Is rom internal memory or external memory?

ROM is memory, a solid-state storage. ROM is also called read-only memory. It can only read out the solid-state semiconductor memory that has stored data in advance. The characteristic of ROM is that it can be written once and read repeatedly.

ROM belongs to memory. ROM is also called read-only memory. It can only read the solid-state semiconductor memory that has stored data in advance. The difference between ROM and RAM is that ROM is characterized by writing once and reading repeatedly; RAM is characterized by random access, and the two are often easily confused.

In a broad sense, memory refers to the three parts of Cache, ROM and RAM. The Cache is now inside the CPU, the ROM is on the motherboard and is used to store the BIOS, and the installed memory refers to It's RAM. Solid-state semiconductor memory that can only read previously stored data.

Mobile phone memory is generally divided into running memory RAM and body storage memory ROM.

Running memory RAM: equivalent to computer memory, used for data exchange and instruction processing. The larger the memory, the faster the running speed. The running memory RAM of mobile phones generally cannot be expanded;

Body storage memory ROM: equivalent to the hard disk of a computer, used to store data, files, and information. The larger the space, the more things can be stored. For example, an extended SD card can be inserted, which is also an expansion of the ROM.

In computers, when the running memory RAM is insufficient, part of the ROM can be called as a cache, but this is generally not possible on mobile phones. When the running memory RAM of the mobile phone is insufficient, the only solution is to clean it up.

In layman’s terms, rom is solid-state storage and ram is dynamic storage. The two biggest differences can be seen literally. The ROM is equivalent to a permanent hard drive. Storing things on it can be used repeatedly and is not easy to lose! RAM is equivalent to the C drive on an Internet cafe computer. Data will be lost due to restarting and other reasons, and it will act as a cache on the phone! As for applications such as qq, they are installed on rom! There is also an SD card that increases the total memory of the phone, but to a certain extent, the SD card is equivalent to a ROM. The former is more flexible to use! By the way, rom and ram are chips that must be installed during mobile phone manufacturing. It is an important component of a mobile phone!
