插件是一種遵循一定規(guī)范的應(yīng)用程序接口編寫出來的程序。很多軟件都有插件，插件有無數(shù)種。接下來小編為大家整理計(jì)算機(jī)與因特網(wǎng)上插件指導(dǎo)，希望對你有幫助哦!

　　Life on-line can be a much richer experience when you aren't restricted to just written words and still pictures. Even if you're new to the Net， you've probably heard aobut multimedia on-line——listening to audio， watching animations and videos， even playing in three-dimensional space. Sound and movement make information come alive. To experience it， you'll need special pieces of software called plug-ins. The term "plug-in" refers to a small， add-on piece of software which extends the capabilities of your web browser， like Netscape Navigator or Microsoft Explorer， turning your computer into a radio or TV.

　　When you arrive at a web page which contains a file requiring a plug-in which you don't have， you will usually receive a message asking if you want to get it by downloading it and installing it into your computer. Most of the time， the installation will be automatic.

　　Occasionally， you'll run into a downloaded file which needs to be decompressed or un-zipped before installation. Once installed， plug-ins run automatically， without you having to do anything.

　　Many multimedia controls still need to be obtained from the developer but are installed automatically.

　　Shockwave is a good example of this. All you need to do is go to the Macromedia site and click on the link to install the ActiveX control. The rest happens automatically. The next time you go to a "Shocked" website， the Shockwave control loads and plays the movie.

　　Most plug-ins and controls can be downloaded for free on the Internet， although not all will work with every system. Some of them， for instance， only work with windows95.

　　當(dāng)你不再僅僅限于文字和靜止圖片時(shí)，網(wǎng)上生活會(huì)豐富多彩得多。即使是個(gè)因特網(wǎng)新手，你也許聽說過在線式多媒體——聽音樂、看動(dòng)畫和錄像，甚至玩三維游戲。聲音和活動(dòng)畫面使信息變得活靈活現(xiàn)。

　　要體驗(yàn)這些，你需要叫作“插件”的特殊軟件。術(shù)語“插件”指的是一個(gè)附加的小軟件，他能夠擴(kuò)展你的網(wǎng)絡(luò)瀏覽器(比如網(wǎng)景的導(dǎo)航者或微軟的探索者)的功能——把你的計(jì)算機(jī)變成一臺(tái)收音機(jī)或電視機(jī)。

　　當(dāng)你進(jìn)入的網(wǎng)頁含有需要使用插件程序的文件，而你卻又沒有這個(gè)程序時(shí)，通常你會(huì)收到一個(gè)信息，詢問你是否需要下載該程序并安裝到你的電腦里。多數(shù)情況下安裝是自動(dòng)運(yùn)行的。

　　有時(shí)候，你會(huì)碰到一個(gè)需要在安裝前先進(jìn)行解壓縮的下載文件。一旦安裝完畢，插件就會(huì)自動(dòng)運(yùn)行，無需你做任何事。

　　許多多媒體的控制程序仍需從開發(fā)商處索取，不過都是自動(dòng)安裝的。

　　Shockwave 就是這方面一個(gè)很好的例子。你所需要做的就是到Macromedia網(wǎng)站上點(diǎn)擊鏈接來安裝ActiveX控制程序，剩下的事自動(dòng)就會(huì)完成。下次再到一個(gè)需要使Shockwave 的網(wǎng)站時(shí)，Shockwave控制程序就會(huì)自動(dòng)裝載并播放電影。

　　大多數(shù)插件和控制程序可以從因特網(wǎng)上免費(fèi)下載，盡管并非所有這些程序都會(huì)在每一個(gè)系統(tǒng)上正常運(yùn)行。例如有些就只適用于視窗95.
