# What is ALOHA?

What is ALOHA?

## Answers

### Answer by Hitesh Vohra

- **ALOHA** is a multiple-access protocol that allows data to be transmitted via a shared network channel. It uses the open systems interconnection (OSI) model's medium access control sublayer ([**MAC**](https://answers.mindstick.com/qa/95841/how-will-it-differ-in-performance-if-i-install-windows-on-a-mac-laptop) sublayer). Several data streams from several nodes are exchanged across a multi-point transmission channel using this protocol.
- Each node or station in ALOHA transmits a frame regardless of whether the transmission channel is idle or busy. The frames will be successfully transferred if the channel is idle. If two frames try to occupy the channel at the same time, they will collide and the frames will be destroyed.
- These stations may elect to repeatedly retransmit the faulty frames until successful transmission is achieved.
