This diagram offers an overview of how broadband networks are distributed and utilized. In this scenario, BSNL ILL (potentially referring to a regional broadband service provider) is the starting point, where users connect to this service via network access equipment and gain a range of internet access privileges. The splitter plays a crucial role here; it divides a single broadband signal into multiple streams heading to different terminals or devices. This allows for supporting simultaneous online demands of multiple users. Meanwhile, the firewall remains a key component of network security, shielding the network from malware, viruses, or other security threats.
