Join Doug Winnie for an in-depth discussion in this video The Internet Protocol and IP address, part of Computer Science Principles: The Internet.
- When you send a letter or package,…you need to provide an address.…The address needs to be understood by everyone…that comes into contact with it, to make sure that it's…going to the right place,…and that it's being delivered to the right person.…When we address a letter, we use a country, state,…city, street, and house number.…With these, we are able to get the letter closer…and closer, to the right person among millions of people.…Everyone has a unique name and address.…
Well, unless you live with…an identical twin with the same name.…The same exists with addresses on the Internet.…Instead of a street address,…addresses on the Internet use numbers.…The use of numbers as addresses…is one of the core concepts of the Internet,…and it is called the Internet Protocol, or IP.…Each device on the Internet has an address…called an IP address.…With IPv4, a current standard, this is a sequence of four,…three-digit numbers separated by a period.…
Each number can be a number from zero to 255,…allowing for over four billion…
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
