Practical Cyber Hacking Skills for Beginners - TCP versus UDP

The video tutorial explains the two main protocols for data transmission over the Internet: TCP and UDP. TCP, or Transmission Control Protocol, is connection-oriented and ensures error checking and guaranteed delivery of data packets. It is used in applications like web browsing, file transfers, and emails. UDP, or User Datagram Protocol, is connectionless and does not guarantee delivery, making it suitable for real-time applications like video conferencing, live broadcasts, and online gaming. The tutorial also discusses how these protocols are used in practice, with browsers using UDP for DNS resolution and TCP for retrieving website content.
