Complete Summary and Solutions for Media and Communication Technology – NCERT Class XI Human Ecology and Family Sciences, Part I, Chapter 6

Full Chapter Summary & Detailed Notes - Media and Communication Technology Class 11 NCERT

Overview & Key Concepts

Chapter Goal: Understand communication as vital for human life, its types, processes, and media roles. Exam Focus: Classifications (interaction, levels, modes, senses), SMCRE model, functions. 2025 Updates: Digital media integration, AI in comm. Fun Fact: Rooted in Latin 'communis' (common). Core Idea: Effective comm creates shared understanding.
Wider Scope: Everyday impact on adolescents; sources: Diagrams (SMCRE, org chart), visuals (scenarios), activities (rural observation). Think/reflect: Tech in villages.
Expanded Content: Modern parallels like social media; point-wise for recall; add 2025 relevance like virtual comm post-pandemic.

Introduction to Communication

Definition: Process of thinking, observing, sharing feelings/ideas via mediums; stems from 'communis' for shared meaning.
Significance: Basic for survival; enhances life quality; continuous in social areas (home, school).
Tech Evolution: New gadgets weekly; popular ones sustain due to utility/cost.
Example: TV viewer frustration (one-way); baby cry response (two-way).
Expanded: Evidence: 70% verbal time; debates: Digital overload; real: 5G/AR in 2025.

Conceptual Diagram: Scenarios (Pages 73-74)

Illustrations: Teacher-student, group discussion; shows verbal/non-verbal cues.

Why This Guide Stands Out

Comprehensive: All classifications point-wise, model breakdowns; 2025 with AI ethics, analyzed for family/society impact.

Classification of Communication

By Interaction: One-way (lectures, TV); Two-way (phone, chats).
By Levels: Intra-personal (self-talk); Inter-personal (face-to-face); Group (discussions); Mass (radio/TV); Intra-org (internal hierarchy); Inter-org (govt-NGOs).
By Modes: Verbal (speaking, 70% time); Non-verbal (gestures, symbols).
By Senses: Audio (radio); Visual (posters); Audio-Visual (TV/internet); more senses = better retention (10% read vs 90% see/hear/do).
Think & Reflect: Why AV > reading? (Heritage dances engaging).
Expanded: Evidence: Table 1 senses; debates: Feedback delays in mass; real: Hybrid models 2025.

The Process of Communication

SMCRE Model: Source (initiator), Message (content), Channel (medium), Receiver (audience), Effect (feedback).
Key: Flexibility for clear understanding; market surveys as feedback ex.
Activity: Rural tech observation; news from media.
Expanded: Evidence: Who-what-when; debates: Noise barriers; real: Social media channels.

Exam Activities

List modes in rural visit (Act 1); sources in villages (Act 2); collect news (Act 3); traditional announcements (Act 4).

Summary Key Points

Types: One/two-way, levels (intra to inter-org), modes (verbal/non), senses (A/V/AV). Model: SMCRE for effective flow.

Debate: Verbal vs non-verbal effectiveness.
Ethical: Privacy in digital comm.
