What does the free space of an Android phone 16GB and the internal memory of 4GB ROM mean

16GB is the TF card, which is embedded in the mobile phone, 4grom is the C disk of the mobile phone, and 16GB is the drive letter for you to store the game. Simple you understand that,4GROM is equal to C disk,16G is equal to D,E,F disk on the computer,I don't know,My phone is not the kind of embedded memory card,My phone can install a memory card,You try to use the 360 mobile phone assistant,He will help you load the software into the SD card。

I'm using i9100 now, which runs 1G memory (equivalent to computer memory), internal storage, which can be used to install software + storage data), and flash memory (equivalent to a memory card, which can store data).

Question addendum: No, it can only be installed in 2G internal storage, 2G. Enough for an Android phone.

However, some large-scale games with hundreds of megabytes are in the form of the main program + data package, and the main program must be installed in the internal storage, and the hundreds of megabytes of data packets can be put into flash memory.

The available space is equivalent to a computer hard disk, dedicated to songs, movies, etc., and the rom doesn't seem to be so large, which is equivalent to the computer's memory module, understand?

Shenma, yes, 4GB ROMs are a lot of sight, the key is how big is the RAM?

For the so-called RAM is actually the meaning of running memory, people refer to it as memory, its role is that when the system runs after booting up a part, the larger the remaining running memory, the faster the mobile phone, the more programs run, and the less remaining.

The meaning of ROM capacity is similar to the capacity of the "C drive" in a mobile phone. Because too many ROM files will also affect the speed, but the files and programs stored in the ROM will be read much faster than those stored in the card.

RAM is the equivalent of your computer's memory, which determines how much software your phone can run (install), or how much software it can use.

ROM is equivalent to the system disk of the computer, and the system of the mobile phone is installed in it.

ROM usually refers to the mobile phone system and the space that can be installed with programs, the larger the ROM, the more programs can be installed directly in the system. Usually the manufacturer's instructions are to use 1GB of ROM, but in essence there is only 340MB of free space, which is normal. This is because the system itself takes up half of the space (looking at different UI systems designed by different phone brands will lead to different footprints), and then the factory-preset third-party software also takes up tens of MB of space, which would explain why there is only 340MB left.

RAM refers to the temporary space required to run the system and software, and it means the same as the memory on a computer. The more RAM you have, the more programs you can open at the same time, and the smoother some games that require a lot of RAM. Similarly, boot system services and some software automatically run in the background, which will occupy a part of the resource space.

If the manufacturer's statement is 256MB, it is normal to have less than 100MB after the actual boot.

The mobile phone comes with 340M, running memory 256M, (but the boot is only more than 100 points, the system occupies a lot) ROM seems to be the firmware disk that comes with it, the C disk of the computer.

RAM: 1G means that BAI has 1GB of RAM.

This memory (internal memory du) does not refer to the usual zhi dao"Memory", but the real inner version of the storage, and the usual.

The configuration is very high.

Bai RAM refers to RAM ROM refers to solid memory DU storage To put it bluntly, RAM is the luck of mobile phones.

The speed of the internal sequence of the program can be seen in the remaining space of the RAM, which is like a computer memory module; ROM is the built-in space of the phone, which you can use to put things, such as the hard disk in the computer. Hope it helps.

RAM is similar to the memory of a computer, and the data disappears when the computer is shut down; ROM is similar to hard disk, power down data retention.

The memory of the mobile phone is divided into two categories, one is the running memory and the other is the storage memory:

1. Running memory, that is, random memory, abbreviated as RAM in English, is equivalent to the memory module of the computer, how big the factory is, and the capacity cannot be expanded, generally 1G or 2G, not more than 4GB;

2. Storage memory, it is customary to call ROM (read-only memory) in mobile phone parameters, in fact, it is not very accurate, because it is not read-only, it is more accurate to call the fuselage memory or mobile phone memory, which is equivalent to the hard disk of the computer, and the capacity is generally more than 4GB. If the mobile phone supports inserting cards, it can be expanded. The full series of Apple mobile phones does not support plug-in cards and cannot be expanded.

Applications installed on mobile phones are generally installed here by default. This is the phone's system memory space.

ROM originally refers to read-only memory, which generally refers to the part of memory occupied by the operating system of the mobile phone. However, since the operating system generally does not occupy the memory, the part left behind is turned on the write permission, and it becomes the fuselage memory. The body memory is originally part of the flash memory used by the ROM.

Mobile phone memory ROM is actually understood as the hard disk of the mobile phone. It's space! The system is here.

RAM is actually equivalent to the memory of a mobile phone, which refers to random storage, also known as flash memory.

ROM (Z disk) is read-only storage, mobile phone firmware is placed in read-only storage to prevent loss, ROM is usually used to solidify and store some programs or data written by manufacturers, used to start the mobile phone and control the working mode of the mobile phone, the size of the general ROM has no practical significance. The internal memory (C drive) is like a hard disk on a computer, which can be used to store data. RAM (D disk) is the cache in the mobile phone, that is, the memory, which is the space where the software can run

RAM is random access memory, and the power-off data disappears.

ROM read-only memory, power-off data still exists, note that now ROMs are usually electrically rewritable ROMs, which means readable and writable.

Flash memory refers to memory cards and USB flash drives, which are variants of electrical rewritable ROMs, with faster read and write speeds than electric rewritable ROMs, and data retention in power failure.

Mobile phone RAM works the same way as a computer.

512ROM storage system, the remaining part can be installed software to store files, the role is equivalent to the computer C disk.

The 16G free space is the integrated flash memory, which acts as a computer hard drive.

Install software into flash memory, unless it can only be installed in the ROM.

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.

RAM is the equivalent of a cache, and ROM is the storage medium.
