WHAT ARE THE NETWORK DEVICES?

                     

1. HUB- A device used to connect the multi computers with the single device, and then performs like a single network.

2. SWITCH- Similar to a hub, but it keeps a record of the MAC addresses or the unique identity of the client devices connected to it.

3. ROUTER- is typically connected to at least two networks, commonly two Local Area Networks (LANs) or Wide Area Networks (WANs) or a LAN and its internet service Provider's network.

4. BRIDGE- is used to divide larger networks into smaller sections.

5. NETWORK INTER.FACE- is a device that enables computers to connect to the network

6. MODEM- is a device that converts the digital signals generated by a computer into a analog signals that can travel over conventional phone lines.

7. TRANSCEIVERS- is responsible for placing signals onto the network media and detecting incoming signals travelling through the same wire.

8. FIREWALL- is a networking device that can be either hardware or software-based.

WHAT IS NETWORK TOPOLOGY?

Network topology refers to the layout or structure of the network in relation with the flow of data.

Linear Bus Topology uses one long cable, referred to as backbone, to which computers and other devices are attached.

Star Topology uses central device called a hub with cables extending in all direction.

Ring Topology a type of network topology wherein nodes are connected to each other forming one contiguous pathway in a ring formation.

Mesh Topology originally conceived for military application, mesh networks are structures wherein all the nods on the network can route data traffic in their own.

Hybrid Topology as the name connotes, a hybrid topology is simply a network that uses a mix of any two or more different topologies is a such a way that final network does not exhibit one of the characteristics of the standard topologies.
