4. Networking and Communications

  • Computer Networks: Involves designing and managing communication networks like the Internet, LANs, and WANs.
  • Cloud Computing: Deals with delivering computing services over the internet, including storage, processing, and software.
  • Internet of Things (IoT): Networks of physical devices embedded with sensors and software to connect and exchange data.

5. Artificial Intelligence (AI) and Machine Learning (ML)

  • Machine Learning: A subset of AI focused on algorithms that allow computers to learn from data and make decisions.
  • Natural Language Processing (NLP): Enables computers to understand, interpret, and respond to human language.
  • Computer Vision: Focuses on enabling machines to interpret and process visual information.
  • Robotics: AI-powered machines capable of performing tasks autonomously or semi-autonomously.

6. Human-Computer Interaction (HCI)

  • User Interface (UI) Design: Designing graphical and interactive elements that users interact with on a computer.
  • User Experience (UX): Focusing on the overall experience of a person using a system, including ease of use and efficiency.
  • Virtual Reality (VR) and Augmented Reality (AR): Creating immersive environments that interact with the real or virtual world.

7. Data Science and Big Data

  • Data Analytics: Analyzing large sets of data to derive actionable insights.
  • Big Data: Handling and processing extremely large datasets using technologies like Hadoop and Spark.
  • Data Mining: Discovering patterns and knowledge from large datasets.

Image
        HTML (HyperText Markup Language) is the standard language used to create and design web pages. It structures the content of web pages by defining elements such as headings, paragraphs, links, images, and other multimedia. HTML is composed of tags enclosed in angle brackets (e.g., <tag> ), and most tags come in pairs, with an opening tag (e.g., <p> ) and a closing tag (e.g., </p> ), though some tags are self-closing (e.g., <img /> for images). Here are the key components of HTML: Elements :                               The building blocks of an HTML page, consisting of tags and the content they wrap.                                                   <p>This is a paragraph.</p> Attributes...
