- It can be thought of as a global highway that connects computers across the world.
- The World Wide Web (WWW) is like the traffic on this highway, including video, music, downloading, and instant messaging, etc.
- The core of the internet comprises powerful computers called routers.
- Routers are connected to each other and other networks.
- Institutions often have direct internet access via their own servers.
- Users often access the internet through Internet Service Providers (ISPs).
- Data is divided into smaller pieces—packets—for efficient transmission.
- Packet switching is the method used to transmit data.
- Internet bandwidth indicates the data transmission speed per second.
- The internet helps people perform various tasks and run new applications.
