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?
