Maximum PC

I've been working on my A+ Certification for a little more than a week and I've been stuck on one question about the AT formfactor, Intel and Binary to Hex conveersions, the book nor the movies available for use have helped much.

I need to know what standards the IBM AT formfactor set and why Intel is the leader in CPU manufacturing.

As for the BInary to Hex the multiple choice questions don't have the correct answer to begin with.

What is the equivalent of "0000"?

a. 1
b. 4
c. C
d. F

"0011"?

a. 4
b. 5
c. S
d. T

The last two choices for "0011" I know are wrong.

Any help will be appreciated.

The first AT class systems were sporting the new (at the time) 16-bit ISA slots. These were exentions of the original 8-bit ISA slots found on the old XT class systems.

However a system with any of the following expansion slots is by definition an AT class system:

16-bit ISA
16/32-bit EISA
16/32-bit MCA
16-bit PC Card (PCMCIA)
32-bit PC Card (Cardbus)
32-bit VLB
32/64-bit PCI
32-bit AGP

The answer to this one is in the new issue of Time magazine.

Simply put, they take in about 34 Billion a year, 2 Billion of which is net profit. AMD, the next largest competitor, doesn't come anywhere close to that.

I may not have been entirely clear on the question but the standards I need to know are more around the position of the CPU, RAM, and expansion slots on the motherboard itself.

Unless I became retarded, 0 in any base is 0

As for the second one, it should be 3, assuming thatyou are using 8421 binary and not some funky coded veresion.

lol im perfect example of HS kid who took A+, i was ready at 16 but held off till 18. unfortunately when i became 18 the A+ cert test had upgraded. but i didnt know they stil lask for those gimp hex code conversions these days lol. honestly the A+ for dummies book is best out of 4 books i read for comp repair and basic networking/printing. my other 3 computer books are 1500 pages and are honestly dumb as hell. they teach more history then actuality.

otherwise simple trial n error and exploring a computer on your own will allow you to udnerstand far more. try the networknig and comp walkthroughs in your studies you'll find that you'll learn mroe that way rather then just reading and memorizing.

Nah your definetly not retarded I just found out that the company that published the materials for the class this year are complete morons about a fifth of the questions I've answered have had either no answer given or two or more of the options were the same.



Ya I've been thinking of getting a hold of the A+ for Dummies ever since I started the class, as I mentioned before the material is pathetic, I may actualy learn some thing from those books than I could from movies very similar to those you would watch in High School drivers ed.

i took a A+ course in high school, was very similar to the way A+ dummy book teaches you. to be honest, A+ exam is nothing compared to what you need to know in the real world of computer repair. err last i researched not really.

what benefits anyone the most is how resourceful you are. its not hard to know an Asus motherboard will require you to goto Asus.com to get drivers, etc.

as long as you know where to get a fix your good to go. god forbid i haveta manually repair something ;-p

and if you dont know how to do something, google it up and find out how to. i offer full service IT solutions. do i know how to do half the **** i do? HELL NO! everytime a customer asks something of me thats new to me, i tell em no prob. google it up asap and get back to them like i invented the ****.

dont worry much about hex I doubt you'll see it very often and if you need there is google to find the hex you need

Thanks for the help everyone, and for those who say A+ isn't important I understand that I'm just takeing it so I can move on to getting a little Novel CNA, Linux+, Microsoft MCP, CCNA, and possibly CompTIA Server+.

Personaly I wouldn't spend much if any time on Novel CNA, Took a course on it in college and haven't seen Novel or the book since.
Most companys are starting to get away from Novel due to a lot of restrictions it has on the user/admin (as of 2 years ago)

Your probaly much better off with Linux and or Unix courses, 90% (figure of the top of my head) of hospitals still use a Unix base system for data storage/access. Another good path is AS400 training as a LOT of companys still use these systems and frequently don't know how to fix them, or have anyone that can program them.

um no pci and agp can also be in atx

Dumbass, ATX is an extension of the original AT specification.

Go do your homework junior, it's a school night.

See Above where I said "32-Bit VLB"

Nobody's mentioned the VESA bus, was that introduced on the AT system as well, or was it later? I'm working on A+ as well btw.

whatever im nto argueign with you now i dont have my A+ book handy ill fuckign school u later

Anytime spanky, try not to let those hands shake with anger too much when you type those messages.

after on the slimline formfactor(LPX low profile extended and NLX), very few vesa buses isa stayed pretty much until pci + agp was released by Intel which is now beign replaced by pci-x and pci express

I cant seem to find anything that supports or disproves my arguement until i can find documentation we are both right,

VLB died with the 486 because the specifications on the bus couldn't electrically keep up with the first generation Pentium chips. It had nothing to do with formfactor.


Here's your documentation:
