Two possibilities that when you flip the coin you would get heads or tails.
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.
What is the difference between super disk and hard disk?
The super-disk or LS-120 and its derivatives are a removable disk more akin to a zip disk or floppy disk. They are designed to be easily swapped from machine to machine. Physically they resemble a floppy disk in that it has an internal platter is composed of flexible plastic encased in a hard case for protection.
A hard disk is designed to reside permanently in the same computer and acts as the primary storage & boot device. A hard disk is a semi-sealed device inside the computer which has several rigid aluminum (usually) platters permanently encased within an aluminum shell.
Hard disks can read & write data at a much faster rate than superdisks.
Hard disks can store a great deal more data than superdisks.
Superdisks are generally considered to be obsolete these days, with thumb drives cd-rws and dvd-rws having taken their place as easily portable storage devices.
What are the advantages and disadvantages of 3.5'' Floppy disks?
Advantages - None
Disadvantages - TINY TINY TINY Storage
- Rubbish size/storage ratio (size of disc)
- they are obsolete surely
I built a new PC and didnt include a disc drive because they are pointless
for the price of a disc drive you can get a 8 gig USB stick
Insert copy of data disk into drive A?
It sounds like you are trying to install a program, and it needs the data disk to be put into A Drive.
Data can be stored on floppy disk, hard disk, memory stick, CD or DVD.

How many pins does a PATA cable have and What is the maximum recommended length of a PATA Cable?
40 Pins and 80 wires. Maximum recommended length is 18" but can purchase 24" cables.
Is disk controller a part of system unit?
If by "system unit," you mean the main part of the computer, then yes. In the past, all disk controllers were plugged into the motherboard. Nowadays, the motherboards all come with disk controllers, at least for SATA (and sometimes SAS) hard drives.
You dont have a floppy drive how do you add pics from a floppy disk?
By buying a floppy drive. You can buy an external USB floppy drive for under $50.
FAT
Is floppy disk store sequential access files?
False. It is considered as direct access storage devive
Is it allege to take PC hard drive from a scarp yard?
If you mean is it illegal to take a hard drive from a scrap yard- it may be. The scrap in the scrap yard belongs to the scrap yard- like everything else there. Taking the property of someone else is called theft. However, it the operator of the scrap yard sells or gives the hard drive to you, you should be OK.

Can you open floppy disks saved in Windows 98 in XP using open office?
No reason why not. Windows XP should be able to read disks created with Windows 98 without any problems. OpenOffice is capable of reading a wide variety of files.
Since higher storage and media devices have been released such as USB's and CD's, floppy disks have become outdated due to the maximum capacity that is now available to computers. In the 1990's floppy disks were very popular and widely used.
What is a range of a storage capacity of a floppy disc?
Eight inch floppy disks held about 160 KB. Later popular 5-1/4 inch floppy disks initially held 360 KB, but later a 1.2 MB version was introduced. Finally hard cased 3-1/2" floppy disks came out, which held 1.4 MB.
What does formatting a floppy do?
formatting a floppy lets the computer understand it and then, it will be able to read and write data to it. this should only have to be done once for each computer you want to be able to read and write data off of.
What is the difference between delete and format?
Formatting prepares a drive to accept new data. This involves wiping the whole drive (or partition) and all the information on it.
Delete, just removes the index to where a particular file was actually stored on the disk. It's a bit like, instead of tearing a page out of a book, you just cross out the index that refers to that page. That's how Undelete programs can find the file again.
The old data however, can be overwritten, by new stuff being stored and thus losing the data forever.
Can you use a boot able floppy disk created in Windows XP to boot a Windows 98 computer?
I think you can but on your Windows 98 Computer make sure that in your BIOS the Floppy Drive is the very top one.
Plus to get to the BIOS depends on your Computer. Here are the shortcuts that I know of to get to the BIOS:
F2 , Del (or Delete) , or F10
Just experiment with the keys until you get to the BIOS.

What is read only memory storage device-afloppy disk bhard disk c CDROM dnone?
CD-ROM is a read-only storage medium (CD-ROM is an acronym for Compact Disc Read-Only Memory). Floppy disks and hard-drives are both writeable mediums. Note that CD-R (Compact Disc Recordable) and CD-RW (Compact Disc Re-Writeable) are not the same as CD-ROM.
How can you tell which side of of a hard drive data cable connects to pin 1 on the drive?
Most, though not all, cables indicate the pin 1 side by coloring the outermost wire on that side differently from the rest.
Also, on some cables there's a blocked hole in the middle ensuring that the cable will only fit on the drive one way.
What is floppy disk management?
It's higher than Floppy Disk Associate, but not quite Floppy Disk Board of Directors.
