Here are four computer hardware components:

1. Central Processing Unit (CPU): Often called the "brain" of the computer, it performs most of the processing inside the computer.
2. Random Access Memory (RAM): This is a type of volatile memory that stores data and program instructions currently being used by the CPU for quick access.
3. Hard Drive (HDD) or Solid State Drive (SSD): These are storage devices used for permanently storing data, such as the operating system, applications, and user files.
4. Motherboard: This is the main circuit board that connects all the other hardware components, allowing them to communicate with each other.
