Motherboards & Connectors Basics
What is a motherboard?
is the main circuit board that connects computer components
What is the motherboard power cable?
This is the 24-pin ATX power cable that supplies main electrical power from the power supply unit to the motherboard.
What is the power supply unit (PSU)?
This device supplies electrical power to computer components.
What is an operating system?
This software manages computer hardware, runs applications, and provides an interface for users to interact with the computer.
What is overheating or power instability?
This hardware failure symptom includes sudden computer shutdowns during use.
What is SATA cable?
This connector type is commonly used for modern storage devices.
What is a floppy drive cable?
This legacy cable was used for floppy disk drives.
What are cooling fans and heat sinks?
These components remove heat from CPUs
What is POST?
This startup process tests hardware components before loading the operating system.
What are display artifacts?
These are abnormal screen patterns or color distortions.
What is the motherboard chipset?
This system manages communication between CPU, RAM, and peripherals.
What are PCIe expansion slots?
These slots are used for installing graphics, network, and sound cards.
What is RAM?
This memory type temporarily stores running programs.
What are BIOS or UEFI?
Firmware that controls hardware initialization before OS loading.
What is ECC memory?
Technology that detects and corrects memory errors.
What is the CPU socket?
This component physically holds the CPU on the motherboard.
What is an IDE (PATA) connector?
This legacy connector was used to attach internal hard drives and optical drives before SATA became common.
What is the CPU?
This component executes program instructions in the computer.
What is the difference between alternating current (AC) and direct current (DC)?
AC is the current supplied from the electrical outlet, while DC is the stable current used to power motherboard components and internal computer hardware.
What is SMART diagnostic monitoring?
This tool is used to test hard drive health and detect potential drive failures.
What are expansion slots?
These are motherboard slots used to install expansion cards such as graphics cards or network cards..
What is a SATA data cable?
This cable is used to connect storage devices such as SSDs or HDDs to the motherboard for data communication.
What is a solid-state drive (SSD)?
This storage device has no moving mechanical parts and is faster than HDDs.
What is TPM (Trusted Platform Module)?
This security feature prevents unauthorized access by storing encryption keys in hardware.
What is a SATA power cable?
This cable supplies power from the power supply unit directly to SATA storage devices such as SSDs and hard drives.
