Join Doug Winnie for an in-depth discussion in this video Routers and directing requests, part of Computer Science Principles: The Internet.
- Routers are the signposts that packets use to travel…across the Internet and over private networks…within an organization.…Using the header information in data packets,…routers read the information in the header to direct…packets to go to the right location.…In your home, you might have a router that is connected to…your home Internet Service Provider.…When your computer sends out a request for information…or is sending packets of information to another computer,…the first place the request goes is the router.…
The router looks at the information in the header…and sees where it needs to send the information.…In a home network, that could be one of two places.…It could be something that is sent out to the Internet…to connect to another computer or it could be…to another computer or device on your own home network.…When you have a home network, all of your devices…including your computers, tablets, phones, game consoles,…and even smart devices like light bulbs, wireless speaker…systems, and more, are all connected to your router.…
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
