Understanding the Importance of Packets and Protocols in Networking

💡 The internet works by sending digital information in the form of packets using protocols.

🌐 Every device on the internet has a unique IP address, which is used to find and connect with other computers.

🔀 Routing allows information to be sent across the network by hopping between various routers, providing redundancy and scalability.

💡 Data sent over the Internet is broken down into packets, which are tiny units of data.

📦 Packets are labeled with metadata such as the from address and to address, similar to mailing something through the postal service.

🌐 All computers and devices on the Internet agree to set up their packets in the same way, following the Internet Protocol (IP).

📦 IP standardizes the layout of packets with destination and from IP addresses.

🔁 TCP allows for sending multiple packets between two computers and ensures they are put together in the proper order.

🔢 TCP adds a packet number to each packet for tracking the order and reconstructing packets if they arrive out of order.

📦 Packets are used to transmit data across the internet.

🌐 HTTP is a protocol for requesting and receiving web resources.

💻 HTTP requests and responses structure communication between computers.

💡 TCP/IP, DNS, and routing work together to send packets across the Internet.

📦 HTTP packages the information inside packets to ensure understanding.

🌐 The process of viewing a web page involves typing a URL, constructing an HTTP request, and resolving the domain's IP address using DNS.

🔍 The domain name system converts a domain into an IP address.

💡 TCP/IP breaks down HTTP requests into packets and labels them with metadata.

🔄 TCP checks if all packets are received and requests resent if needed.

🔒 TCP ensures all packets are received and requests missing packets to be resent.

💻 Computers and servers use the same protocols to communicate and reconstruct the original message.

🌐 The internet is a packet-switched system that sends data in small blocks called packets.
