🔑Protocols are a set of rules that define how systems communicate with each other.
🌐Different protocols have different purposes, such as HTTP for web communication and UART for hardware communication.
🗒️Protocols can be text-based, like HTTP, or based on binary data, like TCP and UDP.
🔄Some protocols involve a back-and-forth interaction, like establishing connections with TCP.
🔐Understanding protocols is essential for effective communication and exploring the world of hacking.
What is a protocol?
—A protocol is a set of rules that governs how systems communicate with each other.
What are some examples of protocols?
—Examples of protocols include HTTP for web communication, TCP and UDP for network communication, and UART for hardware communication.
Are all protocols text-based?
—No, protocols can be text-based, like HTTP, or based on binary data, like TCP and UDP.
Do all protocols involve back-and-forth interaction?
—No, some protocols, like UART, involve a single message, while others, like TCP, require a back-and-forth interaction to establish connections.
Why is understanding protocols important?
—Understanding protocols is important for effective communication and exploring the world of hacking, as it enables us to interact with systems and identify vulnerabilities.
