Inputstream available method | Thales IoT Developer Community

I'm using InputStream read() method to read comm connection data.
Since read() method blocks until a data received, it is not efficient way of reading.
I tried available method to prevent code blocking. It works fine as fas I see.
I wonder, how an InputStream knows amount of data ready to read. It is not written anywhere that InputStream has a buffer. Has it?
If there isn't a buffer in it, how it knows amount of coming data?
Thanks in advance.
