Here are some basic FAQs answered about Telegram:

How does Telegram work?

It works on all your devices at the same time; messages are synced seamlessly across any number of phones, tables or computers. Users can send messages, photos, videos, and files of any type (such as doc, zip, mp3 etc.), and create groups as large as for up to 200,000 people, or channels for broadcasting to unlimited audience. The service also supports end-to-end voice and video calls, as well as voice chats in groups for thousands of participants.

What is the difference between groups and channels?

Groups are meant for sharing information with friends, family or collaboration in small teams; these can be for as many as 200,000 members. A group can be made public; also, you can decide if a new member should have access to earlier messages. You can also pin important messages on the top of the screen so that it is visible to all the members, including the new inductees.

A channel, on the other hand, is used to broadcast message to a very large audience. A message, posted in a channel, is signed with the channel’s name and photo, and not those of the user. When the message is viewed, a ‘view counter’ of each message in a channel gets activated.
