電腦科學(又叫做計算機科學,英文:Computer science)係研究資訊計算基礎,同埋點樣砌電腦系統嘅專業學問[1][2][3]。電算入面分好多門,有啲專門諗電算出來嘅結果,好似電腦圖象(Computer graphics),有啲就諗計算問題(Computational problem),好似計算複雜度理論(Computational complexity theory),有啲就諗點去用出來,好似編程語言理論(Programming language theory)會諗點表示電算,而電腦編程(Computer programming)就係用一隻編程語言去搞掂一啲電算難題。重有一啲會諗人同電腦互動,即係諗下點樣整電腦,編電算,先至係有用,用得到,重要個個都用得到。

研究同做呢門嘅人就叫電算師(Computer scientist)。

歷史[編輯]

電算呢門可以追返上去未有摩登電腦嘅遠古時代。人諗咗好多架生來計數,好似算盤咁。威廉嶭卡(Wilhelm Schickard)1623年起咗第一部可以機械計數機[4] 去到維多利亞時代,Charles Babbage 設計咗部差分機(Difference engine)[5], and around 1900 the IBM corporation sold punch-card machines[6]。不過呢啲咸不爛都係做一樣,至叻都係可以做多幾樣,同電腦差得遠。
