Slack is the most commonly used collaborative software in the world through which different team members or individuals can communicate with each other in a company. 

In Slack, there are different workspaces in which the owner can connect all teammates at a common platform and can take decisions in a shared workspace. 

All the conversations are organized in the form of channels. In a channel, users can do group discussions, and individual or team members can share images, files, and videos with others. 

Slack also offers video and audio call features through which members can communicate with all teams. 

Every user can join its favorite community by requesting to join the team workspace. Installation of slack can be done on almost all kinds of operating distributions such as macOS, Microsoft Windows, and Linux systems.
