GSM and CDMA are two types of what?

GSM and CDMA are two types of cellular networks. Both are communication technologies used for mobile phone systems to enable voice calls and data transfer. GSM, which stands for Global System for Mobile Communications, is widely used around the world and is known for its SIM card use and ability to provide services like SMS and mobile internet. CDMA, or Code Division Multiple Access, is another mobile technology that utilizes a different method of encoding multiple conversations on the same channel, allowing for more efficient use of bandwidth.

Understanding that GSM and CDMA are specifically tied to cellular communications helps distinguish them from other options. Internet networks refer to systems that connect computers globally, broadband technologies relate to high-speed internet access, and satellite systems are used for communication via satellite rather than traditional ground infrastructure. Recognizing the specific context of GSM and CDMA within the realm of cellular networks clarifies why the correct choice is the designation as types of cellular networks.
