If you are browsing this content or checking your email or working on a standalone laptop but sent a document to print, networks & communication in all these instances are at play. This is how dependent our modern civilization is on networks & communication systems.
Advanced Networks & Communication systems look like the human nervous system transmitting digital data between two or more computers or a computer network comprising hardware and software connected, whether in the same geographical location or globally to facilitate communication and information sharing.
