Question

a customer needs to use several applications. currently, the computer cannot keep all the necessary applications open at the same time. which of the following components should you consider upgrading?
memory
cpu
hard disk drive
system board

Explanation:

Memory (RAM) stores data that the computer is actively using. If a computer can't keep multiple necessary applications open simultaneously, upgrading memory can help as it allows the computer to hold more data for running programs at once. CPU is for processing, hard - disk drive is for long - term storage, and system board is a connection hub, none of which directly address the issue of running multiple apps simultaneously as effectively as memory.

Answer:

Memory
