PID stands for Proportional-Integral-Derivative. It is a control algorithm used in systems to maintain a desired output.
PID is a feedback control mechanism that continuously calculates an error value based on the difference between a desired setpoint and the actual output of a system.
The Proportional term adjusts the output proportionally to the error value.
The Integral term sums up the error over time to eliminate ste...
A closed loop is a control system where the output is fed back to the input for continuous monitoring and adjustment.
In a closed loop system, the output is compared to a desired value and adjustments are made to bring the output closer to the desired value.
Examples of closed loop systems include thermostat-controlled heating systems and cruise control in cars.
Closed loop systems are used to maintain stability, accuracy...

LVM (Logical Volume Manager) is a tool used in Linux to manage storage by creating logical volumes from physical volumes.
LVM allows for dynamic resizing of logical volumes without needing to unmount the filesystem.
It consists of physical volumes (PVs), volume groups (VGs), and logical volumes (LVs).
PVs are physical storage devices like hard drives or partitions, VGs are a collection of PVs, and LVs are the virtual part...
Technical quotation related to PLC
Types of gates in logic are basic building blocks of digital circuits.
AND gate: outputs true only when all inputs are true (e.g. A AND B)
OR gate: outputs true when at least one input is true (e.g. A OR B)
NOT gate: inverts the input (e.g. NOT A)
NAND gate: combination of AND gate followed by NOT gate
NOR gate: combination of OR gate followed by NOT gate
XOR gate: outputs true when inputs are different (e.g. A XOR B)
