What is the purpose of TCP?

In the digital age, where global communication is essential, the Transmission Control Protocol (TCP) plays a crucial role in ensuring seamless data transmission over the Internet. It is a foundational protocol that forms the backbone of modern networking, enabling devices across the world to exchange information reliably, efficiently, and securely. So, let’s break down its inner workings, significance, and impact on our daily online experiences.

The Basics of TCP

TCP (Transmission Control Protocol) is one of the core protocols of the Internet Protocol Suite (TCP/IP), which controls how data packets are transmitted and received across networks. It operates at the transport layer of the OSI model and provides a reliable, connection-oriented communication mechanism. Unlike its counterpart, the User Datagram Protocol (UDP), which offers minimal error-checking and no guaranteed delivery, TCP focuses on ensuring that data is delivered accurately and in the correct order.

DNSSEC explained for beginners

Introduce to DNSSEC

In order to supply cryptographic authentication to DNS data, a set of security techniques known as DNSSEC (Domain Name System Security Extensions) was built. It verifies and validates the accuracy of DNS data, so you know they haven’t been changed.

Because it validates each DNS query step, network experts frequently refer to it as a chain of trust.

What is IPv4 used for?

What exactly is IPv4?

In the early 1980s, the concept of IPv4 address type was created. Even if a new version of IP addresses is available, IPv4 remains the most popular among internet users.

Internet Protocol version 4 is the foundational technology for connecting all devices to the Internet. A numerical IP address, such as 45.17.98.65, is assigned to a gadget when it establishes a connection. A data packet comprising both devices’ IP addresses must be transferred over the network to transfer data via the Internet from one device to another.
