What does surface storage mean?
Its basically the part of precipitation retained temporarily at the ground surface as interception or depression storage so that it doesn't appear as infiltration or surface runoff
Will 140MB fit on a 1GB drive?
Because 140M is megabytes which is much less that 1G (1 gigabyte) = 1024M, it will fit about 7 times. Anyway usually the 1G drive is not usually guaranteed so it's only approximate value. FYI: M = MB = megabyte (1 * 2^20 bytes) and G = GB = gigabyte (1 * 2^30 bytes)
An evaporating disk is a disk that is used specifically for evaporation. It is made out of ceramic. It works by heating a liquid over a flame, the liquid evaporates and leaves a solid residue.
What is the use of ZBR in the context of disks?
Zone Bit Recording (ZBR) is used by disk drives to store more sectors per track on outer tracks than on inner tracks. It is also called Zone Constant Angular Velocity (Zone CAV or Z-CAV orZCAV).
On a disk consisting of roughly concentric tracks - whether realized as separate circular tracks or as a single spiral track - the physical track length (circumference) is increased as it gets farther from the center hub.
Physical layout of sectors in a zone-bit disc: As distance from the center increases, the number of sectors in a given angle increases from one (red) to two (green) to four (grey).
The inner tracks are packed as densely as the particular drive's technology allows, but with a CAV drive the data on the outer tracks are less densely packed. Using ZBR the drive divides all the tracks into a number of zones, and the inner track of each zone is packed as densely as it can, with the other tracks in that same zone recorded with the same read/write rate. This permits the drive to have more bits stored in each track outside of the innermost zone than drives not using this technique. Storing more bits per track equates to achieving a higher total data capacity on the same disk area.[1]
On a hard disk using ZBR, the data on the tracks in the outer most zone will have the highest data transfer rate. Since both hard disks and floppy disks typically number their tracks beginning at the outer edge and continuing inward, and since operating systems typically fill the lowest-numbered tracks first, this is where the operating system typically stores its own files during its initial installation onto an empty drive. Testing disk drives when they are new or empty after defragmenting them with some benchmarking applications will often show their highest performance. After some time, when more data is stored in the inner tracks, the average data transfer rate will drop, because the transfer rate in the inner zones is slower; often making people think their disk drive is slowing down over time.[1] Some other ZBR drives, such as the 800 kilobyte 3.5" floppy drives in the Apple IIGS and older Macintosh computers, don't change the data rate but rather spin the medium faster when reading or writing outer tracks, thus approximating constant linear velocity drives.
What is dynamic disk and its type?
The Dynamic Disk is a physical disk that manages its volumes by using LDM database. What is the LDM database? LDM is an acronym of Logical Disk Manager, and it is a hidden database which size is 1MB at the end of the Dynamic Disk. The 1MB space records all the information of the volumes on a single disk, and also holds some related information on each dynamic disk. Such as Drive Letter, Volume Label, the begin sector of Volume, Volume size, the file system of Volume, and the current dynamic disk is which one and so on.

What is the lifespan of an HDD compared to an SSD?
i have tried researching this on google and really came up with nothing useful. i believe this is mainly due to that HD Drives are so much more popular/cheaper, and that SSD's have not been tested by a large number of people. (the general public)
i have read they can last 'a good 20 years' but i would not buy into that even in the slightest. That aside, i read 5 years, so that might be it as well.
That would mean the lifespans of both are about the same, it is just that an SSD is much more expensive, but for a HUGE performance boost in both Reading and Writing Data.
HDD Lifespan:
-At least 3 years
-At most 5 years
SSD Lifespan:
-At least 3 years (guessing)
-At most 5 years (expected, but unconfirmed)
And, then here is another persons answer below.
"No moving parts - no heat so less wear - " green " as low energy requirement. - to drop in price as demand increases"
What is the storage requirement for the drug Neupogen?
Keep stored in the refrigerator at 2 degreesC to 8 degrees C (36 degrees F to 46 degrees F).
This is one way that Flash Memory storage devices can be built.
- ROM, all such devices are a type of Programmable Read Only Memory (PROM), memory that although it can be written to takes orders of magnitude longer to complete a write cycle than it takes to complete a read cycle.
- 16GB, size in this case about 16 billion bytes.
- NAND, the type of logic function used internally by the device, This can be either NAND or NOR but NAND seems to have become most common. NAND means NOT AND while NOR means NOT OR, just as in the corresponding logic gate types.
- Flash, is a specific type of PROM architecture that reduces the impact of the slow write cycle by writing large "sectors" of many bytes simultaneously instead of one byte at a time as in other PROM architectures. Flash also provides many "sector" buffers that the computer may be writing data into while the chip is busy programming one "sector" buffer into the memory. Flash is ideal to provide a solid state replacement for harddisks.
What is the rate for storage at data center?
The rate for storage at data centre depends on how much data you want stored. You can store a few gigabytes for as little as a few dollars a month or a ton of gigabytes for hundreds of dollars.
What are the advantages and disadvantages of using different types of storage mediums?
Advantages of different types of storage mediums are having multiple backups in multiple locations that can be accessed from a variety of systems. Disadvantages are that they can be easily lost or stolen and may be more easily corruptible.
Can a solid state drive overheat?
A solid state drive is nearly impossible to overheat unless it is being deliberately or accidentally heated through a source other than the computer itself. The chips and interface themselves produce somewhat less heat than a traditional hard drive and are therefore less likely to interfere with any hardware that !is! sensitive to heat.
Is USB device replacing floppies as a means of transporting data from one computer to another?
One would think so. The limitation of a 3.5 inch floppy is 1.44 MB of data. USB memory sticks most commonly hold at least 1.0 GB and upwards of data. Besides the obvious smaller size, also the convenience of the USB stick makes it easier to use. The majority of PC's being manufactured these days does not include a floppy drive.
What would be the problem if you use older cd-rOM drive to play cd-r pr cd-rw?
there really wouldn't be a problem, the only problem you might encounter is the fact that an old CD-ROM might not play CD-r's and CD-rw's depending on how old the drive is.
Storage hardware store the data.Like Hard disk,Pen Drive,CD/DVDs these are storage devices.
How can you put pictures off the computer into your sd card?
First, the memory card should be inserted into the computer, and a window opened for the card. The window of the drive holding pictures on the computer should also be opened. Then the pictures can be selected and copied from the computer window and pasted to the card window.
What is the function of external device?
External devices can carry out all sorts of different functions.
What is Printer terminology in Citrix?
1.Local Printing.
2.Network Printing
3.Client Printing
Client Printer: The printer connected to the Worksation & the drivers are installed on the citrix server for printing.
Network Printer: The Printer connected to the print server & the drivers should be available on the citrix server.
Local Printer: The printer connected to locally to the citrix server & the driers are installed for the print operation.
