Data Storage Devices

The first sector of a floppy disk or logical drive in a partition; it contains information about the disk or logical drive. On a hard drive, if the boot sector is the active partition, then it is used to boot the OS (Operating System; i.g Windows Vista is an OS). Boot sector is also called the boot record.

You tell me stupid.... Just joking. You can remove the hard disk if the machine holding it breaks.

Example: I am using my hard drive to save stuff and then it breaks. what do i do? remove the hard disk (with professional assistance of course).

Previous Answer: two types of magnetic disc are magnetic tapes and compact disc

Actually neither of the above are correct. Magnetic "Tape" is exactly that it is a tape, a long slender ribbon which comes in two formats that I know of which are "cartridge" and "reel to reel". Compact Disk is an optical media.

There are several types or formats of Magnetic Disk, sizes and capacities vary.

Fixed Disk:

Hard Disk otherwise referred to as HDD. It can have one or more disc platters made of aluminum alloy or glass with a thin magnetic layer bond. These magnetic disks or platters are sealed within the enclosure. Size 1.8", 2.5", 3.5", 5.25", 8", 12"

Removable Media:

Floppy Disk, removable disks that can be in a hard or soft shell enclosure. The disk itself is a plastic with a magnetic layer bond and is "floppy" one or both sides can be used depending on the disk. sizes range from 3.5", 5.25" to 8"

Floptical, the likes of a floppy however one side is magnetic for storage, the other is optical for head positioning. Size, 3.5"

Cartridge Disk, similar to the floppy or floptical but the cartridge actually contains a platter the likes of that within an HDD. Size 5.25", 8" that I know of.

a sd card can store in megabite or gigabite upto 2 gigabite.

Neither a DVD nor a CD would be affected by magnetic fields, because the information is digitally encoded using optical media.

External drive bays

The newest commonly used storage device would be the usb flashdrives because the have more space and dont break as easily( that last part could be argued with)

There are many storage devices that are used in everyday computing. If you mean storage devices as for what you can use to store data and save then I believe the following are very common:

* Hard drive * DVD * CD * USB Thumb Drive * Compact Flash Drive (the small flash drives you put in camera's) * Network Storage Server (If you save files online this is what is used) RAM is another storage device but it is only used by the operating system on your computer. So you really have no ability to save information on them.

No. A disk drive can use one of several methods of storing data, including magnetic, Flash, and optical.

Optical disk storage offers several advantages over magnetic disk storage, including greater durability and resistance to environmental factors such as dust and magnetic fields. Additionally, optical disks typically have a longer shelf life, making them suitable for archival purposes. They also tend to consume less power during operation and are often lighter and more portable than magnetic disks. However, optical disks generally have slower read/write speeds compared to magnetic disks.

I would like to tell you that ROM stores the programs that are executed when the computer is switched on. It has a program thatactvates RAM and RAM starts its work. Its work is to take small and important information about the software that is running or the operating system to be loaded. Hope you understanded what you wanted.

Let's see:

Harddrive

Solid State Memory (RAM)

Optical (DVD / CD / Etc)

Memory Cards? (SD Memory / CF Memory / Etc)

Technically the last would be the same as RAM, but it isn't used the same. RAM is used in most computers as temporary memory. This memory only retains information while power is provided to it. Once the power is removed then it loses everything. With a memory card type of memory such as NAND type of memory, information stored in the memory card is retained even when the power is removed (USB memory sticks / SD memory / etc).

The drive interface that uses an 80-conductor ribbon cable is IDE. IDE stands for Integrated Drive Electronics, an interface commonly used to connect hard disks and optical drives to computers.

optical disc encodes binary data (bits) in the form of pits (binary value of 0 or off, due to lack of reflection when read) and lands (binary value of 1 or on, due to a reflection when read) on a special material (often Aluminium) on one of its flat surfaces. The encoding material sits atop a thicker substrate which makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data is stored on the disc with a laser or stamping machine, and can be accessed when the data path is illuminated with a laser diode in an optical disc drive.

Because alternative media won't boot with alternative operating systems.

Read only memory (ROM)

Tony Jennings did he was the first person

NAICS 334112 applies to Computer Storage Device Manufacturing.

You only need to buy one copy of any software you wish to use. Software is loaded onto the network drive, and is accessed by users 'logging-on' to individual terminals. Putting the same software on (maybe) dozens of computers would be much more expensive.

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.

dick lick the disk till it splashes

They are considered Flash storage or elecctronically errasable got this from my thechnology in action textbook in college
