One Interview Only (Technical + HR). Interview in front of panel of 2 persons. Tell me something about yourself. Your favorite subjects (I mentioned Computer Networks , Operating Systems , Algorithms, Data Structures ) Functions of Data Link Layer .Where is Data Link Layer present on computer? Layer 2 Devices. What is Ethernet?Ethernet is related to which layer in TCP/IP Model. How actual transmission is done using TCP/IP model. Host A want to communicate with Host B.Host A knows only its own MAC address.For communication,is it necessary to know MAC address of Host B?If yes,how will the MAC address of B will be found? (The question was linked to ARP protocol) Channel Allocation Problem. Asked about static,dynamic allocation techniques FDM,TDM,Aloha,CSMA/CD,CSMA/CA. Sliding window protocol .How error recovery is done at data link layer? Switch vs Hub . what happens when we type url .Asked about DNS. Asked about projects.(Technologies,platform used) Asked about Training. Which project is being carried on for Minor Project. C-output questions 1.extern int var; int main(void) { var = 10;

return 0; } 2.int main() { static int var = 5; printf("%d ",var--); if(var) main(); } Voaltile keyword in C. Memory Segments (Data,Code Segment). Size of heap and stack. What is stored on stack on function call. M ultithreading application .How two threads will communicate with each other. Mutex and semaphore . How to debug a program? Any debugging tool used ever?. ADVICE: Focus on Computer Networks,Operating Systems in great detail and be thorough with each and every details of project.
