A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.

A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques.

In signal processing, a signal is a function that conveys information about a phenomenon. In electronics and telecommunications, it refers to any time varying voltage, current or electromagnetic wave that carries information. A signal may also be defined as an observable change in a quantity.

時間管理是非常重要。在通街大學生的時代，學生要盡可能的增值自己。這本書教你如何在學習與社交之間取得平衡。當時我沒把書中的內容放在心上，只是很快的讀了一次。現在過了兩年，我重新看一下這本書，原來當年書中的指示已經不知不覺在我心裏埋下種子。

廢文慎入。 簡單說一下，自從開了這個blog之後，我的學習動力是提高了的。上一個學期的成績也考的不錯。我覺得原因有一半是出於我把所有的pastpaper都刷了一次，另一半是就我在博文弄的筆記。我盡量花時間把上堂學的東西簡化然後寫在筆記，再以例子加以說明。

最近幾日都係到狂玩呢隻game...玩到飯唔食書唔讀...童年玩洛克人嘅回憶都番哂黎了！
