Testimonial

Hi friends,
Today I am happy to convey you all that one of the readers of my blog http://www.netcomputerscience.in
has passed APSLET EXAM 2013.
This is what he said about his success:

"HAI, I AM  RAGHAVENDRARAO PAVULURI FROM ANDHRA PRADESH.

I MET YOU IN NETCOMPUTERSCIENCE.IN WEB SITE,I READ ALL THE

SUGGESTIONS THAT YOU GIVEN IN THAT.

I AM VERY THANKFUL TO YOU THOSE ARE ALL VALUEABLE TO ME.I HAVE JUST CLEAR APSLET EXAM 2013 .

UGC NET COMPUTER SCIENCE DECEMBER 2013 SOLVED PAPER 2 WITH EXPLANATION

1.  When data and acknowledgement are sent in the same frame, this is called as
(A) Piggy packing
(B) Piggy backing
(C) Back packing
(D) Good packing

Ans.: b.)

Piggybacking is a bi-directional data transmission technique in the network layer (OSI model).

Network question.

2. Encryption and Decryption is the responsibility of Layer.
(A) Physical
(B) Network
(C) Application
(D) Datalink

Ans.: c.)

Networking related.

Encryption is typically done at this level too, although it can be done on the application, session, transport, or network layers.

3. Using the RSA public key crypto system, if p = 13, q = 31 and d = 7, then the value of e is
(A) 101  (C) 105
(B) 103  (D) 107

Ans.: b.)

Network security and cryptography
