3. Explanation:
ReplyDelete• htons(): reorder the bytes of a 16-bit unsigned value from processor order to network order. The macro name can be read "host to network short."
• htonl(): reorder the bytes of a 32-bit unsigned value from processor order to network order. The macro name can be read "host to network long."
• ntohs(): reorder the bytes of a 16-bit unsigned value from network order to processor order. The macro name can be read "network to host short."
• ntohl(): reorder the bytes of a 32-bit unsigned value from network order to processor order. The macro name can be read "network to host long."
10. Explanation:
ReplyDeleteNP means Non-deterministic Polynomial time and P means deterministic Polynomial time.
17. Explanation:
ReplyDeleteIn the child process, the return value of fork() is 0, whereas the return value in the parent process is the PID of the newly created child process.
