Source code is written by programmers and is essentially a list of instructions to a computer which humans are able to read and write. 源代碼是由程序員編寫(xiě)的，本質(zhì)上是一連串的人們能夠閱讀和編寫(xiě)的計算機指令。
An assembler language programmer writes one mnemonic instruction for each machine-level instruction. 匯編語(yǔ)言程序設計員為每條機器指令寫(xiě)一條助記符指令。
Because of the one-to-one relationship between the language and the machine, assemblers are machine dependent, and a program written for one type of computer won't run on another. 因為匯編指令和機器指令之間存在一一對應的關(guān)系，匯編語(yǔ)言和機器語(yǔ)言都是依賴(lài)于機器的，所以為一種型號計算機編寫(xiě)的程序不能在另一種型號的機器上執行。
