The BIOS (Basic Input-Output System) loads a ROM (Read-Only Memory; a chip that stores permanent bootup instructions) that performs a POST (Power-On Self-Test) when the computer is first powered on, or when the CPU (Central Processing Unit) is soft reset via a triple fault or an untrapped reset command through the keyboard port (by sending the value 254 to the hardware port 100). The POST checks to make sure that there is system memory, and usually at least one drive device (disk or hard drive), and all the other various parts that make up the core functionality of the computer.

What kind of computer hardware equipment are considered output devices?
There are many pieces of computer hardware equipment that are considered output devices. Some examples of computer output devices are speakers, headphones, monitors, and printers.
How does computer hardware communicate with the software?
I/O devices like Keyboard, Mouse, Monitor, Speakers are used to for the computer to communicate with the user. The Operating System uses software called drivers to interact with these hardware devices. Altogether, this is called the user interface.
What are the example of digital devices?
These are the digital devices solenoid, computer, computer hardware, mobile phone, camera etc.
Hardware devices that accept data in a form the computer can use are called?
Input devices.
What is the transmission protocol between a computer and a peripheral device?
The way a computer communicates with a peripheral device is through a device driver. A device driver is a low level computer program that allows higher level programs to communicate with a hardware device connected to the computer bus. Device drivers are hardware dependent and specific to an operating system.
What test does startup BIOS perform when you first turn on a computer to verify that it can communicate with essential hardware devices?
That is called POST or Power-On Self-Test. This process tests and initializes the essential devices. It may also display a splash screen, provide information, and give you the chance to change some of the settings.
What is the name of the software program that lets your computer communicate with a hardware device?
The name of the program that lets your computer to communicate with hardware devices is call KERNEL. Kernel communicates between hardware and software of a computer and manages how hardware resources are used to meet software requirements
