    Study Notes

    Computer Networks

    • A computer network is a group of interconnected devices that can share resources, data, and information.

    Features of a Computer Network

    • Resource Sharing: Networks allow users to share hardware, software, and data.
    • Communication: Enables communication between users, such as email, instant messaging, and video conferencing.
    • Centralized Management: Networks provide a central point for managing and controlling network resources.
    • Improved Efficiency: Networking enhances productivity by streamlining tasks and automating processes.

    Types of Networks

    • Local Area Network (LAN): Connects devices within a small geographical area, such as an office or home, typically using Ethernet cabling.
    • Wide Area Network (WAN): Spans a large geographical area, connecting multiple locations, often using leased lines or public networks.
    • Metropolitan Area Network (MAN): Covers a city or metropolitan area, connecting multiple LANs within a city.
    • Personal Area Network (PAN): Connects devices within a limited range, typically used for personal devices like mobile phones, laptops, and Bluetooth headsets.

    Wireless Personal Area Network

    • Bluetooth: A short-range wireless technology used for connecting devices like headphones, speakers, and smart home appliances.

    Data Transfer Rate

    • Fiber Optic Cables: Fiber optic cables transmit data at extremely high speeds compared to traditional copper cables.

    Network Advantages

    • Shared Resources: Allows users to access shared printers, scanners, and other resources.
    • Centralized Data Storage: Enables data to be stored in a central location, making it accessible to multiple users.
    • Improved Communication: Facilitates efficient communication between users, teams, and organizations.
    • Cost-Effective: Networks can reduce costs by sharing resources and eliminating redundant purchases.
