An organization is granted a block of addresses with the beginning address 150.25.0.0/24. The organization needs to have 3 subblocks of addresses to use in its three subnets: one subblock of 11 addresses, one subblock of 40 addresses, and one subblock of 125 addresses. Design the network and plot it completely with respective subnets, IP range, Network IDs

: Discuss the IPv4 Datagram with the help of suitable examples.

Compare the Go-back N protocol with the rest of the protocols for effective frame transmission in Data link Layer.

A chopped meat mixture is formed by blending lean meat &fat ingre each consisteing 0.12 gm partcle sizeto produce an overall fat content 15%. After 10min of mixing eight sample of 3 gm each were taken from mixing bowl. Each sample was measured for fat content which give foll. Results expressed as 17.9%,23.3%,10%,13.3%,16.7%,26.7%6.7%12.2%.The mixtures was formed after mixing 10min from initial seprate ingredients of fat nd lean meat each composed of 0.12gm partcle .

A ) What would be expected value of mixing index after 15 min.mixing ?

B) What will be expected variance after 15min of mix?

C)If u were developing a schedule for this processing step what would be the recommended total mixing time nd why?

. A wet steam at a pressure of 1.0 𝑀𝑃𝑎 has a quality of 85%.

i. Use thermodynamic steam tables to determine its entropy and specific volume.

ii. Use the Mollier chart to determine its enthalpy.

iii. For each of the results above, calculate the internal energy of the steam.

Determine the enthalpy of a saturated steam at 30𝑜 𝐶 using the non-flow energy equation

and the tabulated properties of pressure, specific volume and internal energy. Compare

the result with the tabulated value of ℎ𝑔.

A system uses DMA for data transfer from a magnetic disk to memory to

transfer 512 words to a memory section starting from address 1024. Give the

initial values that the CPU must transfer to the DMA controller to initiate

this transfer.

Consider a hypothetical computer which has five interrupt requests during

data transfer between CPU and I/O device. Write the procedure that machine

can establish interrupts in interrupt service routine. Explain how the interrupt

service routine will be executed without priority interrupt hardware.
