the test consists of an aptitude part and a 
DESCRIPTIVE technical part. The aptitude test 
consisted of 40 ques to be answered in 20 minutes,,, 
the questions were like..... 

a certain number of old women had a meeting. they all 
brought their cats with them ..finally tere was a 
certain number of heads and a certain number of feet 
(sorry, i dont remember the numbers). how many old 
women were there at the meeting? 

simple series questions, pattern matching,picking odd 
man out ....tooo simple 

a question of men and work..(refer aggarwal) 

i dont think the aptitude test would be a problem. 
90% of the students went throu'. it was that simple. 

Regarding the tech section, tere was 2 options . one 
is software paper(which can be attempted by both 
computer and electronics students) and the vlsi paper( 
meant for electronics people only). 
the test was descriptive. following are some questions 
from the software paper which i remember. hope it will 
give u an idea of how the questions are gonna be. 

1.state kirchoffs law. 
2.truth table for XNOR. 
3.write the logical equation for a given truth table. 
4.draw the logical dig of a 2 to 1 multiplexer. 
5.expand PCI, USB, MDL, PNP......(so many..it would be 
better if u go throu the expansions of all acronyms 
related to the topic) 
6.a microprocessor has 20 address lines and 4 bit data 
line. how many single bit address locations are tere? 
7. given 16 bit address lines and a control line for 
read and write. how can u interface an 8k memory so 
that the initial address space of 8k if from that 
memory chip? 
8.write a macro in c to find the greater among two 
numbers. 
9.some simple c programs and to find out the 
error...like ill-matching if-else etc.. have a look at 
gets(), sprintf() and similar functions,,then 
pointers. 
10.to optimise the following assembly code..and write 
the final value of the registers. 
MOV CX,100H 
MOV DI,2000H 
MOV AX,0 
LABEL: MOV [DI],AX 
INC AX 
INC AX 
LOOP LABEL 
11. write a c program to copy a file to another. 
12. write an assembly program to clear the memories 
from 0x0000 to 0x0100. 
13. given a looong assembly program , write itz c 
equivalent...tooo complicated. i did not attempt it. 
14. explain semaphores, Mutex and spinlock 
15. wot do u mean by extern, static, volatile, 
register .... 
16. differntiate between EEPROM and FLASH memory. 
17.wotz the difference between SRAM and DRAM?
