Data communication refers to the exchange of digital information between devices via wired/wireless channels, while networking involves connecting these devices (like computers, servers, routers) to share resources. 

DCN is the backbone of modern IT systems. It’s used for:

  • Internet & cloud services: streaming, emails, browsing
  • Business operations: secure file sharing, remote work setups
  • IoT & smart devices: connected homes, industrial sensors
  • Cybersecurity: protecting data with firewalls, encryption

This data communication and networking course is perfect for: 

  • Beginners curious about how networks function.
  • IT professionals upgrading skills (network admins, security analysts).
  • Students prepping for certifications (CCNA, CompTIA Network+).
  • Career switchers aiming for roles in networking or cybersecurity.
