汇编

彙編語言(Assembly language),又叫組合語言,是一種與硬體緊密相關的程式設計語言,是一種低階語言。組合語言是機器語言的便於記憶和理解的符號化形式。 組合語言的語句與機器語言操作碼存在一一對應的關係,但這並不意味著組合語言語句與機器操作一一對應。在CISC(複雜指令集)結構的CPU上,組合語言(或一個機器語言操作碼)可能被組譯器翻譯成多個「微指令」給CPU執行。

機器語言

机器语言是用二进制代码表示的计算机能直接识别和执行的一种机器指令的集合。它是计算机的设计者通过计算机的硬件结构赋予计算机的操作功能。机器语言具有灵活、直接执行和速度快等特点。不同型号的计算机其机器语言是不相通的,按着一种计算机的机器指令编制的程序,不能在另一种计算机上执行。 用机器语言编写程序,编程人员要首先熟记所用计算机的全部指令代码和代码的涵义。手编程序时,程序员得自己处理每条指令和每一数据的存储分配和输入输出,还得记住编程过程中每步所使用的工作单元处在何种状态。这是一件十分繁琐的工作,编写程序花费的时间往往是实际运行时间的几十倍或几百倍。而且,编出的程序全是些0和1的指令代码,直观性差,还容易出错。现在,除了计算机生产厂家的专业人员外,绝大多数程序员已经不再去学习机器语言了。
- 机器语言是微处理器理解和使用的,用于控制它的操作二进制代码。
- 8086PENTIUM的机器语言指令长度可以从1字节到13字节。
- 尽管机器语言好像复杂的,然而它是有规律的。
- 存在着多至100000种机器语言的指令。这意味着不能把这些种类全部列出来。 以下是一些範例 :
- 指令部份的範例
- #0000 代表 載入(LOAD)
- #0001 代表 儲存(SET) ...
- 暫存器部份的範例
- #0000 代表暫存器 A
- #0001 代表暫存器 B ...
- 記憶體部份的範例
- #000000000000 代表位址為 0 的記憶體
- #000000000001 代表位址為 1 的記憶體
- #000000001000 代表位址為 16 的記憶體
- #100000000000 代表位址為 2^11 的記憶體
- 整合範例
- #0000,0000,000000001000 代表 LOAD A, 16
- #0000,0000,000000000001 代表 LOAD B, 1
- #0000,0001,000000001000 代表 STORE B, 16
- #0000,0001,000000000001 代表 STORE B, 1 Category:计算机语言 ja:機械語 ko:기계어 simple:Machine code

CPU

]] 中央處理器,英文縮寫為CPU,即Central Processing Unit,是電子計算機的主要設備之一。它的結構如下:
- 運算器:算數、邏輯(部件:算數邏輯單元累加器暫存器組、路徑轉換器、數據匯流排)
- 控制器:復位、使能(部件:計數器指令暫存器指令解碼器狀態暫存器時序產生器、微操作信號發生器)

Shikumen
Shikumen (Simplified Chinese: 石库门), or literally "stone gate" is a style of housing in Shanghai, China, which blended features of east and west. In the past up to 80% of the city's population lived in these types of houses, but today the proportion is much lower. Each residence is connected and arranged in straight alleys, with the entrance to each alley, the gate, wrapped by a stylistic stone arc. The Shikumen is a cultural blend of
Chinese names
Chinese personal names follow a number of conventions different from those of Western personal names. Most noticeably, a Chinese name is written with the surname first and the given name second. For instance, the basketball player Yao Ming is Mr. Yao, not Mr. Ming. Note however, some Chinese people who emigrate to or do business with Western countries sometimes adopt a Westernized name, usually with a Western first name together with their surname, which is then written in the usual Western order with the surname last. Other Chinese people someti
Wikipedia:Series
Article series are useful for tying together information on very broad subjects. For example, the article Israeli-Palestinian conflict could contain a table that provides links to all the major issues surrounding that subject. Note that an alternative to an article series (for instance, where only one title is appropriate for the entire exposition) is a single, long, tightly written article. Wikipedia:Long article layout provides guidelines for such articles.
Diplomonad
The diplomonads are a group of flagellates, most of which are parasitic. They include most notably Giardia lamblia, which causes giardiasis in humans. They are placed among the metamonads, and appear particularly close relatives of the retortamonads. Most diplomonads are double cells: they have two
