Is 255.255.255.254 a vaild subnet mask?
It's valid and it's called a noncontiguous subnet mask since the 16 bits for
the subnet mask are not contiguous. The RFC's, however, recommend against
using noncontiguous subnet masks.
How do you stop your PC from crashing?
5 Ways to Stop Your Computer From Crashing
Unfortunately, marked improvements in computer reliability have not eliminated the fact that computers do still on occasion "freeze" or "hang." Or even worse, "crash". However, you can take measures to minimise if not eliminate PC crashes and freeze ups. Here's how.
1. Upgrade to the latest operating system The stability of a PC's operating system is the key to computer reliability and availability. The code used to build the latest versions generally improves on the code woven into earlier ones.
That's usually the case with Microsoft Windows. A test report from eTesting Labs Inc. shows that Windows XP Professional is significantly less crash-prone than the now two generations older Windows 98 Second Edition.
2. Take virus protection seriously New computer viruses go into circulation on the internet every day. A virus can erase or corrupt files on your hard drive and trigger a computer crash. Be sure to:
-Install antivirus software and keep it updated.
-Use caution when opening and installing files. Ask yourself if you trust the source of the file before taking any action.
3. Keep your software up-to-date Software companies continue to make improvements to their products after they're released to the public. These updates are packaged in the form of service packs.
Use the Windows Update (US link) feature to automatically download the latest service packs and critical security patches. If you're already using Windows XP, be sure to install the latest service pack available. To ensure that Microsoft Office System applications such as Word, Outlook and Excel have the latest security updates, visit the Office Update site.
4. Use care when installing new programs or drivers Computer problems often arise after adding new programs or drivers. Drivers are small programs that make your printer, graphics adapter, sound card and other hardware devices work with your computer's operating system.
If you have multiple new programs or drivers to install, install one and then make sure your PC is operating correctly before you install the next one. This way you can more easily identify if a particular program has caused a problem.
One advantage of running Windows XP Professional on your computer is that unlike Windows 2000 and Windows 98 , it has built-in tools to rescue your PC from programs that make it behave badly.
5. Provide surge protection and backup power PCs house voltage-sensitive components that a power surge can easily damage. A spike in the electrical output from a wall plug will at minimum shorten the life of your computer. It could also crash and destroy your system, taking all your data with it.
Surge protection devices work as a buffer between the electrical supply in your building and your PC. They are fairly inexpensive especially when compared to the cost of replacing a PC. For a bit more money, a device called an uninterrupted power supply (UPS) provides surge protection as well as a back-up battery to keep your PC running in the event of a power outage. This keeps you from losing data you haven't saved, and allows you to keep working for at least another 10 to 15 minutes.
A slow computer can be as frustrating as one that crashes or freezes. You also might consider adopting a regimen of regular system maintenance. Defragmenting your hard disk, checking the hard disk for errors and deleting temporary files can improve system speed and performance. Using Windows Scheduled Tasks feature is a simple way to automate your PC maintenance chores.
In some cases, the CPU or the video card could be overheating. So check the CPU, GPU, and case fans to see if they are working and adequate.
What keystrokes did you use to access CMOS setup?
It varies by computer/motherboard manufacturer. If it is a system from a well known company like HP, Dell, Acer, etc, you can look on their web pages and generally get the answer.
Alternately, many times you can press esc when the first splash screen appears and it will show you the actual DOS boot process. If so, look at the bottom of the screen on the left hand side for message on what key to press to enter setup. On my particular system, you have to press F2.
How can you format a computer to make it like it was when brand new?
A format will erase EVERYTHING, so if you have an external hard drive, backup everything in there. It will also erase your operating system as well. If you reformat, your computer won't have an OS to boot from.
If your computer is manufactured one like DELL/Compaq/HP/Gateway, your computer may have come with a system restore disk that will do the reformat for you and install everything exactly as it was when you brought it home. If it doesn't come with this disc, many times you can buy it from the manufacturer. If your computer is an Acer, there is an option using Acer eRecovery Service to restore it to the Factory Defaults. Your Acer may also have come with a recovery disk, which you can restore using using the eRecovery Service.
1. Insert your manufacturer restore disk or Operating System disk
2. When you initially turn on the computer enter the boot menu, change the boot sequence to have the CD-ROM boot first rather than the Hard Drive and follow the instructions.
