1. Broadband : Broadband connection is simply a technology which refers to transmission of wide bandwidth data over a high speed internet connection. The connection medium can be coaxial cable, optical fiber, radio or twisted pair. It is just like a superset which refers to any high speed internet technology. In broadband internet signal to and from a device happens through a traditional telephone line or a dedicated broadband cable meant for internet connection. 

2. Digital Subscriber Line (DSL) : Digital Subscriber line which is a communication medium used to transfer digital signals over standard telephone lines. DSL is just like a subset of broadband as it is one of these technologies. In Direct Subscriber Line existing telephone lines are used to transport high-bandwidth data. So it is easy for ISP companies to provide internet connection without laying new lines. All travels in a line and just help of a splitter/filter frequencies used for voice and the frequency used for data are separated.

*Broadband includes some high-speed transmission technologies such as:

1.Digital subscriber line (DSL): The availability and speed of your DSL service may depend on the distance from your business to the closest telephone company facility.

2.Cable modem: Subscribers can access their cable modem service by simply turning on their computers ,without dialing-up an ISP.

3.Wireless:  Wireless broadcast can be mobile or fixed.   

4.Fibre: Fibre optics technology converts electrical signals carrying data to light and sends light through transparent glass fibers about the diameter of human hair.

5.Satellite: Satellite broadband is useful for serving remote or sparsely populated areas.

6.Broadband over powerline(BPL): BPL can be provided to homes using existing electrical connections and outlets.

*Types of DSL transmission technologies:

  1. Asymmetrical Digital Subscriber Line(ADSL)
  2. Symmetrical Digital Subscriber Line(SDSL)

Features of Boardband :

  • High-speed internet: Broadband provides faster internet speeds compared to dial-up connections, which means you can download and upload files quickly and stream videos without buffering.
  • Always-on connection: With broadband, your internet connection is always on, so you don’t have to dial in every time you want to use the internet.
  • Multiple users: Broadband allows multiple users to connect to the internet at the same time without slowing down the connection speed.
  • Wide availability: Broadband is widely available in most urban and suburban areas, making it easier to access the internet from almost anywhere.
  • Different types of connections: Broadband can be delivered through various technologies, such as cable, DSL, fiber optic, and satellite, each with its own advantages and disadvantages.
  • Improved multimedia experience: Broadband makes it possible to enjoy high-quality video and audio content, such as streaming movies, music, and video conferencing without the quality being compromised.
  • Cost-effective: Broadband connections offer a cost-effective option for internet access, with many providers offering affordable monthly plans.

Features of Digital Subscriber Line :

  • High-speed internet: DSL provides fast internet speeds, with download speeds ranging from 1 to 100 Mbps, depending on the type of DSL technology and the distance between the user’s location and the service provider’s equipment.
  • Always-on connection: Like other broadband technologies, DSL offers an always-on connection that eliminates the need to dial in every time you want to access the internet.
  • Different types of DSL: There are different types of DSL technologies, including Asymmetric DSL (ADSL), Symmetric DSL (SDSL), and Very High Bitrate DSL (VDSL), each with its own advantages and disadvantages.
  • Distance limitations: DSL technology has distance limitations, meaning that the further you are from the service provider’s equipment, the slower your internet speed will be.
  • Compatible with existing telephone lines: DSL uses existing copper telephone lines, so you can use your phone and internet at the same time without interfering with each other.
  • Cost-effective: DSL is a cost-effective option for internet access, with many providers offering affordable monthly plans.
  • Security: DSL provides a secure internet connection, with many providers offering advanced security features to protect users from online threats.
