What is the computer's primary working memory, in which program instructions and data are stored so that they can be accessed directly by the cpu via the processor's high-speed external data bus?

The correct answer to the following question will be "Random Access Memory".

Explanation:

Random-access memory is a form of storage that can be read and modified in any sequence that is typically used to store working data and compiled code. This feature allows data objects to be stored and updated at almost the same time, regardless of the specific location of the information within the array.It is the primary operating memory of the computer where the program directions and information are collected so that they could be accessed freely by the CPU through the elevated-speed data bus processor.

Therefore, RAM is the right answer.
