Hard Disk Drives

Desktops have expansion ports (PCI ports) where you can add new cards such as sound cards or network cards. Laptops often only have a single bay for this purpose.

Desktops tend to have better performance because they don't have to run on batteries. That means the processors and video card can be designed to use more power and can take up more space. Hard drives are similarly faster and have higher capacity (in general).

In general, its is much cheaper to build a high performance desktop PC than it is to build a high performance laptop due to the power, size, and heat constraints that a laptop has.

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.

As a rule of thumb, I'd deduct at least 50% depreciation per year. It's actual worth is dependent upon how old it is, what condition it is in, and how many hours it has actually been in use. Hard-drive manufacturers typically provide an MTTF (mean time to failure) expressed in hours. This is the average number of hours of continual use you can expect to get from a hard-drive before it is expected to fail. It is not an exact science, it is merely a guide figure, however, the closer a drive gets to its MTTF the less worth it has. Personally, I treat all second-hand drives with suspicion as it's hard to tell its true condition just by looking at it. You need to install it, inspect the SMART (self-monitoring and reporting tool) information, possibly reconfigure its geometry and soak test it for a week or two before deciding if its really fit for purpose. Even then, there's no guarantee it won't fail the moment you pay for it. At least if its an out-of-box failure you can get it replaced. You just don't get that sort of guarantee with a second-hand drive.

just one optic cable can carry a lot information to computers

It depends on the serial bit rate versus the parallel strobe cycle time but, in general, a parallel interface is faster than a serial interface. However, modern USB, Firewire, and SATA interfaces are very fast, and might be considered faster.

The BIOS of virtually all Pentium III computers is limited to 128 GiBs (a 137 GB hard drive). While you can put any size hard drive you like in the system, Windows will only be able to see 128 GiB of it. Linux should be able to address all of it, as it does not use the BIOS to access the hard drive.

You can bypass this limitation by installing a new IDE / PATA controller in an available PCI slot. Although this will increase the time it takes to boot the system slightly, it will allow you to use all available hard drive space in Windows XP (SP1 and later) and Windows 2000 (SP4).

Druids were members of the priestly and learned classes of Western Europe, Britain and Ireland. They combined the duties of priest, scholar and teacher.

The "civilization" also had warriors, who, at times of war, would use body paints. I do not know why they did this though but if you do please feel free to delete this.

If a disk is fragmented, this means that the files in your computer are spread out all over the disk taking up too much space. This can be corrected by defragmentation which consolidate all the data.

There is difference between SATA and PATA HDD but no difference between the formatting..

You can purchase an online hard disk enclosure from the shopping website known as newegg. Alternatively you may find a better price on the amazon shopping website or from the ebay bidding website

That depends on how many drives or virtual drives you have on your computer. Mainly the C: drive has Windows on it, if you only have a C: drive all your information and programs go here, but if you have multiple drives C: drive should be mainly for your Windows operating system.

That is a job for the trusty printer.

The hard drive disk (HDD) is connected to the motherboard as with all the other components in the computer. If the computer needs to save data onto the HDD than the user input will be processed through the motherboard via the CPU (processor) and transferred into the HDD. If data is needed from the HDD once again the request will be sent through the MB via the CPU to the HDD where it will then be put back through the MB to go into the network via the network cards or USB via USB Interfaces or virtually anywhere else it is required to go.

These days (2012) you will not find many floppy disks (although just a couple of years ago we had to order special floppy drives for a server because some software would only be installed if it booted from Drive: A a floppy).

There were 8 inch and 5 inch and 31/2 inch floppy disks which were common.

The latest (diskettes) were the smallest and were protected by a hard plastic casing. Inside a thin Mylar disk coated with a magnetic surface stored the 1.44 Mb that was the capacity of most diskettes.

Hard disks have one or more aluminium or glass disks coated with magnetic surfaces. These hold much more information and now (2012) there are units that can store 3Tb or more.

HDD is an abbreviation for Hard Disk Drive.

That depends on the drive. There are many different sized drives, so you will need to check each one. most modern drives are at least 64GB, and usually more like 512GB (called 500GB)--there should be a sticker on the casing which will tell you. You could also check through your system. To do this, you will need to know how many partitions your drive has. Usually there is only one, but if you have a backup partition or multiple operation systems, you will have more. Open Windows Explorer to "My Computer." Right-click on your C: drive and select properties. Under the General tab, you should see a pie graph showing your drives space. Just above that you should see an entry for "capacity" and read the number of GB it lists. If you only have one partition, then that is just under the size of your drive. If you have multiple partitions, then do this for each partition, and add then up. The drive will always be a little larger than the number you come up with, since some space is used in formatting, and some may not have been usable for partitioning for whatever reason.

To read, there are very small electric coils that sense the magnetic polarization; these coils are mounted on arms which pivot and move across and very close to the surface of the disk.

(see the image link under Sources... below)

These coils read the polarization which represents the 1's and 0's of the binary information stored on the magnetic disk.

The write mechanisms make use of the electricity flowing through a coil in the write head that produces a magnetic field. Electrical pulses are sent to the write head, with different patterns of positive and negative currents. The current in the coil of the write head induces a magnetic field across the gap between the head and the magnetic disk platter, which in turn magnetizes a small area on the recording medium.

The Read/Write head assembly works to read and write using basically the same technology, early units used the same hardware for both, modern units can have slightly different configurations of the microscopic gaps between coils and magnets etc. for optimum performance.

The partition of British India took place on August 15, 1947. This event led to the creation of two independent dominions, India and Pakistan, as a result of the end of British colonial rule. The partition was marked by significant communal violence and mass migrations, as millions of people were displaced along religious lines.

When you are in a country that drives on the right, then generally you should drive in the right lane; the left lane is for passing.

When you are in a country that drives on the left, then generally you should drive in the left lane; the right hand lane is for passing only.

When you initially receive your new PC, it is important to keep your recovery disks in a safe place. Current practice though does not guarantee that you will receive any back up disks at all. In the case that you do not receive them, the cheapest solution for Windows Recovery Disks is to make them when prompted while setting up your computer. In the event that you do need them down the road, the best way to find recovery disks is to contact the manufacturer of your PC so that they may send you the recovery disks that you need.
