Network Devices and Communication Technologies Explained

  • The term "client" refers to devices connected to a network that users can utilize to access services from servers.
  • Networked devices, such as switches, access points, routers, and modems, interconnect servers and clients.
  • Access points, with antennas, enable devices like smartphones and laptops to connect wirelessly to a local area network.
  • Some devices function as access points, switches, and routers simultaneously, providing a three-in-one combo for interconnecting devices and routing traffic.
  • Switches act as junction points for data transmission between connected devices within a network.
  • Larger switches with 24 or 48 ports are organized in racks within data centers for efficient communication.
  • Routers interconnect different local area networks and can vary in size from small devices to large cabinets used by internet service providers.
  • Communication media includes wired options like Ethernet, coaxial, and fiber-optic cables, as well as wireless options like Wi-Fi, cellular networks, microwaves, and satellite communications.
  • Local area networks connect devices within a room or building, while backbone networks interconnect multiple buildings within a firm.
  • Metropolitan area networks extend connections across multiple branches within a city, while wide area networks interconnect operations globally for a single firm.
