  • Security Software: Use updated security software to protect against malicious emails and links.
  • Education: Stay informed about common phishing tactics and how to recognize them. 

The correct resposne is (B), (C) and (D) Only

Key Points
Statement B: Words are symbols for concepts.
This statement is correct. Words act as symbols or representations for concepts, ideas, objects, etc. This symbolic nature of language allows us to communicate complex ideas and thoughts.

Statement C: Labels may be ambiguous.
This statement is correct. Labels, much like words, can be ambiguous. The ambiguity arises from different interpretations, contexts, and the inherent vagueness that some labels might carry.

Statement D: Symbols are usually understood within a group.
This statement is correct. Symbols, including words, gestures, and other forms of communication, often have meanings that are specific to a particular group or culture. These symbols are understood within the group because they share a common context and set of experiences.

 Additional Information

Statement A: Communicated meanings are always ambiguous.
This statement is incorrect. While it's true that communicated meanings can sometimes be ambiguous due to language nuances, context, and personal interpretations, it's not accurate to say they are always ambiguous. Effective communication strategies and clear context can significantly reduce ambiguity.

Statement E: Sharing of meaning is not possible in communication.
This statement is incorrect. The fundamental purpose of communication is to share meanings between individuals or groups. While perfect understanding may not always be achieved, sharing of meaning is not only possible but is a primary function of communication.

Hence, the correct answer is option 2, which includes Statements B, C, and D as true in respect of communication.

The correct answer is @.

Key Points

• The at (@) symbol is employed to separate the username and domain name within an email address. Here are 4-5 key points about it:

• Standard Email Format: The "@" symbol is a critical part of the standard email format: [email protected]. It separates the local part (username) from the domain part of the address.

• Historical Significance: The "@" symbol was chosen by Ray Tomlinson in 1971, as it was rarely used in programming languages and allowed for clarity in distinguishing between the user and the host.

• Domain Identification: The part after the "@" symbol (domain name) identifies the email server hosting the recipient's mailbox (e.g., "gmail.com").

• Internationalization: In some non-English languages, the "@" symbol is referred to by different names, such as "at" in English, "arroba" in Spanish, or "arobase" in French.

• Security: While it’s an essential part of email addresses, the "@" symbol has also become a target for spammers, who use it in phishing attempts or to generate fraudulent email addresses.

Concept:

• Point-to-Point Protocol (PPP) is a data link protocol commonly used in establishing a direct connection between two network entities or points (points here referred to as nodes, computers, hosts, etc).
• Point-to-Point Protocol (PPP) is a communication protocol of the data link layer that is used to transmit multiprotocol data between two directly connected (point-to-point) computers. It is a byte-oriented protocol that is widely used in broadband communications having heavy loads and high speeds.
• PPP is a byte-oriented protocol where each field of the frame is composed of one or more bytes.

• The main services provided by Point-to-Point Protocol are −

  • Defining the frame format of the data to be transmitted.
  • Defining the procedure of establishing a link between two points and the exchange of data.
  • Stating the method of encapsulation of network layer data in the frame.
  • Stating authentication rules of the communicating devices etc.

General Packet Radio System:

1. GPRS, or General Packet Radio Service, is a best-effort packet-switching communications protocol for cellular networks.  
2. GPRS was one of the first widely used data transfer protocols on cellular networks, first standardized in 3GPP's Release 97 in the first quarter of 1998.  Commercial cellular networks began to support GPRS in 2000.
3. GPRS is a third-generation step toward internet access.
4. GPRS is also known as GSM-IP that is a Global-System Mobile Communications Internet Protocol as it keeps the users of this system online, allows them to make voice calls, and access the internet on-the-go.

Therefore, GPRS is Wireless Communication.

The data flow between the two devices can be in simplex, half duplex and full duplex modes.

In Full duplex mode, both stations can transmit and receive at the same time.

Example: mobile phones

Important Points

Simplex

In Simplex, communication is unidirectional. Only one of the devices sends the data and the other one only receives the data.

Example: A CPU sends data while a monitor only receives data.

Half Duplex

In half duplex both the stations can transmit as well as receive but not at the

same time. When one device is sending other can only receive and vice-versa

Example: A walkie-talkie.

Key PointsWhatsApp:

• Instant messaging (IM) technology is a type of online chat allowing real-time text transmission over the Internet or another computer network.
• Messages are typically transmitted between two or more parties when each user inputs text and triggers a transmission to the recipient(s), who are all connected on a common network. 
• As of October 2019, the most used messaging apps worldwide are WhatsApp with 1.6 billion active users, the best example of instant messaging.

Hence, the correct answer is WhatsApp.

Additional InformationFacebook:

• Facebook, American online social network service that is part of the company Meta Platforms.
• Facebook was founded in 2004 by Mark Zuckerberg, Eduardo Saverin, Dustin Moskovitz, and Chris Hughes, all of whom were students at Harvard University.

