How much storage does a CD-rom have?
A CD-RM used to be able to store up to 650MB of information. CD-ROMs are now able to store up to 700 MB of data or 80mins. of Audio. and hold music like mac lethal and AC/DC
Why are floppy disks not suitable for permanent storage?
Because it is easily erased because it is on magnetic tape so if it were to go near a magnet it would be erased.

They may also degrade with time - but whether that is more serious than the computer manufacturers making the equipment obsolete within only a few years so you can't read them anyway, I'll leave others to decide!
What is the difference between USB and a floppy disk drive?
USB is a standardized bus for connecting exernal peripherals (printers, scanners, keyboards, mice, flash drives, hard drives, etc...) to a computer. A floppy disk drive is an outdated method of storing data. It uses a thin sheet of coated plastic, usually inside a firmer plastic shell, to store data.
Do people use floppy disks today?
I still use floppy disks for backing up some small files, like Word Documents, Text Files, and small "WAV file sound effects when I don't have any CDs or my flash drive is full.
I still have some old DOS games on floppy that I still play sometimes, though I have them backed up on CD, but I still play the games on Floppy if I can't find the CD.
I also maintain an Emergency Boot Disk, in case my computer crashes or gets hit by a virus and I need to go into DOS to resurrect the computer.
My School has older computers in the Social Studies computer lab that has computers with floppy disks, but I've never used them, I have a Pen drive for that! But I've seen the School IT guy use them to keep these old machines going.
My current Workplace has a few older printing presses that need to be "calibrated" using 4 unmarked floppy disks, in order, or the margins will be off and that docked from your pay. Luckily they copies of copies of copies of the original disks and they are different colors, so they always go Yellow-Blue-Black-Grey, Yellow-Blue-Black-Grey, etc.
The U.S. Government has a protocol that sensitive, classified military documents, such as Nuclear Defense Information, that was written in the 1980s, when floppy disks were the only way to distribute computer information. It would cost so much to transfer all the information to a more modern format, dispose of the old disks and write new protocol that they continue to use floppy disks to distribute this information in 2010 as they did in the 1980s.
There are a lot of older technology still in daily use that requires the use of floppy disks, like industrial equipment and cash registers. I went shopping early at a thrift store (shortly after they opened) once and I had to wait for them to boot the register from 3 floppy disks to buy some clothes, this was in 2008, too!
I remember saving some songs I had composed on an electric keyboard using a integrated floppy disk and could play them as "MIDI" files either on the keyboard or on my computer! But that was back in 2003.
Older digital cameras store their pictures on a floppy disk, also. Most of those cameras are of better quality than the modern, cheap flash-based digital cameras, film-like without the film. Though many of these have been abandoned in favor of new, flsh-based cameras.
Many Developing and Third-World countries use older, obsolete computers that have no other way to transfer and store data than floppy drives, after the developed world deemed them to be "obsolete" and were considered "junk" their still serving Latin America, Africa, Asia and the Islands as daily work-horses in homes, schools, hospitals, businesses and government offices.
As you can see floppy disks are still used, just usually as a legacy system, once all these technologies clunk out, they will be obsolete.

Two advantages that main memory has over magnetic disk storage?
Faster access time(uses data bus directly and not through any controller) and no moving parts
- Improvement in the uniformity of the magnetic filmsurface to increase disk reliability.
- A significant reduction in overall surface defects to help reduce read/write errors.
- Ability to support lower fly heights (described subsequently).Better stiffness to reduce disk dynamics.
- Greater ability to withstand shock and damage
What must happen before any data can be read or written on a hard disk?
the right place on the hard disk has to be found, then the read/write head must be placed there, then the sector (a small part of the hard disk) is read or written, if it's read, the data is moved into the memory, maybe by the DMA (Direct Memory Access) Controller. Is it's a write operation, the data must first be given to the Hard Disc Controller.
No not really, it's the brain.
CPU is the Central processing Unit which receives input via input devices like keyboard, mouse , scanner, mic etc. It's main job is to process the input and send to the relevant o/p device.
It controls the flow and process of instructions, in time with a clock pulse.
It needs to handle both input and output of binary data.
What is the capacity of a floppy diskettes?
The last generation of floppy disks were 3.5 inches in diameter. They were capable of holding 1.44 megabytes of data. By comparison, a Compact Disk holds about 650 megabytes.
What color or stripe down one side of a cable marks this side of the cable as pin 1?
Usually an arrow pointing to it, or a number 1 on the connector. It's also on the side with the red wire. And most boards are keyed with a slot on the side of the female part, and extrusion on the male connector... so it can only be inserted the proper way.
How do you transfer a photo from a floppy disk drive to a computer?
If you have a CD Burner such as Nero or Roxio (Sonic solutions), start the program, choose Data CD and then then choose from the task bar "Add Data" and then select the drive where your data is, and follow the instructions.
Who invented the floppy disk in 1967?
The very first CD player was invented by James T. Rusell. James T. Russell, a senior scientist at the Pacific Northwest Laboratory, invented the technology for the compact disc in 1965. By 1985, Russell had earned 26 patents for various innovations with CD-ROM technology.
Example of a magnetic storage device?
MAGNETIC Storage Media are the Hard disk drivestypesthat make use ofMAGNETIC PLATTER and Read\Write Sensor (Read - Sensing Polarity, Write - Altering theinclinationi.e. sensor attracted or repelled)over the microscopic area on the Platter) for storing Digital Information in form of Binary Signals.
Unplug the power cord
Where is the floppy disk drive located?
You would have to search online for an external floppy disk drive or buy an old PC that has one. In the "old days" every computer had a built-in floppy drive. It would always be right in the front. About a 4" wide slot.
Why is a flash drive better than a floppy disk?
Bigger storage space, smaller chance of files getting corrupt or hardware getting damaged
Most floppy disks will come pre-formatted. All floppy disks need to be formatted to be usable.
There are many disadvantages of magnetic tape.
1. Mag tape is in physical contact with the recording heads, causing friction and wear.
2. Magnetic tape is an analog medium, even when digital data is being stored.
3. Tape can stretch or break, or lose its magnetic data due to age, heat or the Earth's magnetic field.
What is the difference between floppy disc and hard drive?
A hard disk (HD for short) and floppy disk (FD for short) both work in the same manner, except that on can hold more information. Both are a type of magnetic media which can have information written and erased many many times. A lot better than paper when you write something and erase many times, that paper gets thin, then GAME OVER! I am including a link to better explain this from "howstuffworks". I really love that site. I could spend all day on there reading about anything! About their differences. the most common floppy disks only hold about 3.14MB of data. Where an electric HD can hold almost any amount up to several terabytes today!! That is huge. The FD uses a mechanical motor to move the read/write armature that hovers over the FD material (most comparable to cassette tape material). This is where it changes the magnetic properties of the tape material, and bingo, last night's report is saved! The HD works in a similar fashion. HD's have dense metallic disks inside that can spin at thousands of RPM's (rounds per minute). As the disks spin a similar Armature that is is surrounded by some really powerful magnets changes the magnetic properties of the dense metallic disks and Bingo, last night's report, music, and the whole operating system is spinning virtually forever. That is the basics. Hopefully that sums things up in a nutshell. Visit that site at howstuffworks to really see a more in depth look at floppy disks & hard drives!
