Business & Communications


Business & Communications

Businesses continue to grow, expand and evolve as our social, political and economic structures change form. As these transformations take place, it becomes increasingly important to improve upon the structures and maneuverability of businesses.The field of business and communication is a field in which professionals work to positively affect the course of businesses and to secure businesses stability, prosperity and competitiveness in an increasingly competitive and evolving world.


The word “communication” derived from the Latin word ‘communicare’ that means to impart, to participate, to share or to make common. It is a process of exchange of facts, ideas, opinions and as a means that individual or organization share meaning and understanding with one another. In other words, it is a transmission and interacting the facts, ideas, opinion, feeling and attitudes. It is the ability of mankind to communicate across barriers and beyond boundaries that has ushered the progress of mankind. It is the ability of fostering speedy and effective communication around the world that has shrunk the world and made ‘globalization’ a reality. Communication had a vital role to play in ensuring that people belonging to a particular country or a culture or linguistic group interact with and relate to people belonging to other countries or culture or linguistic group. Communication adds meaning to human life. It helps to build relationship and fosters love and understanding. It enriches our knowledge of the universe and makes living worthwhile.

The term business communication is used for all messages that we send and receive for official purpose like running a business, managing an organization, conducting the formal affairs of a voluntary organization and so on. Business communication is marked by formality as against personal and social communication. The success of any business to a large extent depends on efficient and effective communication. It takes place among business entities, in market and market places, within organizations and between various group of employees, owners and employees, buyers and sellers, service providers and customers, sales persons and prospects and also between people within the organization and the press persons. All such communication impacts business. Done with care, such communication can promote business interests. Otherwise, it will portray the organization in poor light and may adversely affect the business interest. Communication is the life blood of any organization and its main purpose is to effect change to influence action. In any organization the main problem is of maintaining effective communication process. The management problem generally results in poor communication. Serious mistakes are made because orders are misunderstood. The basic problem in communication is that the meaning which is actually understood may not be what the other intended to send. It must be realised that the speaker and the listener are two separate individuals having their own limitations and number of things may happen to distort the message that pass between them. When people within the organization communicate with each other, it is internal communication. They do so to work as a team and realise the common goals. It could be official or unofficial. Modes of internal communication include face-to-face and written communication. Memos, reports, office order, circular, fax, video conferencing, meeting etc. are the examples of internal communication. When people in the organization communicate with anyone outside the organization it is called external communication. These people may be clients or customers, dealers or distributors, media, government, general public etc. are the examples of external communication.


Communication may be defined as interchange of thought or information between two or more persons to bring about mutual understanding and desired action. It is the information exchange by words or symbols. It is the exchange of facts, ideas and viewpoints which bring about commonness of interest, purpose and efforts. American Management Association defines, ‘Communication is any behaviour that results in an exchange of meaning’. Peter Little defines communication as, ‘Communication is the process by which information is transmitted between individuals and/or organizations so that an understanding response result’. Newman and Summer Jr. state that, ‘Communication is an exchange of facts, ideas, opinions or emotions by two or more persons’. According to Keith Davis, ‘The process of passing the information and understanding from one person to another. It is essentially a bridge of meaning between the people. By using the bridge a person can safely across the river of misunderstanding’.
Louis A. Allen defines, ‘Communication is the sum total of all the things that a person does, when he wants to create an understanding in the mind of another. It involves a systematic and continuous process of telling, listening and understanding’. Therefore, the main purpose of communication is to inform, or to bring around to a certain point of view or to elicit action.


