Hi I've just bought a CD Course from a well known company, in it there is a lot of focus on how CPU'S work i.e how the address bus works, the MMC function and so forth!!! even now there questions on binary in the new Comptia exams...... Why on earth do we need to know how the address bus connects with the CPU and how to count in Binary to repair and troubleshoot P.C.'s ???

Has Comptia finally lost it??

Because not everyone who embarks on the A+ have worked with computers before.

 

yeah I agree with you, but like I said, do we really need to know the intricate and complex details of how a cpu works in order to repair a pc????
I personally think not......CompTia are making thier course objectives far to complex for the real world....

 

At times, the most valuable steps to help resolve an issue, is usually the stuff you least expect or find unimportant at a previous time.

 

I dunno. When I was doing my A+ I actually found getting to know that stuff kind of useful. My feeling is that if you actually have an understanding of what's physically happening (or supposed to be happening) 'under the hood' then you're probably going to be able to troubleshoot any problems that much more successfully (and quickly)

 

but when do we repair a cpu?

 

I thought some of the material was pointless but looking back I realise it smoothed over many many gaps in my knowledge. I'm glad of it really

Just because you don't perceive it as useful doesn't mean it ain't. It is a ball ache memorising tables of stuff though when you get the feeling you may never need to reel off the size of the L2 cache on an AMD k6-2

It didn't have L2 intil the k6-2+. See I used some of it!!

 

I've never repaired a CPU, but I found myself learning loads doing the A+. And a lot of it wasn't on my degree when I was doing that.

I already had 3 years or so IT experience when I did the A+, and although there was plenty I did know, there was a fair bit I didn't know.

 

If you get a job as a hardware tech then you might have to.

personally I believe you need to know how the address bus etc works. Learning about computers and IT is a long process and if you want to learn the advanced stuff you must first start with the basics as is true about nearly everything else in life.

BTW the binary will help prepare you for subnetting for the network +

 

This.

Having an understanding of the various Buses etc informs a lot of what you'll do as a tech, you'll find knowing CPU features useful as well as there is software out there which will only operate if a particular feature is available. Knowing these things will make you a better tech, trust me.

The Binary will be helpful for other things as well as subnetting, remember everything your PC does is actually done in binary so your bound to come into contact with it at somepoint.

 

Considering your multiple replies on this forum and another one that I frequent, it sounds like you just want people to agree with you that you won't need to study it and that CompTIA has indeed gone off the deep end. I hope that I am wrong about that, and that you truly do want real answers, even if they differ from what you had expected.

The question is this... do you want to continue to resist learning this information, despite being advised that the information will likely be beneficial to you... or do you want to listen to the truth that is being given to you by people who are already in IT?

Study it, bro. It won't kill you, and it just might make you a better tech.

 

Ultimately, does it matter? The fact is, it is on the syllabus. Assuming you actually want the cert (and I have to assume that you do since you are studying it), you either get on with it, or choose to not study that material and take your chances with your money on exam day.

The choice is yours.

 

ok thanks for all your advice.... guess I better knuckle down and start learning it....

 

Its one of these things.

In nearly everything you have to learn there is stuff that you dont feel relevant, but it is good to have a steady foundation to start of on.

 

And that is exactly it: it is the foundation upon which the rest of your knowledge is built. For example, years from now, you'll know what it truly means when they say "a 128-bit processor" - you'll KNOW why that's important and what benefits it will provide.

 

This bit got me excited for some reason

 

It'll have been the number that did it twisted:
