Which layer will come in between the transport layer and the data link layer in the OSI model? 

Which layer will come in between the transport layer and the data link layer in the OSI model?  Correct Answer Network layer 

The network layer layer comes in between the transport layer and the data link layer in the OSI model. The different layers associated with OSI are as shown:

 

Network Layer:

  • The network layer is responsible for ensuring data transfer between two different networks.
  • If the two devices communicating are on the same network, then the network layer is unnecessary.
  • The network layer breaks up segments from the transport layer into smaller units, called packets, on the sender’s device, and reassembling these packets on the receiving device.
  • The network layer also finds the best physical path for the data to reach its destination; this is known as routing.

Physical Layer: Responsible for the physical connection between devices.

Data-link layer: Responsible for reliable transfer of data frames from one node to another, connected by a physical layer.

Network layer: It manages the delivery of individual data packets from source to destination through Routing.

Transport layer: Responsible for the delivery of the center message from source host to a destination host. Here, Data is referred to as segments.

Session layer: It establishes sessions between users and offers services like dialog control and synchronization

Presentation layer: Monitors syntax and semantics of transmitted information through translation, compression, and encryption.

Application layer: Provides high-level application program Interface to user

Consider the following statement. I. Packet Filter Firewall analyze network traffic at transport layer. II. Circuit Level Firewall operate at transport and session layer of OSI Model. From the above statement which statement/s is/are True
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:
Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
Some small cubes of same height 7 cm but variable length and width are put inside a large cuboid of height 21 cm. Length and width of cuboid is 32 cm and 24 cm, respectively. Small cubes are put such that cubes at the bottom most layer is of similar base area; second layer contains all the cubes of similar base area and third layer have all the cubes of similar base area. Which of the following statement(s) given below is / are TRUE? A: If side of each small cubes at bottom most layer is 8 cm, then maximum number of small cubes that can be put at bottom most layer is 12. B: If maximum of 48 cubes can be put at second layer, then side of each cube at second layer is 6 cm. C: If side of each small cubes at third layer is 1.6 cm, then maximum number of small cubes that can be put at third layer is 300.

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: The government is working on a plan to set up a waterway freight corridor to connect the mainland with the northeastern states via Bangladesh at a cost of Rs 5,000 crore. The move would substantially reduce the time taken to transport goods to the eight northeastern states and costs.  Which of the following support the idea that the time of transportation will be reduced between the eight northeastern states? Arguments: I.The proposed 900-km waterway would be used to transport freight from the northern and eastern states to the northeast and would start near Haldia in West Bengal, go to the Sundarbans, merge into the Padma river in Bangladesh and then join up with the Brahmaputra in Assam.  II. Currently, highway connectivity to the northeastern states is patchy and transportation of goods by road entails a high cost and takes time. According to the ministry’s estimate, the waterway could help reduce the cost of transportation by about 70%.  III. The government is already developing a waterway along the Ganga river between Haldia and Allahabad (1,620 km) at a cost of Rs 4,500 crore. This link will also be utilised for trade between India and Bangladesh.
A 4-bar mechanism with all revolute pairs has link lengths lf = 20 mm, lin = 40 mm, lco = 50 mm and lout = 60 mm. The suffixes 'f', 'in', 'co' and 'out' denote the fixed link, the input link, the coupler and output link respectively. Which one of the following statements is true about the input and output links?
Consider the following three statements about link state and distance vector routing protocols, for a large network with 500 network nodes and 4000 links. [S1] The computational overhead in link state protocols is higher than in distance vector protocols. [S2] A distance vector protocol (with split horizon) avoids persistent routing loops, but not a link state protocol. [S3] After a topology change, a link state protocol will converge faster than a distance vector protocol. Which one of the following is correct about S1, S2, and S3?
