What is the use of ROM and RAM for Android phones

Immodestly, the above is inaccurate for the ROM. RAM is running memory, there is no problem, it is equivalent to a memory module, it is good to be big. The ROM is also big, but the impact on speed is different from RAM, and the reason why it's big is good is because the program is installed in the ROM and runs faster.

The ROM should be equivalent to the hard disk of the computer, not just the C disk, and the memory card is equivalent to the USB flash drive on the computer. Programs installed on the phone's memory card are slower to respond to due to the fact that they are to read the card than those installed in the phone's internal memory (ROM). If all the programs are installed on the memory card, it doesn't make sense for the ROM to be large.

ROM is the phone's own memory,On Android phones,There are a lot of software that can only be installed on the built-in storage,Even if the software is installed in the card,The cache and storage files inside will be installed in the built-in storage,So that the built-in memory will slowly decrease,So for Android,ROM is still as big as possible,Now most of the mainstream ones are512M,But it's best to choose 2G,Moto's defy is。 RAM is mobile phone storage,If the memory is too small,Then it will be easy to get stuck when you open multiple software,Software and games are occupied by memory,Suppose an open software accounts for 50M of memory,Then if the RAM that comes with it is 128M,Then open two software will occupy a lot of memory and be very stuck,Sometimes it will be easy to crash,So it's better to have a larger memory。 The above is a bit popular, but that's the truth, I hope it will help you!

RAM is the running memory of the mobile phone, just like the number of lanes on the highway, the more lanes, the more cars that run at the same time, and the larger the RAM, the faster the mobile phone runs, and the better the performance of the mobile phone. It's the same as the memory on your computer. Generally speaking, the RAM of today's mobile phones is starting to get bigger and bigger, generally between 1G-8G.

The range of ROMs is basically between 1G and 32G now, and of course there are outside this parameter, but they are rare.

From the above analysis, it can be seen that whether it is RAM or ROM, the bigger the better. But for ROM,Generally and the mobile phone comes with the memory card class level also has a certain relationship,The higher the class level,The better the performance of the memory card,Today's memory card capacity can basically be explained is the ROM capacity!

In layman's terms, ROM is by default, the software you install will go there, and the ROM is large, and the more software you can install. RAM, the running memory, is the equivalent of a computer's memory module, which determines the number of apps you can open at the same time. The more RAM you have, the more software you can run at the same time!

You understand!

Hello. ROM is equivalent to C disk,Naturally, the bigger the better,In addition to putting firmware,The software is also installed here by default,If it's big, it will run more smoothly。

RAM is used to run programs, and if ROM only indirectly affects speed, then this is directly related to the health of the phone.

If you want to run new games and good-looking special effects, it is best to use 512ram512rom, of which RAM plays a decisive role.

RAM and ROM are both memory, which belong to semiconductor memory, and are divided into RAM and ROM in terms of read and write data functions.

1. RAM means random memory, that is, it can read and write data to the memory at any time under normal working conditions. According to the working principle of the memory cell, RAM can be divided into static memory (SRAM) and dynamic memory (DRAM). Features of RAM::

readable and writable; When the memory is powered off, the data stored inside is lost.

2. ROM means read-only memory. Such memory can only be read and cannot be read and written at any time like RAM. It only allows one write opportunity after it has been produced, and the data cannot be changed once it is written.

Another feature of the memory is that the data inside the memory is not lost after the power is off, and it can be stored for hundreds of years. To sum up, RAM refers to the memory of the mobile phone, and ROM refers to the memory that stores the firmware of the mobile phone, such as the operating system of the mobile phone, some applications such as games, etc.

ROM and RAM are both 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 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.

RAM can be read and written randomly.

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 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 the ROM, which plays an important role in the configuration performance of the mobile phone.

ROM 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 a ROM?

Some friends may know more about computers, in fact, the ROM and RAM on the mobile phone and the ROM and RAM on the computer mean the same thing, both are the names of the memory. Among them, the full English name of ROM is READ Only Memory, and the Chinese name is READ ONLY Memory, in more popular terms, ROM we can understand as the hard disk of the mobile phone, which is used to store things in it.

Peculiarities of ROMs on mobile phones.

However, the ROM on the mobile phone is a little different from the hard disk we generally understand, because although the ROM on the mobile phone can store things, but we can only read and not write under normal circumstances, which is why it is called "read-only memory", only under specific professional conditions, we can write things to the ROM.

In view of the particularity of the ROM, many mobile phone system files are stored in the mobile phone's ROM, so that under normal circumstances, we can not modify the mobile phone's system files, but at present, through some special means, we can also realize the writing of things into the ROM, this situation is actually what we often call flashing, brushing the system, so this is also called brushing ROM.

What is RAM?

ROM and RAM are the names of storage, the full English name of RAM is random access memory, the Chinese name is random memory, the so-called random memory refers to RAM can be randomly written and read operations, its main access is a variety of dynamic data, once the phone power off or the program is completely closed, the data stored in RAM will be lost. From the above professional description, we can actually know that if you explain what RAM is in short, RAM is the memory of the mobile phone.

RAM determines how quickly your phone responds.

rom: read only memory. Information is not lost after power failure, such as the BIOS chip used to boot the computer.

Access speeds are low, (compared to RAM) and cannot be rewritten. Because it can't rewrite the information and can't be upgraded, it's rarely used nowadays.

ROM and RAM are the two models of memory inside a computer:

ROM represents read-only memory, that is, it can only read out information, can not write information, the information in it is still saved after the computer is turned off, and it is generally used to store fixed system software and fonts.

RAM represents read-write memory, which can be used by any storage unit for read or write operations, the information in it will not be saved after the computer is turned off and the computer needs to be reloaded when it is turned on again, usually used to store the operating system, various running software, input and output data, intermediate results and exchange information with external memory, etc., we often say that memory mainly refers to RAM.

ROM and RAM both refer to semiconductor memory. The original meaning is: ROM means Read Only Memory, which means that this kind of memory can only be read, 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, hence the name.

But that was 30 years ago. In the 30 years that semiconductor and computing technologies have advanced by leaps and bounds, their meanings have changed somewhat.

Now ROM usually refers to non-volatile memory, or rather, no power down. They can still hold data when the system is powered off. So the disc also has the term cd-rom or ***-rom.

RAM usually runs out of power and has no data, typically like a computer's memory, which needs to be reloaded from the hard disk when the system restarts. Sometimes, if the data can be erased, the concept of RAM will also be borrowed, such as ***-RAM, which is actually just a *** disc that can be erased, not a real semiconductor memory.

What exactly is the difference between RAM and ROM?

The ROM is to put your mobile phone system, and your mobile phone system is installed in the ROM.

As for RAM, it is to install your running program, run a program, after this program is opened, you must have space to process this program, otherwise it is useless if you turn off the CPU.

So sometimes it starts to get stuck when there are more running programs, which is the lack of RAM memory.

Running memory is RAM, which is used to run the system and software, and the larger the RAM, the more software can run at the same time. The system will also run faster. A memory module similar to a computer.

If the ROM is insufficient, you can make up for it with a TF card, and smart phones can generally support 32G cards.

For Android, RAM refers to the phone's memory, and ROM generally refers to a read-only partition of your phone's internal memory. It is the space where you install the software, and the partition format is generally ext3 or ext2 in Linux disk format

If you buy**, choose a big RAM, because the ROM is small, you can add a memory card!

Something like this:

ram = memory.

rom = hard disk.

SD = Removable Storage Device, which stores some general purpose files.
