C Programming Examples: Essential Algorithms
This document provides a collection of fundamental C programming examples, demonstrating common algorithms and data structure manipulations. Each section presents a self-contained C code snippet that you can compile and run to understand core programming concepts.
Prime Number Check
This C program determines if a given integer is a prime number. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

int num,Data Multiplexing: FDM, WDM, and TDM Explained
FDM (Frequency Division Multiplexing)
Definition: FDM is a technique where the available bandwidth of a communication channel is divided into several frequency bands. Each frequency band is assigned to a different signal or user. The signals are transmitted simultaneously but on different frequency channels, avoiding interference.
- Key Concept: Different signals are transmitted simultaneously, but each on a different frequency within the available bandwidth.
Process:
- Multiple signals (e.g., voice or
Key Communication Terms Defined
Values – Beliefs that are long-lasting; they dictate attitudes towards people.
Beliefs – A conviction.
Attitude – Causes us to act in a positive and negative way.
Interpersonal Communication – Communication involving at least two people.
Intrapersonal Communication – Communication within oneself.
Small Group Communication – Communication involving at least three people.

The Amplification Process
A distribution amplifier generates the power required to distribute the signal between all users on a network, mitigating signal losses that occur on their way from the antenna to the TV.
Modifications Required in the Amplification Process
Attenuator
An attenuator is an element that produces signal attenuation. They can be fixed or adjustable. The attenuation is constant throughout the band of the TV/SAT.
Equalizer
An equalizer attenuates

What is Entrepreneurship?
The process of identifying a business opportunity and creating a new venture to pursue that opportunity. However, when it comes to creating value, generating revenue, and achieving success when creating a new business venture, it involves taking a calculated risk. In addition, entrepreneurship is commonly associated with creativity as well as innovation.
Entrepreneurship Goals
- Creating value: Providing products or services to customers that meet their needs, solve a problem,
Fluid Mechanics: Buoyancy, Stability, and Pressure Principles
Understanding Buoyancy
Buoyancy is the upward force exerted by a fluid (liquid or gas) on an object submerged in it. This force arises from the pressure difference exerted by the fluid on different parts of the object. When an object is immersed in a fluid, the pressure at the bottom of the object is higher than the pressure at the top, causing a net upward force. This buoyant force acts opposite to the force of gravity.
According to Archimedes’ principle, the magnitude of the buoyant force on an
