Solved in 2 steps
- Operating systems will always try to store a file's successive blocks on the next available disk blocks. When it comes to magnetic disks, why is this so important?Operating systems make an effort to save individual pieces of a file in a sequential fashion on disk. So what if we use magnetic disks for it?SSDs: necessary even if you don't use them? Is this anything that we can figure out?The process of___ arranges the disk's surface into addressable areas and sets up the disk's basic directory tree structure. a. Partitioning b. Time slicing c. Booting d. Formatting
- When a file is saved to disk, it is the responsibility of the operating system to ensure that the blocks are placed in the appropriate order. Why is it absolutely necessary that this be done while talking about magnetic disks? If solid-state drives (SSDs) were used instead, would it make a difference, or would it be irrelevant? What's the deal?Storage locations on a disk that are divided into pie-shaped sections?Yellow – Represents whether the partition is bootable (00 means not active)Green – This is the starting head 20, cylinder 21 and sector 00 (in little endian) (not important because itlimited the theoretical disk sizes)Blue – Represents the filesystem (important) Red – Address of the end of the partition on the diskBrown/Green - Logical Block Address of first sector in the partitionPurple- The number of sectors on the drive in little Endian (we can calculate the correct drive size basedon this value if we know the sector size (512 bytes in this case)) How large is the partition (MB)? ___________________________________ {show your calculations} yellow{80} green{21 00} blue{07} red{DD 1E 3F} Brown/Green{00 08 00 00} purpule {00 AO OF 00}
- Can read or modify the contents of a disk file by reading and writing memory locations?A new disk is prepared by a computer system in which disk is to be used, by a process known to be a. Disk generation b. Disk formulation c. Disk formatting d. Disk transformationConsecutive blocks of a file should be placed on the same disk block by operating systems. For what reason is it so critical to do so with magnetic disks?
- 188. The _______ is that part of main memory available for storage of copies of disk blocks. a. Buffer b. Catalog c. Storage d. Secondary storageThe process of rewriting parts of a file to contiguous sectors on a hard disk to increase the speed of access and retrieval.A. FragmentationB. DefragmentationC. BothD. NoneOperating systems often make an effort to fit as many successive blocks of a file into a single disk block as is physically possible. How come this is so important for magnetic disks?
