Final answer:
Option c) 'Device drivers are not essential for proper device functioning' is not true. Device drivers are crucial for communication between the operating system and hardware devices, and without them, a device may not function correctly or at all.
Step-by-step explanation:
The student's question is about the role of I/O devices and device drivers in computer systems. While options a), b), and d) are true, option c) is not true. Here's why:
- Device drivers are indeed essential for the functioning of hardware devices. They act as a translator between the operating system and the hardware, enabling communication.
- I/O devices stand for input/output devices, and examples include keyboards and printers, serving as a bridge for data to enter and leave the computer system.
- I/O devices can be both externally connected to the computer, like a mouse or printer, and internal, such as a built-in camera on a laptop or an SSD drive.
Therefore, the incorrect statement is c) Device drivers are not essential for proper device functioning. Without the proper device driver, the operating system might not recognize or fully utilize the functionalities of a hardware component.
