Cable vs. DSL: What's the Difference?
Cable internet uses coaxial cables for data transmission, while DSL uses phone lines. Cable generally offers higher speeds.
Key Differences
Cable internet provides connectivity through the same coaxial cables used by cable television, making it widely available in areas served by cable TV. DSL, or Digital Subscriber Line, uses existing telephone lines to offer internet access, which means it's accessible in most areas with phone service.
Cable internet typically offers higher bandwidth, leading to faster internet speeds compared to DSL. However, cable internet performance can decrease during peak usage times when many people in the same area are online. DSL speeds are generally more consistent, but are often slower than cable.
DSL internet connections are dedicated to a single subscriber, leading to potentially more consistent speeds regardless of local demand. Cable internet, however, shares bandwidth among multiple subscribers in the same local area, which can lead to congestion and slower speeds during peak times.
The installation process for DSL internet usually involves activating a line and setting up a modem, which can often be done by the user. Cable internet might require a professional installation, especially if the residence isn't already wired for cable service.
Cable internet often has higher starting costs and monthly fees due to its faster speeds, while DSL can be a more budget-friendly option for users with moderate internet needs. Both types of connections have various plans and packages to cater to different usage requirements.
