Accepted Answer

POST stands for Power-On Self Test, which is a diagnostic testing process that a computer undergoes when it is first turned on to ensure that all hardware components are functioning properly. NO-POST refers to a situation where the computer fails to complete the Power-On Self Test and may indicate a hardware failure.

BIOS, or Basic Input/Output System, is a firmware that is built into the motherboard of a computer and is responsible for initializing and configuring hardware components during the boot process.

There are several types of RAM including DDR, DDR2, DDR3, and DDR4. Each type of RAM has different speeds and capabilities.

Practical client scenarios that an IT support specialist may encounter could include issues with software installation, network connectivity problems, virus/malware infections, hardware malfunctions, etc. Resolutions could involve troubleshooting the issue, updating software, replacing hardware components, etc.

Components associated with a system board include the CPU, memory slots, expansion slots, chipset, BIOS, ports (USB, Ethernet, audio, video), and connectors.

Types of display include LCD (Liquid Crystal Display), LED (Light Emitting Diode), OLED (Organic Light Emitting Diode), and CRT (Cathode Ray Tube).

A switch is a networking device that connects devices within a network to enable communication. A circuit is a closed loop that allows electricity to flow through it.
