Use cases of a system bus

  1. Smooth data flow. A system bus inside your computer ensures that different parts, like the brain (CPU) and memory, can talk to each other easily. This helps your computer run programs.
  2. Connecting devices. It’s what lets you plug in things like a printer, keyboard, or mouse and have them work right away. The system bus helps these devices chat with your computer.
  3. Graphics power. If you enjoy gaming or working with graphics, the system bus helps your computer’s graphics card work with the main CPU and memory, ensuring images and videos look great.
  4. Quick access to files. When you open files or programs, the system bus helps your computer grab them from your storage drive super fast, so you don’t have to wait long.
  5. Network connection. A system bus helps your computer connect to the internet and share data with other devices on a network. This function plays a part in making online activities like browsing and video calls possible.
