Broadcasting is when a packet is sent to all hosts, or all hosts on a subnet. When a broadcast packet is sent through a typical ethernet switch, all port lights will flicker as that packet is forwarded out every port. Other packets are inspected for their intended destination and then forwarded out the correct port. Two very necessary and prevalent protocols, DHCP and ARP, rely on broadcasting. This means a typical ethernet router/gateway device relies on broadcasts. A device that does not rely on broadcasts is an ethernet NIC.
No, a simple home network can be configured to share data and devices without connecting to the internet.
There is no broadband connection on mobile devices. You can only use WiFi or Data connection over mobiles network.

The TCP FIN ACK is a crucial step in ending a connection between two network devices. It signifies that one device has finished sending data and is ready to close the connection, while the other device acknowledges this request. This exchange ensures that both devices are in sync and can safely terminate the connection without any data loss or errors.
Ethernet is a type of wired connection used for transferring data between devices on a network. It involves the use of cables to create a physical connection between devices.
The Digital Living Network Alliance (DLNA) involves data sharing service (media files). It uses a Wi-Fi connection network.

This is assuming that there is no outside access to the Ethernet network such as a Internet connection. If there were then firewalls would be needed to prevent a outside intrusion of the network. In addition to physical access security, a wireless network requires authentication and encryption to prevent unauthorized devices from connecting to the wireless network or capturing and decoding the data that is being transferred via a wireless network connection. If the wireless network has outside WAN access then you would also need firewalls as with the Ethernet network.
