The SYSV checksum, often associated with the System V Release (SYSV) Unix operating system, refers to a checksum algorithm used in the context of shared memory segments and semaphores. More specifically, it is commonly used in System V IPC (Inter-Process Communication) mechanisms to ensure data integrity. In many Unix-like systems, when working with shared memory or message queues, a checksum can validate that the data being accessed has not been corrupted.