Instagram: Instagram is an American photo and video sharing social networking service founded by Kevin Systrom and Mike Krieger. 

Twitter: Twitter is an American microblogging and social networking service on which users post and interact with messages known as "tweets".

Key Points

In communication, content filters are known as Gatekeepers.

Gatekeepers:

• Gatekeepers are people or systems that control the flow of information. They can be found in all areas of life, from the media to the workplace. In communication, gatekeepers can decide what information is published, who can access it, and how it is presented.

There are many different types of gatekeepers, each with a specific role. Some common examples include:

• Editors: Editors are responsible for deciding what content is published in newspapers, magazines, and other media outlets. They may also be responsible for fact-checking and editing content to ensure that it is accurate and meets the publication standards.
• Censors: Censors are responsible for blocking or removing content that is considered to be harmful or offensive. They may work for governments, businesses, or other organizations.
• Filters: Filters are software programs that block or remove certain types of content from the internet. They may be used to stop pornography, violence, or other types of content that are considered to be harmful.
• Gatekeepers play an essential role in the flow of information. They can help ensure that the public has access to accurate and relevant information while protecting them from harmful or offensive content.
• However, gatekeepers can also be used to censor information and limit people's access to it. This can be a problem in authoritarian societies where the government controls the flow of information.

The correct answer is Option 4) C, D and E only.

Key PointsInteractional model of communication:

• The interactional model of communication is a two-way process in which participants alternate positions as sender and receiver and generate meaning by sending and receiving feedback within physical and psychological contexts.
• It is associated with the concept of field of experience, which is the sum of all the experiences, knowledge, and beliefs that an individual brings to a communication situation.
• This model is also known as the convergence model because it emphasizes shared understanding and overlapping fields of experience between communicators.

Evaluation of the given statements:

A. It is best suited for new media.

• Incorrect. This is more applicable to transactional models which emphasize simultaneous feedback, not interactional ones.

B. The feedback is done in circles.

• Incorrect. While feedback is present, describing it as "circles" is inaccurate and not a standard feature.

C. It is associated with the concept of field of experience.

• Correct. A key element in Schramm’s version of the interactional model.

D. This model is also known as convergence model.

• Correct. Because it focuses on shared understanding and mutual interpretation.

E. Here the communication always happens between two familiar persons.

• Correct. It typically emphasizes interpersonal, familiar exchanges, although not an absolute rule.

Therefore, the correct answer is: Option 4) C, D and E only

Key Points

• The term "net ideologue" is often used to describe people who have a utopian view of the internet.
• They believe that the internet can solve all of the world's problems, such as poverty, inequality, and war.
• However, there are also many people who have a more critical view of the internet.
• They believe that the internet can be used to spread misinformation, hate speech, and propaganda.

The following are referred to as net ideologists:

• Nicholas Negroponte: 
  • Negroponte is a professor at the MIT Media Lab and the author of several books on the future of technology, including "Being Digital" and "A World View."
  • In his work, Negroponte argues that the internet is a powerful tool that can be used to democratize information and empower people.
• Manuel Castells:
  • ​ Castells is a Spanish sociologist and the author of several books on the information age, including "The Rise of the Network Society" and "The Power of Identity."
  • In his work, Castells argues that the internet is a new social space transforming how we live, work, and communicate.
• Algore
  • He is a former US vice president who has written about the importance of the Internet for democracy and economic development.
  • He is considered a net ideologue even though he does not have a systematic internet theory.
• Harold Innis and Marshall McLuhan are not considered to be net ideologists.
  • Innis was a Canadian economic historian who wrote about the impact of communication technologies on society.
  • McLuhan was a Canadian media theorist who popularized the idea that the medium is the message.
  • While their work is relevant to the internet, they did not specifically focus on the internet.

Hence the correct answer is C, D, and E only.  

The correct answer is Simplex Communication.

Key Points

• Simplex Communication
  • Simplex communication is a communication channel that sends information in one direction only.
  • Only one of the two devices on a link can transmit, the other can only receive.
  • It can use the entire capacity of the channel to send data in one direction.
  • Examples of simplex include radio broadcasting, television broadcasting, computer to printer communication, and keyboard to computer connections.

Key Points

•  Half-duplex Communication
  • The direction can be reversed, i.e., the station can transmit and receive the data as well.
  • Messages flow in both directions, but not at the same time.
  • The entire bandwidth of the communication channel is utilized in one direction at a time.
  • Example- Walkie-talkie
• Full-duplex Communication
  • The communication is bi-directional, i.e., the data flow in both directions.
  • Both the stations can send and receive the message simultaneously.
  • It is the fastest mode of communication between devices.
  • Example- Telephone network

According to the Oxford dictionary "communication is the imparting, conveying or exchanging of ideas, knowledge, etc., using speech, writing or any attempt to define communication has to take into consideration the idea of mutuality and commonness, an exchange, a shared environment, a social relationship among the participants and the existence of a common need. urge, aim, or goal. "
