Data stored in ROM is not lost when a computer is switched off since the memory is volatile.

-ROM is used to store data that won't be altered many times or programs that are repeatedly opened and used (E.g the bootstrap program is stored in ROM)
-ROM is also used in many embedded systems.

1) Simplest form of ROM: data/ programs installed during the manufacturing process.
2) Programmable ROM (PROM): A system builder receives chips from the chip manufacturer. The program or data is loaded into the chips by the system builder. As a result, the system developer can test a few samples of the programmable chip before committing to programming the entire batch. Similar to the simplest sort of ROM, once installed, the program or data cannot be altered.
3) Erasable PROM (EPROM): It is possible to install new data or a new program after erasing the existing data or program (using UV light). However, in order to perform this reprogramming, the chip must typically be taken out of the circuit.
4) Electrically Erasable PROM (EEPROM): Similar to EPROM, but with the ability to delete existing data using an electrical signal. The primary benefit of this is that the chip can stay in the circuit while the contents are modified. The chip is still utilised as read-only, though.]]> 2023-09-26 07:43:12 UTC https://padlet.com/awafat2025/derqflxe2bxpdyjk/wish/2720728049 What is RAM? eisoma2025 https://padlet.com/awafat2025/derqflxe2bxpdyjk/wish/2720735632 Random Access Memory (RAM) is used to store files in use and machine code, RAM is a temporary storage, this means that it closes when the computer closes and files aren't stored when they're not in use.]]> 2023-09-26 07:48:24 UTC https://padlet.com/awafat2025/derqflxe2bxpdyjk/wish/2720735632
