Communication

Image
  Communication Communication is simply the act of transferring information from one place, person or group to another. Every communication involves (at least) one sender, a message and a recipient. This may sound simple, but communication is actually a very complex subject. The transmission of the message from sender to recipient can be affected by a huge range of things. Categories of Communication Spoken or Verbal Communication -  which includes face-to-face, telephone, radio or television and other media.  Non-Verbal Communication -  covering body language, gestures, how we dress or act, where we stand, and even our scent. There are many subtle ways that we communicate (perhaps even unintentionally) with others.  Written Communication -  which includes letters, e-mails, social media, books, magazines, the Internet and other media.   Visualizations -  graphs and charts, maps, logos and other visualizations can all ...

Electronic Communication

 Electronic Communication Electronic communication can be defined as, the communication which uses electronic     media to transmit the information or message using computers, e-mail, telephone, video    calling, FAX machine, etc.  This type of communication can be developed by sharing data like images, graphics, sound, pictures, maps, software, and many things.  Because of this communication, there is a lot of changes have occurred in work areas, society, etc.  Thus, people can simply access global communication with no physical movement. Types of Electronic Communication  Electronic communication can be classified into different types like messaging, voice call, e-mail, social media, etc.  We know that e-communication has changed due to the way public interact and communicate with each other for different purposes like personal or business.  By using this, it is very simple to communicate with the world     ...

Logic Gates

Image
  Logic Gates Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a  certain logic . Based on this, logic gates are named as AND gate, OR gate, NOT gate etc. AND Gate A circuit which performs an AND operation is shown in figure. It has n input (n >= 2) and one output. Y = A.B Logic diagram Truth Table OR Gate A circuit which performs an OR operation is shown in figure. It has n input (n >= 2) and one output. Y = A + B Logic diagram Truth Table NOT Gate NOT gate is also known as  Inverter . It has one input A and one output Y. Logic diagram Truth Table NAND Gate A NOT-AND operation is known as NAND operation. It has n input (n >= 2) and one output. Logic diagram Truth Table NOR Gate A NOT-OR operation is known as NOR operation. It has n input (n >= 2) and one output. Logic diagram Truth Table XOR Gate XOR ...

Number Systems in Computer

            Number Systems in Computer The number system is something we use every day to complete our tasks and routine activities. For this, we have a system in place with unique symbols and specific values. This system becomes what we call a number system helping us calculate everything. The basic features of a number system are – unique symbols, consistency, comparable value results and are easy to reproduce. The Decimal system remains the most basic system used by humans with a base power of 10 but the same things can’t go for machines as well.  Machines interpret numbers differently from humans thus require a different system altogether. Whenever we type something on a device, those letters convert into certain numbers which only the computer can understand. A positional number system is what a device needs where there are digits and different values making up an entire number. Each digit has its own unique position and a symbol. Each digit’s val...
