4G
Definition:
4G stands for 4th Generation and represents a network standard for mobile phone communication. 4G is used to transmit advanced data services such as Internet and streaming video from mobile phones. 4G is considered the first standard to bring near (and in some cases better) broadband speed to the mobile phone, making a big jump from current and previous speeds available with 3G.

UPS
An Uninterruptible Power Supply, or UPS, is a device that can supply battery power to any electrical devices plugged into it. You will typically find a UPS connected to a computer or server to keep it running during a power outage. Battery time varies for each UPS and is usually proportional to the price tag. A smaller, home-based UPS usually provides enough battery power to sound an alarm and give a person enough time to save open files and safely shut down his or her computer. Conversely, an enterprise UPS will provide enough battery power for an entire room full of servers to run for an extended period of time.
