What is the actual difference between Cat-5 and Cat-5e?

From the title, this sounds a whole lot like a repeat of this question, but it isn't, I promise. Because he wanted to know whether you could tell from looking at a cable whether it was Cat-5 or Cat-5e, based on a few pictures and some really shoddy…

Why is CAT rating not applied to switches?

I see patch panels all come rated as CAT5e, or CAT6 (and so on). I understand the difference between CAT5e and CAT6 cables, more stringent interference shielding, etc. What I don't understand is why switches aren't rated as CAT5e or CAT6? Instead,…

Physical difference between Cat 5 and Cat 5e cabling?

(This isn't really server-related, but it seems more appropriate here than SO or SU.) When we had this house built, we had network cabling run inside the house, or so I'm lead to believe. It's currently hooked up to the phone line. Unfortunately,…

Should Cat6 cables be used for servers ('important hosts') rather than Cat5-E?

Wouldn't you want your crucial hosts being served with the most signal-reliable/improved method of connectivity? Gig Switch<->Cat5E<->Server? or Gig Switch<->Cat6<->Server? My understanding about Cat6 is that it delivers improved signaling between…

Sanity Check: Is my CAT5e cable probably bad, or do I just need different connectors?

I'm working with a small company, and since I'm the only one with even a half-ounce of network infrastructure experience I've got the job of wiring up our network. So please forgive my newbie-ness. Needed to run some CAT5e cable up the outside wall…
