Hello Everybody,
I am sorry for the first time to join this network forum.
Anyways, i am just a starter learning about Networking and hope that i will improve more from you.

I have some questions regarding networking.
If a company have 4 Branch offices and they want to those branch offices access Data to head office.
-What We should do first?
-How do we connect from Branch office to head office, By wire or any ways?
-How many types that we can choose to connect them to Brand office?

or anyway that you have experiences about this, please let me know.
Best regards,
