Hi, hidden folders can be displayed in MS windows in the folder options' settings.
Which storage device is used inside system unit to data store permanantly?
Permanent data is generally stored on the hard drive, but that can easily be erased. There are some areas on the hard drive that can not be erased or even accessed, this is generally the small amount of system volume information the computer needs to identify and manage the drive structure. Even a completely wiped hard drive has this space so that they can work with protocols issued to them by the system taking control of it.
EDIT: I forgot to mention that the CMOS and BIOS is built into the motherboard that stores permanent information, although the BIOS information can be reset by removing the small nickel-cadmium or lithium-oxide battery. This often only clears the security state, the date and time.
How to save a file on a CD-ROM?
You need to use CD burning software and burn the files on to a writable disk.
If you have windows XP or later, you can use windows explorer to burn files onto the disk like any other storage media
If a single hard disk is attached on a primary IDE channel what should the jumper be set to?
master if the ide cable has a single drive connection. if the ide cable has the master and slave connection. then set the drive to master with slave.
How do you recover cracked microSD card?
If it is physically cracked there is nothing to recover, the circuit connections no longer exist.
In the very very remote chance there is no damage to the chip inside, you might be able to find a data recovery company that will remove the broken plastic and connect directly to the chip to read it. However such companies will charge many thousands of dollars per card for this service. The data would have to be extremely valuable to be worth this expenditure!
What is the Difference between disk and a disc?
My first thought was "just the spelling" but it turns out it is a little more complicated than that.
They're pronounced the same, but, technically speaking, there is a distinct difference between a disc and a disk when it comes to computers.
- A disc refers to optical media, such as an audio CD, CD-ROM, DVD-ROM, DVD-RAM, or DVD-Video disc. Some discs are read-only (ROM), others allow you to burn content (write files) to the disc once (such as a CD-R or DVD-R, unless you do a mult-session burn), and some can be erased and rewritten over many times (such as CD-RW, DVD-RW, and DVD-RAM discs). All discs are removable, meaning when you unmount or eject the disc, it physically comes out of your computer - it is literally EJECTED.
- A disk refers to magnetic media, such as a floppy disk, the disk in your computer's hard drive, or an external hard drive. Disks are always rewritable unless intentionally locked or write-protected. You can easily partition a disk into several smaller volumes, too. Disks are usually sealed inside a metal or plastic casing (often, a disk and its enclosing mechanism are collectively known as a "hard drive").
Outside of the computer world, the difference IS only spelling - with disK being preferred in the USA and disC being preferred in the UK.
Advantages and disadvantages of using human memory as a way of of data storage?
We are like Goldfish, we swim around the bowl and notice a castle, we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle, we swim around again and we go OH! a castle.

What companies sell external storage devices?
External storage devices range from price and brand. However there are a lot of stores that carry them. Some including Best buy, Target, Walmart, Radio shack, and various places online.
Do emails show up on a hard drive if it is being backed up?
Yes. Everything that is backed up can be accessed. If the entire hard drive is backed up, then the emails will also be accessible. If the emails have already been deleted, they won't copy to the back-up, but they can still (probably) be recovered from the original drive if someone wants to go to the trouble. Computers are snitches.
What is the relationship between the CPU and input and output devices?
it is processing part of computer like brain in us
i/p and o/p devices: these are the interfaces between cpu and human man , its like sense organs in our body(i.e through sense organs we get information from surrounding, sent to brain to think, after that we send the reply of brain through sense organ)
Write detail note on secondary storage devices?
In modern computers, hard disk drives are usually used as secondary storage. The time taken to access a given byte of information stored on a hard disk is typically a few thousandths of a second, or milliseconds. By contrast, the time taken to access a given byte of information stored in random access memory is measured in billionths of a second, or nanoseconds. This illustrates the significant access-time difference which distinguishes solid-state memory from rotating magnetic storage devices: hard disks are typically about a million times slower than memory. Rotating optical storage devices, such as CD and DVD drives, have even longer access times. With disk drives, once the disk read/write head reaches the proper placement and the data of interest rotates under it, subsequent data on the track are very fast to access. As a result, in order to hide the initial seek time and rotational latency, data are transferred to and from disks in large contiguous blocks.
When data reside on disk, block access to hide latency offers a ray of hope in designing efficient external memory algorithms. Sequential or block access on disks is orders of magnitude faster than random access, and many sophisticated paradigms have been developed to design efficient algorithms based upon sequential and block access. Another way to reduce the I/O bottleneck is to use multiple disks in parallel in order to increase the bandwidth between primary and secondary memory.[3]
Some other examples of secondary storage technologies are: flash memory (e.g. USB flash drives or keys), floppy disks, magnetic tape, paper tape, punched cards, standalone RAM disks, and Iomega Zip drives.
The secondary storage is often formatted according to a file system format, which provides the abstraction necessary to organize data into files and directories, providing also additional information (called metadata) describing the owner of a certain file, the access time, the access permissions, and other information.
Most computer operating systems use the concept of virtual memory, allowing utilization of more primary storage capacity than is physically available in the system. As the primary memory fills up, the system moves the least-used chunks (pages) to secondary storage devices (to a swap file or page file), retrieving them later when they are needed. As more of these retrievals from slower secondary storage are necessary, the more the overall system performance is degraded.
Is a hard disk drive an input output or memory device?
In a short answer it is both.
I know this may sound mad but it is, don't forget it is a USB, a Universal serial bus.
UNIVERSAL being the main word....
Don't forget, when you save data to your external you are writing to it as an outport, through USB.
When you retrieve data from it, it now becomes an in - out port, USB again, hence you get something from it.
I hope that clears up your question.
If you Google the question, it may give you a better explanation or answer, than I have here..

A hard disk is type of magnetic storage device?
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.
What are step by step procedures to save on removable storage device?
This question is two questions in one.
(1) Save on removable memory buy buying the large capacity devices. They usually have a lower cost per GB.
(2) Save on removable memory by connecting it to the computer or device that holds the source data. Depending on your OS (operating system) if you connect it to a computer or device, the memory will appear as a drive on the computer or a source on the device. This is only general because I don't know if you are talking about flash, hard drives, memory sticks, SD, Zip, floppy, tape, with USB, proprietary or PC or etc. interfaces. Specific information is needed for a specific answer.

What element is used in CD disks?
Gadolinium is durable and is effective in letting lasers burn micronized bumps onto the surface of the disc. A micrometer is one millionth of a meter. This very small raised surface is what enables the CD player to read the disc and play music. Also, an 125 nanometer think sheet of aluminum is sometimes used to coat the micrometer sized bumbs.
What is an old fashioned storage device?
Old fashioned storage devices include punch cards, reel to reel tapes, and diskette drives.
