List five form factors mentioned in this lab that you should consider when selecting a cooler?
The size of the cooling device, The heat emitted be the component you want to cool, The temperature at which you want the component to be, Do you want to overclock?, and What method to use for cooling the component (ie Heat-sink or water cooling)
How do you adapt a pcmcia card to USB?
external USB PCMCIA adapters are commercially available, such as this http://www.quatech.com/pdf/u142-e.pdf , but they're not cheap, and are sometimes limited to the type of PCMCIA device they can attach to.
Unless you have a "special" PCMCIA adapter that you need to reuse, then it may be more cost-effective to look for a USB device that performs the same function. i.e. USB 3G/HSDPA modems, LAN adapters.
What happens in the processing stage?
A program has three stages: input, processing and output. Input brings data into the program, processing causes whatever manipulations the program will do to occur, and output presents the manipulated data to the user. Given that, only in batch-processing programs (like the databases that do billing for phone companies) will you see a discrete "processing" stage. Programs you interact with do all three stages simultaneously.
What is the mainframe computer size?
This has varied from 40 standard telephone switching panels covering 3 sides of a long rectangular room (ENIAC in 1946), to an entire floor of a four story cinder block building (Sage AN/FSQ-7 air defense computer in early 1960s), to as small as a couple large freestanding electronics cabinets (IBM System 360s from 1964 to 1971).
There was no fixed size.
How do you determine a PC bus type?
Click Sart or the Vista Orb ( Xp or Vista ) Then in Search type: System Information.
Click on it.
When it appears on the screen, click on components.
Then click on USB
There should be a couple of sentances
The fist sentence should say (for my one):
Standard Enhanced PCi to USB.
And that's how.

How do you find your physical Ethernet adderss?
You may be referring to the MAC address. The easiest way is to open a DOS prompt (select RUN from the Start Menu & type in cmd) and type in ipconfig /all and press enter.
Under the appropriate ethernet card there will be physical address: and be in the format XX-XX-XX-XX-XX-XX-XX-XX (These instructions are in MS Windows)
It is not practical to attempt a full tutorial here on Windows Console commands (formerly known as MSDOS). This page summarises the essential commands and techniques, to enable you to get started with SNDAN and, maybe, develop a taste for what can be a very fast way of working. It is intended primarily for those who haev notused a Console window before. Terminology. There is a number of equivalently meaning terms used to refer to a Console window. It may be a 'DOS session' or a 'DOS window' (where DOS may also be 'MSDOS'), a 'terminal window,' the term most used in Unix systems such as Linux, a 'command-line window', or a 'command shell' (from the notion that it acts as a safe and convenient 'shell' around the Operating System's main commands). All these terms mean essentially the same thing, which is called here a "Console window". There is one linguistic difference. Windows Explorer (and Windows documentation generally) refers to files and 'Folders'. The latter is supposed to be a 'friendly' word. In a Console session, however, the older term 'directory' is still more widely used, and is the basis of many of the command names.
What is the Largest 8 bit number?
Largest 8 bit unsigned number is 11111111 binary thus making 255 in decimal.
What is an input device on which you key in or type data?
The device used to key in data or communicate with the computer is called a keyboard. The keyboard can either be wireless or wired to your computer.
Are movie DVDs being developed which cannot be copied in order to stop piracy?
Of course the new protection systems will be arriving with HD DVD and blue ray discs. They call it dynamic protection and is considered difficult to break.

AnswerThis question and related questions are fairly generic. The solution is the same for most brands of computers and video cards such as pci, pci-e 8x,16x (pci express), pci-x (and older and obselete standard).Solution steps:0. Make sure you have the latest version of the video driver from the vendor that made the card. Often the CD that shipped with it is a year out of date or more. If it came out before xp sp3 or vista sp1 the drive many not work right. So download the latest.
1. Turn on PC and enter the BIOS / CMOS by tapping the del key or delete key or F2 (Intel) or F10 (HP Compaq) F12 (Dell?).
2a. On most systems you do not need to disable the onboard video card. Open your PC, add your new video card and move the monitor plug from the onboard video port to the video card you just installed. On boot the computer will sense that there is no monitor connected to the onboard video port and will disable it or at least will redirect the screen output to the newly installed video card. However, once windows has been installed with the onboard video card it may be marked as the "default" video device and limit the ability of games to perform properly. Games also may detect the onboard video card and quit because the onboard card is not fast enough. If you are still having problems perform step 2b.
2b. Turn off the computer, move the monitor plug from the onboard video port to the video card you just added. Repeat step1 then navigate to "onboard devices", for Dell this will probably be labeled Video or Display Settings. Disable onboard video. Now save the setting you just made in the bios by pressing F10 or choosing the save from the menu, you may have to press ESC key to get to main menu. Now boot windows and install the drivers for your video card.
3. in extreme cases after following step 2b if you many have to reinstall windows with the onboard video card disabled so no drivers are ever installed. This is a "best practice" for serious gamers and results in the cleanest install. This way the onboard video card is never seen by windows and no drivers are present. Remember, driver files are usually left behind and are not removed by the uninstall. If you arn't ready to wipe off your system you could unplug your hard drive and plug in a test hard drive and perform a clean install windows (don't use the recovery disk) and test out if this yields better results).
Last resort: If you are still having problems with the uninstall, go into the device manager in windows and double click on the Intel video (or onboard video card), at the bottom of the page that comes up is "USE THIS DEVICE" choose instead to not use this device. Restart windows and see if this helps. Also make sure you have the most up to date drivers for the video card you are using and if so, right click on your desktop and choose properties and make sure the resolution and color depth are set to the correct settings, like 1024x768 32bit
Optional Reading:an example of an unusual and complex onboard video graphics driver situation:
Updated: 10-03-08 This system described in the next paragraphs is a "bare bones system" for oem's resellers / value added resellers. The bios is limited and does not have the ability to disable the onboard video card. Disable device is not an option, unfortunately, in windows 2000 sp4.
I am tasked with a project at work with an old samba PC (not to be confused with Linux) It's actually an FIC (first international computer) branded motherboard model VC37 revision IEM42 0601 with integrated Intel 845 graphics and the uninstaller fails to uninstall the driver both from the control panel and the actual driver in device manager. I added an old pci video card but the dispay is all wacky. In the bios turbo mode is disabled but there is no option to disable the onboaard video. Although the system correctly uses the addin video card the picture is a mess. Reloading the OS is not an option.
The uninstall for the Intel drivers fails to actually uninstall the drivers. I performed a manual "uninstall" by removing the entries in the registry and deleting the files used by the video card in c:\winnt\system32 and \winnt\...\drivers but that didn't help either.
A co-worker discovered that the newer asus 945G computer that we are trying to port the image to is setup for ACPI and while the older samba 845 is not, it is set to "standard PC". We now believe this difference is the core of our problem.

