No, a simple home network can be configured to share data and devices without connecting to the internet.
Computer network devices also known as communication devices and they constitute a data communication network. These devices are routers, switches, hubs, LAN cards, gateway, modems, hardware firewall, CSU/DSU, ISDN terminals and transceivers. In an Ethernet or WAN network, the data communication cannot be performed without these devices. Being an IT professional or a network administrator, you must have the good understanding of these devices.
Topology is the structure that describes how devices in a Network are connected.Bus Topology: Directly connects all devices to network i.e utilises a single Physical medium for Data transmission between devices.Star Topology: Connects all devices in network through a Central Network connecting device such as Hubs & Switches.Advantage of Bus Topology is that less connecting cable is used.Advantage of Star Topology is that Network can function in case one or more devices fail.Disadvantage of Bus Topology is that whole Network goes down if one device fails.Disadvantage of Star Topology is that it requires physical connecting medium from Central device to the connecting device i.e more expensive.

To share data using Ethernet, you need to connect the devices you wish to share data between to the same Ethernet network. Once connected, you can transfer data between devices by using network protocols such as TCP/IP. Sharing data over Ethernet can be done via file sharing, network drives, or direct communication between devices on the network.
The meaning of Computer network is focusing on sharing data and peripheral devices like printer, scanner, and other devices.
Global System for Mobile Communications, or GSM, originally described a digital circuit switched network using full duplex voice telephony. It has been upgraded to include data communications and packet transport.
