    Study Notes

    Introduction to Networks

    • We live in a network-driven world.
    • Networks are complex, connecting a wide range of devices.
    • Network infrastructure includes three main components: devices, media, and services.

    Network Components:

    • End devices are the source and destination of messages.
    • Intermediary devices connect end devices and manage data flow within the network.
    • Network media facilitates communication between devices, including metallic cables, fiber optic cables, and wireless transmission.

    Reliable Network

    • Two key aspects of network security are:
      • Network infrastructure security
      • Information security
    • The goals of network security are:
      • Confidentiality: ensuring only intended recipients can access data.
      • Integrity: ensuring data remains unaltered during transmission.
      • Availability: ensuring authorized users have timely and reliable access to data.

    Changing Network Environment

    • Networks adapt to new technologies and devices.
    • Key networking trends impacting businesses and consumers include:
      • Bring Your Own Device (BYOD): Allowing employees to use personal devices for work.
      • Online collaboration: Enabling teamwork and project management over the network.
      • Video communications: facilitating real-time video calls and conferencing.
      • Cloud computing: Providing access to data and services and applications over the internet.

    Cloud Computing

    • Cloud computing offers three main types:
      • Public clouds: Services available to the general public via pay-per-use models or for free.
      • Private clouds: Services reserved for specific organizations or entities.
      • Hybrid clouds integrate elements from different cloud types.
    • Smart home technology integrates network connectivity into everyday appliances.
    • Powerline networking allows devices to connect to LANs using existing electrical outlets.
    • Wireless broadband provides internet connectivity using cellular technology similar to smartphones.
