翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Communications blackout ： ウィキペディア英語版 Communications blackout In telecommunications, communications blackouts are * a cessation of communications or communications capability, caused by a lack of power to a communications facility or to communications equipment. * a total lack of radio communications capability, caused by ionospheric anomalies, e.g., during strong auroral activity or during re-entry of a spacecraft into the Earth's atmosphere. ==Technical failures== Uptime being a key goal of most communications networks, uninterruptible power supplies and backup generators are typically used to ensure high-reliability power. Wireless networks may be subject to radio jamming; wired networks can be physically severed. Network design can also play a role in maintaining communications reliability; depending on the constraints in building a fiber-optic network, a self-healing ring topology may be used. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Communications blackout」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