You can use programs such as Active@ KillDisk found at killdisk.com These programs are available in case you don't have an Operating System disk available to you or you are throwing your hard drive away and don't want your data out there possibly in the wrong hands. Boot n Nuke is another piece of free software that can format and erase your hard drive over and over again.
1.Go to dban.org 2.Click "Download" 3.Click "for CD and DVD media" 4.Burn the downloaded file to CD/DVD with an ISO burning software like infrarecorder which is free to download at infrarecorder.org. 5.Insert the disc and reboot the machine. 6.If your PC is set to boot from the CD/DVD drive first, it should boot dban. If not press F8 or F12 then select DVD drive. 7.Your PC should load the disc and then follow the instructions on the screen. Formatting may take some time but it is well worth it because it erases data a few times to a standard where no data is recoverable.

What Factors can affect the proper operation of computer equipment?
There are many factor that can affect the proper operation of computer.The hardware compatibility is the most important factor and then comes the compatible soft-wares.Temperature and humidity also affect the computer's working .The high temperature would lead to hardware failure.Humidity might lead to statics electricity formation on the the mother boards and other hardware.
My hp laptop's battery is no longer charging?
Laptop batteries usually have 3 maximum 4 years (sometimes even less) of life. And at some moment it has to be just replaced.
How do you delete duplicate pictures from your computer?
Run a search for image files (Start, Search, Files or Folders, Pictures, Music or Video).
Click on each file that turns up in the search, check the contents, then delete all or some as required. (There will be a lot of them.)
That's to free up space.
If you want secure deletion, the only safe way is to use an electronic shredder to overwrite the hard drive with several layers of random digital data. This will make it difficult (but perhaps not totally impossible) to retrieve anything that was on the drive. It will also require that you re-install the operating system and anything else that was on the drive. We're talking nuking the hard drive, here.
The reason such a draconian step is needed is that deleting a file does not remove it. It just allows the computer to utilize that space if it is needed. Even if your data is overwritten, a forensic examiner can often recover data from underneath the overwrite. Also, your computer hides copies and temporary files all over the place. The only safe way to get them all is to shred that drive (multiple overwrites).
If you decide to go that route, plan on it taking several days if you have a big drive, as the entire thing will need to be overwritten at least seven times, and preferably more. Another route is to remove the drive, smash it throughly with a hammer, then throw it in a fire for a couple of hours. That will render the data absolutely un-recoverable. In the long run, that's probably a better route, because you'll end up with a brand-new drive in your machine.
Can you use a server as a normal PC?
Yes, you can. Just install whatever operating system you're wanting on the server and use it like normal. I know of a few people that have done this and I want to try it but I don't have a couple thousand dollars to blow on a server.
If you are fortunate enough to come by a SERVER UNIT, then all you have to do is wipe the hard drive(s), Format it/them and install your operating system onto the primary hard drive. Check the BIOS to determine this, make sure you have enough space...at least 10 Gigabytes, which a SERVER should easily have...and set the primary drive to boot up first...easy.
What can be the problems when a computer boot but does not turn on?
I am going to assume that you meant the computer turns on, but does not boot.
If the computer does not boot, it is probably because there is a problem with the operating system. Another option could be that the computer does not have a hard drive or the hard drive is undetectable by the computer.
Are there any connectors provided by the power supply that your system isn't using?
As a general rule, there are several extra power connectors of varying types on the power supply. This allows for expansion with various drives and devices.
Some power supplies don't provide the serial ATA (SATA) connector. In which case, you can use an adapter power cord to accommodate SATA hard drives.
If your computer turns on but it doesn't show on the screen what can it be?
There are a few possibilities:
1. Loose, unplugged, pinched, or failed video data or power cables.
2. Incorrect BIOS settings.
3. User error. A multiple video card computer may be sending data to the monitor you are not hooked up to.
4. Incorrect brightness settings on your monitor.
5. Failed/failing monitor hardware.
6. Failed/failing video card hardware. This can be part of your motherboard or a removable card.
7. Failed/failing power supply or supplies.
8. Bad operating system driver. However you often will see bios messages before going black on system boot.
9. PC and/or external monitor power supply damaged/malfunctioning.
10. Power supply not sufficient for all attached internal devices.
11. Dirty power. Too many spikes and brownouts.
12. Short in case. Generally caused by an extra screw or other debris in whitebox computers. Sometimes misdiagnosed as a bad case.
