COMPONENTS OF EFFECTIVE BODY LANGUAGE

COMPONENTS OF EFFECTIVE BODY LANGUAGE
 The following are the components of effective body language: Facial Expressions: The facial muscles produce varying facial expressions that convey information about emotion, mood and ideas. Facial expressions are used mostly for communicating emotions. The expressions reveal the attitude of the communicator. Whether the face is sulking, smiling, frownning, yawing, it conveys some message to others. These expressions keep changing during the course of an interaction. Even though the person with the facial expressions may not be aware of it, these expressions are continually monitored by the recipient.
 Gestures:
 Gestures are one of the most frequently- observed, but least understood, cues. Most people move their hands around regularly while talking. Some of these hand movements or gestures have the same meaning across the world (for example, a clenched fist). However, many others are read differently in different cultures or countries. The meaning of the same hand movement may change depending on the situation in which it is used. People pick up these gestures by observing others. Many times, these gestures are picked up subconsciously. The following are some of the commonly-used gestures:

• Waving your hands to greet someone 
• Waving your hand to get someone’s attention
•  Pointing towards something 
• Raising your thumb to indicate something 
• Nodding your head 
• Shaking your head sideways
•  Making different signals with your fingers or hands 

Posture:

 Your posture is important, whether you are standing, sitting, lying down, running, or walking. Your posture also conveys a message to others. For instance, when you are sitting, is our back straight or bent; when you stand, are you standing erect or slouching; and so on. Such postures have the capability to indicate your 

level of comfort with the communication or situation. Keep the following points in mind for maintaining appropriate postures at all times:

• Body posture can be open or closed
•  Leaning forward indicates the listener is interested and paying attention 
• Leaning backwards demonstrates aloofness or rejection
•  A head held straight up signals a neutral attitude 
• A head down is negative and judgmental
•  A head tilted to side indicates interest 

Paralanguage: 

Paralanguage refers to the substance of your message being contradicted by the manner or attitude with which you are communicating it. Irrespective of the content of the message, the receiver can accurately read the emotions/message communicated by the tone, pitch, quality of voice, and rate of speaking. If there is a mismatch between this attitude and the message, the racier will be more likely to believe the message communicated by your attitude rather than the spoken message. When speaking, you need to be sensitive to the impact that the tone, pitch, and quality of your voice have on the interpretation of your message by the receiver. The following are important components of Paralanguage: 

Tone: Is your tone expressive and reflective? 

Inflection: Stressing on the right word and syllables to bring out the correct and enhanced message. Pitch: Is your voice too deep or pitched too high? 

Rate of speech: Do you speak too fast -- number of words per minute? 

Volume: Are you audible, too soft or too loud?

 Enunciation: Do your words have a distinct ending - especially similar sounding words?

 Fillers: Words, like “umm”, “ah” and “aaa”, are used to buy time and gather thoughts.

TYPES OF COMMUNICATION

TYPES OF COMMUNICATION

VERBAL COMMUNICATION 

Verbal skills are not only appreciated but also required during the selection process for jobs. If a person knows how to express well and can communicate confidently, he gets an automatic edge over those who cannot speak well. Verbal communication along with technical qualification is better than qualification alone.

IMPROVING VERBAL COMMUNICATION

 Here are a few ways in which we can improve verbal communication and be better equipped to word our expression: 

1. Reading aloud 
2. Thinking before speaking
3.  Taking time to prepare 
4. Organising your thought: 

• Speed- reading
•  Memory techniques 
• Mind mapping

5.Listening actively 

6.Watching out for nonverbal traps

 7.Maintaining honesty 

8.Being comprehensible and expressing your understanding

 9.Respecting everybody’s perspective

IMPORTANCE OF NON-VERBAL COMMUNICATION 

The power of non-verbal communication cannot be underestimated. The messages you send through your posture, gestures, facial expression, and movements account for 55% of what is perceived and understood by others. In fact, through your body language, you are always communicating, whether you want to or not. Non-verbal messages are the primary way with which 

you communicate your emotions. Body language and non-verbal communication comes naturally even to children, but as they get older, verbal communication begins to dominate. This is when older children and adults can lose some of the ability to understand others on such an instinctive level. Plus, the ability to communicate non-verbally varies from person to person and can be largely innate. Non-verbal communication requires self-awareness and the ability to observe others. Actions, such as sighing loudly during a lecture, and talking with your back turned to someone, may lead to miscommunication, awkwardness, and ultimately, isolation. Furthermore, non-verbal communication is sometimes connected to culture and gender, and the same ’signal’ can carry different meanings when coming from different people.

