What is Aloha?

ALOHAnet, also known as the ALOHA system, was a pioneering computer networking system developed at the University of Hawaii in the late 1960s. It used a novel method of medium access control known as ALOHA, which allowed multiple stations to transmit data over a shared communication channel without prior coordination. If a collision occurred, the stations would retransmit their data after a random delay. While simple, it demonstrated the feasibility of packet-based radio communication and laid the groundwork for later protocols like Ethernet and Wi-Fi. Aloha protocols are still used in some satellite communication systems.
