2.  In our daily life we meet many people, we
come to know about many things around
the world through friends, family or anyone
else.
 Now the question is that How do we do it?
 The answer to that would be
“Communication”.
 Okay, So how do we communicate?
 There are some components that we need
for communication rather I should say
successful communication.

3. What is Communication?
 Communication is the simplest and
only way of sharing knowledge and
collecting information.

4. Components of
Communication
 Sender
 Medium
 Message
 Language/Protocol
 Receiver

5. Components of Communication
(continued..)
 Sender: Sender is someone who
sends/shares information
 Medium: Medium is termed as a path
for the data that is being shared.
 Message: Message is anything that is
being transferred between the sender
and receiver.

6. Components of Communication
(continued..)
 Language/Protocol: A Language is a
collection of symbols that are known
to both sender and receiver and have
some meaning while a Protocol is the
set of rules that apply to those
symbols as they can be in an
organized manner.
 Receiver: Receiver is someone who
receives the information that was
sent/shared earlier.

7. Significance of Language
 Communication can’t be successful if the
sender and receiver are using different
language.
 Example: Two people, one a Chinese
and one an English person both talking
to each other, neither the English man
talking in English would understand what
the Chinese person is saying nor the
person talking in Chinese would
understand what the English person is
saying, which would result in an
unsuccessful communication.

8. Communication Modes
 Human to Human
 Machine to Machine
 Human to Machine

9. Human to Human
 Human to Human communication is simple and it
doesn’t require anything special except a
language because sender and receiver in this
communication is human, air plays the role of
medium, so it’s just the language that is required.
 The language required for H2H communication is
known as Natural Language. If we talk in specific
terms then we can call English language as the
natural language because it’s spoken around the
world in most of the countries. All the human
spoken languages can be considered natural
languages.

10. Machine to Machine
 Machine to Machine communication is slightly
different from the H2H communication because it
requires two special things; a medium and a
language.
 In M2M communication wires play the role of
medium and the language that is required is
known as Machine/Binary Language.
 Machine language is a special language that is
used within the machines; it’s difficult for humans
but easy for machines to understand. In machine
language every letter, word or symbol is
represented by the combination of 0s and 1s

11. Human to Machine
 Human to Machine communication is totally
different from the other two. It requires a human
as a sender and a machine as a receiver or vice
versa.
 H2M communication requires special language
known as programming languages. Programming
languages are languages that are more like
Natural Language, (English) they are easy for
human but difficult for machine to understand.
Because a human can’t understand the machine
language and a machine can’t understand
programming languages so a translator known
as Assembler/Compiler is used to translate the
data that is being sent to & received from

12. Conclusion
 So it makes clear that we need
programming languages for
communication between the Humans
& Machines.
