Windows 3.1 Operating Modes
Windows 3.1 has three different operating modes，called real mode, standard mode, and 386enhanced mode. When you type WIN to start Windows, the software automatically chooses the operating mode that is appropriate for your hardware．
1 ．Real Mode
Windows automatically runs in real mode on computers that use the Intel 8086 or 8088 microprocessor (or•an equivalent)and on computers with less than 1 MB of memory. When you use real mode, applications do not have access to memory beyond 640KB．
2 ．Standard Mode
Windows automatically runs in standard modern computers with at least 1 MB of memory that use the Intel 80286 microprocessor. In standard mode, your Windows applications can use memory in excess of 640 KB．You can run non-Windows application as well as Windows applications, but non-windows applications must use the full screen. In addition, non-Windows applications can run in the foreground only; that is, when you switch from a non-windows applications to another application（either a Windows application or another non-Windows application），the program you switched away from is suspended until you switch back to it.
3. 386 Enhanced Mode
(1)Windows automatically runs 386 enhanced mode on computers that use the Intel 80386，Intel80486 or Intel Pentium microprocessor and that have at least 2MB of memory. The memory must include640 KB of conventional memory plus at least 1 MB of extended memory, Windows'386 enhanced mode provides two advantages over standard mode．
(2)1n 386 enhanced mode, Windows can use free space on)our hard disk as an extension of internal(RAM) memory. When your internal memory be-comes full, Windows writes data that you're temporarily not using to the hard disk; when you need that data again，Windows retrieves it and moves other data out to disk.
(3)In 386 enhanced mode, you have more control over the way non-Windows applications run. You can display most non-Windows programs in full-screen fashion or in a Windows and you can choose to have a non-Windows application continue running even when you've switched to a different program．
4 ．WINDOWS TIP：
You can find out which operating mode Windows is using by choosing the About Command on Program Manager's Help menu. This command also tells you how much memory is currently available to Windows

Windows 3．1操作模式
Windows 3.1有三種不同的操作模式：實(shí)模式，標(biāo)準(zhǔn)模式和386增強(qiáng)模式。當(dāng)你鍵入WIN啟動(dòng)Windows時(shí)，軟件會(huì)自動(dòng)選擇合你的計(jì)算機(jī)硬件的操作模式。
1.實(shí)模式
當(dāng)你計(jì)算機(jī)使用Inte18086/8088微處理器（或同檔次的）且內(nèi)存少于1MB時(shí)Windows自動(dòng)運(yùn)行于實(shí)模式下，在使用實(shí)模式時(shí)，應(yīng)用程序不能訪問(wèn)超過(guò)640KB的內(nèi)存。
2.標(biāo)準(zhǔn)模式
當(dāng)計(jì)算機(jī)有至少1MB內(nèi)存使用Inte180286微處理器時(shí)，Windows自 動(dòng)運(yùn)行于標(biāo)準(zhǔn)模式下。在標(biāo)準(zhǔn)模式下，Windows應(yīng)用程序可以使用超過(guò)640KB的內(nèi)存。你可以同時(shí)運(yùn)行Windows應(yīng)用程序一樣運(yùn)行非Windows應(yīng)用程序，但非Windows應(yīng)用程序必須使用全屏幕。還有一點(diǎn)，非Windows應(yīng)用程序只能在前臺(tái)運(yùn)行，也就是說(shuō)，當(dāng)你從一個(gè)非Windows應(yīng)用程序切換到別的應(yīng)用 程序（可以是Windows應(yīng)用程序，也可以是非Windows應(yīng)用程序）時(shí)，被切換掉的程序?qū)⒈粧炱鹬钡侥阒匦虑袚Q回去為止。
3．386增強(qiáng)模式
(I)計(jì)算機(jī)使用1NTEL80386, 80486或Intel奔騰微處理器，且有至少2MB內(nèi)存時(shí)，Windows自動(dòng)運(yùn)行386增強(qiáng)模式下。內(nèi)存必須包括640KB的常規(guī)內(nèi)存，加上至少1MB的擴(kuò)展內(nèi)存Windows386增強(qiáng)模式有兩項(xiàng)超過(guò)標(biāo)準(zhǔn)模式的優(yōu)點(diǎn)。
(2)在386增強(qiáng)模式中，Windows能使用硬盤上的剩余空間作為內(nèi)存的擴(kuò)充。當(dāng)內(nèi)存被占時(shí)Windows把暫時(shí)不用的數(shù)據(jù)寫到硬盤上，當(dāng)你需要使用它們時(shí)，Windows把它們調(diào)入內(nèi)存而把另一些數(shù)據(jù)放到硬盤上。
(3)在386增強(qiáng)模式廠，你能夠 有更多控制非Windows應(yīng)用程序運(yùn)行的方式你可以讓多個(gè)Windows程序顯示在整個(gè)屏幕或一個(gè)窗口中，甚至在你已切換到了另一個(gè)不同的應(yīng)用程序情形下，你還可以選擇一個(gè)非Windows應(yīng)用程序繼續(xù)執(zhí)行。
4 ．Windows提示
你可以通過(guò)選擇Program Manger（程序管理器）中的Help（幫 助）菜單中的About Command（關(guān) 于命令）選擇項(xiàng)來(lái)查看Windows在 使用何種操作模式。這條命令還會(huì) 告訴你當(dāng)前的Windows可用的內(nèi)存 有多少。
