Hard Disk Drives
In a personal computer, a hard disk drive controls the positioning, reading, and writing of the hard disk, where data is stored.

When setting up a computer what is the first thing you should install?
Software Word 2007 ,but intranet will already be installed if you get the type of comp. that offers that software.
Is USB 2.0 or Firewire faster?
The maximum speed of USB2 at 480M/Sec is a little quicker than Firewire 400 (IEEE.1394a) which runs at 400 M/Sec (hence the "400" bit of the name). In tests, however, FireWire 400 delivers a higher sustained transfer speed. Benchmarks suggest that hard drives connected with FireWire will copy information considerably faster than they would using USB 2.0. To achieve higher performance, FireWire requires additional circuitry in supported devices. This often makes FireWire more expensive than USB 2.0. Firewire 800 (IEEE.1394b) as the names suggests, has a peak speed of almost 800 M/Sec. Used primarily by PC musicians for recording and transferring multichannel audio at high sample rates and for digital video cameras and decks
Why is a hard disk inside the system unit sometimes called a fixed disk?
Floppy drives and CD/DVD roms are examples of removable disks because the storage medium is removed from the drive. A hard drive has a set of magnetic platters that you do not remove, making it a fixed disk.
How can a computer ensure the safety of data stored in a computer system?
The biggest thing is backups. Using a RAID 1 configuration helps in cases of hardware failure, since if one hard drive fails, you have the other one and can rebuild the set from it with very little downtime. However, unlike backups, RAID 1 (another other RAID configurations) does not protect against data corruption from viruses and deliberate sabotage. Nor does RAID 1 help you if the computer is physically stolen. You can replace the computer, but you cannot replace what is on it as easily a lot of times.
There also needs to be malware solutions. Antivirus utilities are one such help. Safe computing policies and proper Internet settings also help.
Another point is security practices and solutions. Not only do you need protection from data corruption, but also against how the data is used. You don't need your emails getting leaked to your competitors or some group who wants to put you out of business. Nor do you want your computers and network being misused for criminal activities. So you must use the right security and firewall settings, and also secure your networks and relays from being used by those who have no business using them. If espionage is expected, then you have to screen and monitor your employees, and not provide any means for spying (for example, disable external media like USB drives). Sometimes setting the computer to only read outside media is good enough, then nobody can copy it out. But then you run into the possibility of malicious software getting installed, perhaps snooping software, enabling a bad employee to access the company's data from elsewhere.
What is the difference between drive c and d on the computer hardrive?
c: is that partition of ur harddisk from where ur system boots and d drive is any other partition.
What are three ways to improve hard disk performance?
Three ways to improve the hard disk performance of your computer include defragmenting, removing duplicate files and by compressing or encrypting folders. These methods help to create hard disk space, thus making your computer run faster.
Where can you find informantion about your hard disk recovery?
Typically any software application you use for hard disk recovery will provide a comprehensive report when the recovery has been completed. If you are having any issues with a particular application, contact their customer support for detailed information on how to obtain and read the generated report.
You need to insert a hard disk each time you use a computer?
I assume you mean floppy disk. Hard disks (hard-drives) are designed to be connected and not usually removable without opening the case.
if you are referring to a Zip drives' hard-disk then no - not usually - unless it is required by an application or as a security measure.
When installing a hard drive and a CD-ROM drive on the same IDE channel?
You can install the hard drive and a cd/cvd disc drive on the same IDE channel,
just set jumpers to HDD=Master & optical drive to slave.or if your system supports cable select, set both jumpers to this setting.This solution is usefull if one of your IDE channels has "blown"
What is billion bytes on a hard disk?
On a flash drive, one billion bytes is called a(n) _____________.
When you buy a computer it usually has some software preinstalled on its hard disk.?
There are some software pre-installed in the chipsets of the hard disk drive (HDD) but nothing on the disk itself. Those pre-installed software instructs the HDD how to write/erase information on the magnetized disks.
Write a short note on magnetic disk?
Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic. It was developed in Germany, based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores computer data on magnetic tape is a tape drive.
a microfilm is an example of bothboth a hard copy and soft copy device. This is due to the fact that it is temporary output and can be read read visually also as it is a printed copy of computer output
Why is a hard disk so important?
Well the hard drive stores all your personal data and system data, without a hard drive to boot your operating system from all your left with is a glorified side table.

Where a computer store information?
Any data that needs to be stored for temporary or permanent use, is saved onto the platters of the computer's internal hard drive, or on an external hard drive/flash drive.
What is magnetic disk storage capacity?
Tape remains a viable alternative to disk in some situations due to its lower cost per bit. This is a large advantage when dealing with large amounts of data. Though the areal density of tape is lower than for disk drives, the available surface area on a tape is far greater. The highest capacity tape media are generally on the same order as the largest available disk drives (about 5 TB in 2011). Tape has historically offered enough advantage in cost over disk storage to make it a viable product, particularly for backup, where media removability is necessary.
Yes, but they are slightly larger (for now) than the "thumb drive" versions.
As of 2011, the price for large-scale flash drives has continued to come down. Some 256Gb drives fell to less than $700 USD, and modifications can be made to existing drives to allow 1 terabyte of data storage. The price for an actual 1 Tb drive (solid-state drive) was still in the $3000 USD range in early 2011.
What is an internal peripheral?
Some examples of internal peripheral devices are cd/dvd drives, internal modems, and e-card readers.
What does a internal hard drive do?
A hard disk drive (often shortened as hard disk, hard drive, or HDD) is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid (i.e. hard) platters with magnetic surfaces. ...

How many primary partitions does MBR support?
A single MBR-Style disk can contain a maximum of four primary partitions.
How often should scan disk defragmenter be used?
You only really need to defragment when the performance of the computer is noticeably affected. Depending on your usage of the computer, this can be anywhere from every couple of days to a few weeks. Doing so more frequently does not hurt however, and it may make future defragmention sessions less time-consuming.
