The obvious answer would be the Power Supply Unit (PSU). This starts the computer and without it nothing can work. On the other hand if you have a faulty mother board or RAM, the computer would switch on but nothing would be shown on the screen. The PSU is found on the highest part of the tower. Also check the the switch (if it has) is switched on, and that the power supply cable (the 3 pin one) works.

What are some options available for computer hardware recycling?

What is the difference between BIOS and device driver?

In IBM PC compatible computers, the basic input/output system (BIOS), also known as the System BIOS or ROM BIOS , is a de facto standard defining a firmware interface. When in computing, a device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device.


What test does startup BIOS perform when you first turn on a computer to verify it can communicate with essential hardware devices?

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 is the term given to the hardware component of the motherboard that stores the first code that is run by the computer when it is turned on?

What is the first thing that BIOS checks?

Startup BIOS first checks all the essential hardware components to make sure they're working and displays its progress on-screen.

What is fault coordination?

Fault coordination is the process of ensuring that protective devices in an electrical system are coordinated such that the device nearest to the fault disconnects first, effectively isolating the faulted section and ensuring minimal disruption to the rest of the system. This process helps to improve the reliability and selectivity of the protection system.

When you're taking your first drivers test and you get into an accident and you kill someone is that your fault?

Well, I would assume so. You were driving the car, and you were in control. If I am right, you can't blame your driving school for the accident. So in my personal opinion, yes, it is your fault! :[


What is the core part of an operating system and what is the first part to be loaded?

The core part of an operating system is typically the kernel, which manages system resources, hardware communication, and process management. The first part to be loaded during the boot process is the bootloader, which initializes the system hardware and loads the kernel into memory to start the operating system. Once the kernel is loaded, it takes over control and manages the overall operation of the system.
