Which of the following layers of the OSI model does not provide any service to any other OSI layer? Correct Answer Physical layer

Physical layer:

  • It is concerned with transmitting raw bits over a communication channel
  • The physical layer is the only layer of the OSI network model which actually deals with the physical connectivity of two different stations.
  • This layer defines the hardware equipment, cabling, wiring, frequencies, pulses used to represent binary signals etc.
  • Physical layer of the OSI model does not provide any service to any other OSI layer

The Weberian model of bureaucracy has been criticised from a variety of stand points.
Consider the following points in this regard:
1. The Weberian model appears to be a 'machine theory' and a closed system model taking little account of organisational interactions with the environment.
2. The structural features of bureaucracy as laid down by Weber might be suitable for routine and repetitive tasks but these would produce dysfunctional consequences in terms of human behaviour if the jobs would involve innovation and creativity.
3. Weberian model has not been found to respond adequately to the tasks of socioeconomic transformation in the developing countries. These tasks require quick changes whereas the capacity of the Weberian model for adaptation to change is rather slow.
4. Weber's model is confined to the study of formal bureaucratic structure and fails to take notice of the informal structure of bureauracy such as informal relations, informal norms and values, an informal power hierarchy and informal power struggles.
Which of the above points make a valid criticism of the Weberian model? Select the correct answer from below:
