Answer:
synchronization
Step-by-step explanation:
Read/write circuitry makes use of synchronization data to compensate for minor variations in rotation speed and other factors that might disturb the precise timing needed for reliable reading and writing.
Synchronization can be defined as the operation or activity of two or more things at the same time or rate.
An example of synchronisation, if multiple threads try to write within a same file then they may corrupt the data because one of the threads can override data or while one thread is opening the same file at the same time another thread might be closing the same file.
