Which description most accurately describes the input-output model?
a model of interactions between different sectors in an economy
if the motherboard is designed for the case fan you are using its best to plug it into the motherboard, this will free up a spot on the power supply. Otherwise as long as the voltage and amps are the same it doesn't really matter.
If you try to plug it into both you will double the power of the fan and very likely fry the fan.
What is a compute bound program?
In general, applications are I/O bound or processor bound, meaning that the process is waiting for either I/O or everything else is waiting for the processor to finish working.
With the speed of today's CPU's, most modern applications are NOT processor bound, meaning that we're typically not waiting for the processor to finish what it's doing. Usually we're waiting for some kind of I/O process to complete.
Many times we're I/O bound when we have insufficient memory and the operating system has to "swap" an application or parts of an application out to swap space (virtual memory) on the disk. Moving an application into and out of virtual memory becomes very time consuming and is often the reason people are advised to add more Random Access Memory (RAM) to make the computer run faster.
What is the difference between a DVDplusR and a DVDdashR?
There is no physical difference between a DVD+R (DVD plus R) and a DVD-R (DVD dash R), but there are technical differences between the two formats. However, almost all new DVD writers can record on both formats, so the differences are not an issue for most people.
The DVD-R is approved by the standards group 'DVD Forum' while the DVD+R is supported by the 'DVD+RW Alliance'.
The main functional differences between DVD-R and DVD+R are:
1) the DVD recorder's built-in defects management
2) the way the recorders format and rewrite DVDs
3) the price
More specifically:
DVD+R can instantly eject. It can partially record on television and partially on a PC. It has background formatting where you can be recording on the formatted part while it is still formatting the rest of the DVD. DVD+R has the ability to edit filenames, playlist, and movie and song titles.
DVD-R has to be formatted before you can record on it. Formatting has to be completed before the DVD-R will eject.
What is the most powerful graphics card?
The nvidia geforce 8800gtx has been superseeded by the nVidia 9800GX2 as the most powerful graphics card (March 2008). It is two 9800GTX's sandwiched together with a single heatsink in the middle. This in turn makes this a very hot GPU and requires good case cooling. It is also very, very expensive.

What is the best Linux distro for wireless?
SUSE and Red Hat are the two most common. I just loaded SUSE 9.3 on my wireless laptop and it's solid. I'm not too fond of getting "the latest and greatest" since there are often problems associated. I had tried SUSE 10.3 and had a lot of problems so I found an older version. It worked great.
I don't know much about Red Hat except that it's also very popular so it must have something going for it.
How many MB is equal to 177000 kb?
One Mb is equal to 1000 kbs.... so 117 Megabytes (Mbs) or .117 Gigabytes(Gbs)
Which is faster among pci and USB?
A conventional PCI bus (not PCI Express or such) at 64bit @ 66mhz has a max transfer rate of around 533MB/s. That being Megabyte, not bit.
USB has a transfer rate of 12mb on regular and 480 on high-speed mode. That is megabit, which is much less then MB per second.
PCI in this case, compared PURELY on speed, is much faster.
Why is it important to select and use the best tool when servicing computer hardware?
i wonder how that could be... ? i mean, would you use a crowbar to fix display issues on your PC? i thought you where suppose to...
heh, just messing with ya
it's important to select the proper tool when dealing with hardware or software because, well, it'll make your life easier while you diagnose/fix the problem. think about it, just as pc technicians use anti-static wrist straps to prevent ESD (electrostatic discharge) so does a builder uses a hammer to drive a nail in. using the right tool for the job is your best bet or would you rather be stuck on the same thing for hours?
