CDP is a Cisco proprietary protocol; it only works between Cisco devices. If CDP is enabled on a Cisco network device, it will regularly send frames with information about itself out its interfaces.CDP is a Cisco proprietary protocol; it only works between Cisco devices.

Network Computing Devices was created in 1987.
No. Frames are used on the data-link (layer 2) layer. Packets are used at the Network (layer 3) layer.
The whole point of the network layer, and layer 3 devices, is to move packets between separate networks. Layer 2 devices on the other hand (switches), only move frames using only the data link layer between hosts in that same network. Without layer 3 devices (routers or gateways), there could be no communication between separate interconnected groups of computers.
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
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.
In the context of computer networking, a frame is a data unit transmitted over a computer network. Frames are classified based on the protocol layer they belong to, such as data link layer frames (e.g., Ethernet frames), network layer frames (e.g., IP packets), and transport layer frames (e.g., TCP segments). Each type of frame serves a specific purpose in transmitting and delivering data across the network.
One device that is shared on the network is a router. This is the one that will connect the various devices to the shared network.
An ad-hoc network is a wireless network in which all connections are wireless. The only devices required are wireless network interface cards in all of the devices that want to participate in the network.
This is the definition of a computer network. Devices such as routers and bridges create logical network subnets and network domains that computers, printers, and other devices can connect with to join the network.
