- What are the differences between read-only memory (ROM) and random-access memory (RAM), the two types of computer memory?arrow_forwardHow is virtual memory different from physical memory, and why is it important in modern computing systems?arrow_forwardData in memory can be accessed in two ways: sequentially or directly. Why is it beneficial to have instant access on today's most widely used devices? If a device only permits direct access through sequential access, how can we make changes to data that has already been written there?arrow_forward

What are the benefits of direct access, and why do today's most crucial technologies rely on it? How can information stored in a device that only allows for sequential access be converted so that it may be accessed by a device that only allows for direct access?arrow_forward
