A wireless technology built in electronic gadgets used for exchanging data over short distances is:
कम दूरी पर डेटा के आदान-प्रदान के लिए इलेक्ट्रॉनिक उपकरणों में अंतर्निहित एक वायरलेस तकनीक कौन-सी है?
EXPLANATION Introduction to Bioinformatics: Scope, Biological Databases (NCBI, GenBank, EMBL, UniProt, PDB) and Data Retrieval

Short-range wireless communication standards:

  • Wi-Fi (IEEE 802.11) is designed for local area wireless networking (WLAN) over medium ranges (up to $100\text{ meters}$).
  • Bluetooth (IEEE 802.15.1) is specifically engineered as a short-range wireless personal area network (WPAN) protocol operating in the $2.4\text{ GHz}$ ISM band over distances typically up to $10\text{ meters}$.
  • modem is a hardware device for modulating/demodulating signals over telecommunication lines.
  • USB is a wired communication bus protocol.

वायरलेस संचार तकनीकें:

  • वाई-फाई मध्यम दूरी के स्थानीय नेटवर्क (WLAN) के लिए प्रयुक्त होता है।
  • ब्लूटूथ व्यक्तिगत इलेक्ट्रॉनिक उपकरणों के मध्य लगभग $10\text{ मीटर}$ की सीमित दूरी पर वायरलेस डेटा आदान-प्रदान हेतु विशेष रूप से डिजाइन की गई तकनीक है।
  • मॉडेम सिग्नलों के मॉड्यूलेशन/डिमोड्यूलेशन का उपकरण है।
  • यूएसबी एक वायर्ड केबल मानक है।
