Homonym: PTR (Pointer)
PTR, or Pointer Register, is a type of register used in computer architecture to hold memory addresses. It helps the processor locate data in memory efficiently, allowing for faster data retrieval and manipulation. PTRs are essential in various programming languages and systems, enabling effective memory management.
In the context of operating systems, PTRs play a crucial role in managing processes and their memory allocation. They help track where each process's data is stored, ensuring that the CPU can access it quickly. This functionality is vital for maintaining system performance and stability.
