That would be the network card or modem.
You should suspect problems with the local network if the users are having similar problems, but they are located in different places. The network would be common to them and therefore the source of their problem.
Telnet can be used to get into certain routers and other devices in the network. This will aid in the troubleshooting process because the devices support that protocol but it should be noted that it is a very insecure protocol and should never be used from outside the network to the inside of the network.
An example would be a SSP (SuperSandPorpoise)
A group of computers and devices interface and communicate with each other. These devices are constantly sending and receiving data from each other. Depending on which type of network you are referring to, there are different guidelines the devices must adhere to. For more information on the specifics of different networks, I would recommend checking out Wikipedia (wikipedia.org/wiki/Computer_network)

If I am reading your question correctly, I would imagine it is because the computer is not on the same network... **The computer has an invalid default gateway address**

over the network
That would depend on the network topology chosen and the type of network connectivity devices employed. In a properly constructed, switched and/or routed network the answer would be NO. If hubs or repeaters are used to connect devices and/or network segments, then yes. In a bus or ring topology, the answer is yes. Whether anything is done with the frame is a different matter and depends on whether you consider the network adaptor to be integral to the computer.
Topology is the actual layout of the network, for instance, where the routers and other devices are located. That would be the networks topology.
A MAC (Media Access Control) ID is essential for identifying devices on a network. It ensures that data packets are sent to the correct device within a local network by providing a unique identifier for each network interface. This helps in managing network traffic, improving security, and facilitating communication between devices. Without MAC IDs, devices would struggle to distinguish between each other, leading to potential data loss and network inefficiencies.
