Queue is a useful structure

* What is a queue?

* Write 5 operations or functions, without details, that can be done on a queue.

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

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.

Explain the following terminology:

* Baud rate

* Handshaking

* Memory mapped I/O

Explain the key issues in supporting a real-time operation system for embedded system.

第6题：

Explain the mapping of visual addresses to real addresses under paging by

* direct mapping

* associative mapping

* combined direct/associated mapping

Please explain what is “write-back” and “write-through”, and discuss the advantage and disadvantage about these two methods.

第8题：

Explain the concept and benefit of threads

第9题：

What is hardware interrupt? What is software interrupt? What is exception? Please tell me all you know about interrupt

第10题：

Write a recursive function that tests wether a string is a palindrome. A palindrome is s string such as “abcba” or “otto” that reads the same in both directions. If you can write this function recursively,you can write an iterative version of this function instead.
