Software


Operating System OS => Every computer system run on a base software called Operating System (OS). Operating System controls all basic operations of the computer (such as smartphone, PDAs, tablet computers and other handheld devices). The Operating System allows the user to install and run third party applications (apps), apps are used to add new functionality to the device.	Android 11, Funtouch 11.1 Android 11
User Interface UI or user interface of a device is the look and feel of the on-screen menu system. How it works, its color scheme, how it responds to button presses, all of these things are part of the user interface.	Realme UI 2.0

Hardware


Chipset Chipset is a group of integrated circuits designed to perform one or a more dedicated functions, often with real time computing constraints, Popular smartphones are equipped with more advanced embedded chipsets that can do many different tasks depending on their programming.	Mediatek MT6765 Helio P35 (12nm) MediaTek Helio G85 (12nm)
CPU CPU (Central Processing Unit) mostly known as processors, CPU processes instructions in order to carry out certain functions that make your device operate properly. Processors are often described as the brain of computers, smartphones and tablets, Smartphones and tablets rely on processors to carry out their every task, Processors are an incredibly important factor in selecting any type of computing device, including your smartphone.

GPU GPU (Graphics Processing Unit) is a single-chip processor designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display, This includes things such as lighting effects, object transformations, and 3D motion.	PowerVR GE8320 Mali-G52 MC2
Memory (RAM) RAM (Random Access Memory) is a type of computer memory that can be accessed randomly, any byte of memory can be accessed without touching the preceding bytes that allows information to be stored and accessed quickly from random locations. RAM is the most common type of memory found in computer systems, smartphones, tablets and other electronic devices.	64/128GB Built-in, 4GB RAM (+1GB extended RAM) 128GB Built-in, 4GB RAM
Card Slot Memory Card Slot is a special slot for inserting a memory card. Memory cards allow you to expand the phone's built-in memory, A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote computing devices such as mobile phones, mp3 players, digital cameras.	microSDXC, card slot microSDXC, card slot
Sensors Sensors are electronic components that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure and location, The output is generally a signal that is converted to use in computing systems, a location sensor, such as a GPS receiver is able to detect current location of your electronic device.
