主机 A 向主机 B 发送一个(SYN=1,seq=11220)的 TCP 报文,期望与主机 B 建立 TCP 连接,若主机 B 收到接受该连接请求,则主机 B 向主机 A 发送正确的 TCP 报文段可能是( ) A: (SYN=0,ACK=0,seq=11221,ack=11221) B: (SYN=1,ACK=1,seq=11220,ack=11220) C: (SYN=1,ACK=1,seq=11221,ack=11221) D: (SYN=0,ACK=0,seq=11220,ack=11220)

A system has four processes and five allocatable resources. The current allocation and maximum needs are as follows: Allocated Maximum more Available ProcessA 10211 11213 01002 00x11 ProcessB 20110 22210 02100 ProcessC 11010 21310 10300 ProcessD 11110 11221 00111 What is the smallest value of x for which this is a safe state?
