    Study Notes

    CPU Performance

    • The collection of commands a specific CPU can execute is called the instruction set for that system.
    • Pipelining is a technique that allows the CPU to work on more than one instruction at the same time.
    • The CPU consists of two parts: the control unit and the arithmetic logic unit (ALU).
    • The control unit is one component of the CPU.
    • The arithmetic logic unit (ALU) performs arithmetic calculations.

    CPU Design and Operation

    • The rule of thumb that predicts the number of transistors on a CPU will double every two years is called Moore's Law.
    • The processor market for desktop and laptop computers is dominated by Intel.
    • Clock speed, number of cores, and amount of cache memory influence a CPU's processing power.
    • The speed of the motherboard does not influence a CPU's processing power.

    RAM and Memory

    • RAM is an example of volatile storage.
    • The amount of RAM storage on modern computing devices is usually measured in gigabytes.
    • Windows uses a memory-management technique known as SuperFetch to monitor which applications you use most frequently and then preloads them into system memory.

    Storage and Hard Drives

    • The fastest, most expensive memory in your computer is registers.
    • When a hard drive has to wait for the correct sector to spin to the read/write head, the delay is known as latency.
    • Running the Disk Defragmenter utility will make the hard drive work more efficiently.

    Parallel Processing and Networking

    • When a large group of computers are networked to work together on a task, it is known as parallel processing.
    • Hyperthreading provides high-speed information processing by enabling a new set of instructions to start before the previous set is finished.

    Sound Cards and Utilities

    • 3D sound cards do not produce surround sound.
    • Running the Disk Cleanup utility is a quick way to clear out temporary Internet files.
    • The Windows Reset utility returns your computer to the state it was in when it came from the factory.
