Description: his a sequence of bits, of which the first and last are
1. This sequence is used with the bits of the message to calculate
a check sequence which has 1 fewer bits than the generator. The
check sequence is appended to the original message. At the receiver,
the same calculation is performed on the message and check sequence combined.
If the result is 0 no transmission error is assumed to have occurred.

Description: 银行家算法是从当前状态出发,逐个按安全序列检查各客户中谁能完成其工作,然后假定其完成工作且归还全部贷款,再进而检查下一个能完成工作的客户。如果所有客户都能完成工作,则找到一个安全序列,银行家才是安全的。
♦ 与预防死锁的几种方法相比较,限制条件少,资源利用程度提高了。
-Banker s algorithm is a departure from the current state, one by one according to the security check sequence customers who can complete its work, and then assumed that the completion of its work and the return of all loans, and then to check a customer to complete the work. If all customers will be able to complete the work, then find a safe sequence, bankers are safe.

Description: 使用VC++实现循环冗余检验CRC检错,用二进制的模2运算,相当于在M后面添加n个0。得到的(k+n)位的数除以收发双方事先商定的长度为(n+1)位的除数P,得出商是Q而余数是R(n位,比P少一位)。例如M=101001(即k=6),除数P=1101(即n=3),经模2除法运算的结果是:商Q=110101,而余数R=001,这里的商并没有什么用处,而余数R作为冗余码拼接在数据M的后面发送出去。这种为了进行检错而添加的冗余码常称为帧检验序列FCS(Frame Check Sequence)。因此加上FSC后发送的帧为101001001,共有(k+n)位。
CRC是一种检错方法,而FCS是添加在数据后面的冗余码。
