Which of the following is a common technique for accessing the internet?
निम्नलिखित में से कौन-सा तरीका, PC को सुरक्षित करने के लिए उपयोगी नहीं हैं?
Detailed Solution & Logic
Dial-up/ डायल-उप
Explanation / व्याख्या:
Accessing the Internet / इंटरनेट तक पहुँच:
- Dial-up is a method of connecting a computer to the internet using a telephone line.
डायल-अप एक तरीका है जिसमें कंप्यूटर को इंटरनेट से जोड़ने के लिए टेलीफोन लाइन का उपयोग किया जाता है। - It was popular in the 1990s before broadband became widely available.
यह 1990 के दशक में ब्रॉडबैंड के आने से पहले लोकप्रिय था। - Requires a modem to convert digital signals into analog signals and vice versa.
इसके लिए एक मो्डेम की आवश्यकता होती है जो डिजिटल सिग्नल को एनालॉग में और एनालॉग को डिजिटल में बदल सके।
❌ Why other options are incorrect / अन्य विकल्प क्यों गलत हैं:
- Bluetooth / ब्लूटूथ → Incorrect
- Bluetooth is used for short-range device communication, not for internet access.
ब्लूटूथ का उपयोग छोटे रेंज के डिवाइस कम्युनिकेशन के लिए किया जाता है, इंटरनेट एक्सेस के लिए नहीं।
- Bluetooth is used for short-range device communication, not for internet access.
- USB → Incorrect
- USB is a hardware interface for connecting devices; it does not provide internet connectivity on its own.
USB एक हार्डवेयर इंटरफेस है जो डिवाइस को जोड़ने के लिए उपयोग होता है; यह स्वयं इंटरनेट कनेक्टिविटी नहीं देता।
- USB is a hardware interface for connecting devices; it does not provide internet connectivity on its own.
- NFC (Near Field Communication) / एनएफसी → Incorrect
- NFC is used for contactless communication over very short distances (e.g., payments) and not for general internet access.
NFC का उपयोग बहुत कम दूरी पर कॉन्टैक्टलेस कम्युनिकेशन (जैसे पेमेंट) के लिए किया जाता है, सामान्य इंटरनेट एक्सेस के लिए नहीं।
- NFC is used for contactless communication over very short distances (e.g., payments) and not for general internet access.
Extra Facts / अतिरिक्त तथ्य :
- Speed / गति:
- Dial-up is very slow compared to modern broadband or fiber-optic connections (typically 56 Kbps).
डायल-अप आधुनिक ब्रॉडबैंड या फाइबर-ऑप्टिक कनेक्शन की तुलना में बहुत धीमा है (आमतौर पर 56 Kbps)।
- Dial-up is very slow compared to modern broadband or fiber-optic connections (typically 56 Kbps).
- Security / सुरक्षा:
- Dial-up connections are relatively secure because they are temporary and direct, but very slow.
डायल-अप कनेक्शन अपेक्षाकृत सुरक्षित होते हैं क्योंकि वे अस्थायी और सीधे होते हैं, लेकिन बहुत धीमे हैं।
- Dial-up connections are relatively secure because they are temporary and direct, but very slow.
- Fun Fact / मजेदार तथ्य:
- Many people remember the “screeching modem sound” when connecting to the internet via dial-up.
कई लोग डायल-अप के दौरान मोडेम की चरमराहट वाली आवाज़ को याद करते हैं
- Many people remember the “screeching modem sound” when connecting to the internet via dial-up.
