Which of the following is the correct full form of ‘LAN’?
इनमें से कौन-सा ‘LAN’ का सही पूर्ण रुप है?
Detailed Solution & Logic
Local Area Network/ लोकल एरिया नेटवर्क
✅ Explanation
- Local Area Network (LAN):
- Connects devices within a small area.
- Enables sharing of resources such as files, printers, and internet connection.
- High-speed network with relatively low cost.
- Other options explained:
- Local Access Network → Incorrect, not the standard term.
- Longitudinal Area Network → Incorrect, does not exist in networking terminology.
- Link Access Node → Incorrect, this is a term used in telecom, not LAN.
Example of LAN:
- An office network where all computers are connected to the same router or switch.
- Home Wi-Fi network connecting multiple devices.
So, the correct answer is:
D) Local Area Network / लोकल एरिया नेटवर्क
✅ व्याख्या
LAN (लोकल एरिया नेटवर्क) एक नेटवर्क है जो सीमित भौगोलिक क्षेत्र में कंप्यूटर और उपकरणों को जोड़ता है।
- विशेषताएँ:
- छोटे क्षेत्र में डिवाइस कनेक्शन
- संसाधनों का साझा उपयोग (फाइलें, प्रिंटर, इंटरनेट)
- उच्च गति और कम लागत
- अन्य विकल्प:
- Local Access Network → गलत
- Longitudinal Area Network → गलत
- Link Access Node → गलत, यह टेलीकॉम में होता है
उदाहरण:
- ऑफिस का नेटवर्क, जहां सभी कंप्यूटर एक ही राउटर या स्विच से जुड़े हों।
- होम Wi-Fi नेटवर्क, जो कई डिवाइस को जोड़ता है।
इसलिए सही उत्तर है:
D) Local Area Network / लोकल एरिया नेटवर्क
