π‘π€πŒ
- Volatile memory; stores data currently in use by the system.
- Data is lost when power is off.
- Fast read/write speeds.
π‘πŽπŒ
- Non-volatile memory; contains permanent instructions (e.g., BIOS).
Cannot be modified easily.
𝐂𝐀𝐂𝐇𝐄
- Very fast, small memory located inside or close to the CPU.
- Temporarily stores frequently used data for quick access.

- Magnetic storage, slower than SSDs but cheaper.
- Used for storing large amounts of data.

𝐒𝐒𝐃 (Solid State Drive)*:
- Faster than HDDs, no moving parts.
- Used for OS, software, and quick access data.

Software is a set of instructions, data, or programs that tell a computer what to do and how to perform specific tasks, unlike its physical counterpart, hardware. It is the intangible part of a computer system that includes applications like word processors and games, as well as the system software that manages the computer's hardware.

Motherboard:
The main circuit board that connects all other components.
CPU (Central Processing Unit): The "brain" that processes instructions and runs the operating system and applications.

RAM (Random Access Memory):
Short-term memory that the CPU uses to quickly access data.
Storage Device: Long-term storage for data, such as a Hard Disk Drive (HDD) or Solid State Drive (SSD).
Power Supply Unit (PSU): Converts wall power into the correct voltage for the computer's components.
GPU (Graphics Processing Unit): Handles all graphics and video output, also known as a video card.
