A PLC ( Programmable Logic Controller) is a ruggedized computer used for industrial automation. These controllers can automate a specific process. Learn about configuration, programming, implementation, and more.
A programmable logic controller (PLC) is a small, modular,solid-statecomputer with customized instructions for performing a particular task. PLCs, used in various industrial control systems (ICSes), have primarily replaced mechanical relays, drum sequencers and cam timers. PLCs have revolutionized t...
A programmable logic array (PLA) is a type of logic device that can be programmed to implement various kinds of combinational logic circuits. The device has a number of AND and OR gates which are linked together to give output or further combined with more gates or logic circuits. Advertise...
1. As a verb, to program a computer is writing instructions, statements, or commands that instruct the computer how to process data. There are several programming languages used to program a computer. Using one of these programming languages a programmer can write code to instruct the computer ...
To handle proof theory, our institutions use an extension of traditional categorical logic with sets of sentences as objects instead of single sentences, and with morphisms representing proofs as usual. A natural equivalence relation on institutions is defined such that its equivalence classes are ...
What is Logic(什么是逻辑)Logic This article is about reasoning and its study. For other uses, see Logic (disambiguation).Logic (from the Ancient Greek: λογική, logike)[1] is the use and study of valid reasoning.[2][3] The study of logic features most prominently in the ...
An ad hominem fallacy is one that attempts to invalidate an opponent’s position based on a personal trait or fact about the opponent rather than through logic. Example:Katherine is a bad choice for mayor because she didn’t grow up in this town. ...

The program flowchart is a data flow that shows the data flow while writing a program or algorithm. It allows the user to explain the process quickly as they collaborate with others. These programming flowcharts also analyze the logic behind the program to process the code of the programming....
What is a logic bomb? A logic bomb is a string of maliciouscodeinserted intentionally into a program to harm a network when certain conditions are met. The term comes from the idea that the code "explodes" when triggered by a specific event, such as a certain date or time, the deletion...
