Local Area Network (LAN)

a computer network that covers a small area such as a home, small business, or department within a large corporation

Wide Area Network (WAN)

a collection of LANs that provides inter-LAN and internet connectivity for networks over long distance

Wireless Network

computer networks that use electromagnetic waves instead of wires in order to carry signals over the various parts of the network

the cloud

a collection of data centers or groups of connected servers that are used to store and analyze data, provide access to on-line applications, and provide backup services for personal and corporate use

the edge

a term that refers to the physical "edge" of a corporate network

fog computing

servers and computer programs, which are located at the edge of a business or corporate network, that allow the local data to be preprocessed for immediate use.

Internet of Things (IoT)

the connection of millions of smart devices and sensors connected to the internet

home gateway

a device that acts as a local connection center to IoT smart devices

artificial intelligence

a branch of computer science dealing with the simulation of intelligent behavior in computers which implies that smart devices can think on their own
