Hard Disk Drives

Because it lets you know how much space is left, and it let's your computer store information more efficiently.

Defragmenting regularly also helps prevent your computer's performance from degrading. Over time, as files are added, modified and deleted from your disk, individual files can become fragmented - rather than being stored in one contiguous location on the disk, they're split into sections and stored in different parts of the disk. This adversely affects performance, because the entire file can no longer be retrieved from a single location on disk. Defragmenting regularly helps to prevent this and keep your computer running smoothly.

To provide PC devices either 12 V AC or 5 V AC, or even ( 12 - 5 = ) 7 V AC. I don't really know whether any PC device uses 7 V AC...

Everything is repairable... If you can get the case open its just a regular hard drive inside you can replace it. If its a cheap brand you may be better off replacing it.

Yes, but the system may not function properly if you hope to boot from that disk. The swapped disk can be a second or third disk on a system, but if you want it to boot from that disk you'll probably need to re-load the OS.

Data can be stored on a floppy disk, since that is what they are designed for. As for whether it can be "received" on one, that is a pretty vague question, as it doesn't address HOW the data is received.

BIOS is only to detect the drivers. You will see each driver in the BIOS setting. If you have 2 hard drives, you will see 2 drives in BIOS,but if BIOS Only recognize 1,that means 1 drive have a problem. Happen to me many times. Then when finally you are in windows(desktop)then you click on my computer and click on every hard drive then you will see the size of every drive. But not the 1 that was not recognized,because it will not be present.

You can purchase form factors (minus power-supply) for as low as $32.00 US

Basically, these are the memory units used to represent the memory of the computing devices.

1. Bit

2. Byte (Contains 8 bits)

3. Kilo-byte (Contains 1024 bytes)

4. Mega-Byte (Contains 1024 kilo-bytes)

5. Giga-Byte (Contains 1024 Mega-bytes)

6. Tera-Byte (Contains 1024 Giga-bytes)

and so on....

Yes, a hard drive is more properly called a hard disk drive. They are not the same thing, but a hard disk drive is a type of disk drive, just like a floppy disk drive is another type, and just like a soft armor and hard armor are both types of armor. You can pretty much use "disk drive" and "drive" interchangeably in computer contexts.

The most confusing thing about hard drives is that they contain fixed (non-removable) disks. You don't SEE the disk(s), because they're locked inside, and so you could easily wonder if it's actually a disk drive.

Some people use hard drive and hard disk interchangeably, probably because they're not really sure what the difference is. Most of the time it really doesn't much matter much, but it's important to understand that there are other kinds of disk drives: floppy disk drives, tape drives, optical drives (CDs, Blu-ray discs, DVDs, etc.), magneto-optical disk drives (M-O drives) too. All of these tend to have removeable disks, which you can change. The drive stays, but the disks in it can be swapped around at will.

They're called hard disk drives because the type of physical disk that spins around inside (the disks their motors DRIVE around) are hard, like an old style vinyl record (metal or ceramic coated with a magnetic material), rather than soft like a floppy disk (plastic with a similar material).

Note that flash drives (aka USB drives, aka Pen Drives, etc., more properly called solid state drives) are another of the few drive types that have non-removable disks. They're subject to the same confusion that hard drives are subject to. In other words, a USB pen drive also has a USB disk within it. Generally they have four main parts if you open them up: the drive chip, the memory chip (disk), the USB connector itself, and the circuit board that links them all together. Might help to look inside an old one some time, just to be extra clear about how separate these things really are.

A computer's hard disk or hard drive stores information such has the operating system, programs, and files. It stores the information as small magnetic fields on the hard disc.
A hard disk drive is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid (i.e. hard) platters with magnetic surfaces.

True

The best way to repair a scratched disc is to take it into a specialist. There are also some mixtures that you can whipe on the disk to try and fix it. Most of the mixtures won't completely fix the scratch, just try to cover it.

not sure

IBM 350, 5 million characters (6-bit).

Yes, the name of the software is Western Digital Data Lifeguard or DLG.

There aren't really different types of CPU, but there are some major differences between CPUS. Like Bus Sizes - we have 32 & 64 bits. Some support SSE, SSE2 and SSE3. But there are different processor architectures which you are probably talking about. There are SPARC, IA64, X86, X64, IBM Cell and more.

I believe the 3 types of CPUs being requested are:

CISC: Complex Instruction Set Computers

RISC: Reduced instruction Set Computers

MISC: Minimal Instruction Set Computers

The IDE Driver software that is needed to Format, write, read, fragment and maintain the FAT for that.

Ther can only be one Extended Partition per hard drive

what are the strengths of a floppy disk

Information is stored as ons and offs, represented as 1 for on, 0 for off

This is commonly known as binary (meaning two numbers).

Binary can form numbers, by combining 8 bits (smallest unit of memory, either 1 or 0) into a byte.

it works like this:

Each bit is given a number double the previous, and when that number is "on," it is added to the total.

so in a byte, we get

1 2 4 8 16 32 64 128

And we can represent any number up to 255 by switching various numbers on and off

Note; for numbers beyond 255, the doubling is continued into 16 or 24 bits.

for example, to represent 13, we need

1, 4, and 8 (1+4+8=13)

1 2 4 8 16 32 64 128

1 0 1 1 0 0 0 0

To store text, each character is given a number. These character numbers are called ASCII (american standard code for information interchange)

For example, letter A has the number 35, so would be represented as 11000100

Hope this helps

DISH NETWORK AND DIRECTV are working on that option for their DVRs. DISH NETWORK's option allows the use of a standard external USB drive, but it formats in a propietary format so it cannot be moved from one DVR to another. Thank you RIAA and MPAA for that wonderful option!

DISH NETWORK currently has a series of DISHPlayers that video can be downloaded through the USB port on the DVR to the DISHPlayer personal video player
