Answer explanation

Pipeline composition See Topic: Batch computing.

What is the primary optimization goal of batch systems?

• Lowest possible latency per request
• Fairness across interactive users
• Maximizing overall throughput of jobs
• Minimizing network hops

Answer explanation

Throughput focus See Topic: Batch computing.

Time-sharing primarily provides…

• Exclusive CPU access for one user until completion
• Short time slices among many users for interactive responsiveness
• Only background job execution overnight
• Deterministic deadlines for critical control

Answer explanation

Core idea See Topic: Time-sharing computing.

A short CPU allocation given to a process in time-sharing is called a time ______.

Answer explanation

Vocabulary See Topic: Time-sharing computing.

In real-time computing, a result is correct only if…

• It uses the least CPU cycles
• It is produced within the required time bound (deadline) and is logically correct
• It maximizes throughput
• It uses no interrupts

Answer explanation

Definition with deadline See Topic: Real-time computing.

Which statement describes hard real-time?

• Missing a deadline degrades quality but is acceptable
• Missing a deadline is a system failure
• Deadlines are not defined
• Only background jobs run

Answer explanation