1. For instruction: The instructive function unvarying and importantly deals with the commanding nature. It is more or less of directive nature. Under this, the communicator transmits with necessary directives and guidance to the next level, so as to enable them to accomplish his particular tasks. In this, instructions basically flow from top to the lower level.
2. For integration: It is consolidated function under which integration of activities is endeavoured. The integration function of communication mainly involves to bring about inter-relationship among the various functions of the business organization. It helps in the unification of different management functions.
3. For information: The purposes or function of communication in an organization is to inform the individual or group about the particular task or company policies and procedures etc. Top management informs policies to the lower level through the middle level. In turn, the lower level informs the top level the reaction through the middle level. Information can flow vertically, horizontally and diagonally across the organization. Becoming informed or inform others is the main purpose of communication.
4. For evaluation: Examination of activities to form an idea or judgement of the worth of task is achieved through communication. Communication is a tool to appraise the individual or team, their contribution to the organization. Evaluating one’s own inputs or other’s outputs or some ideological scheme demands an adequate and effective communication process.
5. For direction: Communication is necessary to issue directions by the top management or manager to the lower level. Employee can perform better when he is directed by his senior. Directing others may be communicated either orally or in writing. An order may be common order, request order or implied order.
6. For teaching: The importance of personal safety on the job has been greatly recognized. A complete communication process is required to teach and educate workers about personal safety on the jobs. This communication helps the workers to avert accidents, risk etc. and avoid cost, procedures etc.
7. For influencing: A complete communication process is necessary in influencing others or being influenced. The individual having potential to influence others can easily persuade others. It implies the provision of feedback which tells the effect of communication.
8. For image building: A business enterprise cannot isolate from the rest of the society. There is interrelationship and interdependence between the society and an enterprise operating in the society. Goodwill and confidence are necessarily created among the public. It can be done by the communication with the different media, which has to project the image of the firm in the society. Through an effective external communication system, an enterprise has to inform the society about its goals, activities, progress and social responsibility.
9. For employees orientation: When a new employee enter into the organization at that time he or she will be unknown to the organization programs, policies, culture etc. Communication helps to make people acquainted with the co-employees, superior and with the policies, objectives, rules and regulations of the organization.

10. Other: Effective decision-making is possible when required and adequate information is supplied to the decision-maker. Effective communication helps the process of decisionmaking. In general, everyone in the organization has to provide with necessary information so as to enable to discharge tasks effectively and efficiently.


The transmission of sender’s ideas to the receiver and the receiver’s feedback or reaction to the sender constitute the communication cycle. The process of communication begins when one person (the sender) wants to transmit a fact, idea, opinion or other information to someone else (the receiver). This facts, idea or opinion has meaning to the sender. The next step is translating or converting the message into a language which reflects the idea. That is the message must be encoded. The encoding process is influenced by content of the message, the familiarity of sender and receiver and other situation of factors. After the message has been encoded, it is transmitted through the appropriate channel or medium. Common channel in organization includes meetings, reports, memorandums, letters, e-mail, fax and telephone calls. When the message is received, it is decoded, by the receiver and gives feedback to the sender as the conformation about the particular message has been carefully understand or not.

The process of communication involves the following elements:
1. Sender or transmitter: The person who desires to convey the message is known as sender. Sender initiates the message and changes the behaviour of the receiver.
2. Message: It is a subject matter of any communication. It may involve any fact, idea, opinion or information. It must exist in the mind of the sender if communication is to take place.
3. Encoding: The communicator of the information organises his idea into series of symbols (words, signs, etc.) which, he feels will communicate to the intended receiver or receivers.
4. Communication channel: The sender has to select the channel for sending the information. Communication channel is the media through which the message passes. It is the link that connects the sender and the receiver.
5. Receiver: The person who receives the message is called receiver or receiver is the person to whom the particular message is sent by the transmitter. The communication process is incomplete without the existence of receiver of the message. It is a receiver who receives and tries to understand the message.
6. Decoding: Decoding is the process of interpretation of an encoded message into the understandable meaning. Decoding helps the receiver to drive meaning from the message.
7. Feedback: Communication is an exchange process. For the exchange to be complete the information must go back to whom from where it started (or sender), so that he can know the reaction of the receiver. The reaction or response of the receiver is known as feedback.
8. Brain drain: On whole process there is a possibility of misunderstandings at any level and is called brain drain. It may arise on sender side if they do not choose the adequate medium for delivery of message, by using default channel and it may also arise when receiver does not properly decode the message. In other words, we can say that it is breakdown of cycle at any level.

