Communication Networks

Communication networks are systems that connect computers, devices, and people to share information and resources. They include infrastructures like cables, wireless signals, and servers that transmit data quickly and securely. Think of a network as a digital web that enables emails, internet browsing, phone calls, and data exchanges. The main types are local area networks (LANs), covering small areas like offices, and wide area networks (WANs), spanning larger regions. These networks rely on protocols—rules that ensure data is sent, received, and understood correctly—facilitating seamless, reliable communication across various devices and locations.
