- The internet was created to grow and evolve over time.…The framework and protocol that built the internet,…TCP and IP, have evolved and grown…to support billions of devices and…enable them to connect with each other.…Through the use of packets, information can be sent…through a fault-tolerant network,…and then be verified for reliability of information…to ensure that information is sent quickly and accurately.…Through the internet protocol,…every device on the internet…has a unique code, or IP address…that is used to route packets of information.…
Using IP before, and now IPV6, there are enough addresses…to assign to an almost infinite number of devices…as the internet grows and expands.…But to make that easier for use to remember and work with,…we use words and phrases, called domains,…that are translated to these IP addresses…using DNS, or Domain Name Servers.…When we access a server over the web using a browser,…we are sending information using HTTP.…
The web server has a program, a DAEMON,…that is constantly listening for HTTP requests,…
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
