What does RAM, ROM, NPU, mAh, PDAF mean? You know your smartphone has such a lot of RAM and ROM, a few thousand mAh, PDAF technology in the camera, an NPU for artificial intelligence tasks ... What do all these terms mean? For an advanced user this may be a basic nomenclature, but many people ask us about the meaning of these terms, as they don't know what they refer to.
We provide a small and simple glossary for anyone who wants to know more about these terms that we read every day in the technical specifications, and it is always good to know the components that make up our phone.
RAM, ROM, NPU, mAh, PDAF terms we read daily
Here you will find a list with some of the most used terms in Android telephony.
- Adware- Unwanted advertising software from the user shows ads.

- CMOS: cheap chip to create, made up of independent cells. It is responsible for digitizing the pixels of the photograph.
- CPU: central processing unit. Hardware element in which most of the code calculations of our device are done. The greater the CPU power, the greater the processing capacity.
- Dual Pixel: technology inherited from reflex cameras. It allows a faster approach than PDAF, thus increasing the sharpness and improving the final results.
- But by the full GPU acceleration tech: graphics processing unit. Hardware element in which most of the calculations related to the graphics operations of our device are made.
- GPS: global positioning system. System that allows us to determine the position of any object, vehicle, area, person ...
- JPEG- A compressed file format that applies certain predefined values to the photograph. It reduces the weight of the original file and allows it to be used and viewed on most platforms.
- Kernel: fundamental software in every device responsible for the correct communication between software and hardware.
- Team- Sudden drop in speed of an application, due to extreme connection congestion or insufficient processing power of a part of a device.
- mAh: milliamps. Unit of electric charge that we use to know the total capacity of a battery.
- MODE: edit. Software extension that allows you to modify aspects of the terminal such as audio, power consumption, camera ...
- NFC: wireless technology that works actively and passively, able to identify us, pass data, automate actions ...
- Nanometer: unit of length equivalent to one billionth of a meter (1 nm = 10-9 m) or one millionth of a millimeter.
- NPU : neuronal processing unit. Hardware element responsible for most of the activities related to artificial intelligence. Download the work of the CPU and GPU.
- PDAF: focus by phase. Type of approach with software inherited from professional photography, in charge of improving photographic results. The first mobile that implemented it was the Samsung Galaxy S5 in 2014.
- RAM: random access memory. Work memory into which most of the CPU instructions are loaded.
- RAW; raw file offered by the camera sensor. Unlike JPEG, it has no added compression or configurations. It allows the complete editing of the file, containing all the sensor information.
- Recovery: device recovery mode. It allows you to perform operations such as resetting our device, as well as loading operating systems, MODs
- ROM: the memory ROM yes refers to read-only hardware. Contains the device firmware.
- Root: root access. Modification of our system that allows access to practically all folders on our device, as well as the ability to modify them.
- SIMs.: physical or virtual card responsible for identifying us in the telephone network.
