Join Mike Meyers for an in-depth discussion in this video Fiber-optic and coaxial cabling, part of CompTIA A+ Exam Prep (220-901) Part 5: Networking.
- Now, if you've been following along on my videos,…up to this point you would think…that the only type of network cabling out there…is good old unshielded twisted pair.…Well, my friends, that's not true…and that's what this episode is all about.…In particular, I want to talk about…two other types of cabling technology,…fiber optic and coaxial.…While not nearly as well-used, as commonly used,…as unshielded twisted pair,…these two types of technologies…have a lot of important uses in the networking world,…and that's why the A+ wants me to cover it.…
So let's dive right in…and let's start off with fiber optics.…Fiber optic is the cable you turn to…where regular twisted pair might not be what you need.…Fiber optic uses light instead of electricity…and it has some real big benefits over twisted pairs.…For example, fiber optic cable can be very long,…depending on the standard, 40 kilometers is not uncommon.…The other nice thing about fiber optic is that…it's completely impervious to electromagnetic interference.…
So magnets and motors and things like that…
The CompTIA A+ 220-901 exam is comprised of six key parts. The fifth, networking, is covered by this course. Instructor Mike Meyers provides an introduction to networking by exploring cables, network IDs, IP addresses, and ports. He explains how to deal with a DNS, configure a router, and set up a wireless network while applying security standards. He also discusses Internet connections, including dial-up, broadband, wireless, and more.
Note: The six courses designed for the CompTIA A+ (220-901) exam preparation include core processing, core hardware, peripherals and building a PC, displays and printers, networking, and laptops and mobile devices.
