Experienced Software Engineer with over a decade of expertise spanning from programming languages to the Linux kernel. Passionate about exploring and sharing knowledge of the Linux ecosystem.
Ethernet is the world’s most widely used LAN technology, implemented in nearly 80% of LANs. It uses a bus topology and was developed at Xerox’s Palo Alto Research Center in the early 1970s. Intel, Digital and Xerox cooperated to devise a production standard, which is informally called DIX

The OSI (Open Systems Interconnection) Reference Model is a seven-layer framework developed by the ISO in the late 1970s. It standardizes telecommunication and computing functions, enabling diverse networking protocols to communicate seamlessly. Understanding the OSI model is essential for network engineers and IT professionals, as it forms the basis of

Half-duplex Communication Traditionally, in a half-duplex system, communication between two devices is possible, but only one device can transmit data at a time while the other listens, similar to how a two-way radio (like a walkie-talkie) works. The HTTPS protocol operates as a half-duplex protocol. HTTPS (HyperText Transfer Protocol Secure)
