INPUT DEVICES

Starting at [01:10], this section of the lesson focuses on correcting the previous assignment concerning booting a computer, then transitions to introducing input devices, the topic for the day's lesson. The six steps in the booting process are: startup, POST (Power On Self Test), loading operating system, system configuration, loading system utilities, and user authentication. Startup is the initial step when electric power is supplied. The POST tests that the peripheral components work, and if all goes well, the operating system takes over. It loads drivers into the main memory, and those create compatibility. At the end the user may be asked to authenticate with login info. At [06:23] The lesson plan for input devices is introduced. The lesson will cover these topics: identifying types of input devices, enumerating examples, real-life applications, presenting concepts and doing exercises.
