Many users are confused by ROM and RAM when sellers introduce them to Android phone and iPhone. RAM (Random Access Memory) and ROM (Read Only Memory) are two very old technologies that were created in the early days of computing. Nowadays, they are still used in smartphones. The main difference between RAM and ROM is their usage. In the section below, we'll help you tell them apart..
Part 1. Basic knowledge of ROM
What is ROM? ROM, read-only memory, is the storage capacity of your device. In the past, a mobile phone was always equipped with 4 GB, 8 GB and 16 GB of storage. Now the storage of the smartphone is upgraded to 32GB, 64GB and 128GB.
In the iPhone, the ROM is divided into two parts: one is occupied by the system, which cannot be operated by users; The other, which is like the hard drive of the computer, can be operated by users. The older generation of iPhone would have a capacity of 16 GB. However, the actual capacity was only 12 GB. With more and more applications installed on the phone, there was less and less storage available. . Lots of users have complained about this. So, now Apple has improved the capability of the iPhone..
Part 2. Know RAM
What is RAM? RAM, random access memory, is a memorable practice to transport. There are two types of RAM-DRAM and SRAM. However, RAM is generally considered to be internal storage. For example, the storage combination in the cell phone includes 2BG + 10GB, 3GB + 32GB, 4GB + 64GB and more. Among them, 2 GB, 3 GB and 4 GB are the storage unit of RAM, internal memory.
However, many users may wonder that the actual RAM is always less than what was promised. For example, if you buy an Android with 4 GB of RAM, you may require that the RAM is only 3.x GB when you turn it on. The worst part is that the actual RAM can remain 2.x GB. This is because your phone's GPU takes up part of the RAM..
Part 3. Is it necessary to upgrade the phone with 16GB ROM only?
Now cell phone ROM is at least 32 GB. And many mobile phones are allowed to expand storage with external SD card. This is good news for those who like to watch videos and play with apps in their phone.
To save ROM, you can delete some unnecessary files and uninstall some apps from your device.
