A Team in Rocket.Chat is essentially a collection of channels, each serving a specific purpose or project. For instance, consider a scenario where your workspace includes a team designated for your organization's core members. This team encompasses a variety of channels tailored to their needs and roles.
The primary advantage here is the automation of access privileges: when a new core member joins the team, they are instantly granted access to all associated channels. This eliminates the need for manually adding them to each channel, thereby enhancing efficiency and reducing administrative overhead.
Teams are identified by: 
Like channels, Teams can also be made private so that only invited members can join or public so that all Rocket.Chat users can see them. Each team may consist of channels, which may also be either public or private.
Team security and permissions
The following options help you fine-tune the security of certain organization-wide teams. This ensures that only members with permission can send messages to the teams.
Read-only teams
Only users with the Post ReadOnly permission can send messages in Read-only teams. To allow other users to react to messages in this team, navigate to Team info > Edit > Advanced settings and enable the Allow reacting option.
Broadcast teams
Like read-only teams, broadcast teams allow only authorized users with the Post ReadOnly permission to write new messages, while other users can reply to existing messages.
However, it differs from read-only teams in the following ways:
All messages have a reply button that redirects you to the sender's direct message (DM), replying to the message as a quote.
Users can’t react to messages.
The team cannot be converted to a read-only again.
Encrypted teams
Encrypted teams have end-to-end encryption enabled across all messages exchanged by the Team members.
Team information
The team information screen gives detailed information about the selected team. These details include:
Name: The team's name, how users see the title and find the team via search.
Topic: The topic is next to the team header's title. It is a great way to provide more information about the team.
Announcement: Announcements are highlighted in a bar under the team header.
Description: The description of the team.
Private: Select if the team is private or public.
Read Only: Tells whether a team is read-only.
Archived: This tells if a team is archived. Nobody can post messages on an archived team, and a directory search will not find that team. Admins can find archived rooms using the Directory.
Password to access: Protect the team with a password and allow you to set it. If a team is password-protected, users are required to enter the password to become team members.
Mention teams
With teams, you don’t need to remember everyone’s name to communicate with a team quickly. Just mention a team — @engineersFor instance, all members will get notified instantly.
