​Jatin's smartphone has a SIM card installed but Amit's Tablet is without a SIM card. Amit would like to access the internet using Jatin's smartphone network connection. Which of the following could be used to connect the tablet device to the internet?​​​

Correct option is C

Tethering is the process that allows a smartphone with an active mobile data connection to share its internet access with other devices like tablets, laptops, etc., using Wi-Fi, Bluetooth, or USB. Since Amit's tablet has no SIM card, it can’t directly access mobile data. However, by connecting to Jatin’s phone via tethering, Amit can use the phone's internet.
Information Booster:
1. Tethering Defined: It is a network sharing technique that allows mobile phones to function as modem/hotspots for other devices.
2. Types of Tethering:
o Wi-Fi Tethering: Turns phone into a wireless hotspot.
o USB Tethering: Shares internet via cable connection.
o Bluetooth Tethering: Uses Bluetooth PAN profile for sharing data.
3. Use Case in Question: Amit's tablet, though without a SIM, can connect to the internet if Jatin enables mobile hotspot or tethering on his smartphone.
4. Devices Involved:
o Jatin’s phone: With SIM and internet.
o Amit’s tablet: No SIM, but Wi-Fi enabled.
o Tethering bridges the gap.
Additional Knowledge:
• GPS is for location tracking, not internet access.
• Notifications are alert systems that depend on internet, not a method to access it.
• Messaging (like SMS) requires a SIM card and is unrelated to data sharing or tethering.
