Q&A

• What are data packets and how do protocols manage their flow in the internet?

  Data packets contain video, sequence numbers, and IP addresses. These packets are routed to devices, reassembled based on sequence numbers, and resent if lost. Protocols manage the flow of data packets in the internet.

• Who manages the complex optical fiber cable network, and how is data transmitted efficiently?

  The complex optical fiber cable network, which is the backbone of the internet, is managed by ICANN for efficient data transmission through packetization.

• How does DNS work and who maintains the global optical fiber cable networks?

  DNS is like a phone book for the internet, translating domain names into IP addresses. Global companies maintain the optical fiber cable networks which are used to transfer data.

• How do domain names and IP addresses work together for accessing websites?

  The internet works through IP addresses, but we use domain names for easier access. Servers store websites and use IP addresses. Domain name requests are resolved through the domain name system (DNS).

• How is the internet connected and how is data stored and transferred?

  The internet is connected by a network of optical fiber cables and data is stored in solid-state devices within data centers. Data is transferred to devices via IP addresses.

• How does data travel from data centers to users?

  Data travels from data centers to users through a complex transmission process. It does not rely on satellites for transmission due to the significant latency caused by distance.

• 00:00 The internet works through data transmission from data centers, but using satellites for transmission causes significant latency. Instead, data is transmitted through a complex system.
• 01:25 The internet is connected by a network of optical fiber cables, data is stored in solid-state devices within data centers, and transferred to devices via IP addresses.
• 03:00 The internet works through IP addresses, but we use domain names for easier access. Servers store websites and use IP addresses, and host headers are used to uniquely identify websites on a server. Giant websites have dedicated infrastructure. Internet service providers assign IP addresses, and domain name requests are resolved through domain name system (DNS).
• 04:25 The internet uses DNS to translate domain names into IP addresses, and data is transferred via optical fiber cables with global companies maintaining these networks.
• 05:52 The internet relies on a complex optical fiber cable network, managed by ICANN, for efficient data transmission through packetization.
• 07:26 Data packets containing video, sequence numbers, and IP addresses are routed to your phone, reassembled based on sequence numbers, and resent if lost. Protocols manage the flow of data packets in the internet.
