Explain read modify write feature.

The Read-Modify-Write (RMW) feature is a common method used in computing, particularly in the context of multi-threading and parallel processing. Here's a step-by-step explanation of how it works:

1. Read: The first step in this process is to read the data from a particular memory location. This data is then stored in a temporary location for processing. This is the 'Read' part of the operation.

2. Modify: Once the data has been read and stored in a temporary location, it can then be modified. This could involve a simple operation such as incrementing the value of the data, or it could involve a more complex operation. The important thing is that the original data is not changed in the memory
