STD Full Form In English
STD stands for Subscriber Trunk Dialing. It is a telephone system that allows subscribers to make long-distance calls without the help of an operator. Before the introduction of STD, people had to request operators to connect their calls, especially for intercity or long-distance communication. With the development of this system, calling became faster, easier, and more private, as users could directly dial the code of the city followed by the desired number. STD codes are assigned to different cities and regions, making it simple to identify the geographical location of the call.
This technology played a significant role in revolutionizing the communication system by saving time and reducing dependency on manual connections. Even today, STD codes remain an important part of telecommunication, particularly in landline networks, although mobile phones and internet-based calling have largely replaced traditional STD dialing.
STD Full Form In Hindi
एसटीडी (STD) का अर्थ है Subscriber Trunk Dialing। यह एक ऐसी दूरसंचार प्रणाली है जिसके माध्यम से ग्राहक बिना ऑपरेटर की मदद के सीधे लंबी दूरी या अंतर-शहरी कॉल कर सकते हैं। पहले के समय में लंबी दूरी पर बात करने के लिए टेलीफोन ऑपरेटर की सहायता लेनी पड़ती थी, जिससे समय अधिक लगता था। लेकिन एसटीडी की सुविधा आने के बाद उपयोगकर्ता केवल संबंधित शहर का एसटीडी कोड और फ़ोन नंबर मिलाकर आसानी से कॉल कर सकते हैं। प्रत्येक शहर और क्षेत्र के लिए अलग-अलग एसटीडी कोड निर्धारित होते हैं, जिससे कॉल करना सरल और तेज़ हो जाता है। इस प्रणाली ने संचार जगत में बड़ा परिवर्तन किया और लोगों का समय बचाया। आज भले ही मोबाइल फोन और इंटरनेट कॉलिंग ने इसका स्थान ले लिया हो, फिर भी एसटीडी कोड लैंडलाइन नेटवर्क का एक महत्वपूर्ण हिस्सा बने हुए हैं।
