Answer:
1. Volatility
2. Read/Write Access
3. Speed
4. Use
5. Erasability
Step-by-step explanation:
1. Volatility
RAM is volatile memory, which means it loses its data when the computer is powered off or restarted. It is used for temporary data storage while the computer is running.ROM is non-volatile memory, and its data is retained even when the computer is turned off. It contains permanent data, such as firmware and instructions that don't change.
2. Read/Write Access
RAM is read-write memory, allowing the computer's CPU to both read from and write to it. It is used for running programs and storing data temporarily.
ROM is typically read-only memory, meaning it can be read by the computer but not written to by standard processes. It contains data that is "burned" into the memory during manufacturing.
3. Speed
RAM is much faster than ROM. It provides quick access to data, allowing the CPU to retrieve and modify information rapidly, making it suitable for active computing tasks.
ROM has slower access times compared to RAM because it's primarily used for storing firmware and data that doesn't need to change frequently.
4. Use
RAM is used for storing data and program code that is actively being processed by the computer's CPU. It serves as the main memory for running applications and the operating system.
ROM is used for storing permanent instructions, firmware, and software required for the initial booting of the computer. It typically contains the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware.
5. Erasability
RAM is easily erasable and rewritable. Data in RAM is volatile and changes dynamically as programs run, and it can be overwritten with new information.
ROM is usually not erasable or rewritable by standard user processes. Its contents are fixed during manufacturing, and it's meant to be permanent.
