Those Techie Terms
I took up Computer Engineering in college, so we had a few electronics and communication courses. Trying to make those circuits work was really fun but I hated calculating frequencies, resistances, capacities, etc. Why am I talking about this now? My cousin happened to ask me about Cat5e Keystone jack and I was clueless. Forgetting it because it had been years since my electronics courses is a lame excuse.
Cat 5 or “Cable and Telephone” is a type of cable often used for computer networks. Cat 5e is just an enhanced version of Cat 5. Keystone jack, on the other hand, is the female connector, and the matching male is referred to as the keystone plug. Still a bit confused? The photo on the right side shows a Cat 5e keystone jack. From there, I’m sure you can already figure out how does a keystone plug look like. ![]()
