Question 1

In a token ring network, the transmission speed is 10⁷ bps and the propagation speed is 200 metres/micro second. The 1-bit delay in this network is equivalent to:

Question 2

What is routing Algorithms used by OSPF routing protocol?

Question 3

Frames of 1000 bits are sent over a 10⁶ bps duplex link between two hosts. The propagation time is 25ms. Frames are to be transmitted into this link using Go back - N protocol.
What is the minimum number of bits (I) that will be required to represent the sequence numbers distinctly ? Assume that no time gap needs to be given between transmission of two frames.

Question 4

If the frame to be transmitted is 1101011011 and the CRC polynomial to be used for generating checksum is x⁴ + x + 1, then what is the transmitted frame?

Question 5

The Hamming distance between the octets of OxAA and 0x55 is

Question 6

If there are five routers and six networks in bet using link state routing, how many routing tables are there?

Question 7

In a system an RSA Algorithms with p = 5 and q = 11, is implemented for data security. What is the value of the decryption key if the value of the encryption key is 27?

Question 8

An email contains a textual birthday greeting, a picture of a cake, and a song. The order is not important. What is the content-type?

Question 9
