!!! Overview [{$pagename}] for our purposes is about the [{$pagename}] [Network] [Protocol] The version of the protocol (now called "Pure ALOHA", and the one implemented in [ALOHAnet|Wikipedia:ALOHAnet|target='_blank']) was quite simple: * If you have data to send, send the data * If, while you are transmitting data, you receive any data from another station, there has been a message collision. All transmitting stations will need to try resending "later". Note that the first step implies that Pure [{$pagename}] does not check whether the channel is busy before transmitting. Since collisions can occur and data may have to be sent again, [{$pagename}] cannot use 100% of the capacity of the [communications] [Channel]. How long a station waits until it transmits, and the likelihood a collision occurs are interrelated, and both affect how efficiently the channel can be used. This means that the concept of "transmit later" is a critical aspect: the quality of the backoff scheme chosen significantly influences the efficiency of the [protocol], the ultimate channel capacity, and the predictability of its behavior. To assess Pure [{$pagename}], there is a need to predict its throughput, the rate of (successful) transmission of [Frames]. !!
