Which of the following is/are the applications of Asynchronous Transfer Mode (ATM)?

Which of the following is/are the applications of Asynchronous Transfer Mode (ATM)? Correct Answer All of the options

ATM reference model comprises of three layers

Physical Layer

In this layer, the cells are converted into bitstreams and transmitted over the physical medium. This layer has two sub-layers: PMD sublayer (Physical Medium Dependent) and TC (Transmission Convergence) sublayer.

ATM Layer

It accepts the 48-byte segments from the upper layer, adds a 5-byte header to each segment, and converts into 53-byte cells. This layer is responsible for routing of each cell, traffic management, multiplexing and switching.

ATM Adaptation Layer

It provides facilities to the existing packet-switched networks to connect to the ATM network and use its services. It accepts the data and converts them into fixed-sized segments. This layer has two sub-layers − Convergence sub-layer and Segmentation and Reassembly sub-layer.

ATM Applications:

  • ATM WANs
  • Multimedia virtual private networks
  • Frame relay backbone
  • Residential broadband networks
  • Carrier infrastructure for telephone and private line networks 

Therefore All of the options is the answer

A Windows 2000 Server computer named server2 runs numerous 32bit applications and two 16bit applications. Users start the 16bit applications by running APP1.EXE for one application and APP2.EXE for another application. The 16bit applications are configured to run in the separate memory space. You want to create a performance base like chart in the system monitor for all the applications on server2. You add all of 32bit applications and now you want to add two 16bit applications. What should you do?

In a wetted-wall tower, an air-H2S mixture is flowing by a film of water which is flowing as a thin film down a vertical plate. The H2S is being absorbed from the air to the water at a total pressure of 1.50 atm abs and 30oC. The value of kc of 9.567×10-4 m/s has been predicted for the gas-phase mass-transfer coefficient. At a given point the mole fraction of H2S in the liquid at the liquid-gas interface is 2.0×10-5 and pA of H2S in the gas is 0.05 atm. The Henry’s law equilibrium relation is pA(atm) = 609xA (mole fraction in liquid). Calculate the rate of absorption of H2S.
