ROM (Read-Only Memory) is a type of non-volatile memory that is used in computers and other electronic devices to store data that is permanently written during the manufacturing process. Here are some characteristics of ROM:
1. Non-volatile: ROM retains its data even when the power is turned off, making it a non-volatile form of memory.
2. Read-only: The data stored in ROM cannot be easily modified or deleted, hence the name "read-only memory". This makes ROM ideal for storing firmware and other essential system data that should not be changed.
3. Permanent: The data stored in ROM is permanent and cannot be easily altered or erased. This makes ROM suitable for storing critical system information that needs to be preserved.
4. Faster access: ROM typically has faster access times compared to other types of storage, such as hard drives or flash memory. This allows the system to quickly access important data stored in ROM.
5. Limited capacity: ROM typically has a fixed capacity that is determined during the manufacturing process. This means that the amount of data that can be stored in ROM is limited and cannot be expanded or upgraded.
6. Different types: There are different types of ROM, such as Mask ROM, PROM (Programmable ROM), EPROM (Erasable Programmable ROM), and EEPROM (Electrically Erasable Programmable ROM), each with its own characteristics and uses.
Overall, ROM is a reliable and secure form of memory that is used to store essential system data that needs to be preserved and accessed quickly.

Characteristics of Read-Only Memory (ROM):
1. Non-Volatility:
- Data stored in ROM remains intact even when power is disconnected.
2. Read-Only:
- Data can only be read, not modified. ROM chips are programmed during manufacturing or through special programming devices.
3. Durability:
- ROM is highly reliable and can withstand extreme temperatures, vibrations, and radiation.
4. Fast Access:
- Access to data in ROM is fast because the data is stored in a physical address and does not require any decoding or translation.
5. Limited Capacity:
- ROM has a limited storage capacity compared to other memory types like RAM.
6. Low Power Consumption:
- ROM consumes less power because it only requires power during read operations.
7. Application-Specific:
- Custom ROM chips can be designed for specific applications, where the software code is embedded into the chip.
8. Permanent Storage:
- Data stored in ROM is permanently written and cannot be erased or overwritten by the user.
9. Types:
- Masked ROM (MROM): Permanently programmed during manufacturing, offering the highest reliability.
- Programmable ROM (PROM): Can be programmed once using a special device.
- Erasable Programmable ROM (EPROM): Can be erased by exposure to ultraviolet light and reprogrammed.
- Electrically Erasable Programmable ROM (EEPROM): Can be erased and reprogrammed using electrical signals.
10. Applications:
- Operating systems, bootloader code
- Firmware for microcontrollers and embedded systems
- Storage of configuration data and look-up tables
