SUN MICRO SYS

SUN 1.struct XXX { int a; float b; char *s; }X; If optimization :X not used in compiler then un used bits_________________. give your assumption_______________. 2.struct XXX { int a:6; float b:4; char s; }structure; size og (structure); 3.class used for the multiple inheritence in yava_________________ (a) Anonymous class (b) inner class (c) abstreet class (d) none 4. XDR fixes in which part of OS1 stack. 5. LDAP is____________service protocol. 6. Given definition for a function which returns a array of pointers with argument of int*. 7.Give a function declaration with no arguments which refers a two dimensional array 8.Pick up the correct function declaration. 1.void *[] name(); 2 void int[][] name(); 3 void ** name(); 4 none of the above. 9.Give the difference between monolithic and microlithic kernal: a mololic large b micro used in embedded systems. c.none. 10.rPC coresponds to_______________in OSI stack. 11.find the no.of page faults using LRU stack. eg.3 4 4 6 7 8 1 2 .. .. 12.the inorder representation of a tree 41523 and preorder is 211513 Draw it? 13. when does a stack member will be initialised (a) when object is created (b) when object is initialised. (c) doesnot depend on object. (d) none. 14 no.of CPU in a multiprocess is contrassed by (a) RISC nohere of CPU (b) memory (c)___________ (d)_____________ 15 main() { char *s; s="hot java"; strcpy(s,"solarrs java") } 16 main() { printf("hot java"); fork() exit(0); } 1. when redirected to a sreen what will be printed. 2 when redirected to file what will be printed. 17.main() { int ret; ret=fork();ret=fork();ret=fork();ret=fork(); if(!ret) printf("sun"); else printf("solaris"); how many sun 4 solaris will get printed 18. main() { char *p='a'; int *i=100/*p; } what will be the value of *i= 1 1.03 cannot be defined. 19 which data structure gives efficient search 1 B-tree 2 binary tree 3 array 4 linked list 20. struct point { struct point *next; int data; }x; main() { int i; for(x=p;x!=0;) x=x->next,x++; freelist(x); } freelist(x) { free(x); return } find error? 21. mutex and _________are similar locking mechanisms. 22.nextt question on from pointers and functions( highfy) take care. 23. SNMP and SMIP transport layer protocols for TCP/IP&OSI. 24 unix : difference between select and poll interview questions were mainly on data structures, computer architecture ( very imp) , os and networks
