Edge computing is a method of delivering intelligent services at the network edge by combining the key technologies of networks, processing, storage, and applications. This technique facilitates meeting the critical criteria of the digital business for agile connectivity, security, data optimization, real-time services, and privacy protection close to the location of devices.	[52]
Edge computing consists of techniques that enable computation at the network’s edge, close to the source of production of the information. In edge computing, the node not only gathers information but also generates it.	[53]
Edge computing is a recent trend of cloud computing wherein major storage and computational resources, alternatively termed as cloudlets, micro data centers, are located close to the end devices or sensors at the network edge.	[54]
Edge computing is a technology that performs computations near the source of information rather than sending them to a centralized processing system to capitalize in terms of speed, transmission time, and effectiveness.	[55]
Edge computing helps eliminate the necessity for centralized data processing by bringing the device’s computational capability close to the source of information. This allows fast data transport and improves the effectiveness of the computing process.	[56]
Edge computing is a new processing paradigm that brings computing power and storage to the network’s edge. It provides advanced analysis combined with cloud services.	[57]
