    Study Notes

    An ordinateur is a type of computer system designed for various uses, including home computing, office work, entertainment, and more advanced tasks like scientific computations. It consists of several key components that allow it to function effectively:

    Processeur

    The most important part of any computer system is its processor, commonly known as the CPU (Central Processing Unit) or microprocessor. This component executes instructions from programs by performing arithmetic operations or logical decisions. It's often described using clock speed; higher values indicate faster processing power.

    Mémoire RAM

    RAM (Random Access Memory) stores data temporarily so the CPU can access it quickly when needed. Larger amounts of memory enable multitasking—running multiple applications simultaneously without slowing down performance—and also allows you to open larger files with ease.

    Carte Graphique

    A graphics card helps render images onto your screen. If you play video games or edit photos/videos regularly, having a good one will significantly improve visual quality.

    Disque Dur

    This component holds all nonvolatile storage data such as documents, music and movies. Quite simply, this is where everything goes that won’t go into your computer’s RAM while it's being used.

    Carte Mère

    At the heart of every desktop PC or laptop, there lies a motherboard. All other components plug directly into this circuit board, which means it serves as the backbone of the entire device.

    Together, these five elements make up what we know today as 'the PC', capable of running almost anything software has to offer.
