9. Basic Input Output System BIOS
ICT - Module 2: Operating System Administration.
In this video, we'll cover the Basic Input/Output System (BIOS) in detail. The BIOS is the first program that runs when you turn on your computer, acting as a bridge between the hardware and the operating system. We'll explore how this firmware initializes components and how to properly configure it for stable operation of your PC.
What you'll learn in this episode:
BIOS definition and role: Why a computer needs a set of instructions in read-only memory and how it performs the POST self-test.
System structure: What logical components does the BIOS consist of, from the boot loader to the Setup Utility interface.
Main functions: Initialization of the motherboard, processor, and memory, as well as control of the boot sequence from media.
Using BIOS Setup: How to enter the setup menu and correctly change the date, time, security passwords, or overclocking parameters. Evolution of UEFI technologies: What are the advantages of the modern UEFI interface, such as support for drives larger than 2 TB and Secure Boot mode?
Firmware Updates (Flashing): When is it necessary to update the BIOS to support new processors and how to do it safely using official utilities?
Troubleshooting: What to do if the time constantly resets or the system doesn't recognize a new drive.
Target Audience: This material is intended for vocational, post-secondary, and non-tertiary education, necessary for the development of digital competencies.
