The correct answer is: B. random-access memory (RAM)
RAM is a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is typically used to store data and instructions that are being actively used by the computer.
Sequential-access memory (SAM) is a type of computer memory that can only be accessed in a sequential order. This means that to access a particular byte of memory, the computer must first access all of the bytes that come before it. SAM is typically used to store data that does not need to be accessed quickly, such as data that is being archived or data that is being used for backup purposes.
Secondary memory is a type of computer memory that is not directly accessible by the CPU. Secondary memory is typically used to store data that is not currently being used by the computer, such as data that is being used for backup purposes or data that is being archived.
Mass storage is a general term for any type of storage device that can store large amounts of data. Mass storage devices typically include hard drives, optical drives, and solid-state drives.
