1.Improve access time and rate. Reduce the need for bandwidth. Caches solve the transfer problem by providing a buffer of intermediate speed between the components. If the fast device finds the data it needs in the cache, it need not wait for the slower devices. The data in the cache

1.Give two reasons why caches are useful. What problems do they solve? What problems do they cause? If a cache can be made as large as the device for which it is caching (for instance, a cache as large as a disk), why not make it that large and eliminate the device? Caches are useful du

1. Give two reasons why caches are useful. (1)There are only important information in the caches. (2)It is faster than other memory systems. What problems do they solve? Caches can improve performance where a large disparity in access time or transfer rate exists between two components

1. (a). There is one reason for a cache to exist: speed. A cache exists to speed up the time that the processor takes to obtain a bit of data. Typically, main memory is many times slower than the processor - in modern computers, it can be 1000 times slower. So, caches are made up of memory more exp

1. a. Fast and efficient b. Reduce cpu wait,because they can find instruction from caches. c. expensive d. Because caches can't always save data,so we need a device to keep our data consistent. 2. a. It reads commands from data and executes them to turn them into several system calls. b.

這一次的讀書會第一次上台報告，當初想說到時在上台看圖說故事但果然我還是沒有那個能力。我想下一次我報告之前我還是是先擬一下稿，並將需要用到的重點整理出來。 然後這次聽完別人報告後決得我的進度落後非常多，果然還是該多花些時間補回進度免得將來連累其他人。最後找到自己的目標，以便之後可以朝著自己有興趣的方向來發展。

今天的讀書會，讓我學習到要珍惜10分鐘的報告時間，只有屬於那10分鐘是屬於自己的，我也聽了很多人的報告，環型振盪器，差動放大器，我也有報告，雖然不是第一次，但還是很緊張，介紹MOS的基本結構，大致上還算可以囉~以後還要多多努力!!!
