📚 Quick Study Guide

  • 🌐 TCP/IP (Transmission Control Protocol/Internet Protocol): The foundational protocol suite for the internet. It defines how data is broken down into packets, addressed, transmitted, routed, and received.
  • 📦 TCP: Provides reliable, ordered, and error-checked delivery of a stream of bytes between applications running on hosts communicating via an IP network. Uses a three-way handshake (SYN, SYN-ACK, ACK) to establish a connection.
  • 📡 IP: Handles the addressing and routing of packets between networks. Each device on a network has a unique IP address.
  • 🔗 HTTP (Hypertext Transfer Protocol): The foundation of data communication for the World Wide Web. It defines how messages are formatted and transmitted, and what actions web servers and browsers should take in response to various commands.
  • 🔒 HTTPS (Hypertext Transfer Protocol Secure): The secure version of HTTP. It encrypts HTTP communications using SSL/TLS, providing secure identification of a web server.
  • 🔑 SSL/TLS (Secure Sockets Layer/Transport Layer Security): Cryptographic protocols that provide secure communication over a network. They encrypt the connection between a client and a server, protecting sensitive data like passwords and credit card numbers.
  • 🔢 Port Numbers: HTTP typically uses port 80, while HTTPS uses port 443. These ports are used to identify specific processes or services running on a server.
  • 🤝 Three-way Handshake: TCP uses a three-way handshake to establish a reliable connection:
    1. SYN (Synchronize) - The client sends a SYN packet to the server to initiate the connection.
    2. SYN-ACK (Synchronize-Acknowledge) - The server responds with a SYN-ACK packet to acknowledge the client's SYN and indicate its willingness to establish a connection.
    3. ACK (Acknowledge) - The client sends an ACK packet to acknowledge the server's SYN-ACK, completing the handshake.
