DSL stands for Digital Subscriber Line, which is a connection that uses pre-existing copper phone lines to transmit internet signals to a home. This makes it the most common type of internet in the U.S. Because it’s widely available and runs on established infrastructure, DSL is usually cheaper than other connections and available to more rural communities. The most common type of residential DSL is ADSL, or asymmetrical DSL. This means your data transfer rates are faster in download speeds than upload speeds. This is great for people who like to stream videos or browse the web a lot, yet it’s not so great for users that need to send large files over the internet (i.e. remote workers).
