Data Storage Devices

For what storage medium are phase change alloys used?

If broken in half no if scratched it depends on how bad the scratch is

Windows 98 should automaticly assign it a drive letter. You can try running new hardware wizard in the control panel if the wizard does not find it you might also check the jumper on the drive itself and make sure it is not conflicting with any other drive (set the same as the hard drive)

Withdraw at least 50 yards from the scene and tell the Incident Commander immediately.

It's a storage "medium" rather than a "device."

A device is a machine or component that attaches to a computer.

A medium (singular form of "media") is any technology that can be used to keep and retrieve data. It can include devices (like hard drives) or material (like magentic tape).

None. A megabyte is a unit of binary data and has no direct relationship to physical hardware.

I am not sure you can, but you can make the files read only...

Computer storage does not have any mass.

you can get computer imaging software that will do that for you, or your computer has to be set up to run RAID. this requires two drives and a bunch of technial knowhow. But it is a pain in the butt to convert raid data back if your primary drive crashes. It will however do what you want and mirror your primary drive

Basically your PC will be faster, 2 things affect the speeds of computers, CPU/Processor is raw power, RAM enables more things to be done at once, however because your computer is doing hundreds of things (in the background) even if your only writing a word doc, being able to do more things also increases the speed. 6400 runs at a faster MHz therefore the ram is faster than the 5300, however you shouldn't mix and match, RAM should always be in matched pairs if possible, your PC will probably run faster with 2 5300's rather then a 5400 and a 6400 (even though this would seem better).

SACD is not dead. It is however a niche format. There are plenty of new releases - majority of which is classical music. High definition format such as SACD really only benefits quality recordings of music with high dynamic range such as classical and jazz. Likewise, there are SACD players that are still maufactured - most notably the Sony's PlayStation 3 (some models only) and also various models from Marantz and Denon as well as cheaper Oppo. DVD-A does appear to be dead to my knowledge.

Some tablets use SD cards for extending storage of apps and data, but this will affect the performance, as reading and writing to an SD card is slower than RAM. Tablets do not have expandable flash memory, but many have expandable SDRAM.

Both are magnetic media used to store information.

It is the memory capacity of the storage unit.

Hi,

All hard drives can be removed. Normally Hard disks are connected inside the computer to the computers main circuit board called the Mother board. They connect to the IDE connection point using IDE(Integrated Device Electronics) cable. Since the box must be opened to take these out they are considered non removable. Removable Hard disks connect to the computers USB (Universal Serial Bus) point outside the box making them easy to put in and remove. The device themselves are the same. They are like old record players. They are a series of metal disks called platters stacked one on top of the other that take electric charge to store data. Not to be confused with Memory sticks that also act like Hard disks. These are really just Memory modules with batteries to prevent them losing information when you take them out of the computer. Memory modules (Ram) are your computers short term memory (Thinking power). When programs run data is not stored but short term memory is enabling all the functions that are happening in real time like calculations and what you see on the screen are stored. Hence when you turn off or get a power cut these short term things are no longer as the ones in the computer dont use batteries to make the information more permanent. Hence why Memory sticks are not proper hard disks. Because a loss of power to the printed circuits and chips means Information loss. But with a Hard disk you can send the disk away to a specialist to take the platters apart and read the physical changes in the platters to be read. Information recovery. Hope this was'nt too long winded & i hope it was helpful Michael

Solid State Disks have no moving parts (e.g. platters, heads) that could be damaged if the computer was dropped while running.

No, tape drives use magnetic means for storing and reading data. Any kind of Compact media, (CDs, DVDs, Blu Ray, etc.) on the other hand, use lasers to read and write data. (Verify that part, someone.)

== == Although they were available on large systems used by business, government and other institutions, hard drives in home computers were unheard of until at least the mid 1980's. Even then, They usually cost more than the computer itself, and were physically large, coming in external enclosures the size of a shoebox, and very heavy (noisy too). Yet the storage was only around 10 megabytes (give or take). It didn't even seem like much storage back then, since they could only hold the contents of a few floppy disks, at a very high price. The main advantage was the speed of accessing your files, but even that was much, much slower than today's disks. It wasn't until the early 1990's that internal hard drives became a standard feature on PC's. (and only 30-40 mb at first!)

My first computer was in 1984 and was a Tandy computer made by Radio Shack. It didnt even have a hard drive. Everything was done with floppy disk. The big thin kind. I forget the size of it now. My first computer with memory was an IBM in 1990 and it had a whopping 500 mb of memory. Good luck.
