We have to connect a moniter to view raspbian on raspberry pi.But it cause some difficulties whe we using.
  What ,if we can acces raspbiam on a raspberry pi without a moniter?

Simply we can use Remote desktop softwares like Anydesk.

And we can use Putty to access raspberry pi console remotly.But we must have to be in same network for this.

The other option is to work with VNC. With the new VNC software wecan acces any devices log into same account in anywhere.
