2012 dse lq 1d(v) 點解係smtp?
明明佢係send去個mail server到 應該係用imap架喎

:^(

SMTP and IMTP 個用途唔同架

簡單記
SMTP is user send out 去 email server 用
IMAP 或者 POP 係由 email server 收 email時侯用

正解
最好記埋pop imap 既優點缺點

streaming唔係指邊down邊播咩？點可以view smoothly？佢既好處唔係唔使等咩？

佢increase bandwidth即係點

2012 DSE 3d (2)(3) 點做?

:^(

:^(

a) a<- a+b

（1）所以memory addreaa 10000000 咪係佢地加埋
（2）MAR係store data要transfer去既address 咁佢要去A咁咪係A既addresa
（3）MDR係store 要transfer既data
咁就係A+B既value

:^(

好似係咁

本書寫mar係保留將送出/接收數據個address
佢唔係將10000001加去10000000度咩? 唔係應該要保留10000000咩

啱呀，A嘅address係1000 0000, 所以（2）嘅答案咪就係1000 0000囉

唔用串流 -> 要down成條片先有得睇 ,因為條片好大 所以有機會因為硬件問題lag
用串流 -> 逐小逐小down + 睇 , 相對黎講唔會lag

identity code 有10bit即係可以有2^10次唔同既code 所以係1024

3我理解係頭個位係sign bit 咁A係正 加左之後就變負數 但唔係負嫁嘛
所以有overflow
