Software Engineering Review
Questions
Course Introduction
Software Engineering is an interdisciplinary course that introduces students to the fundamental principles, methods, and tools used in the development of high-quality software systems. The course covers key topics such as software development life cycles, requirements analysis, system modeling and design, testing, maintenance, project management, and quality assurance. Emphasis is placed on both technical and collaborative skills, including teamwork, communication, and the use of industry-standard tools and practices. Through practical assignments and projects, students gain hands-on experience in designing, implementing, and evaluating robust software solutions, preparing them for professional roles in software development and engineering.

Q1) A ________ is a graphical representation of a project that shows each task as a horizontal bar whose length is proportional to its time for completion.
Answer: Gantt chart
Q2) Briefly define and compare Gantt charts and network diagrams.
Answer: A network diagram is a graphical depiction of project task activities and their interrelationships.The distinguishing feature of network diagram is that the ordering of activities is shown by connecting an activity with its predecessor and successor activities.A Gantt chart is a graphical representation of a project that shows each task activity as a horizontal bar whose length is proportional to its time for completion.The two charts have features that enable them to more easily demonstrate certain aspects of a project more so than the other chart.Gantt shows the duration of activities;a network diagram shows the sequence dependencies between activities.Gantt shows the time overlap of activities;a network diagram does not show time overlap but does show what activities could be done in parallel.Some forms of Gantt charts can show slack time available within an earliest start and latest finish duration;a network diagram shows this by data within activity rectangles.
Q3) ________ is the shortest time which a project can be completed.
