Storage Devices

Correct Answer: CD-RW

DOS floppy disks contain essential file system structures including a boot record (for loading the OS), a file allocation table (for tracking file locations), and a root directory (for organizing files). However, virtual memory is a memory management technique used by modern operating systems to extend RAM using disk space, which DOS floppy disks do not implement.

Compact disks use laser technology to read data. The disk surface contains microscopic pits and lands that represent binary data, and a laser beam reflects off these patterns to read the information.

Floppy disks and hard disks are external storage devices because they are separate hardware components that can be connected to or installed in a computer system. Internal storage refers to components permanently inside the computer like RAM. Remote storage involves network-based or cloud storage. Floppy and hard disks are classic examples of external/peripheral storage media.

Mouse is not a storage device.

Magnetic tape secondary storage devices follow(s) the sequential mode of access.

CD-ROM (Compact Disc Read-Only Memory) uses optical technology - a laser reads microscopic pits on the disc surface. This distinguishes it from magnetic disks (like floppy/hard disks) that use magnetic patterns. Magneto-optical disks combine both technologies. CD-ROM is the classic example of optical storage technology.

Worm disks can be written only once and can be read many times. Therefore, they are called WORM (write once, read many) disks.

Boot sector  viruses are often transmitted by a floppy disk left in the floppy drive.

Correct Answer: Floppy disk
