This article will explain in detail whether rom in the computer refers to memory or external memory. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Rom is memory, solid-state storage, rom is also known as read-only memory, can only read the data stored in advance of the solid-state semiconducting memory, ROM is characterized by a write, read repeatedly.

ROM belongs to memory, rom is also known as read-only memory, can only read the pre-stored data of the solid-state semiconductor memory. The difference between ROM and RAM is that ROM is characterized by one write and repeated read, while RAM is random access, and the two are often confused.

In a broad sense, internal weight storage refers to three parts: Cache, ROM and RAM, in which Cache is now done in CPU, ROM is on the motherboard, used to store BIOS, installed memory refers to RAM. A solid-state semiconductor memory that can only read pre-stored data.

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

Running memory RAM: equivalent to the computer's memory, used for data exchange, instruction processing, the larger the memory, the faster the running speed, the mobile phone's running memory RAM generally cannot be expanded

Fuselage storage memory ROM: equivalent to the computer's hard disk, used for data, files, data storage, the larger the space, the more things can be stored, such as pluggable expansion SD card, but also the expansion of ROM.

In a computer, when the running memory RAM is insufficient, you can call part of the ROM as the cache, but the mobile phone generally does not. When the mobile phone's running memory RAM is insufficient, the only solution is to clean up.

Generally speaking, rom is solid storage and ram is dynamic storage. The two biggest differences can be seen literally that the rom is the equivalent of a permanent hard drive. Save things on it can be used repeatedly, not easy to lose! Ram is equivalent to the c disk on the computer of the Internet bar. Restart and other reasons will lose data, play the role of cache on the phone! As for qq and other applications are installed on rom! There is also an SD card that increases the total memory of the phone, but to some extent, the SD card is equivalent to rom. The former is more flexible to use! By the way, rom and ram are the chips that must be installed when making mobile phones. It is an important part of a mobile phone!
