What is Mass-Storage Structure?

hard disks and SSDs, which are used to store large amounts of data permanently

200

What is Disk Scheduling?

Disk scheduling is the method of deciding the order in which disk I/O requests are serviced.

300

What is Disk Partitioning?

partitioning divides a disk into multiple logical sections for better management and organization.

400

The smallest unit of data on a disk is called

 Sector

500

This problem occurs when multiple processes access shared data without synchronization.

What is a Race Condition?

Team2

100

types of storage devices?

1. Primary Storage (RAM, Cache)
2. Secondary Storage (Hard Disk, SSD)
3. Tertiary Storage (Optical disks, tapes) 

200

What are Disk Scheduling Algorithms?

• FCFS (First Come First Serve)

• SSTF (Shortest Seek Time First)

• SCAN

• C-SCAN

• LOOK

What is Swap Space?

Swap space is a portion of disk used as an extension of RAM when memory is full.

400

Seek time refers to

Time to move disk arm 

500

This is the total time required to access data from disk, including seek time, rotational latency, and transfer time.

What is Disk Access Time?

What is a HDD

Hard Disk Drive

200

What is RAID?

RAID (Redundant Array of Independent Disks)

300

Storage Caching

faster memory to improve performance.

400

which technique improves disk performance? 

Caching

500

his algorithm is an improved version of SCAN that only goes as far as the last request in each direction.

What is LOOK?

What is Disk Structure?

• Platters → Circular disks

• Tracks → Concentric circles

• Sectors → Smallest data unit

• Cylinder → Set of tracks across platters

200

What is Disk Formatting?

Disk formatting prepares a disk for data storage by dividing it into sectors and tracks.

300

Disk Reliability

data safety using techniques like RAID and backups.

400

Method used to track unused disk space.

What is Free Space Management?

500

if a disk scheduling algorithm always selects the nearest request, it may lead to this problem for far requests. 

What is Starvation?

Team5

What is Seek Time?

Seek time is the time required for the disk arm to move to the desired track.

200

 What is Free Space Management?

It is the method of tracking available storage space on a disk using techniques like bitmaps and linked lists.

300

secondary storage device?

Hard Disk

400

This algorithm moves like an elevator servicing requests in one direction.

What is SCAN?

500

his method of free space management uses a vector of bits to represent free and allocated blocks.

What is Bitmap (Bit Vector)?
