My view on Data Communication

 


Preamble:

Electronic communication has increasingly become the norm in modern society. Text messages and emails are sent in the billions every day, and phone calls are becoming less and less the communication standard. Despite that, when someone has a legitimate concern or inquiry, they still often prefer to speak to a real, live human being rather than entering some soulless characters onto a tiny screen they carry around in their pocket. Having measures in place to ensure that your clients can speak to a real person when they want to be valuable and worthwhile. Human behavior is, in general, unpredictable. Therefore, when two humans speak to each other and wish to understand each other, they need to "speak the feedback, known as `conversation'". That is, they need to interact. Generally viewed an automatic computer, by contrast, as being completely predictable in its behavior. Hence, one-way communication from programmer to automatic computer is possible (and desirable). From this point of view, there is no need for interaction between the programmer and the automatic computer in the form of e.g., testing or debugging. Generally, this contrasted the informal world of human-to-human communication with an in-principle completely formalizable world of program-to-computer communication. By stating that an automatic computer is completely predictable, we were referring to a virtual machine, i.e., a mathematical object, not an actual physical device which does have several unpredictability’s. We were thus, from the start, discussing the formalizable parts of solving a problem by means of a computer. He was discussing programming and, while doing so, relying on his previously made assumption that programming and mathematics are effectively analogous. Generally eschewed the informal aspects of computing in report. For instance, he did not mention the transition from informal requirements to a formal specification or formal program. Nor did he mention the transition from a formal program to the execution of that program on an actual physical device. Unsurprisingly then, we were — especially in later years — perceived as somebody who focused primarily on the formal apparatus of his profession, much to the dismay of some of his contemporaries.

 

Principles of Communication

Communication is a two-way process of giving and receiving information through any number of channels. Be it speaking informally to a colleague, addressing a conference or meeting. I have always made sure that I implement these following principles before any sort of communication:

a.      Clarity: Be clear of what you speak. It should be worded in such a way that the receiver understands the same thing which you want to convey.

b.     Feedback: There should be a feedback information from the recipient to know whether he has understood the message in the same sense in which you meant it.

c.      Attention: To make communication effective, the receiver’s attention should be drawn towards message what you deliver.

d.     Time: Communication should be done at proper time so that it helps in implementing plans.

e.     Adequacy: The information communicated should be adequate and complete in all aspects.

f.       Use stories: Another way to connect with your audience and communicate your ideas is with relevant illustrative stories.

 

Human communication:

Human communication requires two or more people to communicate. The methods of communication can vary from speaking to each other in person or on the phone/mobile phone, instant messaging, emails, letters or even messages left on a colleague's desk. This omits the more old-fashioned things like fax, telex, and telegram. Businesses to cut costs have call centers some of which are manned, and others are automated. The automated ones make you press a series of keys on your phone/mobile/pc, so they are not human communication they are automated communication.

I believe that human communication involves finding that connection with another person. I feel it goes beyond just speaking and hearing words. We can communicate with a look, a gesture, and sometimes just knowing. We can speak, email and text to each other all day long and still not communicate. Communication involves more than just hearing or reading words. We need to listen, to take in, to really hear whatever is being said beyond the words being spoken. Communication is a give and take. Without the important aspect of listening, there is no communicating. Listening means caring. Caring what the other person has to say. I also believe that true listening involves empathy. We also need to understand what the other person is feeling to truly hear what they are saying. We need to connect with each other, find that common thread we all have, to open the lines of communication. We are all here on planet earth and to survive this ride, we need each other. We are sharing this human experience and I really believe that opening to each other is our only chance of survival. Lines of communication are being broken down every day with distrust and hate. Empathy and caring are integral parts of communication. So, to answer the question, what is human communication, it is communicating with an open ear and an open heart much more than with just an open mouth.

 

Establishing a Human communication:

All communication that involves people is human communication.

Communication between human can be: on to one, one to many, many to one, many to many.

