What is Bonjour?

Bonjour Service provides a general method to discover services on a local area network. The software is widely used throughout Mac OS and Windows for iOS devices, and allows users to set up a network without any configuration. It is used to find printers and file-sharing servers. iTunes uses Bonjour to find shared music, iPhoto to find shared photos. Bonjour for Windows and AirPort Base Stations may be configured to use Wide Area Bonjour which allows for wide area service discovery via a configured DNS server. Bonjour, also known as zero-configuration networking, enables automatic discovery of devices and services on a local network using industry standard IP protocols. Bonjour makes it easy to discover, publish, and resolve network services with a sophisticated, yet easy-to-use, programming interface that is accessible from Cocoa, Ruby, Python, and other languages.

Bonjour appears to create conflicts with McAfee. With both automatically running with startup, it takes significantly longer for my computer to log onto WiFi. After logging on to WiFi, it takes longer to connect to the internet. Disabling either eliminates both delays.

Bonjour is Apple's implementation of Zero configuration networking (Zeroconf), a group of technologies that includes service discovery, address assignment, and host resolution. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records.
