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.

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.

1.4GHz Qualcomm Snapdragon 425
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.

Adreno 308,500MHz
RAM (Memory) 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.

2 GB
Internal Storage Internal Storage is a data storage space (flash memory) mostly used in smartphones, tablets and other electronic devices where operating system, apps, music, photos, videos, files and other user data Is stored.

16 GB
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.

Battery

Battery Type Battery Type => Cell phones run on various kinds of batteries depending on the manufacturer, phone size or shape and features. There are basically four types of cell phone batteries => Lithium Polymer, Lithium Ion, Nickel Metal Hydride and Nickel Cadmium.

Li-Ion (Lithium Ion)
Capacity Battery Capacity is a measure (typically in Amp-hr) of the charge stored by the battery, and is determined by the mass of active material contained in the battery. The battery capacity represents the maximum amount of energy that can be extracted from the battery under certain conditions.

3120mAh

Connectivity

Bluetooth Bluetooth is a wireless communications technology for exchanging data between mobile phones, headsets, computers and other network devices over short distances without wires, Bluetooth technology was primarily designed to support simple wireless networking of personal consumer devices.

Bluetooth 4.1
Wi-fi Wi-Fi is a popular wireless networking technology using radio waves to provide high-speed network connections that allows devices to communicate without cords or cables, Wi-Fi is increasingly becoming the preferred mode of internet connectivity all over the world.
