計算機與因特網上外掛指導

General 更新 2024年12月24日

  外掛是一種遵循一定規範的應用程式介面編寫出來的程式。很多軟體都有外掛,外掛有無數種。接下來小編為大家整理,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.

  當你不再僅僅限於文字和靜止圖片時,網上生活會豐富多彩得多。即使是個因特網新手,你也許聽說過線上式多媒體——聽音樂、看動畫和錄影,甚至玩三維遊戲。聲音和活動畫面使資訊變得活靈活現。

  要體驗這些,你需要叫作“外掛”的特殊軟體。術語“外掛”指的是一個附加的小軟體,他能夠擴充套件你的網路瀏覽器比如網景的導航者或微軟的探索者的功能——把你的計算機變成一臺收音機或電視機。

  當你進入的網頁含有需要使用外掛程式的檔案,而你卻又沒有這個程式時,通常你會收到一個資訊,詢問你是否需要下載該程式並安裝到你的電腦裡。多數情況下安裝是自動執行的。

  有時候,你會碰到一個需要在安裝前先進行解壓縮的下載檔案。一旦安裝完畢,外掛就會自動執行,無需你做任何事。

  許多多媒體的控制程式仍需從開發商處索取,不過都是自動安裝的。

  Shockwave 就是這方面一個很好的例子。你所需要做的就是到Macromedia網站上點選連結來安裝ActiveX控制程式,剩下的事自動就會完成。下次再到一個需要使Shockwave 的網站時,Shockwave控制程式就會自動裝載並播放電影。

  大多數外掛和控制程式可以從因特網上免費下載,儘管並非所有這些程式都會在每一個系統上正常執行。例如有些就只適用於視窗95.