Examples:
one to one - a child speaks with their mother in private

one to many - a vlogger posts a new video, many subscribers view this video

many to one - a group of professors from various universities in a country sign an open letter addressed to a politician who made some inappropriate declarations regarding the academia in that country

many to many - a politician that represents a friendship group in the Parliament addresses the PM of the country, asking them and their government to do something

Electronic communication is a type of communication that implies the use of mass media for your message to reach many people. This means that one person sends a message to many other people (one to many) or that several people send a message through a representative to a group of other people (think about communication between institutions here - one person speaks but communicates the decisions that were a result of a consultation between many people, to the people working for another institution) (many to many).

Types of Human communication:

Human communication can be subdivided into a variety of types:

Intrapersonal communication (communication with oneself):

This very basic form of information is the standard and foundation, of all thing’s communication. This communication with ourselves, showcases the process in which we think on our previous and ongoing actions, as well as what we choose to understand from other types of communications and events. Our intrapersonal communication may be shown and expressed to others by our reactions to certain outcomes, through simple acts of gestures and expressions.

Interpersonal communication (communication between two or more people):

 Communication relies heavily on understanding the processes and situations that you are in, to communicate effectively. It is more than simple behaviors and strategies, on how and what it means to communicate with another person. Interpersonal communication reflects the personality and characteristics, of a person, seen through the type of dialect, form, and content, a person chooses to communicate with. As simple as this is, interpersonal communication can only be correctly done if both persons involved in the communication, understand what it is to be human beings, and share similar qualities of what it means to be humans. It involves acts of trust and openness, as well as a sense of respect and care towards what the other person is talking about.

Nonverbal communication:

The messages we send to each other, in ways that cover the act of word-by-mouth. These actions may be done using our facial features and expressions, arms and hands, the tone of our voice, or even our very appearance can display a certain type of message.

Speech: Allowing words to make for an understanding as to what people are feeling and expressing. It allows a person to get a direct thought out to another by using their voice to create words that then turn into a sentence, which in turn then turns into a conversation to get a message across. "What is spoken or expressed, as in conversation; uttered or written words: seditious speech. A talk or public address, or a written copy of this: The senator gave a speech. The language or dialect of a nation or region: American speech. One's manner or style of speaking: the mayor's mumbling speech. The study of oral communication, speech sounds, and vocal physiology".

Conversation: Allows however many people to say words back and forth to each other that will equal into meaningful rhythm called conversation. It defines ideas between people, or teams, or groups. To have a conversation requires at least two people, making it possible to share values and interests of each person. Conversation makes it possible to getting messages across to other people, whether that be an important message or just a simple message. "Strong conversation skills will virtually guarantee that you will be better understood by most people"

Visual communication: The type of communication where it involves using your eyes that allow you to read signs, charts, graphs, and pictures that have words or phrases and or pictures showing and describing what needs to be portrayed to get information across. Using visual communication allows for people to live daily lives without constantly using your mouth to say things. A simple example is driving in the car and seeing a red sign that says stop on it, as a driver you are using visual communication to read the sign understand what is being said and stopping your car to not get into an accident. "If carried out properly, visual communication has various benefits. In the information era and fast-paced society in which time is limited, visual communication help to communicate ideas faster and better. It offers these benefits: instant conveyance, ease of understanding, cross-cultural communication, and generation of enjoyment".

Writing: What I am forming together right now is called writing where it revolves putting words together to create a sentence that flows into a sentence of meaning. Words are letters that are put together to transform a word that allows the person to understand and follow along with what is being portrayed. Writing requires us to use hands and paper to form the words and letters to create the flow of a message or conversation. Writing can also be done in the form of typing, which is what you are seeing here, forming words together on a computer. ""Writing" is the process of using symbols (letters of the alphabet, punctuation, and spaces) to communicate thoughts and ideas in a readable form".

Mail: This is in the form of postage which is in letter or package. When someone uses the post office service requiring them to send a letter that they wrote with pencil and paper, or they are using the postage service to send an object to someone out of state. Makes for an easier process to send a loved one messages or objects that do not live next to you or within a 20 min drive distance. "Material (such as letters and packages) sent or carried in a postal system". For an example a loved one is in the military and is out of state, to let them know what is going on in your life and to also ask how they are doing you send them a letter via the postal service to get that message to them at their location. Workers at the postal service get the letters and packages across states and countries.

