The 802 series is a family of IEEE standards for local area networks (LANs) and metropolitan area networks (MANs). These standards are developed by the IEEE 802 LAN/MAN Standards Committee and are widely used in various networking applications. The series is named after the year 1980, when the first standards were developed, and the number 2, which is the second in a series of standards.

The 802 series includes several subcommittees, each focusing on a specific aspect of networking. The most well-known subcommittees are 802.1, which deals with network management and higher-layer protocols, and 802.3, which specifies the Ethernet standard for wired LANs. Other subcommittees include 802.11 for wireless LANs, 802.15 for personal area networks, and 802.16 for broadband wireless access.

The 802 series standards are designed to ensure interoperability between different networking devices and systems. They define the physical and data link layers of the OSI model, including protocols, frame formats, and signaling methods. By adhering to these standards, manufacturers can produce compatible products that can work together seamlessly.

The 802 series has significantly influenced the development of modern networking technologies. The Ethernet standard, for example, has become the dominant LAN technology, powering the vast majority of wired networks worldwide. Similarly, the 802.11 standards have enabled the widespread adoption of Wi-Fi, providing wireless connectivity for millions of devices.

In summary, the 802 series is a crucial set of standards that have shaped the landscape of modern networking. By defining key aspects of LAN and MAN technologies, these standards have facilitated the development of interoperable and efficient networking solutions.
