Types in π-calculus

In π-calculus, "types" are like categories that specify what kind of data or communication a process can handle, ensuring correctness and safety. Think of them as labels that define whether a channel (communication link) transmits integers, strings, or other data types. By assigning types, systems prevent errors like sending incompatible data, facilitating reliable interaction between processes. In essence, types in π-calculus help organize and verify complex interactions, much like rules in programming languages, making sure that the communication behaves as intended without unexpected issues.
