The principle of transformer is based on the electromagnetic induction phenomenon.
Transformers work on the principle of mutual induction between two coils.
When an alternating current flows through the primary coil, it creates a magnetic field around it.
This magnetic field induces a voltage in the secondary coil, which is proportional to the number of turns in the coil.
The voltage in the secondary coil can be stepped up...
Voltage is the measure of electric potential difference between two points in a circuit.
Voltage is measured in volts (V)
It is the force that drives electric current through a circuit
Higher voltage means more energy in the circuit
Voltage can be either AC or DC
Examples of voltage include 120V AC in household outlets and 12V DC in car batteries

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.
The OSI model stands for Open Systems Interconnection model.
It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has specific functions and communicates with the adjacent layers.
Example: When you send an email, t...

Stored procedures are precompiled SQL statements that can be saved and reused in a database.
Stored procedures can improve performance by reducing network traffic and improving security.
They can be used to encapsulate business logic and provide a consistent interface to the database.
Parameters can be passed to stored procedures, allowing for dynamic queries.
Examples of stored procedures include ones that retrieve data,
Views in SQL are virtual tables that are based on the result of an SQL statement.
Views are created using the CREATE VIEW statement.
They can be used to simplify complex queries.
They can also be used to restrict access to sensitive data.
Views are updated automatically when the underlying tables are updated.
They can be used to join multiple tables into a single view.
