Like peeling an onion, you will cry when you go through the layers!
Each layer has its own functionality and the interfaces between adjacent layers. It would be necessary to construct and interpret these in-coming and out-going requests to accept and pass onto the next layer, and hence adding some storage and processing time to the request - less efficient.

It doesn't. Programmers might use any approach they like.
Principles are not advantages or disadvantages of the layered approach, principles are behind the layered approachPrinciples:Data transmission error free.Minimum time for route discovery.Communication between layers through primitives.Congestion control for minimum delays and retransmission.Minimum effort in replacing new layer in the existing network layers.

What are the advantages and disadvatages of the humanistc approach?

The modular kernel approach requires subsystems to interact with each other through carefully constructed interfaces that are typically narrow (in terms of the functionality that is exposed to external modules). The layered kernel approach is similar in that respect. However, the layered kernel imposes a strict ordering of subsystems such that subsystems at the lower layers are not allowed to invoke operations corresponding to the upper layer subsystems. There are no such restrictions in the modular kernel approach, wherein modules are free to invoke each other without any constraints.
The following are the disadvantages of a layered architecture:There might be a negative impact on the performance as we have the extra overhead of passing through layers instead of calling a component directly.Development of user-intensive applications can sometime take longer if the layering prevents the use of user interface components that directly interact with the database.The use of layers helps to control and encapsulate the complexity of large applications, but adds complexity to simple applications.Changes to lower level interfaces tend to percolate to higher levels, especially if the relaxed layered approach is used.

The income approach to measure national income in the country of Ghana is not very accurate. Much of the Ghana economy relies on the barter system.

Setting out the research approach Conducting a review of the literature Using a systematic approach to the literature review Nature of research - databases that were searched Advantages and disadvantages of desk-based research
Disadvantages of system approach that it is rigid, if there is any change in the environment, it will react quite slow and this approach is good for manufacturing industry but not service industry which require to adopt to the external environment.
