At a minimum, a PLC will consist of a CPU used for processing and an I/O terminal that enables communication with machinery. How does a PLC work? PLCs operate by repeating a programmed loop known as a scan that
a child class is created from a parent class. For example, relationships between objects can be assigned to create a class hierarchy, which enables developers to reuse coding logic to create families of related objects.
In the process of learning Express.js, so far, we have seen ‘What is Express js? its core features, and why we should use it. Moving ahead, we will have a look at what the code looks like in Express. How does the code look like in Express.js? In the below screenshot, we can...
What is the definition of "PLC"? A Programmable Logic Controller, or PLC, is a ruggedized computer used for industrial automation. These controllers can automate a specific process, machine function, or even an entire production line. How does a PLC work?

The focus of this paper is on the development of this idea. Consequently, it does not treat any other associated topics related to Logic Programming such as constraints, abduction, etc. The idea has a long development that went through many twists in which important questions turned out to ...
An API, or application programming interface, is a set of rules and protocols that allows applications to exchange data, perform actions, and interact in a well-documented way. When a request is made—for a weather update, say—the API processes the request, executes the necessary actions, an...
If you want to know more about C programming, you can go through this C Programming Certification Course! How Does the Break Statement Work? The ‘break’ statement interrupts the flow of the loop, which results in the termination of the loop’s execution. Let’s now understand, step by ...
In a serverless model, a cloud provider runs physical servers and allocates their resources on behalf of users who can deploy code straight into production. FaaS, the more common serverless model that focuses on event-driven functions, allows developers to write custom server-side logic that is ...
But Web 3.0 focuses on the Semantic Web, while Web3 refers to the idea of decentralization. Both concepts aim to give control back to users and offer an alternative vision of the web from the current one. How does Web 3.0 benefit our lives? As the third iteration of the web, Web 3.0...
