✅ 1. Define Cyber Security. Why is it important?
Cyber Security is the practice of protecting computers, networks, and data from unauthorized access, attacks, or damage.
Importance:
Protects sensitive data
Prevents financial loss
Ensures privacy and safe online activities
✅ 2. What is Social Engineering? Explain with examples.
Social Engineering is manipulating people to steal confidential information.
Example: Phishing emails, fake customer-care calls asking for OTP, impersonation scams.

1) Amplitude Modulation (AM)- Amplitude Modulation is a method in which the amplitude of a high-frequency carrier wave is varied in accordance with the instantaneous value of the message signal. The carrier’s frequency and phase remain unchanged. AM is simple to generate and demodulate, making it suitable for broadcasting. However, it is less efficient and more prone to noise because noise mainly affects amplitude. 2) Frequency Modulation (FM)-Frequency Modulation is an angle-modulation technique...
Modulation is the process of varying a property of a high-frequency carrier signal (such as its amplitude, frequency, or phase) in accordance with the information signal, like voice, music, or data. Common types include: AM (Amplitude Modulation) – carrier amplitude varies FM (Frequency Modulation) – carrier frequency varies and Phase modulation. Need for Modulation- 1) To Transmit Signals Over Long Distances-Low-frequency message signals (like human voice at ~3 kHz) cannot travel far. A high-...
Construction: A Lithium-ion battery consists of the following components://Anode (Negative Electrode): Made of graphite or carbon-based material that can intercalate lithium ions//Cathode (Positive Electrode): Composed of lithium metal oxide such as LiCoO2 (Lithium Cobalt Oxide), LiMn2O4 (Lithium Manganese Oxide), or

Organ donation, can be split into 3 categories living, after brain death, and after circulatory death donation.
Organ donation replaces a diseased organ.
Around 1,800 people are on the waitlist, with approximately 14,000 additional people on dialysis who could benefit from a kidney transplant. (In Aus)

📝 Accounting Treatment of Amalgamation as per AS-14
Accounting Standard (AS) 14, 'Accounting for Amalgamations,' issued by the Institute of Chartered Accountants of India (ICAI), prescribes the accounting treatment for amalgamations. The standard classifies amalgamations into two types, which determines the appropriate accounting method to be used by the Transferee Company (the acquiring/new company).
I. Types of Amalgamation
AS-14 distinguishes between two types of amalgamation based on the conditions
Absolutely! ICDS is a crucial program in India focused on holistic child development.
👶 What is ICDS? (Meaning)
ICDS stands for Integrated Child Development Services. It is a flagship social welfare scheme of the Government of India launched in 1975.
It is one of the world's largest community-based programs that aims to provide a package of services for the holistic development of children under the age of six, along with their mothers. The services are delivered primarily through a network of grassroots
Creating GUI applications using AWT involves setting up a top-level container, adding components, arranging them with a Layout Manager, and then making the container visible.
Here is a step-by-step guide to creating a simple AWT application (specifically, a Frame):
🏗️ Steps to Create an AWT Application
1. Choose a Top-Level Container
The application needs a primary window to hold all the components. The most common choice is the Frame class, which provides a title bar, borders, and window controls.
Modulation is the process of varying a high-frequency carrier signal according to the low-frequency message (baseband) signal.
To reduce the size of antenna (Antenna height = λ/4, without modulation antenna becomes hundreds of meters).
To avoid mixing of signals (different stations use different carrier frequencies).
To increase the range of communication (HF carriers travel longer distances).
For multiplexing (many signals can
