Study Notes
ROM Chips
- ROM chips store instructions permanently.
- Data on ROM chips is non-volatile.
- ROM data is either unchangeable or requires special operations to change.
- Different types of ROM chips exist:
- ROM - cannot be reprogrammed
- PROM - can be programmed once
- EPROM - can be erased and reprogrammed multiple times
- EEPROM - can be reprogrammed without removing from motherboard, specific portion of data can be change without erasing the whole chip.
RAM Chips
- RAM is volatile memory; data is lost when power is turned off.
- RAM is used in computers, tablets, smartphones, and printers.
- RAM is accessed randomly.
- RAM is stored on Dual In-line Memory Modules (DIMMs).
- RAM speed is measured in MHz.
- RAM capacity is measured in GB.
- The amount of RAM a device has affects processing speed.
- Restarting a computer can fix certain issues because applications are loaded into RAM upon startup.
