Data Storage Devices

RAM

To removed write protected mode from your usb pen drive you must first reboot your device when your device comes back on press f8 frantically. This will prompt your device to advance settings, let your files load and than rename your pen drive and hit enter after that hit enter again when asked about the formatting of your new drive, press yes when the prompt appears, allow your system to reboot, this may take some time but after rebooting your pen drive will be removed.

There really isn't a standard size. It's all a matter of opinion and depends on what you will be using the computer for. Generally, they range between 100 GB and 500 GB, but can exceed into the 10 TB range (TB stands for terabyte).

Yes, a DVD burner or a DVD burning software is needed to create a DVD. for example, you have a movie or you download some video files( YouTube video and so on), and you want to watch them on DVD player, so you need to convert and burn them to DVD.

For you to write to a disk, the write-protect notch must be closed.

Solid state backing storage, or backup storage, is a way of storing information that has no moving parts. The small, plug-in modules often called USB drives or thumb drives are a common example of this type of storage.

I'm not an engineer, but while lasers are used to read both CD's and DVD's, the required laser is different. I suppose it is due to the frequency that the laser is reading. Anyway, DVD's are about 3 times tighter packed than CD's, so the CD's laser can't focus in on the data. This is why if you tried to store a movie on CD (using the CD-i format, for example), you would end up with 3 or 4 CD's compared to one DVD.

Typically random access memory (RAM) is the primary storage device and the slower rotating magnetic media (disc drive) is the secondary storage device. Other devices like USB thumb drives and other removable media are considered tertiary (3rd level) storage devices

RAM - standing for Random Access Memory. The contents of RAM are lost when the computer is turned off.

Memory is a loose term when it comes to computers. Memory can mean one of two things that are both primary and absolutely necessary to run a computer. One is RAM, which is the smaller memory that helps with computer performance. Without it, the computer will not start up at all because the RAM is used for essential backround tasks. The other memory is HDD memory (hard drives). This memory is used to store information that does not need to be accessed instantaneously. HDD memory is used to store the operating system of a computer, as well as other information such as programs and documents. There is no "primary" memory, in a computer, as it can mean two different things that are both invaluable.

One can store their computer data online via cloud storage services. There are a number of cloud companies one can use including 'Amazon Cloud Drive', 'Apple iCloud', 'Google Drive' and 'Microsoft SkyDrive'.

1 bit = a 1 or 0 (b)

4 bits = 1 nybble (?)

8 bits = 1 byte (B)

1024 bytes = 1 Kilobyte (KB)

1024 Kilobytes = 1 Megabyte (MB)

1024 Megabytes = 1 Gigabyte (GB)

1024 Gigabytes = 1 Terabyte (TB)

Yes. In fact, it can only access data sequentially. Because tape is very inexpensive and will hold data fairly well for a long time, it's still in use even today, but memory access in sequence, not random, is much much slower. It's like having one-hundred 3x5 cards that you have information written on. Sequential memory is like having the hundred cards all stacked together and you can only access them by flipping through one at a time in order until you get to the card you want. Random memory is like having all the cards spread out on a big table so you can just go straight to the ones you want.

Several methods to remove blank partition

1, right-click Delete, but accuracy is not high, after using the partition may not be very convenient

2, use the partition Wizard Professional software tools, like minitool Partition Wizard, simple operation. Has little effect on other partitions

True

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.

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.

MicroSD are normal MicroSD cards, which are equal or less than 2GB storage.

MicroSDHC are High Capacity MicroSD cards, which are equal or bigger than 2GB and less or equal than 32GB.

MicroSDXC are Extreme Capacity MicroSD cards, which are equal or bigger than 64GB.

At the moment there are none MicroSDXC cards. It's interesting to read http://www.teamcyclops.com/forum/showthread.php?t=11110 and http://phandroid.com/2009/01/08/coming-soon-2tb-memory-cards/ about MicroSDXC cards (which could have a storage of 2TB). That's awesome.

Some devices have a limitations. E.g. it's impossible to use a 8 GB microSDHC card on Sony Ericsson K750i, but it's possible to use a 2GB microSD card.

Walmart is the best place to go for low prices and I know that they have tons of memory cards there. The staff their will be happy to help you find the correct memory card you need for your benefit.

file allocation table (fat)

no, it is an input device, but you cannot store any date in a keyboard itslef

Put it in the microwave.... commonly used by people in the military to destroy electronic documents... It won't hurt your microwave either,

They are just made (mostly) of thin plastic, so you can break them fairly easily if that is what you want to do. If you are trying to avoid destroying them, I recommend that you keep them dry. Water can damage them. Don't store them in direct sunlight, either.
