Web Browser
A web browser, often shortened to browser, is an application for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers can also display content stored locally on the user's device. Browsers are used on a range of devices, including desktops, laptops, tablets, smartphones, smartwatches and consoles. As of 2024, the most used browsers worldwide are Google Chrome (~66% market share), Safari (~16%), Edge (~6%), Firefox (~3%), Samsung Internet (~2%), and Opera (~2%). As of 2023, an estimated 5.4 billion people had used a browser. Function The purpose of a web browser is to fetch content and display it on the user's device. This process begins when the user inputs a Uniform Resource Locator (URL), such as ''https://en.wikipedia.org/'', into the browser's address bar. Virtually all URLs on the Web start with either ''http:'' or ''h ...

Modbus
Modbus (or MODBUS) is a client/server data communications protocol in the application layer. It was originally designed for use with programmable logic controllers (PLCs), but has become a ''de facto'' standardization, standard communication protocol for communication between industrial Electronics, electronic devices in a wide range of Bus (computing), buses and networks. Modbus is popular in industrial environments because it is openly published and royalty-free. It was developed for industrial applications, is relatively easy to deploy and maintain compared to other standards, and places few restrictions on the format of the data to be transmitted. The Modbus protocol uses serial port, serial communication lines, Ethernet, or the Internet protocol suite as a transport layer. Modbus supports communication to and from multiple devices connected to the same cable or Ethernet network. For example, there can be a device that measures temperature and another device to measure humi ...

Edge Computing
Edge computing is a distributed computing model that brings computation and data storage closer to the sources of data. More broadly, it refers to any design that pushes computation physically closer to a user, so as to reduce the Latency (engineering), latency compared to when an application runs on a centralized data centre. The term began being used in the 1990s to describe Content Delivery Network, content delivery networks—these were used to deliver website and video content from servers located near users. In the early 2000s, these systems expanded their scope to hosting other applications, leading to early edge computing services. These services could do things like find dealers, manage shopping carts, gather real-time data, and place ads. The Internet of Things (IoT), where devices are connected to the internet, is often linked with edge computing. Definition Edge computing involves running computer programs that deliver quick responses Locality of reference, close to ...

Industrial Internet Of Things
The industrial internet of things (IIoT) refers to interconnected sensors, instruments, and other devices networked together with computers' industrial applications, including manufacturing and energy management. This connectivity allows for data collection, exchange, and analysis, potentially facilitating improvements in productivity and efficiency as well as other economic benefits. The IIoT is an evolution of a distributed control system (DCS) that allows for a higher degree of automation by using cloud computing to refine and optimize the process controls. Overview The IIoT is enabled by technologies such as cybersecurity, cloud computing, edge computing, mobile technologies, machine-to-machine, 3D printing, advanced robotics, big data, Internet of things, RFID technology, and cognitive computing. Five of the most important ones are described below: *Cyber-physical systems (CPS): the basic technology platform for Internet of things, IoT and IIoT and therefore the main enab ...

OpenAPI Specification
The OpenAPI Specification, previously known as the Swagger Specification, is a Specification (technical standard), specification for a Machine-readable medium, machine-readable interface definition language for describing, producing, consuming and visualizing Web API, web services. Originally developed to support the Swagger (software), Swagger framework, it became a separate project in 2015, overseen by the OpenAPI Initiative, an open-source collaboration project of the Linux Foundation. An OpenAPI Description (OAD) represents a formal description of an API that tools can use to generate code, documentation, test cases, and more. History Swagger (software), Swagger development began in early 2010 by Tony Tam, who was working at online dictionary company Wordnik. In March 2015, SmartBear Software acquired the open-source Swagger API specification from Reverb Technologies, Wordnik's parent company. In November 2015, SmartBear announced that it was donating the Swagger specificat ...

Command-line Tool
A console application or command-line program is a computer program (applications or utilities) designed to be used via a text-only user interface. A console application can be used with a computer terminal, a system console, or a terminal emulator included with a graphical user interface (GUI) operating system, such as the Windows Console in Microsoft Windows, the Terminal in macOS, and xterm in the X Window System on Unix-like systems. Console applications can be run from a command-line shell. Overview A user typically interacts with a console application using only a keyboard and display screen, as opposed to GUI applications, which normally require the use of a mouse or other pointing device. Many console applications such as command line interpreters are command line tools, but numerous text-based user interface (TUI) programs also exist. As the speed and ease-of-use of GUIs applications have improved over time, the use of console applications has greatly diminished ...

User Interface
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and Unit operation, process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide mi ...
