Using CAT5e

Recently we upgraded our 2 computers.We want them to communicate together by gigabit ethernet networks but to function it correctly,we have to change our old CAT5 ethernet cable.Since my husband knows a lot about computers,he knows what's the best way.He upgraded it into CAT5e which is excellent to use in compliance with 1000BASE-T.Now,we're happy because the two computers comunicate faster and it's easy for us to send files to each computers.
