Aloha

Aloha, in the context of computer networking, is a simple communication protocol used for transmitting data between devices over a shared channel, such as radio or wired connections. Devices send data whenever they want, but if two devices transmit simultaneously, a collision occurs, causing data loss. To handle this, devices wait for random periods before retrying, reducing the chance of repeated collisions. Aloha's design is straightforward, making it suitable for low-traffic situations. It laid the groundwork for more advanced network methods and was essential in early wireless communication development.