Information technology

Information technology (IT) is the application of computers and internet to store, retrieve, transmit, and manipulate data, or an information often in the context of a business or other enterprise.IT is considered a subset of information and communications technology (ICT). In 2012, Zuppo proposed an ICT hierarchy where each hierarchy level “contain some degree of commonality in that they are related to technologies that facilitate the transfer of information and various types of electronically mediated communications. Business/IT was one level of the ICT hierarchy.
The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several industries are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, engineering, healthcare, e-commerce, and computer services.

A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized to model aspects of reality in a way that supports processes requiring information, such as modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, Sybase, SAP HANA, and IBM DB2. A database is not generally portable across different DBMSs, but different DBMS can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language. Sometimes a DBMS is loosely referred to as a ‘database’.

Data storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers.The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but larger and cheaper options farther away. Generally the fast volatile technologies (which lose data when off power) are referred to as “memory”, while slower persistent technologies are referred to as “storage”; however, “memory” is sometimes also used when referring to persistent storage.
In the Von Neumann architecture, the CPU consists of two main parts: The control unit and the arithmetic / logic unit (ALU). The former controls the flow of data between the CPU and memory, while the latter performs arithmetic and logical operations on data.

Data retrieval
Data retrieval means obtaining data from a database management system such as ODBMS. In this case, it is considered that data is represented in a structured way, and there is no ambiguity in data.In order to retrieve the desired data the user present a set of criteria by a query. Then the Database Management System (DBMS), software for managing databases, selects the demanded data from the database. The retrieved data may be stored in a file, printed, or viewed on the screen.A query language, such as Structured Query Language (SQL), is used to prepare the queries. SQL is an American National Standards Institute (ANSI) standardized query language developed specifically to write database queries. Each DBMS may have its own language, but most relational.Reports and queries are the two primary forms of the retrieved data from a database. There are some overlaps between them, but queries generally select a relatively small portion of the database, while reports show larger amounts of data. Queries also present the data in a standard format and usually display it on the monitor; whereas reports allow formatting of the output however you like and is normally printed.Reports are designed using a report generator built into the DBMS.

Data transmission

Data transmission, digital transmission or digital communications is the physical transfer of data (a digital bit stream or a digitized analog signal) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal.
While analog transmission is the transfer of a continuously varying analog signal over an analog channel, digital communications is the transfer of discrete messages over a digital or an analog channel. The messages are either represented by a sequence of pulses by means of a line code (baseband transmission), or by a limited set of continuously varying wave forms (passband transmission), using a digital modulation method. The passband modulation and corresponding demodulation (also known as detection) is carried out by modem equipment. According to the most common definition of digital signal, both baseband and passband signals representing bit-streams are considered as digital transmission, while an alternative definition only considers the baseband signal as digital, and passband transmission of digital data as a form of digital-to-analog conversion.
Data transmitted may be digital messages originating from a data source, for example a computer or a keyboard. It may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream for example using pulse-code modulation (PCM) or more advanced source coding (analog-to-digital conversion and data compression) schemes. This source coding and decoding is carried out by codec equipment.
Data manipulation

A data manipulation language (DML) is a family of syntax elements similar to a computer programming language used for selecting, inserting, deleting and updating data in a database. Performing read-only queries of data is sometimes also considered a component of DML.A popular data manipulation language is that of Structured Query Language (SQL), which is used to retrieve and manipulate data in a relational database.Other forms of DML are those used by IMS/DLI, CODASYL databases, such as IDMS and others.Data manipulation language comprises the SQL data change statements, which modify stored data but not the schema or database objects. Manipulation of persistent database objects, e.g., tables or stored procedures, via the SQL schema statements, rather than the data stored within them, is considered to be part of a separate data definition language. In SQL these two categories are similar in their detailed syntax, data types, expressions etc., but distinct in their overall function.Data manipulation languages tend to have many different flavors and capabilities between database vendors. There have been a number of standards established for SQL by ANSI,[1] but vendors still provide their own extensions to the standard while not implementing the entire standard.
Data manipulation languages are divided into two types, procedural programming and declarative programming.Data manipulation languages were initially only used within computer programs, but with the advent of SQL have come to be used interactively by database administrators.
