ROM or RAM: Which is the phone s running memory?

Running memory is RAM, also called random access, used for cache, the capacity is relatively small, generally 1GB, 2GB, 3GB in this way, ROM is read-only storage, that is, quite used for storage, not for cache, the capacity is generally 16GB, 32GB or larger.

The answer is 100% that RAM-ROM stands for Read-Only Memory, which is a type of solid-state semiconductor memory that can only read out previously stored data. It is characterized by the fact that once the information is stored, it cannot be changed or deleted. It is usually used in electronic or computer systems that do not require frequent changes to the data, and the data does not disappear when the power is turned off.

RAM and random access memory are synonyms that have been combined. RAM -Random Access Memory. Storage that the contents of a storage cell can be removed or deposited as needed, and the speed of access is independent of the location of the storage cell.

This type of memory loses its stored contents when the power is lost.

3-5 circuit principle analysis, basic knowledge of electronic technology, circuit DIY, home appliance repair cases are updated every week. Occasionally, I will share some trivial things about life. Friends who like it can pay attention to learning together and grow together.

RAM is a kind of storage technology, but the principle of the two is different, RAM is random storage, and the data will not be saved when the power is off, while the ROM can still save the original data in the case of power failure. ROM and RAM both refer to semiconductor memory. The original meaning of the tease was:

ROM stands for Read Only Memory, which means that this kind of memory can only be read and not written. Whereas, RAM is an abbreviation for Random Access Memory. The origin of the term is due to the fact that early computers used magnetic drums as memory, and magnetic drums and magnetic tapes were typical sequential read-write devices.

RAM can be read and written randomly.

2.In layman's terms, for example, in the computer, we all know that there is memory and hard disk, in fact, memory is a kind of RAM technology, and ROM is similar to hard disk technology, both are memory, but the speed of RAM is much higher than the speed of ROM, in the daily operation of the computer, many programs will temporarily run the program commands, stored in memory, but once shut down or power failure, the original temporary storage of program information in the memory will be emptied, that is, the memory can only temporarily store things, It can't be stored for a long time, while the ROM can be stored, and even after the power is off, you can find the previously stored files, which is the hard disk.

3.In the mobile phone, RAM refers to the memory of the mobile phone, which belongs to the internal memory of the mobile phone, belongs to random storage, and the speed is higher than that of the ROM, which plays an important role in the configuration performance of the mobile phone.

It belongs to external storage, for example, we can often buy SD cards and put them in the mobile phone, which is the mobile phone ROM, and the mobile phone ROM is what we usually call the memory card, which can also be simply understood as the mobile phone hard disk. It is used to store mobile phone system files, **, movies, etc., and will not lose data with power failure, and the larger the ROM, the more data will be stored.

What is the meaning of RAM and ROM in a mobile phone? How to tell the difference? Let's take a look.

01 RAM is what we often call running memory. Compared to a computer, it is like memory in a computer.

02 ROM is the phone's storage memory. Compared to a computer, it is like a hard disk in a computer.

03 The obvious difference is that RAM is smaller, generally 4G, 6G or 8G capacity.

The ROM is relatively large, 32G, 64G, 128G is the current capacity commonly used in mobile phones.
