Network: The 8 most common protocols

ChatGPT The rules and conventions governing communication between devices in a computer network constitute network protocols. These protocols play a crucial role in the efficient and secure transmission of data, from sending emails to web browsing. Here we will analyze eight of the most common protocols in modern networks.

TCP/IP (protocolo de control de transmisión/protocolo de internet)

TCP/IP, essential for the Internet, is divided into two parts: TCP, which ensures the sequential and error-free delivery of data, and IP, responsible for addressing and routing packets. This is the foundation that enables communication between devices on the network.

HTTP (protocolo de transferencia de hipertexto)

HTTP is the protocol used to request and display web resources, such as pages and multimedia files, in a browser. It has evolved over time, giving rise to HTTPS (Secure HTTP), which employs SSL/TLS encryption to protect data privacy.

HTTPS (protocolo de transferencia de hipertexto seguro)

HTTPS, the secure variant of HTTP, uses SSL/TLS to encrypt data between the browser and the web server, providing an extra layer of security crucial for sensitive data such as passwords and credit card details.

FTP (protocolo de transferencia de archivos)

FTP facilitates the transfer of files between systems on a network, allowing users to upload and download files from remote servers, although it does not encrypt data during transfer.

SMTP (protocolo simple de transferencia de correo)

SMTP is the standard for sending emails, defining how messages are transmitted and received between mail servers, ensuring reliable delivery of messages over the Internet.

POP3 (protocolo de oficina de correos 3)

POP3 allows mail clients to retrieve messages from a remote server for offline reading, lacking some advanced synchronization features.

IMAP (protocolo de acceso a mensajes de internet)

Unlike POP3, IMAP allows users to organize and manipulate messages on the server, facilitating access from multiple devices.

DHCP (protocolo de configuración dinámica de hosts)

DHCP dynamically assigns IP addresses to devices on the network, simplifying administration by eliminating the need for manual configuration.

In summary, these eight protocols perform essential functions in modern networks, contributing to a secure and efficient experience for users worldwide.
