CPU

The CPU (Central Processing Unit), is the primary hardware component of a computer system responsible for executing instructions of a computer program.

significant role in determining the overall speed and capability of a computer system

Memory & storage

The elements responsible for storing data and information , crucial in computing.

-Memory (RAM) is volatile and provides the CPU with quick access to actively used data and instructions. -Storage (HDD/SSD) is non-volatile and used to permanently store data. -SSDs are faster and more energy-efficient than HDDs. -Cache Memory sits between RAM and the CPU, providing high-speed data access.
