Join Doug Winnie for an in-depth discussion in this video Hypertext and HTML, part of Computer Science Principles: The Internet.
- When you read a book,…you go through information from beginning to end.…As books got more complicated…they added things like a table of contents.…So you could scan a list of chapters…and know where in the book you needed to go.…With more complicated books there's an index…where more common words or phrases…that people will want to know are listed in the back…with page numbers where you can go find out…about that specific phrase or topic.…But in the digital world these concepts…are a little limited.…When you are reading about a topic…you might be at word or phrase you want to know more about.…
It would be great if you could just…avoid having to go to a table of contents, or an index,…and just click it to jump right to that information.…That is how hypertext works.…If I have a document that talks about fruit…I'll read about what makes a fruit a fruit,…and how fruits grow and seed and sprout.…On that page I can have additional information…about specific fruit like an apple, a pear, or a banana.…But instead of having that information on this specific page…
This course is the second in our Computer Science Principles series, designed around the AP Computer Science Principles (CSP) curriculum. It is a great foundation for anyone, at any age, to prepare for careers in technology and computer science. Understanding basics like the Internet will help you understand the interplay between hardware, software, data, networks, and the people that use them.
- How the Internet was born
- Sending and receiving information on a computer
- IP addressing
- DNS, routers, and packets
- Identifying web servers with URLs
- HTTP and HTML
- Encrypting data that's sent over the Internet
