Which network technology is predominantly used for mobile communication?

• A. GSM
• B. Ethernet
• C. Wi-Fi
• D. Bluetooth

Answer: (A)

GSM, or Global System for Mobile Communications, is the predominant network technology used for mobile communication. It is widely recognized for its role in mobile phone networks and supports various services, including voice calls and data transmission. GSM technology allows mobile devices to connect to cellular networks, facilitating reliable communication over large distances. In contrast, the other technologies listed serve different purposes. Ethernet is primarily used for wired local area networks (LANs), making it suitable for connecting devices within a local setting but not for mobile communications. Wi-Fi is designed for wireless local area networks, providing internet access over short distances, but it does not support the broader mobile communication that GSM does. Bluetooth is intended for short-range communication between devices, typically for data transfer or connecting peripherals, rather than for extensive mobile communication networks. Thus, while these technologies have their applications, GSM remains the standard for mobile communication on a global scale.
