    Study Notes

    Microprocessor Parallelization and Virtual Processors

    • Hyper-threading is a form of microprocessor parallelization that enables each physical processor to function as two virtual processors.

    Expansion Slots for Graphics Adapters

    • PCI Express (PCIe) is the preferred expansion slot type for high-performance graphics adapters to maximize data throughput and speed.

    Error-Checking Schemes

    • Parity checking is a non-error correction scheme used for error-checking in main memory.

    Booting from USB Flash Drives

    • If a computer boots from the hard drive instead of the USB flash drive, likely causes include incorrect boot order settings in BIOS/UEFI or an incompatible USB drive.

    CMOS Memory

    • The date and time are stored in CMOS memory, while system configurations like boot sequence and device settings are typically not retained when the system is powered off.

    Initial Bootup System Checks

    • Power-On Self-Test (POST) is the series of checks executed during the initial bootup of a computer to ensure all system components function correctly.

    Non-System Components

    • Peripheral devices such as printers, monitors, and other external hardware are not considered internal system components.

    Secure Boot Technology

    • Secure Boot, dependent on UEFI, ensures that the system only loads trusted files during startup to prevent tampering.

    Communication Circuitry

    • A motherboard contains all circuitry necessary for different components and devices to communicate and function together.

    Hardware Security Module (HSM)

    • HSM is a specialized tool for the protection of cryptographic keys and processes; certain configurations enhance security.

    Processor Speed Enhancement

    • Cache memory allows a processor to execute instructions and read/write data at speeds greater than standard RAM.

    Motherboard Compatibility

    • An ATX motherboard should be replaced with another ATX motherboard to ensure compatibility with the case and components.

    Flashing UEFI

    • A successful UEFI flash requires a stable power source during the process to avoid system failures; having a backup is often recommended.

    PCIe Slot Throughput

    • A PCIe 2.0 x16 slot offers a total throughput of up to 8 Gbps (gigabits per second).

    Motherboard Form Factors

    • The Mini-ITX form factor has dimensions of 120 mm x 120 mm and is useful in compact builds.

    System Performance Improvement

    • Increasing RAM allows for better multi-tasking capabilities and the ability to run more applications simultaneously without slowdowns.

    Low Power Requirement Motherboard

    • For a new PC requiring a smaller case and reduced power, consider using a Mini-ITX motherboard to match the specifications.

    Peripheral Functionality Issues

    • If onboard peripherals like USB and LAN are malfunctioning, it may indicate issues with the motherboard itself.

    CPU Socket Compatibility

    • A replacement motherboard for an Intel Core i5-10600K processor must have an LGA 1200 CPU socket for compatibility.

    Extensible Firmware Technology

    • UEFI (Unified Extensible Firmware Interface) supersedes BIOS, providing improved startup configurations and options.

    Power Button Functions

    • The power button feature allows multiple functions: booting up, hibernating, resuming, and shutting down with different pressing durations.

    Performing System Checks

    • To execute a series of system checks across BIOS/UEFI and additional components, ensure access to the POST process during startup.

    Clearing Boot Passwords

    • The motherboard jumper or CMOS reset can return a computer to a state allowing it to boot without a password, designed for emergencies.

    Signal Pathways

    • The Front-Side Bus (FSB) is the set of signal pathways between the CPU and external cache memory.

    Chipset Functionality

    • Chipsets manage data flow between the CPU, memory, and peripherals, influencing overall system performance.

    Gaining BIOS/UEFI Access

    • A motherboard's jumper reset typically allows gaining access to BIOS/UEFI configuration when an unknown password is present.

    Soft Restart Feature

    • The "soft reset" feature enables a complete restart of the computer without fully cutting the power.

    TPM and BitLocker Use

    • Trusted Platform Module (TPM) is utilized by Microsoft's BitLocker for encryption and secure boot processes, enhancing data protection.

    CPU Cooling Solutions

    • For a four-pin CPU fan connector and a three-pin header on the motherboard, using a suitable adapter or fan control method can ensure adequate cooling.

    Common Motherboard Components

    • Common components found on a motherboard include the Northbridge and Southbridge chipsets, which manage communication between the CPU, RAM, and peripheral connections.
