What is the different type of networking / internetworking devices?
1. Repeater: Also known as a regenerator, it is an electronic device that operates only at physical layer. It gets the signal in the network before it becomes weak, regenerates the original bit pattern and gets the refreshed copy back in to the link.
2. Bridges: These function both in the physical and data link layers of LANs of similar type. They separate a larger network in to smaller segments. They contain logic that permit them to keep the traffic for every segment separate and thus are repeaters that relay a frame only the side of the segment having the intended recipient and control congestion.
3. Routers: They relay packets between multiple interconnected networks (i.e. LANs of dissimilar type). They operate in the physical, data link and network layers. They have software that enables them to verify which of the several possible paths the best for a particular transmission is.
4. Gateways: They relay packets between networks that have different protocols (e.g. among a LAN and a WAN). They accept a packet formatted for one protocol and change it to a packet formatted for another protocol before forwarding it. They operate in all seven layers of the OSI model.
NETWORK ANALYZERS: A network analyzer also known network monitor or a network sniffer is used to calculate the performance of or debug a network. It may report statistics s

Demarcation is the point in which responsibility changes hands.
An FDDI frame or Token Ring frames those points to serious problem with the ring, like a broken cable. The beacon frame carries the address of the station thought to be down.
Let us firstly illustrate the idea of merging two sorted sequences using a odd-even merging circuit. The functioning of a merging circuit is as follows: 1) Let there be two so
