  6. What is web browser?
    • Answer:
    • A web browser is a software application used to access and view websites on the internet. It allows users to retrieve, display, and interact with web pages, which can include text, images, videos, and other multimedia content. Common web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari. They work by interpreting and rendering HTML, CSS, and JavaScript code from web servers, enabling users to navigate the web via hyperlinks and other interactive elements.

Long Questions:

  1. Describe several different environments in which multimedia might be used, and several different aspects of multimedia that provide a benefit over other forms of information presentation.
  2. What is Virtual Reality(VR)?

Answer: Virtual Reality (VR) is a cutting-edge convergence of technology and creative invention in multimedia. It involves using devices like goggles, helmets, gloves, and other interfaces to immerse users in a lifelike experience. In a VR environment, users can interact with the virtual world; for example, moving closer to an object, turning their head to change their viewpoint, or using their hands to interact with virtual objects.

On the World Wide Web, standards for transmitting virtual reality worlds or scenes in VRML (Virtual Reality Modeling Language) documents (with the filename extension .wrl) have been developed. Intel and software makers such as Adobe have announced support for new 3-D technologies.

VR has practical applications in various fields. For example, high-end flight simulators allow pilots to practice flying aircraft, such as F-16s and Boeing 777s, in a controlled virtual environment before attempting real-life operations. Similarly, merchant marine officer training uses simulators to teach the complex processes of loading and unloading large vessels.

Overall, VR represents a significant extension of multimedia, combining imagery, sound, and animation with interactive feedback, making it one of the most immersive forms of interactive multimedia.
