FidoNet is a worldwide computer network that is used for communication between bulletin board systems (BBSes). It was founded in 1984 by Tom Jennings and has played a significant role in the development of online communities and electronic communication.

History

FidoNet was created to allow BBSes to exchange messages and files with each other. The network was named after Jennings' dog, Fido. Initially, it was a small network of BBSes in the United States, but it quickly grew to include systems from around the world. By the late 1980s, FidoNet had become one of the largest computer networks in existence.

Structure

FidoNet is organized into a hierarchical structure. The network is divided into zones, regions, nets, and nodes. Each zone represents a large geographic area, such as a continent. Zones are further divided into regions, which are then divided into nets. Each net contains multiple nodes, which are individual BBSes.

Zones

There are six primary zones in FidoNet:

• Zone 1: North America
• Zone 2: Europe
• Zone 3: Oceania
• Zone 4: Latin America
• Zone 5: Africa
• Zone 6: Asia

Nodes

Nodes are the individual BBSes that make up the network. Each node has a unique address, which is used to route messages and files. The address format is Zone:Net/Node, for example, 1:123/456.

Technology

FidoNet uses a store-and-forward system to transfer messages and files between nodes. Messages are bundled into packets and sent to a central hub, which then forwards them to their destination. This process can take several hours or even days, depending on the distance between nodes and the speed of the network.

FidoNet Protocol

The FidoNet protocol, also known as FTN (FidoNet Technology Network), defines the standards for communication between nodes. It includes specifications for message formats, file transfers, and error handling.

Echomail and Netmail

FidoNet supports two main types of messages: Echomail and Netmail.

• Echomail is a public message system similar to Usenet newsgroups. Messages are distributed to all nodes that subscribe to a particular echo.
• Netmail is a private message system that allows users to send messages directly to other users on the network.

Decline and Legacy

With the rise of the Internet in the 1990s, the popularity of FidoNet began to decline. Many BBSes transitioned to using Internet protocols such as TCP/IP and SMTP for communication. However, FidoNet still exists today and is used by a small but dedicated community of enthusiasts.
