What values are held in CMOS for hard drive?
Size (head, cylinders, sectors)
Can you bring back things you have erased on your computer?
If you are running windows this is easy if you have not permanently deleted what you want.. Just click on the recycle bin and you will see a list of everything you have deleted. Click on what you want to restore and click on "restore this item". It will go back to where it was when you deleted it. If you have emptied your wastebasket it will be really hard to get something back. If it is something really really valuable you might be able to pay an expert to retrieve it from your hard drive because you see, when you "permanently" delete a file, all that is really deleted is the address of the file in the directory. Until another file is written over it, which happens somewhat randomly, it can be recovered. This is why old hard drives should be reformatted or destroyed when a computer is sold or retired if it held sensitive information.
Where are the most frequently used files held?
I think you are referring to what is called cache memory. (rhymes with 'cash') Cache is a portion of computer memory reserved for frequently used information, so that the information can be accessed more rapidly than retrieving it from the hard drive, or from the 'regular memory'
How do you delete a file from hard disk?
Select the file by clicking on it one timeClick the 'delete' button on the keyboardYou will be asked if you really want to delete the fileClick 'Yes'If you do not want to have to do that extra click to confirm the delete operation hold the Shift key down when you press the Delete key.The procedure above will lable the area(s) occupied by the file as "Free" which means that another file could use part or all of the portions of the disk that held the 'deleted' file's information. Deleting in this way WILL NOT remove the information from your hard disk. If someone with enough knowledge, the right software and time looks hard enough they will be able to reconstruct som or all of the 'deleted' files.To really remove files and make them inaccessible you need special software. It is probably easier to buy a new hard drive and destroy the old one.
If a video is downloaded from limewire and deleted is it still on your computer?
Yes. Anything you put on your computer isn't really gone if you delete it- it just doesn't appear in the system registry (this fact often helps the FBI build cases against criminals like pedophiles). The only way to really protect yourself is to format the hard drive, get a good registry cleaning program, or one that 'shreds' (deliberately corrupts) deleted files so that they're impossible to identify. If I were you, I would also make sure that you disable uploading from your machine- that limits the amount of damage you can be held liable for because you never shared with anyone else.
When you work on files on a computer where are they held?
RAM
Is a hard disc drive an output device?
no. it is a backing storage device. because it gives the user fast access to the information held on them.
Can you photocopy a driving license to be held on employee files?
Yes
What does it mean to parition something?
To partition something means to divide it into several parts that are held separate from each other. This is true whether the partition is of land, as in Palestine/Israel, or of a hard drive, such at the main drive of a computer.
Can computers can only retain data temporarily?
Data held on the hard drive, is considered to be permanent. It will still be there, after the power has been removed for many years. Random Access Memory (RAM) is the working memory, held on microchips and needs power to keep the data. It will be immediately lost when the computer is switched off. This usually of little consequence as important data is always held on the hard drive. The RAM is only used for temporary data whilst working.
What are the differences between RAM ROM and Hard-drives?
ROM or read only memory is used for the system BIOS and build-in operations. The ROM can only be read and not written to. A hard disk, on the other hand, is a magnetic medium which is designed for continuous reading and writing.
What is the purpose of a DVD hard drive?
To hold the operating system files, operating system, save data, all the information in your computer will be saved on the hard drive. The hard drive keeps all the data even when there is no power. It will stay forever until changed or removed by the computer. Hard drives use a spinning magnetic disc and magnetically recorded and read from, using a swinging arm with a minute read/write head on it. Called a hard drive to distinguish it from early magnetic discs, which were made of plastic film and called 'Floppy discs', because they were floppy (but held inside a rigid platic cover.) Thats why you need to destroy your hard disk drive before disposal of your computer. Make sure the disposal is in a special place for electric stuff. The data will survive, even when the hard drive is removed. It can be plugged into another computer and read.
