Describe how one can adjust the address lines, data

lines, if 4096 bytes of RAM is required by a system.

The lowest chip size is 256*8.

Give complet diagrams.[5 marks]

An extra address space is accocated by the operating 

system to easily run applications . Elaborate on this 

with proper method and strategy of page swapping.[10 marks]

what principles are preferred to bring data into coche,

so that low amount of miss ration is observed ? [5 marks ]

In this method while sending the data towards destination 

a proper method of accepting the data packet is performed.

so, the source knows that data has been revived. Elaborate 

with diagrams and example. [10 marks]

A prop shaft of a heavy-duty truck has two bearings which are positioned at 3 metres from each other. The shaft must rotate at 30 rad/s when the truck travels at the speed of 40 m/s. Such a shaft carries two masses of (MA = 10 kg) and (MB = 5 kg) acting at the extremities of the arms 0.45 m and 0.6 m long, respectively. The planes in which these masses rotate are 1.2 m and 2.4 m,

respectively, from the left end bearing supporting the shaft. The angle between the arms is 60°. If the masses are balanced by two counter-masses (named X and Y) rotating with the shaft acting at a radius of 0.3 m and placed at 0.3 m from each bearing centre:

• Draw a diagram illustrating the position of masses on the shaft.
• Calculate the dynamic force in Newtons. Tabulate the results.
• Calculate the moment acting on the shaft in Newton-metre. Tabulate the results.
• Determine the magnitude of the Y balance mass using a vector diagram.
• Determine the magnitude of the X balance mass using a vector diagram.

An inward flow reaction turbine is required to produce a power of 280 kW at 200

rpm. The effective head on the turbine is 20 m. The inlet diameter is twice as the

outlet diameter. Assume hydraulic efficiency as 80%. The radial

velocity is 3.5 m/s and is constant. The ratio of breadth to wheel diameter is 0.1

and 5% of the flow area is blocked by vane thickness. Determine the inlet and

outlet diameters, inlet and exit vane angle and guide blade angle at the inlet.

Assume radial discharge.

24. Pick 5 numbers and compute the population standard deviationof the numbers

a. Add a nonzero constant c to each of your original numbers, and compute the standard deviation of this new population.

b. Use the results of part a and inductive reasoning to state what happens to the standard deviation of a population when a nonzero constant c is added to each data item.

25. Pick 6 numbers and compute the population standard deviation of the numbers

a. Double each of your original numbers and compute the standard deviation of this new population

b. Use the results of part a and inductive reasoning to state what happens to the standard deviation of a population when each data item is multiplied by a positive constant k.
