 WRITTEN COMMUNICATION –   - Written communication is sending written messages, written orders, and written instructions over circulars, reports, letters, emails, telegrams, bulletins, manuals, etc.  -This method communication is very formal and less flexible. - It is mainly used when the information is lengthy and contains complex terms which are difficult to explain verbally.  - These written documents can also be used in the future as legal evidence, and hence they should be appropriately preserved.  Advantages of Written Communication: 1. Easy to preserve: The documents of written communication are easy to preserve. Oral and non-verbal communication cannot be preserved. If it is needed, important information can be collected from the preserved documents.  2. Easy presentation of complex matter: Written communication is the best way to represent any complex matter easily and attractively.  3. Permanent record:  The documents of written...

 INTRODUCTION TO COMMUNICATION – -Communication is as old as human civilization. The common need for protection led to group life.  -As group life developed, forms of communication also developed. Communication was in the forms of codes, indications, signals and expressions. - Gradually with the increase in population, division of labour, exchange economy, etc., necessitated the development of language. - In the present-day world, communication is vital need of every Step in any industrial or commercial activity.  -The term communication has been derived from the Latin word, ‘communis’, which means common.  -Literally, communication means, to tell, show, spread the information and inform. The term communication is used to signify the process of transferring ideas or receiving it by any meanssuch as word of mouth, telephone, telegram, letter, message, etc. - Thus, communication stands for sharing of information, imparting or conveying ideas and knowledge.  MEANI...

BIG DATA  - Big data refers to the large and complex datasets that are beyond the capability of traditional data processing applications to capture, store, manage, and analyze within a reasonable timeframe. - The concept of big data revolves around the "three Vs":   1. Volume 2. Velocity 3.Variety  i. Volume:   This refers to the sheer size of the data being generated. Big data typically involves datasets that are too large to be handled by conventional databases or tools. The data can range from terabytes to petabytes and even exabytes.  ii. Velocity:  Velocity pertains to the speed at which data is generated and needs to be processed. With the advent of the Internet of Things (IoT) and real-time data sources, data is generated rapidly and continuously. Big data systems must be capable of handling and analyzing data in near-real-time or real-time.  iii. Variety:  Big data encompasses diverse types of data, including structured, semi-stru...

" HUMAN TO MACHINE INTERFACE "- Human-to-machine interface (HMI), also known as human-machine interface, refers to the means by which humans interact and communicate with machines, devices, or computer systems.   - It involves the exchange of information, commands, and feedback between humans and machines, enabling users to control and interact with technology effectively.  - HMI can take various forms depending on the nature of the machine or system being used.   Here are some common types of human-to-machine interfaces:  1. Graphical User Interface (GUI): -GUIs use visual elements such as icons, menus, buttons, and graphical representations to enable user interaction. - They provide a visual and intuitive way for users to navigate through software applications or operating systems. - Examples include desktop interfaces, smartphone interfaces, and touchscreens.  2. Command Line Interface (CLI): -CLI interfaces require users to enter text-based com...

DATA: MEANING  - Data refers to raw, unprocessed facts, observations, measurements, or statistics that have been collected or generated. It can be in various forms, such as numbers, text, images, audio, video, or any other type of information that can be digitally represented.  - Data is often used as the foundation for generating insights, making informed decisions, and solving problems. - Data can be categorized into two main types:   1. Quantitative Data :   Quantitative data is expressed in numerical form and can be measured and analysed using mathematical and statistical methods. Examples of quantitative data include sales figures, temperature readings, survey responses on a rating scale, or the number of website visitors.    2. Qualitative Data:  Qualitative data is non-numerical and describes qualities or characteristics. It is typically gathered through observations, interviews, focus groups, or open-ended survey questions. Examples of ...

  TECHNOLOGY: MEANING - Technology refers to the practical application of scientific knowledge, tools, methods, and systems to create, modify, or solve problems in order to improve human life and the world around us.  - It encompasses a wide range of processes, techniques, artefacts, and devices that are designed to fulfil specific purposes and achieve desired outcomes.  - Technology can be categorized into various types, including: 1. Information and Communication Technology (ICT): This includes hardware, software, and systems used for processing, storing, retrieving, transmitting, and presenting information. Examples include computers, smartphones, the internet, software applications, and telecommunication networks.  2. Biotechnology: This field involves the application of biological knowledge and processes to develop products and technologies that enhance human health, agriculture, and the environment. Examples include genetic engineering, pharmaceuticals...
