Before choosing between ADSL and optical fiber, it is advisable to know how they work, what are their main differences and understand which one should be installed. Having a good internet connection is an essential requirement for everyday life: watching a movie on some platform on-demand, using a voice assistant, remotely managing home-related applications, but also working in smart working or taking lessons remotely, these are all operations that require an ADSL or fiber optic line. In short, technology nowadays can no longer stay out the door, and it is important to be able to access the web quickly.
