當(dāng)你想將信息輸入電腦，只需要在鍵盤上敲打字母和數(shù)字。在所有輸入設(shè)備中，鍵盤是最常使用的。沒有鼠標(biāo)我們?nèi)阅苡面I盤工作，因?yàn)樗惺髽?biāo)的工作都可以用鍵盤來完成。然而沒有鍵盤就不可能完成任務(wù)。因此作為電腦初學(xué)者，第一步就是學(xué)會(huì)使用鍵盤。

通常來說，鍵盤分為六大區(qū)和四個(gè)附加鍵。字母與數(shù)字鍵區(qū)占據(jù)了鍵盤的絕大部分，位于鍵盤的左部。一共是26個(gè)字母和10個(gè)數(shù)字。剩余的絕大部分是控制鍵。在上方我們可以看到功能鍵，它們分別執(zhí)行不同的任務(wù)。數(shù)字鍵區(qū)在鍵盤右部。在字母和數(shù)字鍵之間是特殊功能鍵和方向鍵。

如果你想打字很快僅僅對(duì)鍵盤有個(gè)大概了解還不夠。有些人電腦很在行因?yàn)樗麄儠?huì)盲打，就是說他們打字很快。盲打也叫按指法打，指的是不看鍵盤用手指輸入文本。聽起來很有趣，事實(shí)上，學(xué)會(huì)盲打需要時(shí)間，你需要不斷地學(xué)習(xí)與練習(xí)。

另一種經(jīng)常用到的硬件是軟盤。它可移動(dòng)，可以方便隨身攜帶。你可以用軟盤從電腦上拷貝文件，然后隨身攜帶。然而它的容量相對(duì)很小，今天已逐漸被U盤——一種更小但是容量很大的移動(dòng)硬盤——所代替。譯文Windows
