Component guide
Networking, ports and audio
Ethernet and Wi-Fi connect the computer to a network; Bluetooth pairs compatible accessories. USB ports connect devices, and audio circuits handle sound and microphones.
How does it work?
The network adapter exchanges data with other devices. Ports connect accessories using different protocols. The audio system converts digital and analog signals to play or capture sound.
Concepts you should know
Key concepts: these functions may be built into the motherboard or added using cards and adapters. A connector's shape does not guarantee all its functions.
An everyday example
During a video call, the network adapter transmits data, the microphone captures audio and the camera provides images. Drivers allow the operating system to use these devices.
How it connects to the rest of the computer
Connections may be built into the motherboard or added through USB or expansion cards. A USB-C port can offer different functions depending on the computer.
