S' 11 : 2 FN : AN 203 / AD 303 (1403)

COMPUTING AND INFORMATICS

Time : Three hours

Maximum Marks : 100

Answer any five questions, taking ANY TWO from Group A,

ANY TWO from Group B and ALL from Group C.

All parts of a question (a, b, etc) should be

answered at one place.

Answers should be brief and to the point and be supplemented

with neat sketches. Unnecessary long answers

my result in loss of marks.

Any missing or wrong data may be assumed suitably

giving proper justification.

Figures on the right hand side margin indicate full marks.