How do you troubleshoot error unmountable boot volume stop 0000000ED?
To troubleshoot the unmountable_boot_volume 0*000000ed (aaaaaa,bbbbbbb,cccccc,dddddd,eeeeee) we have to follow the following steps:
1)Reboot the system and enter into the bios by pressing the f10 and del.
2)Insert the windows xp professional CD and change the booting order from the CD-ROM.
3)Reboot the system, Press R to enter into the recovery console.
4)Select the partition and enter the administrator password.
5)Type CHKDSK /R /F to run the checkdisk command.
6)After finishing restart the system and enter the bios and change the boot order to boot from the harddisk and restart the system.
7)Remove the CD, check thesystem boot.
8)Run the disk defragment.
9)Run the antivirus for viruses.
8 Starting with the easiest procedures list two things to check if your PC does not boot?
Is this a question, or a quiz?
Two things to do first:
Rule one, remove ALL cards/peripherals except video if there's no on board video system.
Boot into safe mode.
If it boots and shows a video screen, then add one peripheral back at a time.
In general, simply booting into safe mode with all peripherals installed, usually allows a system to run. The device manager can then be used to check/configure/disable peripherals. Look for red "X"'s or yellow "!"s and see what's wrong there.
If using Windows or _nix, the OS should auto-detect all hardware.
Maximally, you can remove all cards, unplug all IDE devices as in CD/DVD ROM drives, floppy drives, and hard drives, and see what POST codes or errors come up.
If the FDD I/F and floppy drive are functioning, try booting with an ordinary or better yet, a diagnostic DOS boot floppy and perform basic system tests like a RAM test and tests of other parts of the system. Most systems come with diagnostic floppies or CD-ROMS.
Remove all RAM except one stick (or two if you have RDRAM)... Sometimes incompatible RAM will prevent a BOOT and putting in only one stick, or two RDRAM sticks of the exact same type can eliminate compatibility issues. You can also try individual sticks of memory from different manufacturers in case some RAM is not working with the system.
Basically remove as much hardware as possible to see if the system will POST, then add things back one at a time until it again fails to POST.
If there are still problems, clear the CMOS RAM using the motherboard jumper, if available, or if an old system without one, remove the battery for 15 seconds or so.
Check the CMOS battery. Is it dead? Even then, the system should POST and throw up an error alerting you that CMOS memory has been lost, but would still POST with all the BIOS settings lost and reverting to defaults.
Many systems, have three CMOS jumper settings: Normal, Clear CMOS, and "recovery mode". As a last resort, though very unlikely, the BIOS might be corrupt. Using this as a last resort, putting the jumper into "recovery mode" will force the system to boot from a BIOS install floppy and will replace the BIOS with a new copy. This is highly unlikely, however, to be the cause of the problem and is not recommended for troubleshooting.
If the system still fails to boot, then something major like the power supply or CPU or other motherboard component is dead.
Swapping parts would be the next step. Start with the power supply. If you have a CPU of the same model from another working computer, that can be swapped out as well.
Try to find out what the BIOS is complaining about by writing down the beeps if they occur, or on-screen errors. If you get a video screen with errors, the system is basically functioning. If you get no video and only beeps, the number of beeps will indicate a specific error which would have to be looked up in the manuals or at the manufacturer's website. If there's no beeping, drive activity, and everything is just dead when powering on, except the fans, there could be a dead CPU or other major chip, or possibly some of the power supply outputs are bad. Finally, if NOTHING is running, including fans, then definitely the power supply would be the first thing to check. The power supply voltages would have to be measured with a voltmeter and verified.

How do you draw on the apple echa sketch widget?
well you just try your best to draw an apple with your echa sketch drawing tool
Will 140MB fit on a 1GB drive?
Because 140M is megabytes which is much less that 1G (1 gigabyte) = 1024M, it will fit about 7 times. Anyway usually the 1G drive is not usually guaranteed so it's only approximate value. FYI: M = MB = megabyte (1 * 2^20 bytes) and G = GB = gigabyte (1 * 2^30 bytes)
you've just invented the word loptop and linked it to the computer context, though Laptop (not LOPTOP) is a commercial brand for a notebook. Google it. You should know it does not harm you to try researching a little bit before asking easily answering questions. LOOSER
