A magnetic circuit consists of silicon steel of 3000 permeability, of 10 cm length and a 2

cm air gap. Both have the same cross section of 1.5 cm. A current of 0.5 A is needed to

flow through the coil in order to produce a flux of 2351 Mx. Find the number of turns in

the coil.

Compare and contrast the medium access protocols and elaborate any one of them

Error control and Flow control is critical in effective frame transfer in a data link layer. Discuss the types of errors in detail and suggest suitable solutions for the same

Elaborate in detail the transition strategies from the IPv4 to the IPv6 with the help of a suitable example 

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 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.
