- Connects all components and peripherals.

Random Access Memory (RAM)
- Temporary storage that allows fast access to data.
- Affects the speed of everything from applications to the operating system.

Storage Drives
- Hard Disk Drive (HDD): Older technology, generally offers more storage at a lower price.
- Solid State Drive (SSD): Newer technology, faster, more efficient, and more reliable, though typically more expensive per gigabyte.

Graphics Processing Unit (GPU)
- Handles rendering of images and videos.
- Essential for gaming, video editing, and graphic design.

Power Supply Unit (PSU)
- Converts electrical power from an outlet into usable power for the computer.

Input and Output Devices
- Keyboard and Mouse: Main input devices for user interaction.
- Monitor: Displays visual output from the computer.
