Origins of LAN
The Birth of Networking: Early Developments and Protocols 🏢🌐
The concept of local area networking traces back to the 1960s and 1970s, a time when researchers and technologists explored ways to interconnect computing devices for collaborative purposes. Early LAN implementations focused on proprietary protocols and hardware solutions tailored to specific computing environments.
Ethernet Emergence
Ethernet Era: Xerox PARC and the Birth of a Standard 🔄🔌
In the early 1970s, researchers at Xerox PARC (Palo Alto Research Center) developed Ethernet, a groundbreaking networking technology that laid the groundwork for modern LANs. Ethernet's standardized protocols, such as CSMA/CD (Carrier Sense Multiple Access with Collision Detection), revolutionized data transmission over shared media.
IEEE 802 Standards
Standardization Drive: IEEE 802 Family of LAN Standards 📘🌐
The Institute of Electrical and Electronics Engineers (IEEE) played a pivotal role in standardizing LAN technologies through the development of the IEEE 802 family of standards. IEEE 802.3, commonly known as Ethernet, became the de facto standard for wired LANs, while IEEE 802.11 defined wireless LAN (Wi-Fi) standards.
