Lesson 3 Practice

What is a Graphical User Interface (GUI) and how does it differ from a Command-line Interface (CLI)?

• A GUI uses text commands, while a CLI uses icons and symbols.

• A GUI uses icons and symbols, while a CLI uses text commands.

• Both GUI and CLI use only text to operate a computer.

• Both GUI and CLI use only icons and symbols to operate a computer.

Explain why a systematic approach is beneficial in troubleshooting.

• It allows for random guessing to solve problems.

• It ensures that steps are repeated exactly and nothing is left out.

• It makes the process faster by skipping unnecessary steps.

• It relies on intuition rather than a fixed plan.

Describe a scenario where swapping in working parts from other computers could be an effective troubleshooting strategy.

• When a computer is running slow due to software issues.

• When a specific hardware component is suspected to be faulty.

• When the computer has a virus.

• When the user interface is not responding.

What is the primary focus of Human-Computer Interaction (HCI)?

• To make computers faster.

• To improve how users work with computers.

• To increase the storage capacity of computers.

• To develop new programming languages.

How can creating a diagram help in troubleshooting a computer problem?

• It provides a visual representation to trace the problem.

• It automatically fixes the problem.

• It replaces the need for a systematic approach.

• It confuses the troubleshooting process.

Why might a user choose to use a Command-line Interface (CLI) over a Graphical User Interface (GUI)?

• CLI is easier to use for beginners.

• CLI allows for more precise control and automation.

• CLI is more visually appealing.

• CLI requires less typing than GUI.

What is debugging in the context of computer programming?

• Installing new software.

• Finding and correcting errors within a program.

• Designing a new user interface.

• Upgrading hardware components.

How can checking software settings and compatibility help in troubleshooting?

• It ensures that the software is up to date.

• It identifies if the software and hardware can work together.

• It speeds up the computer's performance.

• It automatically resolves all software issues.

In what way can getting help from a more knowledgeable troubleshooter be beneficial?

• It guarantees that the problem will be fixed immediately.

• It provides additional expertise and perspective on the problem.

• It eliminates the need for any troubleshooting steps.

• It is only useful for hardware issues.

What is the role of a User Interface (UI) in a computing system?

• To store data.

• To operate the computer.

• To increase processing speed.

• To connect to the internet.
