Full stack refers to the complete set of technologies used in web development, covering both front-end and back-end aspects.
Front-end technologies include HTML, CSS, and JavaScript frameworks like React or Angular.
Back-end technologies involve server-side languages like Node.js, Python, or Ruby.
Databases such as MySQL, MongoDB, or PostgreSQL are essential for data storage.
Full stack developers can work on both cli...
Insertion Sort is a simple sorting algorithm that builds a sorted array one element at a time.
Works by dividing the array into a sorted and an unsorted part.
Starts with the second element, compares it to the first, and inserts it in the correct position.
Repeats this process for each subsequent element until the entire array is sorted.
Example: For array [5, 2, 9, 1], it sorts as follows: [5], [2, 5], [2, 5, 9], [1,...
You can swap two variables without a third variable using arithmetic operations or bitwise XOR, maintaining their values.
Using Arithmetic: a = a + b; b = a - b; a = a - b; // This method uses addition and subtraction to swap values.
Using Bitwise XOR: a = a ^ b; b = a ^ b; a = a ^ b; // This method uses the XOR operation to swap values without a third variable.
No Additional Memory: Both methods achieve the swap wit...

1. Cause-and-Effect Diagram: Also known as a fishbone diagram, it helps identify root causes of a problem. Example: Analyzing reasons for product defects.
2. Check Sheet: A structured form for collecting and analyzing data. Example: Tracking the number of defects in a production line.
3. Control...
Flip-flops are basic digital memory circuits used in electronics for storing binary data.
Types: Common types include SR, D, JK, and T flip-flops.
SR Flip-Flop: Set-Reset flip-flop, used for basic memory storage.
D Flip-Flop: Data flip-flop, captures the value of the input at a clock edge.
JK Flip-Flop: Combines features of SR and D, can toggle output.
T Flip-Flop: Toggle flip-flop, changes state on each clock pulse.
Modulation is the process of varying a carrier signal's properties to encode information for transmission.
Modulation can change amplitude, frequency, or phase of the carrier signal.
Amplitude Modulation (AM) is used in AM radio broadcasting.
Frequency Modulation (FM) is commonly used in FM radio and television.
Phase Shift Keying (PSK) is used in digital communication systems.
Frequency is the number of occurrences of a repeating event per unit time, typically measured in Hertz (Hz).
Frequency is measured in Hertz (Hz), where 1 Hz equals one cycle per second.
In electronics, frequency determines the behavior of circuits, such as in oscillators and filters.
Examples include audio frequencies (20 Hz to 20 kHz) for sound and radio frequencies (kHz to GHz) for communication.
Higher frequencies ...
CNC machine stands for Computer Numerical Control machine, which is a computer-controlled manufacturing tool used for cutting, milling, drilling, and shaping various materials.
CNC machines use computer programs to control the movement of the cutting tool or workpiece, resulting in precise and accurate machining.
They are commonly used in industries such as automotive, aerospace, and electronics for mass production ...

RPM stands for Revolutions Per Minute, a unit of measurement used to describe the speed at which an object rotates around a fixed axis.
RPM is commonly used to measure the speed of engines, motors, and other rotating machinery.
It indicates how many complete revolutions a rotating object makes in one minute.
For example, a car engine may have an RPM range of 1000 to 6000, indicating the speed at which the engine is runnin...
Newton's 3rd Law states that for every action, there is an equal and opposite reaction.
Action and reaction forces are equal in magnitude but opposite in direction.
Example: When you push against a wall, the wall pushes back with equal force.
Example: A rocket propels forward by expelling gas backward.
This law explains various phenomena, from walking to swimming.
UTM stands for Unified Threat Management, a comprehensive security solution that combines multiple security features into a single platform.
UTM integrates various security functions such as firewall, intrusion detection/prevention, antivirus, content filtering, and VPN.
It provides a centralized approach to managing security policies and monitoring network traffic.
UTM appliances are commonly used in businesses to protec...
