2-1.Microprocessors
In a microcomputer system,the central processing unit(CPU) or processor is contained on a single chip called the microprocessor.The microprocessor is either mounted onto a carrier package that plugs into the system board or contained within a cartridge that plugs into a special slot on the system board (See Figure1-6).The microprocessor is the "brains" of the computer system. It has two basic components:the control unit and the arithmetic-logic unit. Functions of these two units have be mentioned in section 1.1 of this textbook.

在微機系統中，中央處理單元(CPU)或處理器包含在稱爲微處理器的單片機上。
The microprocessor is either mounted onto a carrier package that plugs into the system board or contained within a cartridge that plugs into a special slot on the system board (See Figure1-6).
微處理器要麼安裝在插入系統板的載體包上，要麼包含在插入系統板上特殊插槽的墨盒中（見圖1-6）。
The microprocessor is the "brains" of the computer system.
微處理器是計算機系統的「大腦。
It has two basic components:the control unit and the arithmetic-logic unit.
它有兩個基本組成部分：控制單元和算術邏輯單元。
Functions of these two units have be mentioned in section 1.
第1節提到了這兩個單位的職能。

在微型計算機系統中，中央處理器（CPU）或稱處理器，包含在一個芯片上，又稱爲微處理器。微處理器便可以安裝在插入到主板上的承載插件上，也能夠安裝在插入到主板專用插槽的盒上，如圖1-6所示。微處理器是計算系統的「大腦」。它有兩個基本部件：控制器和算術-邏輯部件。這兩個部件的功能已在本書的1.1節中介紹過。
