DCN – Data-link Control & Protocols
Data-link layer is responsible for implementation of point-to-point flow and error control mechanism. Flow Control When a data frame (Layer-2 data) is sent from one host to another over a…
DCN – Error Detection & Correction
There are many reasons such as noise, cross-talk etc., which may help data to get corrupted during transmission. The upper layers work on some generalized view of network architecture and…
Cold Start Smoke Problem with Volvo Penta Marine Engine
Marine Engine Volvo Penta marine engines have been around for some time and are still a popular choice for sailing boats and cruisers. They do however have inherent problems of…
DCN – Data-link Layer Introduction
Data Link Layer is second layer of OSI Layered Model. This layer is one of the most complicated layers and has complex functionalities and liabilities. Data link layer hides the…
DCN – Network Switching
Switching is process to forward packets coming in from one port to a port leading towards the destination. When data comes on a port it is called ingress, and when…
The Formation of Hydrocarbons in Offshore Reservoirs
The formation of hydrocarbons in offshore reservoirs occurred 300 million years ago being formed by decaying plankton and algae on the seabed. These were then covered in silt, sand and…
DCN – Multiplexing
Multiplexing is a technique by which different analog and digital streams of transmission can be simultaneously processed over a shared link. Multiplexing divides the high capacity medium into low capacity…
Main Engine Operating Troubles
Operational Faults - Engine Receives No Fuel to Start In marine diesel engine which are mainly started by air ,the highly compressed air is used to start the engine when…
DCN – Wireless Transmission
Wireless transmission is a form of unguided media. Wireless communication involves no physical link established between two or more devices, communicating wirelessly. Wireless signals are spread over in the air…
DCN – Transmission Media
The transmission media is nothing but the physical media over which communication takes place in computer networks. Magnetic Media One of the most convenient way to transfer data from one…
