Loss of Data in Main Memory:
- The statement that data gets lost when power is switched off in main memory is correct. Main memory, also known as RAM (Random Access Memory), is a volatile memory type. This means that data stored in RAM is only retained when the computer is powered on. When the power is switched off, the data stored in RAM is lost.
Speed of Main Memory:
- Main memory is indeed faster than secondary memory such as hard drives or solid-state drives but slower than registers. Registers are the fastest type of memory in a computer system, followed by cache memory, and then main memory. Registers are located inside the CPU and are used for storing data that is currently being processed.
Composition of Main Memory:
- Main memory is made up of semiconductors, typically in the form of integrated circuits. These semiconductors are used to store data and program instructions that are actively being used by the CPU. When a computer program is executed, the data and instructions required for that program are loaded into the main memory for quick access by the CPU.
Conclusion:
- Therefore, the correct statement among the given options is that all the statements are correct. The main memory of a computer is volatile, faster than secondary memory but slower than registers, and is composed of semiconductors in the form of integrated circuits.
