There is an important difference and is similar to that that exists in our brains with short and long term memories. In current mobiles (and on tablets and computers and …) there are two types of memory, storage (where we save the photos, videos and documents) and RAM (acronym of random access memory) whose function is similar to the short term: storing data and instructions that the processor needs for its immediate use. RAM allows rapid access to information, significantly accelerating device operations and facilitating multitasking mode.
But, as is the case with storage, We can saturate the RAM if we have many open windows and demand from the processor to reach the limit.
The reality is that current mobiles, mainly those of high -end, and even the most affordable models, include almost as much RAM as a mid -range laptop. This is because we use our phones for various tasks, from navigating between innumerable applications to video games with a high degree of demand in processing material and graphics card.
When this occurs, the first response of the system is to compress the applications that are already in the RAM using ZRM (a memory inside the memory, in basic terms). The Zram occupies more or less space depending on the demands of the system: Acts as a dike’s lock, releasing the pressure.
Now, for this to happen we must be doing something very good (in terms of engineering) because Otherwise the “lock” does not open. So, in theory, it is possible to run out of RAM. If we abuse the applications installed, if these are of great demand and if we use many at the same time, we reach that border. What happens in those cases?
When a smartphone runs out of RAM, it can cause three immediate consequences. The first one is that the device will have difficulty executing applications fluently, which can cause unexpected delays, blockages, blockages or closures. In extreme cases, the entire operating system could stop responding.
When the RAM is full, it is also possible that the phone cannot store all applications in memory in memory. This can cause applications to block, since the system has difficulties in managing resources.
Finally, we have the instability of the system. In severe cases, running without RAM can cause the phone to stop or even block. The operating system could have difficulty managing the lack of available memory, which may require a restart.
Even Applications and processes in the background can be affected by little RAM. The system could automatically close the applications in the background to release resources, which can affect its functionality.
Some phones use an exchange space in storage as an alternative solution when the RAM is full. However, Accessing data from the exchange space is much slower than from RAM, which causes greater performance degradation.
To avoid this, it is recommended close windows, clean applications every so often, to erase the ones we no longer use and control, in adjustmentsthe use of RAM, to know its state.
