→ LUCENE:感謝 原來protocol指的是這個 11/28 12:27
※ 引述《LUCENE (LUCENE)》之銘言：
: Compare and explain the difference between these two storage mechanisms:
: Cache and Vitual memory, according to their storage type, size, latency,
: protocol, hit ratio, and others.
: I don't get what protocol is in this comparison.....
: Someone knows that answer?
: Thanks a lot. strategies
