What Does DSL Mean? DSL is short for “digital subscriber line.” This type of data connection uses phone lines to send and receive information. You’ll usually buy the service from a phone company specializing in non-cellular options (i.e., landlines).

There are several advantages to this approach, particularly the ability for each and every pixel to make light on their own, producing an infinitely high contrast ratio, meaning blacks can be completely black and whites extremely bright. This is the main reason more and more devices use OLED screens, including smartphones, wearable devices like smartwatches, TVs, tablets, desktop and laptop monitors, and digital cameras. Among those devices and others are two kinds of OLED displays that are controlled in different ways, called active-matrix (AMOLED) and passive-matrix (PMOLED)....

Shovelware programs might be demos, ad-filled programs, or actual usable software, but in general they’re assumed to be of little real worth....
