# 資訊科學

## 基礎概念

• 喺做通訊嗰陣，傳訊嘅人會以某啲方法（好似係文字訊號或者摩斯碼呀噉）向收訊嘅人傳達訊號（將資訊用訊號表達），收訊嘅人收到訊號之後要按照佢對嗰種訊號嘅認識解讀傳訊嘅人想講嘅嘢（重新建構），並且知道對方想表達啲乜（不確定性減少）[4]
• 又或者用神經科學嚟做例子，對視網膜上面每一粒感光細胞喺受到外界嘅刺激嗰陣，會向個腦嘅視覺區域射神經訊號，而個訊號嘅物理性質（例如係頻率）會按照佢感覺到嘅光嘅屬性而有所不同－例如係光嘅強度同射訊號嘅頻率成簡單正比${\displaystyle f=\beta I}$ ，當中 ${\displaystyle f}$  係訊號嘅頻率，${\displaystyle \beta }$  係一個固定嘅常數，而 ${\displaystyle I}$  係光嘅強度（將資訊用訊號表達），呢啲訊號跟住會上腦，話俾個腦知佢睇到啲乜（可能有雜音嘅管道），而個腦本來唔知眼前有啲乜嘅（不確定性），但佢由感光細胞嗰度收到神經訊號，知道 ${\displaystyle f}$ ，再解讀個訊號得知 ${\displaystyle I}$ （重新建構），就知眼前有啲乜嘢（不確定性減少）[5]
