Where is information that you view on the intenet stored on your computer?
Everything you view on your web browser, ie: internet explorer; firefox; safari etc. Are usually saved in your temporary internet files.
There are several programs out there to clean up these traces of personal data. Once in particular that I use is IOBit's Advanced System Care. Its free and spyware free. It runs periodically in the back ground to clean up privacy traces as well as speed up your computer.
This is not a spam message, I'm just some guy with the right answer for this one. Most things that you view on your computer are saved SOMEWHERE. Even when you delete a file it is moved to the recycle bin first, before it is completely removed. So clean up your Temporary Internet Files and your Recycle Bin. Those are just two of the places. There are just too many specific's to list. I'm sure most of your arent computer technicians like myself. So just go get the above mentioned program and save yourself a head ache.

What should a person look for when selecting a hard drive?
It's quite simple, you need to evaluate your need for storage first and how much this disk will be accessed (from 1 computer or more). If you install losts of software and/or do a lot of video/audio capturing, youll need a large hard drive (100GB or more). Speed is not really an issue here since practicly all newer hard drives turn at 7200 RPM.

On Windows, those are usually referred to as "drivers." On Mac OS X, they are referred to as "kexts", or "kernel extensions." On Windows, if they are not already built into the kernel, they are called "modules."
Where can you buy IDE hard driveS?
One can purchase an IDE laptop hard drive from Discount Tech or Office Depot. Discount Tech is an online store that sells quality products and is very reputable. Office Depot is also reputable and sells name brand items cheaper than most stores.
What happens to the inode when you move a file within a filesystem?
nothing really. the inode contains data about where that file exists within the directory / folder structure. so the inode is just updated with the new location. Also note that this is more or less how it works on all operating systems.
How many IDE devices can a typical mainboard support?
A typical modern motherboard has 1 IDE channel, which can support 2 devices. IDE has been replaced by Serial ATA (SATA), so modern boards have 2 to 8 SATA ports. Older motherboards may have 2 to 6 IDE channels, which could support 4-12 IDE devices.
Difference between CD rom and hard disk?
The difference between a CD Rom and a hard disk is that a CD Rom translates the information on CD's and discs. On the other hand, a hard disk stores data and useful information.
Why YOU choose database system instead of simply storing data in OS?
Operating System (OS) files do NOT hold data for your personal use. Any data in an OS file is used STRICTLY by the OS.
A database system is used for storing data of any kind. A text file is not stored data, so you wouldn't use a database for THAT. But a dictionary of words used in the text file, along with their definitions, could use a database.
Even pics can be stored in a database, and even a list of other files can be stored in a database.

How do you transfer filesfolder from one drive to another drive?
The best way to do it is to right click the original file and select "copy." Then proceed to "My Computer" locate the second drive and open it. Once it is opened right click any empty space and select "Paste." Good luck!
What is the random operating memory?
There is no such thing.
random access memory maybe? RAM
ROM = Read Only Memory, not Random Operating Memory.
Is a optical drive a input device?
It's input I think, not that sure, but I just know that it reads data from a disc and then views them onto the computer screen. :)
Is a hard drive an input or an output device?
It is neither. In addition to input devices and output devices, there are devices called storage devices. The hard drive of a computer is a storage device: it contains the operating system and any data or program files used by the computer.
Although a hard drive both accepts input and provides output, it is not accessed directly by the user in either of these functions. A flash drive, CD, DVD, or external drive are other storage devices or media. In early computers, drives wrote to removable disks as CD burners and DVD burners do today. These types of media-writing hardware are considered output devices.

It's both, or neither, depending on how much of your hardware you choose to define as "your computer."
Since a device is basically something outside your computer that the computer communicates with, the answer to this question depends on what exactly you consider to be the boundary of your computer.
First of all, from the perspective of your computer's motherboard and in particular its central processing unit (CPU) chip, which actually do the "work" of the computer, a hard drive is clearly both an input device (because data can be read from it) and an output device (because data can be written to it).
On the other hand, if you define "your computer" to be "everything inside your computer's case" as much of the general public does, then an internal hard drive would be merely considered part of your computer as a place to store data (similar in this respect to computer memory, but slower), and only an external hard drive (one plugged in to the outside of your computer by a cable) would be considered an input/output device.
People involved with designing computer technology for a living (programmers, hardware designers, etc) tend to take the first view, while people involved with the business of making or using computers (computer repair technicians, computer salespeople, and most of the general public) tend to take the second view. Neither is really "right" -- it all depends on where you choose to draw the boundary between what is part of your computer and what isn't.
Some people that there are three types of devices, not two: "input devices", "output devices", and "storage devices." With that set of definitions, a hard drive would be neither an input device nor an output device, but would sit firmly in the third category, as a storage device.
It's called the 'recovery' partition. Various manufacturers will put recovery partitions on certain computer models and not others. Many (older) models came with recovery CDs or DVDs. Newer models expect you to burn recovery media from the recovery partition so that you can recover a system on a new hard drive if the old one fails. You can also try downloading from the computer company web site and burn it to recovery media.
Difference between hard disk and DVD?
a flash disc can store info such as a project you do on Microsoft or something. While a DVD can only store video.
Where can I buy an internal hard drive?
You can buy any hard drive at your local electronics store and online, there are many good deals online. You will see the performance difference between the hard drives with how much data they can handle in a second.
What is a safe ambient temperature for your computer?
External case temperature should always be below 27*C (80*F), with the best temperatures around 18*C (65*F). Internal air temperature should be around 40*C (104*F), except for heatsinks, which require lower temperatures.
As long as you're using fans, don't be worried until case air temperature exceeds 55*C(130*F). At this point, both fans and passive coolers will be useless, and only liquid cooling will be able to safely protect your components.
These are units of storage capacity, not performance. Hard drives can read and write data faster if the platters spin faster. The number of platters will also greatly affect your read and write speeds. Assuming that both drives spin at the same speed, have the same number of platters and are the same physical size, the 120GB hard drive will be slightly faster. It probably won't be noticeable. In terms of storage, 80GB is often much more than a user will ever need, despite the average drive today being hundreds of gigabytes in size. Unless you have over ten thousand mp3 files, have many bleeding-edge games or store DVD quality movies, the extra 40GB will not affect you at all.
How do you erase hard drive before give it away?
Please what ever you do, DO NOT simply do a format of your hard drive. Reason being, with the right software, anyone can retreive any / all data that is on the drive. People may think that after a format, everything is lost, but this is NOT the case.
Depending on the manufacturer of your hard drive, I would firstly go to the manufacturers web site, and download their own proprietary software, for zeroing the drive in question.
By zeroing the drive, the program writes multiple 0's across every sector of the drive, thus stopping everyone but data recovery companies from recovering any data on the drive.
If the program offers a quick or extended write, imo i would opt for the extended one every time. It does take around 2 hours to complete fully, but you know everything is gone, and its safe to donate. If you opt for the quick erase, it usually zeroes the first and last million sectors on the drive.
Alternatively, you can download a program called kill disk. Instead of opting for the manufacturers solution, this will work on any drive.
Hope this helps.

