More understanding about phone's memory - RAM and ROM

Phone's memory

Phone's memory includes RAM and ROM. RAM equals the memory (or memory bar) of the computer, while ROM is the device's internal storage, equaling the hard disk of the computer.

The bigger the RAM, the more software the phone runs smoothly; While the bigger the ROM, the more data it can store. Usually, a phone with big RAM is not easy to get stuck.

The ROM on smartphones

ROM (Read Only Memory) is a form of data storage. This type of memory keeps the saved data even if the device power is off. The word Read-only identifies it as "read-only memory", since the reprogramming process is generally infrequent, comparatively slow, and often does not permit random access writes to individual memory locations. It equals a hard disk in a computer, storing various of files, including videos, songs, photos, and system software, etc. At present, most smartphones are equipped with 16GB, 32GB, 64GB, or even 128GB, 256GB large ROM. But we have to pay attention that in phones the ROM is not described with ROM but with storage.

The RAM on smartphones

RAM (Random Access Memory) is the memory where the software resides while it is running along with the data it is using. RAM is used by both OS and application software.

RAM is very fast but volatile, meaning that all information is lost when electric power is cut off, allowing data to be read or written irrespective of the physical location of data inside the memory. Devices with more RAM can run more complex software and multiple applications at the same time.
