Join Mike Meyers for an in-depth discussion in this video ATX and ITX, part of CompTIA A+ Exam Prep (220-901) Part 2: Core Hardware.
- The ATX form factor has been the predominant form factor…in the computing world for getting close to 20 years.…So, if it's been around so long,…well, what gives it such legs?…Well, first of all, it was free.…Intel pushed the standard,…and as a result of that, everybody got into it,…and the Taiwanese manufacturers and everybody…started to back it.…And once you get a standard that everybody likes…in the computing world, it's hard to break away from.…And we shouldn't; ATX works absolutely great.…So in order to appreciate ATX,…what I did is I've got a number of ATX systems…in front of me, but here is a motherboard…from the 1990s, and here is a brand new motherboard.…
So, even though they're many, many years apart,…they're both ATX.…So let's start with this oldie goldie right here.…This is a full-size ATX motherboard.…It's 12 by 9.6 inches.…And one of the things that ATX did…that fixed a big problem with AT…is that the AT form factor could only have little holes…for individual items, and that didn't really work too well.…
The CompTIA A+ 220-901 exam is comprised of six key parts. The second, core hardware, is covered by this course. Instructor Mike Meyers explains the essential components and functions of motherboards, power supplies, and hard drives. He also shows you how to work with chipsets, troubleshoot electrical issues, implement RAID, and how to determine which hard drive technology to use depending on the circumstance.
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.
- Working with motherboards, chipsets, and expansions
