Detailed explanation-1: -Answer: The contents of (d) memory are lost when the computer turns off. Explanation: Memory refers to the internal storage of a computer where data and instructions are temporarily stored for quick access by the CPU.
Detailed explanation-2: -ROM stands for READ ONLY MEMORY and is non-volatile memory. When the computer is shut down the data remains stored. If a computer doesn’t have enough RAM is can use a portion of its HARD DRIVE as memory, this is known as VIRTUAL memory.
Detailed explanation-3: -Nonvolatile memory is the memory that can keep the information even when it is powered off. In other words, nonvolatile memory requires power while storing the data; however, once the data is stored, the nonvolatile memory technologies do not require power to maintain the data stored.
Detailed explanation-4: -Data is represented on modern storage media using the binary numeral system. All data stored on storage media – whether that’s hard disk drives (HDDs), solid state drives (SSDs), external hard drives, USB flash drives, SD cards etc – can be converted to a string of bits, otherwise known as binary digits.
