रासायनिक अभिक्रिया किसे कहते हैं संयोजन व प्रतिस्थापन अभिक्रिया को उदाहरण सहित समझाइए​

Explanation:

Wi-Fi is the wireless technology used to connect computers, tablets, smartphones and other devices to the internet. Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use.

Explanation:

1. The word Wi-Fi was first used as a branding phrase to support and promote interoperability between various wireless LAN systems rather than as a representation of the technology itself. Wi-Fi was simply a play on the word hi-fi (high fidelity), paying respect to high-end music technology. It was never a shorter version of wireless fidelity.
2. The Wireless Ethernet Compatibility Alliance, subsequently known as the Wi-Fi Alliance, coined the term "Wi-Fi". In order to connect to other devices on the LAN, WAN, or the internet, Wi-Fi products use radio waves to send data from a client device to an access point, which also includes a router
3. Wi-Fi is used for LAN connections in places like the house or workplace, whereas 4G and 5G are utilised for connections over larger distances. Even though some of these technologies may overlap, the distance comparison is typically used as a general guideline.
4. Significance of Wi-Fi

      (a) With the aid of routers and adapters, you can carry your laptop anywhere you want and have the option of having a wireless connection. Wi-Fi is used for free at restaurants and coffee shops. It sends out data to LAN and WAN networks, which allow any connection without needing wires.

   (b) Hot spots are connected by Wi-Fi, and GSM is used by cell phone providers. This enables constant Wi-Fi connectivity, making it useful in emergency situations.

   (c) Thermostats, lightbulbs, home security, monitoring and control systems, appliances, and automobile items are all already equipped with Wi-Fi, which connects the Internet to every application that consumers demand today.

 (d) Wi-Fi is a single technology that can make all connections seamless, will be successful for applications with real-world purposes, has industry-standard security safeguards, and is trusted by consumers.

• अधिकांश तत्वों के परमाणु द्रव्यमान भिन्नात्मक होते हैं क्योंकि वे विभिन्न द्रव्यमानों के आइसोटोप के मिश्रण के रूप में मौजूद होते हैं.
• इस मिश्रण के कारण भिन्नात्मक परमाणु द्रव्यमान उत्पन्न होते हैं.
• औसत द्रव्यमान = सभी परमाणुओं का कुल द्रव्यमान / परमाणुओं की संख्या.
• कई स्वाभाविक रूप से पाए जाने वाले तत्व एक या एक से अधिक आइसोटोप के रूप में मौजूद हैं.
• आइसोटोप एक ही तत्व के परमाणु होते हैं जिनकी परमाणु संख्या समान होती है लेकिन अलग-अलग द्रव्यमान संख्याएं होती हैं.
• इस प्रकार, परमाणु द्रव्यमान इकाइयों में अधिकांश तत्वों के परमाणु द्रव्यमान में अंश शामिल होते हैं क्योंकि एक तत्व का परमाणु द्रव्यमान इसके विभिन्न आइसोटोप के सापेक्ष द्रव्यमान का औसत होता है.
• औसत लेते समय, परिणाम एक अंश के रूप में दिखाई देता है.
