What are the different Networking devices.


There are three main networking devices hub,switch, router.

1. Hub is layer one device in OSI Model.
2. Switch is layer  two device in OSI Model.
3. Router is  layer device three  in OSI Model.

  •  Application layer
  •  Presentation layer
  •  Session layer
  •  Transport layer
  •  Network layer(Router)
  •  Data link lyer(Switch)
  •  Physical layer(Hub)

What are the different Networking devices.


Networking devices includes:

NIC (Network Interface Card) -an expansion card attached to a computer motherboard the connects network medium to the computer bus.

Hub -a device that connects all segments of a network together.

Router – a device that connects dissimilar network segments into one and selects path data travels through each network segment.

Switch – Similar to a hub but does not rebroadcast message to all computers in network but between the sender and receiver.

The OSI model is made up of seven layers; each layer with some associated protocols. The OSI model is only a logical model and provides guidelines of how network should be implemented. The layers are;

  • Application Layer-Defines a set of tools that application use to perform a task<responsible for how network services interact.
  • Presentation layer-responsible for all data operation ,that is data  formatting and data compression.
  • Session layer-responsible for creating  a connection between two computer called sessions, where they are synchronized performs security authentication.
  • Transport layer –ensures error free transmission of data ,  structures  messages and checks their validity.
  • Network layer-responsible for Logical addressing/IP addressing and routing ensuring data arrives at the correct location.
  • Data Link layer-Responsible for MAC addressing and Logical Link control i. e. (defines logical network topologies).
  • Physical layer-Responsible for specification of Physical Topologies and translation of data into signals that can be transmitted over a transmission medium e. g. copper or fiber.

What are the different Networking devices.


Modems -meaning  MODULATION  DEMODULATION, is a network device that changes data from  a digital form into analog form and from an analog form into digital for transmission over an appropriate communication medium.

Gateways, a  combination  of hardware and software that connects dissimilar network environments.

MAU (Multi station Access Unit) – Has similar functionality to that of  a hub but used in the Token Ring Network type.  It creates data paths that form  the ring in a token network.

Router – Combines the functionality of a router and that of a bridge, found on the Network layer although it’s not used nowadays.

Here is the solution.

On the client computer running Serial/IP.

  •   You add virtual COM ports using the Serial/IP Control Panel and configure them to use your serial server.
  •   Your application uses Serial/IP virtual COM ports instead of local physical COM ports.
  •   Your application opens, reads and writes virtual COM ports using the standard COM port API.
  •   The Serial/IP Redirector automatically makes TCP/IP connections to the serial server and relays the virtual COM port data stream and control actions.

At the remote location

  •   The serial server accepts connections from Serial/IP, then converts and relays the data stream and control signals to the server's serial ports.
  •   Wireless modems can be used instead of serial servers.
  •   The field equipment gets the data stream through serial cables or direct here.
