Static routing algorithm is a form of routing which occurs when a router uses a manual configuration routing entry rather than dynamic entry.In different cases, static routes are manually configured by a network administrator by adding entries into the routing table. It is not possible in all cases. Static routes ... Read More

Transmission impairment occurs when the received signal is different from the transmitted signal. As we know, a signal can be transmitted as Analog signal or it can be transmitted as a digital signal.In Analog signals due to transmission impairment the resulting received signal gets different amplitude or the shape. In ... Read More

The real function of every layer in OSI is to provide services to the layer above it.Network Services TerminologyThe network services terminology is explained below −Entities − In each layer there are so many active elements. An entity can be a software entity or a hardware entity. For example, a ... Read More

ISDN is also known as Integrated Services Digital Network. It is helpful in a wide range of services, for example, text (message), image, etc. It is capable of giving services and the foundation of telecommunication networks i.e. useful in the framework.It was also known as Integrated Digital Network because it ...

The physical layer’s major function is to move data in the form of electromagnetic signals over a transmission medium. The data which is used by a person is not in a form that can be transmitted over a network.For example, a photograph has to be changed to a form that ... Read More

Dense wavelength division multiplexing (DWDM) is a technology that multiplexes data signals from different sources so they can share a single optical fibre pair while maintaining complete separation of the data streams.DWDM can handle higher speed protocols up to 100 Gbps per channel. Each channel is only 0.8nm apart. Dense ... Read More

Let us understand what a SONET/SDH Transmission in computer networking is.SONET/SDH TransmissionSONET stands for synchronous optical network. It offers cost effective transport both in the access area and core of the network.The transport services for the metro are provided by the optical layer. The optical layer has been now giving ...

Access Network is a type of network which connects the end system to the immediate router, physically in the path from the end system to any other distant end system. In telecommunications it is the network connecting subscribers to ISP.Some of the examples of the Access Networks are as follows ... Read More
