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.
The basic hardware building blocks to interconnect network nodes include network interface cards (NICs) for connecting devices to the network, switches for connecting multiple devices within a local network, routers for managing traffic between different networks, and cables or wireless connections for transmitting data between nodes.

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.
Router
An RJ-45 jack is primarily used for connecting Ethernet cables, which facilitate wired network connections for computers, routers, switches, and other networking devices. It can also be connected to VoIP phones and certain types of security cameras that utilize Ethernet for data transmission. Additionally, some devices may use RJ-45 jacks for connecting to network-enabled printers and smart home devices.

The meaning of Computer network is focusing on sharing data and peripheral devices like printer, scanner, and other devices.
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.
