Digital communications systems
A digital communication system consists of different devices linked together to transmit and receive data through signals and various transmission media.
NETWORK SCOPES
PAN (Personal Area Network) A PAN operates within a very short range, usually a few meters. It is used to connect personal devices like smartphones, headphones, USB devices, Bluetooth, or NFC.
LAN (Local Area Network) A LAN covers a limited area such as a house, school, or office building. It commonly uses Wi-Fi or Ethernet and provides fast data transfer.
MAN (Metropolitan Area Network) A MAN links several local networks across a city or large area, such as a university campus or group of buildings.
WAN (Wide Area Network) A WAN connects networks over large distances, even between countries or continents. The Internet is the most common example.
GAN (Global Area Network) A GAN connects networks worldwide using advanced infrastructure like fiber optics and satellites, offering global coverage.
NETWORK TOPOLOGIES
Bus Topology Devices connected to one main cable. Used in small or old offices. Ring Topology Devices connected in a circle. Used in legacy networks. Star Topology All devices connect to a central router. Used in home Wi-Fi networks.
TRANSMISSION MEDIA
Transmission media is the path data uses to travel between devices
Fiber Optics Light signals. Very fast and long distance.
Coaxial Cable Cable TV type cable. Used for internet and TV.
Twisted Pair Copper cables (Ethernet). Used in homes and offices.
VHF / UHF Radio frequencies. Used for TV and radio signals.
Microwaves High-frequency wireless. Used for satellite communication.
NETWORK DEVICES
Laptop User device for work and study
Smart Car Connected vehicle (GPS, internet)
IP Phone Makes calls using the internet
Smart Speaker Voice assistant connected to Wi-Fi
Smart House Many IoT devices connected together
