1. ROM (Read-Only Memory) is a type of non-volatile memory that stores data permanently and cannot be easily modified or deleted, while RAM (Random Access Memory) is a type of volatile memory that stores data temporarily and is constantly being read from and written to.
2. ROM is used to store the firmware and essential system files needed for the computer to boot up and operate, while RAM is used to store data and program files that are currently being used by the computer.
3. ROM is typically slower than RAM in terms of access speed, as it is designed for long-term storage and not for quick retrieval of data. RAM, on the other hand, is much faster and allows for quick access to data by the computer's processor.
4. ROM is usually smaller in capacity compared to RAM, as it only needs to store essential system files and firmware. RAM, on the other hand, can have a much larger capacity to accommodate the data and programs being used by the computer.
5. ROM is typically not upgradeable or expandable, as it is usually soldered onto the motherboard or stored in a chip that cannot be easily replaced. RAM, on the other hand, can be easily upgraded or expanded by adding more memory modules to the computer.

ROM (Read-Only Memory)
- Purpose: Stores permanent data that cannot be modified or erased (e.g., firmware, boot instructions)
- Type: Non-volatile
- Access Speed: Slower than RAM
- Characteristics:
- Fixed storage capacity
- Typically used for long-term storage of data that does not change frequently
- Requires special equipment or software to program/update
- Examples: BIOS firmware, operating system image, ROM cartridges (e.g., in gaming consoles)
RAM (Random Access Memory)
- Purpose: Stores temporary data that can be read and modified by the CPU
- Type: Volatile (data is lost when power is removed)
- Access Speed: Faster than ROM
- Characteristics:
- Random access to any memory location
- Capacity can vary from a few MB to several GB
- Provides a fast working space for the CPU to process data and instructions
- Examples:
- System memory (main memory)
- Graphics card memory (VRAM, GDDR)
- Cache memory
Key Differences:
- Mutability: ROM is read-only, while RAM can be read and written to.
- Volatility: ROM is non-volatile, while RAM is volatile.
- Access Speed: RAM is significantly faster than ROM.
- Purpose: ROM stores permanent data, while RAM stores temporary data.
- Examples: ROM: BIOS, OS image; RAM: System memory, VRAM
