What critical data structure is stored in the very first physical sector (Master Boot Record) of a hard disk drive?
In what logical form do operating systems organize stored data on secondary storage devices?
What is the total formatted storage capacity of a standard 3.5-inch High-Density floppy disk?
Upon executing DOS INT 21h Service 3Dh (Open File), if the target file cannot be opened, how does the system signal the error condition?
Which disk management operation is performed by BIOS Interrupt 13h Service 03h (AH = 03h)?
Fill in the three missing words in the following passage from CS401 Secondary Storage: 'BIOS sees the disks as a combination of sectors, tracks, and [Blank 1], as a raw storage device without concern to whether it is reading a file or directory. [Blank 2] provides the simplest and most powerful interface to the storage medium. However this raw storage is meaningless to the user who needs to store his files and organize them into [Blank 3].'
Which system software component provides a high-level, logical view of a storage medium (such as files and directory structures) rather than raw physical sectors?
Which software component provides a high-level, logical view of storage media (such as files and directory trees) rather than raw physical sectors?
How does the system ROM BIOS view physical secondary storage media such as hard disks and floppy drives?
