What is the difference between buffered and unbuffered channels in Go?
- Buffered channels allow a fixed number of values to be queued before blocking, whereas unbuffered channels block until both sender and receiver are ready.
- Buffered channels allow concurrent access from multiple goroutines, while unbuffered channels are limited to a single goroutine.
- Buffered channels are synchronous, while unbuffered channels are asynchronous.
- Buffered channels have a smaller memory footprint compared to unbuffered channels.
Buffered channels in Go have a fixed size buffer, allowing a certain number of elements to be stored before blocking. On the other hand, unbuffered channels have no capacity for queuing elements, meaning that sends and receives on an unbuffered channel must synchronize immediately. Understanding this difference is crucial for managing communication and synchronization between goroutines efficiently.
