What is the difference between floppy disk and optical disk?

What is the difference between floppy disk and optical disk?

floppy disk is a magnetic storage medium with only 1.44 M capacity, while a CD is an optical disc that can store 700M CDs are based on physical dimples in the disk surface, or light-reactive ink layers for RW media. Floppies cannot store much at all A CD will hold more than 450 floppies.

What’s the difference between optical and magnetic storage?

Magnetic storage devices use “read/write heads,” electromagnets that detect (read) or change (write) the magnetization patterns on the disk. Optical storage devices use lasers to read the reflections in the disk or “burn” the data pattern into the disks.

What is the basic difference between magnetic tapes and floppy disks?

Both are non-volatile storage. Despite these similarities both differs in many aspects from their appearance to their working, their cost and much more. The basic difference between magnetic tape and magnetic disk is that magnetic tape is used for backups whereas, magnetic disk are used as secondary storage.

What are the key differences between a diskette and a hard drive?

Hard disk offers a large storage facility. It is faster than floppy disks. It works as a primary media for storing data and programs. The capacity of the computer hard disk is from 2 to 500 GB and more.

What are the strengths of a floppy disk?

Advantages of a floppy disk :

• Small.
• Easy to carry.
• Cheap.
• Easy to transport and handle.
• Data on a floppy disk device can be write-protected from being changed accidentally.
• Floppy disk can be used to transfer data from one computer to another computer.
• Portable and inexpensive.

What can a floppy disk be used for?

Floppy disks are used for moving information between computers, laptops or other devices. Some early digital cameras, electronic music instruments and older computer game consoles use floppy disks. Floppy disks are inserted in to a floppy disk drive or simply floppy drive to allow data to be read or stored.

What is floppy drive failure?

Floppy disk failure typically occurs at boot up if the system BIOS chip cannot initialize the floppy drive. This might happen if the drive is not enabled. On most computers, this can be checked by looking at the BIOS settings, which can often be done by pressing the DELETE key during the boot process.
