topic that DSL stands for in computer terms.

But DSL internet works faster than dial-up and cable internet and is quite famous in various countries because of its cheap fees and reliability. DSL has become popular because it is offered on the same telephone lines that consist of copper wire entering your home. So you don't need to interrupt your internet connection or phone call to use either. Switching from a dial-up Internet connection to a DSL connection is not a difficult task. You just need to call your ISP and they will get it to you within days. The ISP mainly provides a DSL modem and installation service for free and your DSL internet bills are provided with your phone bill. Several tests show that the DSL works 50 times faster than the dial-up network.

Advantages of ADSL

1. It offers you fast internet connection,
2. It requires little hardware to work as a DSL modem,
3. It costs you around $ 10 to $ 15 per month,
4. It allows you to use a phone to make and receive calls and use the internet simultaneously,
5. Your DSL allows you to be connected to the Internet 24 hours a day.
6. DSL is much better than a wired network. The performance of the wired network has deteriorated as more and more people subscribe to it, yet this is not a problem with DSL.
7. The key to high speed DSL internet is that it transmits data in digital format. Older internet connectivity solutions have lost their value as they convert between analog and digital signals.

Disadvantages of DSL

1. DSL connections work best if you live near the office of the Internet service provider. However, now these service providers have developed telephone exchanges in every city to overcome this problem,
2. It may happen that the DSL service is not accessible everywhere.
3. It offers higher speed for receiving data but low speed for sending data.

Types of digital subscriber line

The digital subscriber line is broadly divided into two categories:

Asymmetric DSL: In this type of DSL connection, you will get more bandwidth to download data compared to download bandwidth. Most of the time, home users receive this type of DSL connection which offers a download speed of 5 Mbps and a upload speed of 1 Mbps. ADSL, RADSL, and VDSL are the most common forms of asymmetric DSL.

Symmetric DSL: In this type of DSL connection, you will get equal bandwidth to download data compared to the download bandwidth. Usually the upload and download speed is offered at 1.5Mbps and is associated with business class customers. Like asymmetric DSL, symmetric DSL has common forms SDSL, HDSL, and SHDSL.
