What is a key characteristic of real-time processes in multimedia OS?

• They must complete tasks within a specific deadline

• They can be delayed

• They require less memory

• They are not time-sensitive

Answer explanation

Real-time processes in multimedia OS are critical as they must complete tasks within a specific deadline to ensure smooth operation and user experience. Delays can lead to performance issues, making timely execution essential.

What does fair scheduling in multimedia OS aim to achieve?

• Balance timely processing with fairness

• Maximize CPU usage

• Minimize memory usage

• Eliminate all delays

Answer explanation

Fair scheduling in multimedia OS aims to balance timely processing with fairness, ensuring that all tasks receive appropriate attention without starving any process, which is crucial for maintaining quality in multimedia applications.

Which of the following is NOT a state of a process in multimedia OS?

• Idle

• Blocked

• Running

• Suspended

Answer explanation

In multimedia OS, process states typically include Idle, Blocked, and Running. 'Suspended' is not a standard state; it refers to a process that is temporarily halted, not actively managed like the others.

What is the purpose of resource scheduling strategies in multimedia OS?

• To reduce the complexity of the OS

• To ensure timely media access and minimize seek time

• To allocate resources based on user preferences

• To increase the number of processes

Answer explanation

Resource scheduling strategies in multimedia OS are crucial for ensuring timely media access and minimizing seek time, which is essential for smooth playback and overall performance in multimedia applications.

What does the term 'Quality of Service' (QoS) refer to in multimedia OS?

• The performance and reliability of media delivery

• The speed of data processing

• The quality of the user interface

• The aesthetic design of multimedia content

Answer explanation

The term 'Quality of Service' (QoS) in multimedia OS refers to the performance and reliability of media delivery, ensuring that audio and video streams are transmitted smoothly and without interruption.

Which scheduling algorithm prioritizes tasks with the nearest deadline?

• Earliest Deadline First

• Least Laxity First

• Rate Monotonic Scheduling

• Shortest Job First

Answer explanation

The Earliest Deadline First (EDF) scheduling algorithm prioritizes tasks based on their deadlines, selecting the task with the nearest deadline to execute next. This makes it optimal for real-time systems.

What type of file system is efficient for streaming in multimedia OS?

• Non-sequential storage

• Sequential storage

• Distributed storage

• Hierarchical storage

Answer explanation

Sequential storage is efficient for streaming multimedia because it allows data to be read in a continuous flow, minimizing seek time and maximizing throughput, which is essential for smooth playback.

Which of the following is a characteristic of Multimedia Database Management Systems (MDBMS)?

• Requires manual data entry

• Supports only text data

• Handles large, unstructured data

• Is limited to audio files only

Answer explanation

Multimedia Database Management Systems (MDBMS) are designed to handle large volumes of unstructured data, such as images, audio, and video, making them suitable for diverse multimedia applications.
