Edge computing is a（ ）, open IT architecture that features decentralized processing power，enabling mobile computing and Internet of Things (IoT) technologies. In edge computing,data is processed by the（ ）itself or by a local computer or server,rather than being transmitted to a data center. Edge computing enables data-stream acceleration, including real-time data processing without latency. It allows smart（ ）and devices to respond to data almost instantaneously,as its being created,eliminating lag time.This is critical for technologies such as self-driving cars,and has equally important benefits for business.Edge computing allows for efficient data processing in that large amounts of data can be processed near the source, reducing（ ）bandwidth usage.This both eliminates costs and ensures that applications can be used effectively in（ ）locations.In addition,the ability to process data without ever putting it into a public cloud adds a useful layer of security for sensitive data.
