Do I need a switch for a network of computers and printers?

Question

Computer networks

Good afternoon!

Do you need a switch if you want to combine a network in which one computer is a server so that files are quickly transferred over the network? Can this switch be connected to a router so that an Internet connection is available from devices connected to the switch? What should be the optimal bandwidth of the switch to exchange files between computers?

Answer 1

A switch is needed if there are not enough ports on the router to plug in all the devices.
Yes, you can connect it to a router.
Modern networks are usually built on gigabit. This is the port bandwidth.
