In online marketing, a shopping cart is a piece of e-commerce software on a web server that allows visitors to an Internet site to select items for eventual purchase, analogous to the American English term "shopping cart." In British English, it is generally known as a shopping basket, almost exclusively shortened on websites to "basket.".

E-commerce is a transaction of buying or selling online.

Electronic commerce draws on technologies such as mobile commerce, electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems.

Modern electronic commerce typically uses the World Wide Web for at least one part of the transaction's life cycle although it may also use other technologies such as e-mail.

Online shopping is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser.

Consumers find a product of interest by visiting the website of the retailer directly or by searching among alternative vendors using a shopping search engine, which displays the same product's availability and pricing at different e-retailers.

As of 2016, customers can shop online using a range of different computers and devices, including desktop computers, laptops, tablet computers and smartphones.

Home automation or smart home (also known as domotics) is building automation for the home.

It involves the control and automation of lighting, heating (such as smart thermostats), ventilation, air conditioning (HVAC), and security, as well as home appliances such as washer/dryers, ovens or refrigerators/freezers.

Wi-Fi is often used for remote monitoring and control.

Home devices, when remotely monitored and controlled via the Internet, are an important constituent of the Internet of Things.

Modern systems generally consist of switches and sensors connected to a central hub sometimes called a "gateway" from which the system is controlled with a user interface that is interacted either with a wall-mounted terminal, mobile phone software, tablet computer or a web interface, often but not always via Internet cloud services.

An online marketplace (or online e-commerce marketplace) is a type of e-commerce site where product or service information is provided by multiple third parties, whereas transactions are processed by the marketplace operator.

Online marketplaces are the primary type of multichannel ecommerce and can be described as a "simple and convenient portal" to streamline the production process.
