7. Introduction
 Communication is the essence of human
civilization.
 The development of communication
technology has changed the means and modes
of communication.
 Now people communicate through e-mails,
mobiles, video calls, etc.
 The main ides is to transfer the data or
information at high speed.

8. Introduction to Communication Technology
 Communication technology refers to the
tools, systems, and processes used to
transmit, receive, and share information
between individuals, groups, or
machines.

9. Introduction to Communication Technology
It combines principles of
communication with advances in
technology to make information
exchange faster, easier, and more
effective.

10.  From the invention of the printing press and the
telegraph to the rise of mobile phones, satellites,
and the internet, communication technology has
transformed the way people interact and access
knowledge. Today, it plays a central role in
education, business, healthcare, governance,
entertainment, and social connections.
Introduction to Communication Technology

11. Core communication technology
 At its core, communication technology involves
three main elements:
 The Medium – devices or channels such as phones,
radio, TV, or digital platforms.
 The Message – the information being shared,
whether text, sound, video, or data.
 The Audience – the individuals or systems
receiving and interpreting the message.

12.  ……………………………………………………………………………
……………………………….refers to the use of technical
tools, networks, and systems to process, store,
transmit, and receive information efficiently
across different media.

13. Components of Communication Technology
Activity 1:
………..The origin of the message.
……….. Data, text, audio, video, or signals.
……….. Wired (fiber optics, cables) or wireless (Wi-Fi, cellular, satellite).
……….. End user or system.
……….. Errors, delays, or distortions in transmission.

14. Components of Communication Technology
1. Sender (Source)
2. Message
3. Medium/Channel
4. Receiver
5. Feedback & Noise
………..The origin of the message.
……….. Data, text, audio, video, or signals.
……….. Wired (fiber optics, cables) or wireless (Wi-Fi, cellular, satellite).
……….. End user or system.
……….. Errors, delays, or distortions in transmission.

15. Modern Applications
 Telecommunications: Mobile phones, VoIP.
 Business Communication: Emails, video
conferencing, collaborative platforms (Zoom,
Slack, Teams).
 Social Media & Content Sharing: Facebook, X,
TikTok, YouTube.
 E-Governance & Education: Digital platforms, e-
learning.
 Emerging Trends: 5G, Blockchain communication,
AI chatbots, Metaverse communication.

16. Key Difference (in short):
 Communication Technology = Focus on communication tools &
channels (how we connect).
 ICT = A broader field that includes IT (information systems,
computing) + CT (communication tools).
 👉 In other words:
CT is a subset of ICT.

19. LocalSend is a free, open-source, cross-platform file sharing tool that
allows you to share files to nearby devices.

21. DATA
 The word data is the plural of datum, though
data is commonly used to represent both
singular and plural forms.
 Data is the measurement of the attributes or
characteristics of entities like people, places,
things, and events.
 The measurements are usually represented by
symbols like numbers, alphabetical, and other
characters.
 Data can be numeric, text, image or voice.

23. INFORMATION
 Information refers to processed data. It is
meaningful and helps in making decisions.
 A company launches a new product, say, a face
wash and gives a pound of 5ml free of cost to
100 families. After a week, a survey result
decides how to proceed with the marketing
campaign.
 The meterological department collects the
weather measurements data, which is then
processed into a chart for making a weather
forecast.

25. MULTIMEDIA
 Multimedia can be defined as an
integration of sound, animation, still
images, and video along with computing
technology.
 Multimedia files occupy more space
due to the sound and picture files.
 Multimedia Software is available on CD-
ROMs.

26. MULTIMEDIA
 Uses of Multimedia:
1) Adding Sound Files
2) Creating 3-D effects in different ways
3) Learning a new language by interacting using
the written and spoken words
4) Creating animated birthday cards

27. MULTIMEDIA

of Multimedia:
1) Interactive
2) Entertainment
3) Information System
 Multimedia Requirements :
1) CPU
2) RAM
3) Audio
4) Video
5) Hard Disk.

29. NETWORKING
 A computer network is a set of computers connected
together for the purpose of sharing resources.
 There are two terms that are commonly associated
with networking – servers and workstations.
 Servers - A server is a computer program or a
machine that waits for requests from other machines
or software (clients) and responds to them.
 Workstation – It is the computer that is directly used by
some one to do work. A workstation can also act as a
server when file or printer sharing is enabled.

30. NETWORKING

Networking :
1) Network Interface Card (NIC)
2) Registered Jack-45 (RJ-45)
3) Hub
4) Switch
5) Modem ( Modulator-Demodulator)
6)Router

31. NETWORKING
 The Advantages of
Networking are :
1) Resource Sharing
2) Reliability
3) Financial benefits
4) Better
Communication
5) Access to a remote
database
 Types of Networks:
1) Personal Area
Network (PAN)
2) Local Area
Network (LAN)
3) Metropolitan Area
Network (MAN)
4) Wide Area Network
(WAN)

32. Case Study Discussion
 Present a short case: “During the
COVID-19 pandemic, online learning
became the main mode of education.
What were the advantages and
challenges?”
