1. queue is a useful structure
* what is a queue?
* write 5 operations or s, without details, that can be done on a queue.
2. insert a sequence fo keys(24,49,13,20,59,23,90,35) into a data structure, which has no keys initially. depict the data structure after these insertions, if it is:
* a heap tree
* an avl tree
3. * what is a synchronous i/o bus?
* what is an asnchronous i/o bus?
* compare the advantages and disadvantages of synchronous and a synchronous i/o bus.
4. explain the following terminology:
* baud rate
* handshaking
* memory mapped i/o
5. explain the key issues in supporting a real-time operation system for embedded system.
6. explain the mapping of visual addresses to real addresses under paging by
* direct mapping
* associative mapping
* combined direct/associated mapping
7. please explain what is “write-back” and “write-through”, and discuss the advantage and disadvantage about these two methods.
8. explain the concept and benefit of threads
9. what is hardware interrupt? what is software interrupt? what is exception? please tell me all you know about interrupt.
10. write a recursive that tests wether a string is a palindrome. a palindrome is s string such as “abcba” or “otto” that reads the same in both you can write this recursively,you can write an iterative version of this instead.
