Final answer:
The process of comparing bits written to a memory module to what is later read from the module detects and corrects errors in a single bit of the byte.
Step-by-step explanation:
The process of comparing bits written to a memory module to what is later read from the module helps to detect and correct errors in a single bit of the byte. This process is known as error detection and correction. It ensures that the data written to the memory module is the same as the data read from it, making the memory system more reliable.
