[理工] [OS]-Critical section and 衝突?
在看考古題看到一題是關於臨界區域的，不知如何寫比較好，希望大家可以討論一下。
1. Why we have to guard against race condition and synchronize the critical
section?
2. please justify whether the following two concurrent serizalizable
transaction To and T1 , schedule S can be transformed into a serial schedule
S1.
To T1
read(A)
write(A)
read(B)
write(B)
read(B)
write(B)
read(B)
write(B)
第一題不知要如何回答比較好?
第二題，知道To read(b)和T1 write(b)衝突
To write(b)和T1 read(b)衝突
To write(A)和read(b)沒衝突
但是答案只要寫這個就好嗎?謝謝。
