The document discusses fog computing, which extends cloud computing to the edge of networks. Fog computing facilitates compute, storage, and networking services between end devices and cloud data centers. It helps address issues with cloud computing like latency, bandwidth, and processing huge volumes of data from IoT devices. Fog computing provides advantages like lower latency, better security and privacy, and support for mobility. Potential applications of fog computing include smart homes, grids, vehicles, cities, and health data management.

3. Introduction
• Fog computing is a term created by Cisco that
refers to extending cloud computing to the
edge of an enterprise network.
• It is also known as Edge computing or fogging.
• Fog computing facilitates the operations of
compute, storage and networking services
between end devices and cloud computing
data centers.

4. Why Fog Computing?
• There are several issues in cloud computing of
which the major ones are volume, latency and
bandwidth.
• Current cloud model is unable to process huge
volume of data. Private firms, factories,
airplane companies, healthcare sectors
produces enormous amount of data every day.
• To overcome such situations Fog can be used
as a middle layer between device and cloud.
