ROM and RAM Basics
ROM (Read-Only Memory)
ROM is a type of memory that cannot be modified once it is programmed.
It is used to store essential system software, such as the operating system, device drivers, and firmware.
ROM is typically programmed during the manufacturing process, before the system is shipped.
RAM (Random Access Memory)
RAM is a type of memory that can be modified and erased.
It is used to store temporary data and instructions that are being processed by the processor.
RAM is divided into smaller units called memory cells or bytes. Each byte is stored in a unique location.
Differences between ROM and RAM:
| Feature | ROM | RAM |
|---|---|---|
| Modularity | Read-only | Read-write |
| Programming | During manufacturing | After system boot |
| Contents | Essential system software | Temporary data and instructions |
| Size | Typically larger | Smaller |
| Access time | Faster | Slower |
| Cost | More expensive | Less expensive |
