翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Postal, telegraph and telephone service ： ウィキペディア英語版 Postal, telegraph and telephone service A postal, telegraph, and telephone service (or PTT) is a government agency responsible for postal mail, telegraph, and telephone services. Such monopolies existed in many countries, though not in North America or Japan. Many PTTs have been partially or completely privatized in recent years. In some of those privatizations, the PTT was renamed completely, whereas in others, the name of the privatized corporation has been only slightly modified, such as PT Telkom in Indonesia. ==Monopoly service== In countries that had a PTT unit of government, typically the vast majority of forms of distribution of information fell under the auspices of the PTT, whether that be the delivery of printed publications and individual letters in the postal mail, the transmission of telephonic audio, or the transmission of telegraphic on-off signals, and in some countries, the broadcast of one-way (audio) radio and (audio-video) television signals. In many countries with a current or former PTT, the PTT also was responsible for the manufacture and standardization of telephone equipment. Often the presence of a single PTT in a country implied a single monolithic approach to the distribution of information in that country, which as an advantage permitted efficient deployment of a single national standard for each topic instead of ongoing debate about competing ideas, but which as a disadvantage typically stifled alternative ideas from emerging once a legacy implementation had been widely deployed. 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「Postal, telegraph and telephone service」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.
