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.

Network is defined as a group of autonomous systems that are connected to each other. Computers in a network can communicate with each other.
Peer-to-peer
Computers that are connected to each other create a network. These networks are often configured with "public" internet Protocol (IP) addresses -- that is, the devices on the network are "visible" to devices outside the network (from the Internet or another network). Networks can also be configured as "private" -- meaning that devices outside the network cannot "see" or communicate directly to them.

Yes, all devices on a network must have a unique IP address or you will have an IP conflict and one of the devices will have its network connection disabled.
double-ring
network
Devices on a linear bus network are connected to each other via a wire, usually through a T-connector device. In effect, the devices are "daisy chained" together without any other device connecting them.
computer hardware
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.