FIVE PRINCIPLES OF COMMUNICATION

FIVE PRINCIPLES OF COMMUNICATION 

1. Communication is transactional because it involves an exchange. 
2. Communication is complex due to several reasons. It is: 

1. Interactive
2.  Symbolic
3.  Personal and cultural
4.  Irreversible 
5. Circular 
6. Purposeful
7.  Impossible to duplicate

     3.Communication is unavoidable because it is impossible not to communicate.
      4.Communication is continuous because it continues to impact and influence future interactions and shapes our relationships.
        5. Communication skills can be learned because they can always be developed.

CONNECT PRINTER

CONNECT PRINTER 

Sharing the Printer

Step 1

Open the "Start" menu on the computer directly connected to the printer and click "Control Panel," "Printers and Other Hardware" and then "Printers and Faxes."

Step 2

Right-click on the printer's icon and click "Sharing." If the computer has multiple printers, pick the correct model.

Step 3

Click the "Sharing" tab and press "Share As." Type in any name for the printer to identify it to other users on the network.

Step 4

Push "Additional Drivers" if any computers on the network use a different operating system than the computer attached to the printer. Follow the prompts to pick the extra drivers to install. If you're missing any drivers for another operating system, users printing from that system will have to install them on their end instead.

Step 5

Click "Ok," or "Close" if you installed additional drivers.

Adding the Printer

Step 1

Open the "Start" menu on another computer on the network and click "Control Panel," "Printers and Other Hardware" and then "Printers and Faxes."

Step 2

Click "Add a Printer" under "Printer Tasks" and press "Next" to start the Add Printer Wizard.

Step 3

Select the option labeled "A network printer, or a printer attached to another computer" and click "Next."

Step 4

Click "Connect to this printer" and type in the location of the printer in the format "\\Computer\Printer," where "Computer" is the network name of the computer attached to the printer, and "Printer" is the name given to the printer during sharing. You can also browse the network to locate the printer instead.

Step 5

Press "Next" and wait while the setup finishes. After it completes, close the window and print a test from the shared printer to ensure it works.

Introduction to Web Application Development

Introduction to Web Application Development

Among all technologies, the Internet has been the fastest growing technology. Ever since its inception, the Internet has evolved exponentially. In the recent years, it has changed the way business is conducted. Prior to the evolution of the Internet, organizations could deliver only limited information to their prospective clients by using the existing communication media. However, with the inception of the Internet, organizations found a new medium to reach a larger range of people, irrespective of their geographical locations. Therefore, organizations increasingly became dependent on the Internet for sharing and accessing information. This resulted in changing the focus of application development from desktop applications to Web applications.

Defining Web Applications 

Web applications are programs that are executed on a Web server and accessed from a Web browser. These applications enable organizations to share and access information on the Internet and corporate intranets. This information can be accessed from anywhere, anytime. In addition, Web applications can support online commercial transactions, popularly known as e-

commerce. An online store accessed through a Web browser is an example of a Web application.

The Three Layers of a Web Application

All applications can be broken into three layers. Each layer has its own components and functionality.

an application has the following three layers:

Presentation layer: Consists of the interface through which the users interact with the application.
Business logic layer: Consists of the components of the application that control the flow of execution and communication between the presentation layer and the data layer.
Data layer: Consists of components that expose the application data stored in databases to the business logic layer.

Defining Properties

Defining Properties

Properties are a natural extension of attributes. They help a class provide a public interface for getting and setting values for private attributes, while hiding the implementation.

 A property, generally, has a private data member, accompanied by accessor functions, and is accessed as a field of a class.

 A property is usually declared private in a class and a set of public set and get accessor methods provide access to the property. The get and set methods are like any other method. They can perform any program logic, throw exceptions, be overridden, and be declared with any modifier. 

A major advantage of properties is that you can run some lines of code at the time of assigning value to a variable. For example, if you want to check the range of a value before assigning it to a variable, you can use a property.
