Atomic Operations

Q.1: Which type of atomic operation is being used regularly?

Answer:

Large atomic operation is used regularly.

Q.2: By whom parallel processing is implemented?

Answer:

Using atomic operations.

Q.3: Give a reason, why we need atomic operations?

Answer:

To maintain the accuracy of calculated results.

Atomic operations in Operating System are those operations, which execute without interruption of any other process in between their execution phase. They execute at the lowest level and can’t be broken down further. Formally, when an atomic operation is in its executing process, no other process can read, modify, or interrupt that operation’s data.

These types of operations are used very much in parallel processing where the operations are needed to run without being dependent or interrupted by any other process of an OS. These operations are the backbones of modern Operating Systems, which use parallel processing to execute tasks at a much faster speed. Parallel processing is a very popular method for making modern OS much faster. These atomic operations help to implement parallel processing.
