RAM

Random Access Memory (RAM) is a type of memory that the processor uses to temporarily store data and instructions that are actively being used. The amount of RAM available affects how smoothly the smartphone can run multiple applications and perform complex tasks.

Larger RAM allows the smartphone to handle more applications simultaneously without slowing down, enhancing multitasking capabilities.
RAM is volatile memory, meaning that data is lost when the device is powered off.
The amount of RAM required varies depending on the intended use of the smartphone. High-end smartphones typically have 8GB or more of RAM, while budget models may have 2GB or less.

Storage

Storage is used to permanently store data, such as apps, photos, videos, and documents. The amount of storage available affects how much data can be stored on the device.

Storage is typically measured in gigabytes (GB) or terabytes (TB).
There are two main types of storage: internal storage, which is built into the device, and external storage, which can be added via a microSD card.
Internal storage is typically faster than external storage but is limited in capacity. External storage provides additional space but is generally slower.

Display

The display is the primary interface for interacting with the smartphone. It is responsible for displaying images, text, and videos. The quality of the display is determined by factors such as screen size, resolution, and technology.
