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

Terrestrial Television Amplification Systems
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

Negotiation
Negotiation is the mutual arrangement and discussion of the terms of a transaction or agreement.
The Types of Negotiation
Distributive negotiation occurs when one side wins (or, more accurately, gains) and the other party loses. This is called a zero-sum game in Game Theory.
Integrative negotiations are when both sides win, often achieved through compromising.
Pyrrhic negotiations occur when both sides lose. Cases include situations where sides want to appear strong and do not want the other
