Adding broadband to Macs used to be a hit-and-miss affair in the 1990s before ethernet and WiFi became standard features during the second Steve Jobs era.
Mac users have had networking since 1984 using Apple’s 230.4 Kbps LocalTalk hardware and AppleTalk protocol. However, there was an older networking standard with roots at Xerox PARC (which also inspired the Mac’s look and feel) known as ethernet that was destined to become the networking standard.
