Sql Express instance is not in the list of network servers

Today, I have a requirement to work with SQL Server express. So, I setup a server with Sql server express installed and configured everything we needed. My team has 4 developers and everyone should access the sql server express to run the project. But, when they try to access the sql server express instance the server is not responding and always it results an error. When I open network servers, I found only the instances of my sql sever and in that list I didn't find the new sql server express I have setup on the server nb11. See the below screen.

So, This stop us working together and started finding what's the problem. I logged into nb11 machine and checked all the services related to Sql Server and found Sql Server Browser status is stopped. Because of this, it is not able to expose to external environment or outside of the server.

So, the solution is just start running the Sql server browser. Now, go to list of server in network servers and you started seeing the nb11 express instance there.

Now, the question is what is Sql Server Browser? Simple definition is "Provides SQL Server connection information to client computers."
