IB Computer Science - TOPIC 1 - SYSTEM FUNDAMENTALS

What is the purpose of a feasibility study in system development?

• To select the best information systems from each company

• To evaluate and analyze a project based on various criteria

• To decide on the color scheme of the new system

• To determine the number of employees needed for the project

What is the main benefit of Software-as-a-Service (SaaS) solutions?

• Low initial cost and scalability

• High maintenance cost and limited accessibility

• Dependence on a third party and lack of security

• Complex installation process and high hardware requirements

What is the primary purpose of user documentation in software development?

• To limit access to the software

• To increase the cost of implementation

• To confuse users with technical jargon

• To help users understand and utilize the product effectively

What is the difference between validation and verification in software testing?

• Validation confirms if the product meets customer needs, while verification confirms if it meets specifications

• Validation confirms if the product is user-friendly, while verification confirms if it is secure

• Validation confirms if the product complies with regulations, while verification confirms if it is appropriate for use

• Validation confirms if the product is developed correctly, while verification confirms if it is the correct system

What is a common cause of data loss related to computer viruses?

• Very common cause of data loss

• Cause of data loss due to natural disasters

• Cause of data loss due to administrative errors

• Rare cause of data loss

What is a failover system in computer science?

• A system that requires human intervention to switch to a spare computer

• A system that automatically switches to a spare computer upon failure

• A system that never encounters hardware failures

• A system that fails to switch to a spare computer upon failure

What is the purpose of a prototype in the design process?

• To complicate the design process and slow down development

• To attract client attention and provide an idea of the final product

• To eliminate the need for user feedback

• To discourage user participation and delay the project

What is the main advantage of using a system flowchart in analysis activities?

• To define the specific customer requirements of a computer system

• To facilitate statistical analysis and data comparison

• To show the flow of data through a system and hardware details

• To represent various computer programs, files, and databases

Why is iteration important during the design process?

• To speed up the design process without any revisions

• To avoid involving end-users in the design process

• To allow designers to reconsider choices and improve the design

• To ensure the final product is perfect in the first attempt

What are the consequences of failing to involve the end-user in the design process?

• The system may not solve the intended problem or may deal with issues outside the scope

• The system will be perfectly aligned with stakeholder goals

• The project will be completed faster without user involvement

• The system will automatically adapt to user needs without feedback
