Lets Talk about Hardwares Present in Smartphones

A processor executes what you want your smartphone to do.

CORE

An element found in the main processor that reads and executes instructions. Devices began with a single-core processor, but engineers created more powerful devices by including more cores in one device.

That led to dual-core devices. Soon there were quad-core processors (as in four cores), and now there are hexa- (six) and octa-core (eight) smartphones and tablets.

CHIPSET

In a mobile phone, combination of Chipset and CPU is called a SoC (System on Chip) which integrates all the components on a single chip.

Unlike in computers, CPU is soldered on the Chipset inside a mobile device which tends to improve the performance, and saves lot of space.

1GHz processors complete system tasks and hardware multimedia acceleration at high clock speeds and with low power consumption.

Processor Companies are Qualcomm (SnapDragon), MediaTek, Spreadtrum, Intel (Atom), Marvell (PXA), Nvidia (Tegra), Samsung (Exynos), Huawei/HiSilicon, Allwinner, and Rockchip.

GPU

A Graphics Processing Unit is a co-processor that takes on graphical calculations and transformations so that the main CPU does not have to be burdened by them. 

The use of a GPU can greatly increase the performance of a device, especially when used for tasks such as 3D gaming

RAM-Random Access Memory

Ability of a phone to run multiple applications simultaneously.

For example, 256 MB RAM-enough to run handful applications with no decrease in performance. Today 1G, 2GB, 3GB, 4GB, 5GB and more are there.

ROM-Read Only Memory and Internal and external storage

ROM stands for “Read Only Memory” and is memory that resides on your computer mainboard to store vital instruction code that almost never changes — hence “read only.”

You can’t write to it normally, your device only reads data from it and this data is usually instructions (firmware or the like) for your computer.

It’s not something that is used for the day-to-day computing of the user, and usually it’s only changed through very low-level methods like firmware updates.

This is a completely different thing from storage memory, which a lot of people erroneously use the term form. Storage memory is the actual non-volatile memory of your phone used to keep your day-to-day things like photos, music, and additional apps/programs.

Most phones have a core “internal storage” memory along with ways for expansion, usually by microSD cards today.
