👉 Passback is a system in computer science that allows for the re-use of memory addresses. It is often used to optimize data access by avoiding direct copying and instead using indirect addressing, which can reduce the overhead associated with direct memory allocation and deallocation. In other words, it allows for the reuse of an address when multiple copies are needed, rather than creating new copies every time they're needed. This is particularly useful in scenarios where a large amount of data needs to be accessed frequently or in parallel
