  1. Athlon 64s don't have a FSB, there is no northbridge as the memory controller is found on the CPU die.

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

    Athlon 64, FX, and Opteron processors have a memory controller on the CPU die, which replaces the traditional FSB. The bus specifications given here are for the HyperTransport link and memory bandwidth.
    HyperTransport: Not technically a front side bus.
  2. Windows is multi-cpu enabled, allowing it to address multiple cores.

    It depends on the program whether it can multi-threaded and can use more than one core. Programs that are tend to be specialised and in the professional sector such as CAD programs etc.

    Obviously more and more programs will become multi-threaded now that multi-core computers are more popular. I believe Quake 4 is one of the first multi-threaded games available atm.

  3. FSB is only related to Intel CPUs now, as AMD don't have a FSB technically because the memory controller is on the CPU die.

    Bandwidth is how much raw data you can transfer in and out of the memory.

    Like most things greater is better.

    Except for latencies, but please don't ask about latencies because you don't even understand this.

  4. yes i know bu twhat im saying is that i have a 4.4ghz machine cause i have two 2.2ghz cores

    No, because your machine would run like a 2.2GHz Athlon in single threaded appplication.

    AMD have used a speed rating name system from the Athlon XP era, because they were the underdog to intel who was now pushing clock speed as what makes the CPU faster than others.

    As AMD had gone the other route making CPUs more efficent and have lower clock speeds if they just simply called it a 2.2GHz CPU most idiots would go and buy a 3.2GHz Intel.

    So the naming system originally was equivalent to the intel clock speed, so a 3200+ would be similar in speed to a 3.2GHz P4.

    However this has kind of gone out the window now with dual core and Intel moving also over to a performance rated naming system.

    Example, if your 4400+ was twice as powerful as a single core CPU it would be called the 7000+ because the 2.2GHz Athlon 64 is called the 3500+.

  5. PC3200 = 400MHz

    PC4000 = 500MHz

    PC5400 = 667MHz

    PC6400 = 800MHz

    etc,

    You can basically divide the PC number by 8 to get a rough speed in MHz.

    But seeming you didn't actually ask a question I can't say more than that.

  6. Also it would be illegal to try and get into a router that i dont have premssion to do ... if you get where this is going ?

    Then it would also be illegal for you to crack the encryption on the network as well.

    Also if she's forgotten the password and is on holiday its hardly going to concern her at the moment. Wait until she comes home and then use the reset button.

  7. It was a naming convention that was ended in a lawsuit if I remember rightly that decided this.

    HDD manufactures did use MiB, KiB etc. naming but they had to stop because they were basically told to do so.

    So thats why the often print on HDD labels 1,000Bytes = 1KiloByte.

    However since then Kilobyte has been used to represent 1,024Bytes, which makes more sence as everything is based on powers of 2.

  8. If your not interested in computers at all but want to move to linux rather than windows then go for ubuntu.

    If your interested in computers start off with a fairly big distro which has excellent support but isn't too hard to get into.

    I'll recommend Suse and Fedora Core.

    As for information then you can usually find everything you'll need in the distros documentation, if not then have a look around on the internet by using your favourite search engine. There is plenty of information about, you shouldn't need to buy any books.

  9. I have a dsl connection and i used to recieve normally about 6000 bytes per day but now i seem to have been downloading things without doing anything.

    Doesn't mean much without a contexted, also I don't think you mean bytes.

    Run AVG virus scan with the latest definitions.

    Run CCleaner.

    Run Spybot S&D with the latest definitions.

    Install a free firewall and set it to notify you everytime a program wants to access the internet.

    Can't say much more than that without information.

  10. I'll admit I don't know much about them, but isn't the archtechture much better than the standard intel/amd stuff? I remeber loads of scientists complaining about the Apple shift to intel because they were using macs to do horredusly complex caluclations for things like partical acclelorators. And the intel kit just wasn't up to the job.

    I wouldn't say the archechture was much better than x86/x64 processors, but they are certainly better for different things.

    Thats the artical comparing the G5 to the new Mac Pro, it'll give you an idea of how those architectures different.