13. Malfunctioning or shut off UPS or surge strip, if attached.
14.It has no battery.(laptop)
What was the average cost of a computer in 2010 in US dollars?
It could be anywhere from $100 to $800000000 depending on OS, manufacturing company, where it is sold, and many other factors!
Really, if you want to get one price, you'll have to be a lot more specific. i.e. "What is the price of the latest(in 2010) (Manufacturing company)(Computer OS) at (Store Name)?"
Are hard disks are considered Volatile or Nonvolatile storage devices?
the hard disk drive is considered a nonvolatile storage device
Why would your computer automatically restart after being turned off?
All Windows versions have the same function. From the Start button, select menu/programs/accessories/system tools/system information, then click on the tools menu and select system configuration utility.
When the program opens, you'll see an advanced button on the bottom right corner. Press it.
Make sure you have disabled fast shutdown (CHECKED). Press OK/OK. If it prompts for restart, don't do it, you don't need to. Press cancel on that screen and then shutdown like you would normally.
AnswerI have found I think the answer to that question, although I haven't had the time to test it since it is on a friends computer using xp pro. but you can if you like. go to the bios and check your modem if you are on a phone line and disable the auto start feature...You may find it only restarts when a call comes in... AnswerThe bios settings turn the computer on automatically. I actually have mine set to turn on automatically in the morning before I get out of bed so it's already on when I get up.Watch what you see on your screen as you boot up the computer and do whatever it tells you to do to boot up in bios (typically by hitting the F2 or Del key). Once in bios, go to the power section. In the power setting you should see something pertaining to the modem. If you do NOT want it to power up automatically, choose the Disable option.
If you DO want to power it up automatically, it will also ask for a time (day of month, hour, minute). If you set the day as 1, for example, it will power up on the 1st of the month at the time that is set. If you set the day of the month to zero (0), it will power up every day at that time.
AnswerTry turning off the hibernation feature that can be found through control panel->display->screensaver tab->power->hibernate and then turn off the hibernation feature AnswerOpen your registry: and find the key PowerdownAfterShutdown and set it to "1" to power off the computer at shutdown, or "0" to reboot. Here is the path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon If you don find it, create it(REG_SZ (String Value)) restart windows AnswerAll are very good answers. How are you shutting down your computer? Do you go to start shut down and then press ok or do you hit alt + f4? First I would check to see if my PC was set on restart in the shutdown window just before you click ok. If it is change it to say shutdown. Then I would try some of the other answers but they take a good knowledge about computers if you mess up. Hope it helps. AnswerFirst go to your start menu and then right click my computer and click properties.click on advanced tab and then under startup and recovery click on settings..
then under system failure uncheck the automatically restart....
AnswerLook in your bios for a Wake on Lan option also.What is the purpose of the northbridge?
It depends on the type of CPU used. Originally, the northbridge chip served as a memory controller, AGP bus controller, and system bus. It interfaced with the CPU, the RAM, and the southbridge chip. The southbridge connected to about everything else. But most of the northbridge functions are now done by the CPU in many computers. The memory controller and sometimes even graphics are in the CPU these days.
1 What is an example of e-commerce?
An example of electronic retailing is a retail store allowing customers to shop online. The only way this can happen is through the use of electronic devices and the Internet. Paying for the merchandise through the use of credit cards is also a type of electronic retailing if that is the only source of payment accepted.
How do you recover lost system restore points?
You can't. If they are still on the computer, you can open system restore and click "Choose a different restore point". Then click next, and in the bottom left hand corner of the windows, click "Show more restore points". If that doesn't work, they are gone. The OS will automatically delete old restore points.
What functionality is lost if the power connector from the CPU fan has only three pins?
PWM (pulse width modulation, which controls fan speed in order to reduce the overall noise in a system.
Just get CCleaner from Poliform. Its FREE and the best cleaning software out there. It also has a Registry fixer and it will make your computer faster.
Answer:
Disk Cleanup (cleanmgr.exe) is a computer maintenance utility included in Microsoft Windows designed to free up disk space on computer users' hard drive. The cleanup process firstly involves searching and analyzing the hard drive for files that are no longer of any use. It then proceeds to remove the unnecessary files, freeing up disk space on the hard drive. There are a number of different file categories that Disk Cleanup targets when performing the initial disk analysis:
Compression of old files
Temporary Internet files
Temporary Windows file
Downloaded Program files
Recycle Bin
Removal of unused applications or optional Windows components
Setup Log files
Offline files