Electronic communication:

Electronic communication refers to the exchange of data between a source and a receiver. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. The meanings of source and receiver are very simple. The device that transmits the data is known as source and the device that receives the transmitted data is known as receiver. Electronic communication aims at the transfer of data and maintenance of the data during the process but not the actual generation of the information at the source and receiver.

An electronic communication system may collect data from remote locations through data transmission circuits, and then outputs processed results to remote locations. There are electronic communication jargons to contend with such as baud rate, modems, routers, LAN, WAN, TCP/IP, ISDN, during the selection of communication systems.

As the backbone of the digital age, digital communications allow information to be communicated over copper wire, fiber-optic cable, and the air. The first wireless digital communications systems used spark-gap transmitters that used wide spectrum impulses to send single bits. In comparison, today’s modern communication systems make efficient use of spectrum to transmit large amounts of data between multiple users. They connect cell phones to the cellular network, computers to the Internet, and provide you with simple conveniences like unlocking your car doors without a key. As the number of transmitters rise, engineers will be challenged to make the most of scarce spectrum and deal with interference while meeting the increasing demand for higher data rates and reducing power consumption. It’s increasingly important for all engineers and scientists to have a fundamental understanding of RF communications principles as they incorporate wireless technology into everything from power plants to medical devices.

 

How to Establish an Electronic Communication

Electronic communication is defined as the method to transfer information from one place to another using digital signals i.e., 0 and 1.

 

In electronic communication system, the signal used to transfer information should be discrete in time and discrete in amplitude. They are also called a digital signal. For most of the time keyboard in the source of digital signal such as o and 1. But if the source is analog, first, we must convert it into a digital signal using analog to digital converter.

For example, the Internet is a digital communication system.

It will be clearer after we go through each step involved in making digital communication possible.

Source:

In a digital communication system, the source of information can be digital or analog. Let us take an analog voice signal as a source.

Input Transducer and A to D converter:

Input transducer is used to convert the original message signal such as voice into an electrical signal. Electrical signals are analog in nature, and it is the function of A to D converter to make the digital signal.

Source Encoder:

It is used to convert the data into a minimum number of bits by compressing. This also helps in the effective utilization of bandwidth available.

Channel Encoder:

It is used to introduce some redundancy bits in the information sequence to overcome the effect of noise and interference in the channel.

Digital modulator:

It is used to modulate the digital signal with a high-frequency carrier signal so it can travel through a longer distance. Also, the digital sequence of data is converted to analog signal (D/A converter) to make it travel through the channel.

Channel:

It is used to transmit the signal from transmitter to receiver. It can be wired or wireless.

Digital demodulator and A/D converter:

In this section, the received signal is demodulated and converted to a digital sequence of data.

Channel Decoder:

Its function is to complete the recover the original that may have distorted during transmission by adding some redundant bits.

Source Decoder:

The received signal is once again digitized by sampling and quantizing.

Output Transducer and D/A converter:

The received signal is converted to analog signal which is fed to the output transducer to get the original voice signal.

Output Signal:

The output signal is the desired signal (voice) after the whole process.


 

Comparison Between Human and Electronic Communication

 

Parameters of Comparison

At times, ideas conveyed can be confusing or can get delayed. 

The response is quick in electronic communication. 

Medium 

Face-to-face talks. 

It is done through the medium of the Internet or electronic gadgets. 

Requirements  

A person should be articulate enough to convey his ideas through speaking successfully. 

It is easier to communicate through electronic media as they are advanced and easier to use for everyone. 

 

 

Epilogue:

There are several ways in which one can enhance his verbal communication skills. Having ample knowledge about the topic is not enough for the listener to get a hold of the speaker’s views. The speaker should consider himself as an audience and comprehend what he wants to convey clearly. The information given should be articulate, accurate, and backed up by facts relevant to the subject. Electronic communication has changed how the world used to look; it has made businesses, language barriers, spreading across awareness, etc., more convenient. It has also made it easier to connect with your distant relatives and stay in touch with them. Communication is a two-sided contact. It is important also to receive feedback during a conversation. To respond to the speaker, the listener can use non-verbal communication methods such as nodding his head, smiling, etc. It demonstrates the importance of the speaker’s ideas.
