You have been hired to upgrade a network of 50 computers currently connected to 10 Mbps hubs. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occuring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a short memo describing the upgrade and, if possible, include a drawing of the new network.
this is a question in my networking book

it's not a question i have to answer yet but it's a question i would like answered by someone that knows about this shit for future reference since said book doesn't even touch on it