Yes, but ...
-you will need to remove the 128 MB module and replace it with two PC133 SDRAM modules of 256 MB each. The documented maximum RAM capacity is 512 MB
-you will need to disable the on-board VGA (if any is present) and put an AGP 2x or AGP 4x video card in the AGP slot; AGP 8x is NOT supported
-for a SATAII hard drive, you will first need to add a PCI card with a SATAII controller. So you should have at least 1 free PCI slot.
What are the Negative effects of formatting a hard drive?
The effect of formating a harddisk with the Windows operating system is reprogramming the harddrive into the NTFS file system. This system basiaclly assigns sections of the harddrive to save data most efficiently. The quick form of the format simply erases all the data. In BOTH cases all data will be lost and will never be recoverable for the lifetime of the harddrive.
Why is a hard disk non volatile?
Because any data written to a hard drive will be retained almost indefinitely after the power is removed.
Was there any power going to the tower at all?? Could you hear the fan / drive spinning??
If not, then quickest way, is to check the power lead. If this is working, then it could be the PSU that has gone. If it is, change the psu over...
If you could hear fan etc, then check the lead from the monitor to the pc. Make sure its installed correctly.
Is your graphics onboard, or a graphics card? What colour light was on the monitor?
All of these questions, will help determine the correct answer.
Hope this helps. If I can help any more, please don't hesitate to shout.

How data is stored inside the computer?
They are stored in the form of bits or bytes. More information can be found here:

How do you install an OS on an external hard drive?
Drop the install disk for the OS you want to install into the CD drive and reboot the computer. It sometimes is not that simple. The previous answer only works if the BIOS has been set to read the CD-ROM drive before reading the hard drive. The boot routine in the BIOS (hardware chip) will boot from devices in the sequence that are set in the chip. Depending upon your computer, this sequence may be set to (1)floppy/hard drive (2)CD-ROM/hard drive (3)floppy/CD-ROM/hard drive, and so forth. You are responsible for setting this sequence if it is not satisfactory for your needs. Usually, as the machine is booting, for the first few seconds you will see a message on the screen such as, "Press to enter Setup" or "Press F5 to enter Setup" or some such message. Some less robust machines will give you no indication of what to do or when. If you have your computer hardware manual, it should tell you what key to use to enter Setup. If not, try rebooting BY TURNING THE MACHINE OFF AND THEN ON AGAIN and guessing at the the key by repeating it a single key 2 or 3 times a second during the boot process until the Setup menu comes up. The most popular keys that BIOS manufactuers use are , and , although I have seen some use the bar and the key. None will use the regular keyboard keys, such as letters, numbers or special characters. Once you are in Setup, different BIOS manufacturers have different panels to change their settings. Just follow the instructions. Some use the up-and-down arrows, some use the left-and-right arrows and some use the Tab key to move between fields. They will tell you on the screen. After you have made the changes to suit the sequence where you are booting from, MAKE SURE that you select the option at the end to SAVE your changes! Or you will have wasted your time. Conversely, if you think that you have screwed something up, just don't save it, and start over. At boot time, the computer will now look at the first device in the Setup table to see if the media on it has a boot record in front of it. This is called a bootable device. If it does, then it will boot from it. If it doesn't, then it will go to the next device in the table to try again. It will keep trying until it has exhausted all devices and then just stop with a beep-beep. If this happens, then you know that the BIOS is not set up correctly or yoy don't have bootable media in a drive in the Boot sequence. One word of caution, sometimes malicious hackers may have planted a worm on your hard drive. When you re-install the Operating System, MAKE SURE that you use the option to reformat your hard drive during the install. Some OS's will just do it; others will ask you so that your data can be saved. If you have data that needs restored, I recommend that you back it up to a floppy or other device before re-installing the OS and reload it later. Don't worry, viruses and worms cannot hide in data, only in executables. This might be more than you need if your boot sequence is already correct, but I have re-installed hundreds of OS's, and about a fourth of them have viruses or worms on them and another one fourth of them do not have correct boot sequences. You might be lucky on both counts. Good luck!
