Join Doug Winnie for an in-depth discussion in this video Remembering requests with cookies, part of Computer Science Principles: The Internet.
- Each time you open the browser and open a web page,…it is a unique request, as if you've…never visited the website before.…Many sites require that you log on to an account,…or there might be some configuration settings or reminders…that you have turned on or off with various websites.…When you make a new request…after you shut down the web browser,…all those things the browser remembers are forgotten.…The time that you're on a site is called a session.…
As you do things during that session,…there are things you can do to configure the site.…But when the browser is shut down,…the session is over and the information is lost.…Browser cookies aren't filled with chocolate chips,…but they do remember the bits about your browser sessions…to make it easier to work with various websites.…For instance, if you're on a site…and you decide to log in, the browser…asks for your user name and password.…When that is entered, the site tells the browser…that it can save the user name as a cookie.…
Why is it called a cookie?…Well, think of a fortune cookie.…
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
