Module 5: Communication Protocols

Question 1

What are the different forms of communication in our daily lives?

Answer 1

• Chatting via the internet
• Participating in a job interview

Each situation has its corresponding expected behaviors and styles.

Question 2

Before communicating, what do we establish to govern the conversation?

Answer 2

• Rules
• Agreements

These agreements guide how we interact in various communication scenarios.

Question 3

What are some key agreements to establish before communication?

Answer 3

• Method of communication
• Language to use
• Confirmation of message receipt

These agreements help ensure effective communication.

Question 4

True or false: The method of communication is irrelevant before starting a conversation.

Answer 4

FALSE

Reaching an agreement on the method used is essential before communication can begin.

Question 5

Fill in the blank: We need to confirm that our messages are _______.

Answer 5

[received]

Confirmation strategies are part of the agreements established before communication.

Question 6

Before communication can begin, one may have to teach an agreement on the language used.

Answer 6

True

Establishing a common language is essential for effective communication.

Question 7

What are the protocols that must be followed for successful communication?

Answer 7

• Identified sender and receiver
• Agreed upon method of communicating
• Common language and grammar
• Speed and timing of delivery
• Confirmation or acknowledgment requirements

These rules ensure that the message is successfully delivered and understood.

Question 8

True or false: An identified sender and receiver is not necessary for successful communication.

Answer 8

FALSE

An identified sender and receiver is one of the fundamental protocols for effective communication.

Question 9

Fill in the blank: Successful communication requires a common language and _______.

Answer 9

grammar

This ensures that both parties understand the message being conveyed.

Question 10

What is an example of an agreed upon method of communicating?

Answer 10

• Face-to-face
• Telephone
• Letter
• Photograph

These methods must be agreed upon by both the sender and receiver for effective communication.

Question 11

What aspect of communication involves the speed and timing of delivery?

Answer 11

Delivery timing

This is crucial for ensuring that the message is received in a timely manner.

Question 12

True or false: Confirmation or acknowledgment requirements are optional in communication protocols.

Answer 12

FALSE

Confirmation or acknowledgment is a necessary protocol to ensure the message was received and understood.

Question 13

The techniques used in network communications share fundamentals with what type of conversations?

Answer 13

Human conversations

Both types of communication rely on similar protocols for successful interaction.

Question 14

Why are protocols important for computers?

Answer 14

Protocols are required for computers to properly communicate across the network

They ensure that devices in a local network can ‘speak the same language’.

Question 15

What is a local network defined as?

Answer 15

An area where all hosts must ‘speak the same language’

In computer terms, this means they must share a common protocol.

Question 16

What do networking protocols define?

Answer 16

• Message format
• Message size
• Timing
• Encoding
• Encapsulation
• Message pattern

These aspects are crucial for communication over the local network.

Question 17

What is the message format in networking protocols?

Answer 17

A specific format or structure that a message must use when sent

Formats depend on the type of message and the channel used.

Question 18

What governs the size of messages communicated across the network?

Answer 18

Strict rules that can vary depending on the channel used

Long messages may need to be broken into smaller pieces for reliable delivery.

Question 19

How does timing affect network communication?

Answer 19

Determines the speed of bit transmission and when a host can send data

It also affects the total amount of data sent in one transmission.

Question 20

What is encoding in the context of network messages?

Answer 20

Converting messages into bits, which are then encoded into patterns of sounds, light waves, or electrical impulses

This depends on the network media used for transmission.

Question 21

What is encapsulation in networking?

Answer 21

The process of adding addressing information to the pieces of data that make up a message

This ensures the message is delivered to the correct application on the destination host.

Question 22

What is a request/response pattern in networking?

Answer 22

A type of message that requires acknowledgment before the next message can be sent

This is common in many networking protocols.

Question 23

True or false: Messages can be streamed across the network without concern for their delivery.

Answer 23

TRUE

Some messages do not require acknowledgment and can be sent freely.
