MS-N2
Network Concepts
Identify and use network terminology; apply networks to solve problems involving shortest paths and minimum spanning trees.
Sample questions
- 1.Use Prim's algorithm to find the minimum spanning tree of the given network. State its total weight.
Exam weighting
3–5 marks — Prim's / Kruskal's and shortest path problems.
Common student mistakes
- ·Confusing weighted and unweighted shortest-path algorithms
- ·Not checking that a minimum spanning tree includes all vertices
MS-N3
Critical Path Analysis
Use critical path analysis to schedule tasks and determine the minimum time to complete a project.
Sample questions
- 1.Given the activity table, construct a network diagram and identify the critical path and minimum completion time.
Exam weighting
3–4 marks — drawing network diagrams, float times.
Common student mistakes
- ·Forgetting to compute the float time for non-critical activities
- ·Misidentifying the critical path when two paths have equal length
