After the release of Discord more than 5 years ago, the online communication has taken a drastic turn as it has solved various design issues that most VOIP softwares share. When compared to TeamSpeak, Skype, Mumble, and Vent, Discord has a simplified user interface.
Before Discord, users had to separately share their server address, the servers port number, and password to connect with others. But now, Discord has totally made the whole process of joining a new server pretty easy. All users have to do is share the URL that can either be used one time or set to be permanent.
