Answer:
The system unit is the central component of a computer that houses the motherboard, CPU, memory, and other essential components. It is responsible for processing data and communicating with other devices attached to it. One of the most critical functions of the system unit is its ability to recognize new devices attached to it.
In modern computers, this process is automated through plug-and-play technology. When a new device is connected to the system unit, it sends a signal to the operating system, which then searches for drivers and installs them automatically. This allows users to easily connect new devices such as printers, scanners, and external hard drives without having to manually install drivers.
However, there are instances where the system unit may not recognize a new device due to compatibility issues or driver conflicts. In such cases, users may need to manually install drivers or troubleshoot any issues that arise.
Overall, while it is possible for the system unit to recognize new devices attached to it through plug-and-play technology, there may be instances where manual intervention is required.
