Right Answer: To find the major hardware components of a computer, you can:
1. Check the system specifications in the operating system settings (e.g., Device Manager in Windows, About This Mac in macOS).
2. Use command-line tools like `lscpu`, `lsblk`, or `lshw` in Linux.
3. Use third-party software like CPU-Z or Speccy for detailed hardware information.
4. Physically inspect the computer case for components like the CPU, RAM, GPU, and storage drives.
Right Answer: I would prioritize the tasks based on their importance and deadlines, focusing on the most critical ones to complete within the available time.
Right Answer: Graphics refer to visual images or designs created using computer software, which can include illustrations, photographs, and text, used to convey information or enhance the aesthetic appeal of a project.
Right Answer: Document Style Semantics and Specification Language (DSSSL) is a language used for specifying the style and formatting of documents written in SGML (Standard Generalized Markup Language) and XML. It allows for the separation of content from presentation, enabling the transformation and rendering of documents in various formats.
Right Answer: The selector `h1` targets all `<h1>` elements, `.warning` targets all elements with the class "warning", and `#footer` targets the element with the ID "footer".
Right Answer: Block elements take up the full width available and start on a new line (e.g., `<div>`, `<h1>`). Inline elements only take up as much width as necessary and do not start on a new line (e.g., `<span>`, `<a>`). Inline-block elements are similar to inline elements but can have width and height set, and they respect margins and padding (e.g., `<img>`, `<button>`).
Right Answer: JavaScript closures are functions that remember their outer scope even when the function is executed outside that scope. They work by capturing the variables from their surrounding environment, allowing access to those variables even after the outer function has finished executing. This is useful for data encapsulation and maintaining state in asynchronous programming.
Right Answer: The box model in CSS describes the rectangular boxes generated for elements in a document tree and consists of four areas: content, padding, border, and margin. The content is the innermost area, surrounded by padding, then the border, and finally the margin, which is the outermost area.
Right Answer: `var` is function-scoped or globally-scoped and can be re-declared and updated. `let` is block-scoped, can be updated but not re-declared in the same scope. `const` is also block-scoped, cannot be updated or re-declared, and must be initialized at the time of declaration.
* **Individuals and interactions** over processes and tools.
* **Working software** over comprehensive documentation.
* **Customer collaboration** over contract negotiation.
* **Responding to change** over following a plan.
That is, while the items on the right have value, we value the items on the left more.
Right Answer: During a sprint, I generally avoid scope creep. If a change request is small and doesn't impact the sprint goal, the team can discuss and decide if it can be included. If the change is significant, it goes into the product backlog to be prioritized for a future sprint.
Right Answer: To facilitate effective sprint retrospectives, I would:
1. **Set the Stage:** Create a safe and open environment where the team feels comfortable sharing.
2. **Gather Data:** Collect information about what went well, what didn't, and any challenges faced during the sprint.
3. **Generate Insights:** Facilitate a discussion to identify root causes and patterns.
4. **Decide on Actions:** Collaborate to define specific, actionable, measurable, achievable, relevant, and time-bound (SMART) improvements.
5. **Close the Retrospective:** Summarize action items and assign owners.
6. **Follow Up:** Track progress on action items in subsequent sprints to ensure continuous improvement.
Right Answer: I've used tools like Jira, Azure DevOps, and Trello for Agile project management. I choose them based on project needs; Jira for complex workflows and robust reporting, Azure DevOps for integrated development environments, and Trello for simpler, visually-oriented task management.
