A LAN is a Local Area Network: a way of linking computers that sit near each other — in one home, one office, one school building — so people can share files, a printer, or the same internet connection. “Local” here means “in this place,” not “across the country.” A WAN (wide area network) is the bigger cousin, reaching much farther.

A LAN is a Local Area Network一個LAN就是Local Area Network（區域網路）： a way of linking computers that sit near each other把彼此靠得很近的電腦連接起來的一種方式—— in one home, one office, one school building像是同一個家、同一個辦公室、同一棟學校建築裡—— so people can share files, a printer, or the same internet connection這樣大家就可以共用檔案、印表機，或是同一個網路連線。"Local" here means "in this place,"這裡的「local」指的是「在這個地方」， not "across the country."不是「橫跨整個國家」。A WAN (wide area network)WAN（wide area network廣域網路） is the bigger cousin是它比較大的表親， reaching much farther可以連到更遠的地方。

In IT, people say LAN all the time and write it in capital letters because it is a short form. In ordinary talk, many people just say “the wifi” or “the network,” even when they mean a LAN.

In IT在IT（資訊科技）領域， people say LAN all the time人們常常直接說LAN， and write it in capital letters而且會全部大寫， because it is a short form因為那是縮寫。In ordinary talk在日常對話裡， many people just say很多人就直接說 "the wifi" or "the network,"「wifi」或「network（網路）」， even when they mean a LAN就算他們其實指的是LAN。

Though actually, wifi is only the wireless kind; a LAN can also be made with cables. A “LAN party” is when friends bring computers to one room and play on the same local network.

Though actually不過話說回來， wifi is only the wireless kindwifi只是無線的那一種； a LAN can also be made with cablesLAN也可以用線材來架設。A "LAN party"「LAN party」 is when friends bring computers to one room是指朋友們把電腦帶到同一個房間， and play on the same local network在同一個區域網路上一起玩遊戲。
