The full form of DSL in Computer is Digital Subscriber Line. It is a cluster of technology that transmits high speed digital data over telephone lines.
How does DSL work?
DSL uses the same wires a telephone line uses and it allows the users to make phone calls and use the internet at the same time. DSL system does so by separating telephone signals into three frequencies.
The lowest band manages the telephone calls while the other two governs uploading and downloading and other internet activity. It’s possible via the DSL transceiver or modem.
The customer’s modem sends data over the telephone line to the service provider and a DSL Access Multiplexer terminates ADSL lines. It deviate voice traffic to public switched telephone network and bend data to a high speed digital line connecting to the internet. xDSL is an umbrella term for its technologies.
What are the different types of DSL in Computer?
- ADSL – Asymmetric DSL is faster and provides a larger network bandwidth for downloading in the customer’s computer rather than uploading.
- SDSL – Symmetric DSL provides an equal amount of bandwidth for both uploading and downloading, mostly used in business and corporate services.
- HDSL – High-bit-rate DSL provides symmetrical high-speed data.
- VDSL – Very high-bit-rate DSL is the fastest among all the xDSLs.
What is the difference between DSL and Broadband?
- DSL is a bit slower than the Broadband services and an older concept.
- The connection medium of DSL is standard copper telephone lines whereas Broadband uses optical fiber, coaxial cables, radio or twisted pair.
- DSL uses existing telephone lines to transport high bandwidth data but Broadband uses traditional telephone line or a dedicated cable.
