    Just got through the CPU chapter of Mike Myers A+ book and I have to say that it was a long read!

    At the end of chapter questions I got 8/10 but guessed 2 of them right.

    I've no idea how I'm supposed to remember all the different sockets/names and Cache sizes..

    I also got confused with the functions from CPU -> MMC (chipset?) -> RAM (I got the basics, it's the names of certain parts that confused me)

    Totally need to re-read the chapter again!!! :blink

    Read the book
    Do some exam prep questions
    Read the book again
    Get the A+ Exam Cram
    Read that
    Do the exam

    Which all is the same as
    Till the soil
    sew the seeds
    Water
    Weed & tend
    Harvest

    Stick at it

    Even though the A+ is an entry level cert, it is by no means easy, especially if this is your first professional cert. Take your time, don't rush, it'll come to you :)

    Like Spilly said "Rome wasn't built in a day!"

    It's funny because in real life, techs don't have all of that stuff memorized...just the information they tend to use on a regular basis. The rest they can look up if they have to.

    All you can do is your best and realize that there won't be dozens and dozens of questions on the test having to do with CPUs...just a few (probably). Don't sweat the small stuff.

    Is the Chipset the MMC or the CPU+MMC+RAM together?

    I can't seem to find in the book whether the Chipset is the MMC or CPU+MMC+RAM?? anyone help?

    I'm not 100%, but I always thought that the chipset was just the North and South bridge, and all their related functions. The CPU and RAM are not part of the Chipset.

    Well, all the way through the chapter Mike Myers never mentioned the chipset. When I finally got to the end of chapter questions, it asked:

    What is the function of the Address bus in the PC?

    A. The address bus enables the CPU to communicate with the chipset.

    B. The address bus enables the memory controller chip to communicate with the RAM.

    C. The address bus provides a channel for the flow of data and commands between the CPU and RAM.

    D. The address bus enables the CPU to access registers.

    Answer = A

    The chapter only spoke about External data bus, Address Bus, Memory controller chip and RAM.. No mention of Chipset so naturally I chose B and it was wrong :rolleyes:

    From what you you say, it appears I'm wrong. Although the address bus surely communicates with every device on the machine, and I would definitely say that the Hard drive is not part of the chipset!!.

    This is one that Tripwire should know seeing as he has written a book on the topic. C'mon Trip, put us out of our misery!!

    It does mention somewhere in that chapter about the chipset but says it will talk about it in greater detail in another chapter which it does.

    There are a few chapters where you have to ahead then go back to before doing the chapter review questions.:blink

    Thats what I thought..

    The Chipset that you described control PCI, AGP as well. I have been looking online for Chipset and I only ever get this result - Norther and southern Bridges etc.

    Gawd I'm so "new" :oops:

    When you find out, do me a favour and let me Know. Its always good to reaffirm (I hope) what you know. :D

    As far as I understand it when it talks about the chpset all it is meaning is the Northbridge and Southbridge.

    The Northbridge helps the CPU and RAM work together, the Southbridge handles stuff like graphics cards and hard drives.

    The address bus just links the chips together

    Is the northbridge chipset a.k.a as the MMC (memory controller chip)?

    Yes the MMC is the Northbridge.

    So it goes something like this: CPU, MMC (Northbridge), RAM,

    Then the Southbridge, Input, Storage, Output all connected by the Address Bus.

    Hope this helps

    Yea thanks.

    I knew it was CPU -> MMC -> RAM
    It was just the Chipset question that confused me..

    A chipset is a somewhat difficult concept to wrap your brain around...at least it was for me. Fortunately, Googling "chipset" comes up with tons of useful information. Don't just stick with the Meyers book. It's good...really good...but it isn't the only source of information in the universe. Here are some search results:

    http://en.wikipedia.org/wiki/Chipset

    http://www.webopedia.com/TERM/C/chipset.html

    http://searchsmb.techtarget.com/sDefinition/0,,sid44_gci211781,00.html

    This one is actually a manufacturer's list of chipsets:

    http://www.motherboards.org/mobot/chipsets/

    The links above won't tell you everything and it is a worthy subject. See whatelse you can learn about chipsets and post the information here. This is a really good thread and the sort of topic CF was made for.

    BTW I dont think your gonna have to remember CPU speeds etc for the A+ exam.

    I am going through the book for the second time highlighting key points

    you're lucky they don't ask you to remember all the CPU code names. i tried making a list once, ending up gaving up after about 50 lol
