1.Reason 1: caches are useful when two or more components need toexchange data, and the components perform transfers at different speeds. E.g., the CU registers and the disk are wo such components. Caches solve this problem byproviding a buffer of intermediate speed to store part of the data

應用「雲端虛擬實驗室(CVLab)」中的槓桿轉動實驗,配合引導式探究策略所發展的實驗活動,以學習者爲中心,採用分組合作學習的方式,讓學生經由探索、操作的活動、熟悉探討的方法、經由實作過程,將實驗內容與結果,做有條理性和科學性的陳述,以期獲得科學知識和技能。 研究對象為19位八年級學生,經由「雲端虛擬實驗室(CVLab)」的實驗活動,學習者透過實驗觀察、動手操作、與組員討論,結果顯示學生比較不害怕實驗課程,「雲端虛擬實驗室(CVLab)」模擬程式的介面操作並不因難,學生充份了解儀器的組合及實驗步驟,不但提高了學習者的學習興趣,同時透過實驗,學生理解了槓桿原理並能運用所學於日常生活中。

1. Message passing models (Erlang, for example) do not have any shared state; all synchronization and communication is done by exchanging messages. Shared memory models communicate by reading/writing to shared memory blocks, which are protected by semaphores or similar. Message passing's pro

在我尚未入學前就知道我所讀的這個系必須在大三的時候出國進修,這成了我最大的動機進入就讀,不為其它的,就為了出國看看世界,把學習當作旅遊 。一直到了大一下, 我漸漸覺得...在我大學四年裡,有需要出國進修嗎? 為什麼我這麼想? 首先,我覺得最大的關鍵點在---花費,出國不外乎要準備一大筆資金,尤其在國外待一年,龐大的花費是可想而知的,歐洲各國及美國的物價又是數一數二的高!!! 想當然,家庭的負擔一定不會小。再者,好吧! 花費大,那我拚拚看交換生,可惜小子我少小不讀書,英文基礎沒打好,長大了上學又白混只想著玩,所以學期平均成績下來還挺難看的。再不然,把托福考好點? 好...我考了兩次,成績還是不慎
