It is used to store data’s and instructions. It is considered as a random access since it allows the stored instructions to be accessed in any order. There is another term called SAM- serial access memory which allows only sequential access of data’s and therefore it is considered as opposite to RAM.
Random conveys the idea that any number of data can be returned in a stable time despite of its physical location. It is usually linked with volatile types of memory, where the data is lost when the power is switched off. Some types of RAM have circuitry which helps in detecting faults in the stored data.
Swapping is an operation related to RAM which is performed when the system becomes low on RAM when application process is running. It is an additional working memory. Thrashing is another term related to RAM and it refers to excessive use of swapping.
