WIF3008 Pop Quiz - Lecture 1: Fundamentals of Real-Time Systems

These are some of the classification of a computer system, except

• Mainframes

• Grid Computing System

• Real-Time System

• Quantum Computing System

Real-time system must meet strict timing constraints. Tasks are required to complete within a defined time (deadline). Missing a deadline may lead to ___________.

• system failure

• system rebooting

• system on-hold

• system shut-down

A __________ is one in which a few missed deadlines will not lead to total failure but missing more than a few may lead to complete or catastrophic system failure.

• firm real-time system

• hard real-time system

• soft real-time system

Synchronous events are those that occur at unpredictable times in the flow-of-control, such as that represented by the decision box.

• False

• True

Which of these statement is false?

• RTS are highly deterministic. The system must guarantee that tasks will be executed in a predictable manner and completed within known time bounds.

• RTS typically uses more flexible scheduling algorithms (e.g., round-robin, multi-level queue scheduling) aimed at maximizing throughput, resource utilization, or fairness rather than focusing on deadlines

• RTS prioritizes tasks based on urgency and deadlines. Higher-priority tasks can preempt lower-priority ones to ensure deadlines are met.

• RTS requires careful resource allocation (CPU, memory) to ensure that critical tasks have enough resources to meet their timing constraints.
