    Study Notes

    مكونات جهاز الحاسب الآلي

    الذاكرة الرئيسية (Main Memory)

    • Temporary storage for data and program instructions
    • Also known as RAM (Random Access Memory)
    • Data is lost when the computer is powered off
    • Measured in bytes (e.g. KB, MB, GB)
    • The more memory, the more applications can run simultaneously
    • Types of RAM:
      • SRAM (Static RAM): faster and more expensive
      • DRAM (Dynamic RAM): slower and less expensive

    اللوحة الأم (Motherboard)

    • The main circuit board of the computer
    • Connects and supports all hardware components
    • Components:
      • CPU socket
      • RAM slots
      • Expansion slots (e.g. PCI, PCIe)
      • Storage connectors (e.g. SATA, IDE)
      • Power connectors
      • Chipset: manages data flow between components
    • Functions:
      • Provides a platform for components to communicate
      • Regulates power supply to components
      • Manages data transfer between components

    القرص الصلب (Hard Disk Drive)

    • A non-volatile storage device for data and programs
    • Data is retained even when the computer is powered off
    • Measured in bytes (e.g. GB, TB)
    • Components:
      • Platters: spinning disks that store data
      • Read/write head: accesses data on platters
      • Actuator arm: moves read/write head
      • Motor: spins platters
    • Types of HDD:
      • IDE (Integrated Drive Electronics)
      • SATA (Serial Advanced Technology Attachment)
      • SCSI (Small Computer System Interface)
