LTE (Long-Term Evolution) is a cellular network technology that provides high-speed data connectivity. It is an evolution of the GSM and CDMA standards and offers significantly faster data rates and lower latency.

Wi-Fi networks primarily operate in the 2.4 GHz and 5 GHz frequency ranges. The 2.4 GHz band is commonly used for home and office networks, while the 5 GHz band is often used for high-speed applications and to reduce interference.

Bluetooth is a short-range wireless technology that allows devices to communicate over short distances. It is commonly used for connecting devices such as smartphones, laptops, and headphones.

The TCP (Transmission Control Protocol) protocol is responsible for ensuring reliable data transmission between two devices. It establishes a connection between the devices and manages the flow of data, ensuring that data is delivered in the correct order and without errors.

NFC (Near Field Communication) is a mobile device connectivity standard that allows devices to communicate with each other by touching or bringing them close together. It is commonly used for contactless payments, data exchange, and device pairing.

The maximum theoretical speed of a Wi-Fi network operating in the 802.11ac standard is 3 Gbps. This speed is significantly faster than previous Wi-Fi standards and allows for high-speed data transfers and streaming.

GSM (Global System for Mobile Communications) is a cellular network technology that provides voice and data connectivity. It is widely used around the world and is known for its reliability and coverage.

The DNS (Domain Name System) protocol is responsible for translating domain names into IP addresses. This allows users to access websites and online services by using easy-to-remember domain names instead of complex IP addresses.

LTE (Long-Term Evolution) is a mobile device connectivity standard that allows devices to communicate over long distances using cellular networks. It is an evolution of the GSM and CDMA standards and offers significantly faster data rates and lower latency.

The DHCP (Dynamic Host Configuration Protocol) protocol is responsible for assigning IP addresses to devices on a network. This allows devices to communicate with each other and access the internet.

Bluetooth is a mobile device connectivity standard that enables devices to communicate with each other using radio waves. It is commonly used for connecting devices such as smartphones, laptops, and headphones.

The HTTP (Hypertext Transfer Protocol) protocol is responsible for transferring data between a web server and a web browser. This allows users to access websites and online services.

IrDA (Infrared Data Association) is a mobile device connectivity standard that enables devices to communicate with each other using infrared light. It is commonly used for connecting devices such as smartphones, laptops, and printers.

The SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocol is responsible for encrypting data transmitted between two devices. This ensures that the data is protected from eavesdropping and unauthorized access.

Wi-Fi (Wireless Fidelity) is a mobile device connectivity standard that enables devices to communicate with each other using microwaves. It is commonly used for connecting devices to the internet and to each other.
