Comparison between Input & Output Devices



What is Input and Output Devices?

Input and output devices allow the computer system to interact with the outside world by moving data into and out of the system. Input and Output are the devices which help a computer to process its data and give it new information. Inputs and outs put devices are very important for a computer system because the whole work of the computer is controlled by the input and output devices. Let's describe them one by one.


Inputs Devices:

An input device is used to bring data into the system. This kinds of devices help us to connect to the computer some input devices are:
  • Keyboard
  • Mouse
  • Microphone
  • Bar code reader
  • Graphics tablet
  • MIDI keyboard
  • Punch card reader
  • Scanner
 









Output Devices:
An output device is used to send data out of the system. Some output devices are:
  • Monitor
  • Printer
  • Speaker
A network interface acts as both input and output. Data flows from the network into the computer, and out of the computer into the network.










Relation Between Inputs and Outputs Devices:


As an example, the key switch inputs on a keyboard that are labeled A, M, I, T could cause a screen output device to emit light that shows the word AMIT  in a document. Or they could move an imagined avatar through a 3D world displayed by light from the TV screen. Or they could cause the motors on a drone to change speed by a radio-controlled motor so the drone moves through the real world. We can give more example of it Like we control the drone by the remote control device so is also an example of inputs and outputs devices.


Input Vs Output:

The difference between input and output devices is simple. As the names suggest, input devices allow data to be pulled into a computer, and output devices share data with the outside world. Whether a computer is a smartphone, desktop, laptop or mainframe, it typically has both input and output devices.Input devices are necessary for a computer to receive commands from its users and data to process. Output devices are necessary for a computer to share their results and prompt users for more information and commands.

                                    What is Software?                                      In 21 st Century which is also called the century of Globalization and the century of Computer Technology. From the very basic of Computer, it has only two major parts one is Software and another is Hardware. If we look at the Human body structure, we can find that our brain is Controlling our whole body, similarly, software is the things which control the whole computer system. It’s controlled the computer system as a director, instructor or so on. On the other hand, Hardware is the things which make the structure of a Computer. According to IEEE software is a “ Collection of Computer programs, rules, and associated documentation and data.”   In General word, Software is some sort of written programs which can make computer understandable of its work. What’s the Classification of Software?     There are two Categories of Software, the first o

  Definition - What does   Computer Ethics   mean? Computer ethics deals with the procedures, values and practices that govern the process of consuming computing technology and its related disciplines without damaging or violating the moral values and beliefs of any individual, organization or entity. Computer ethics is a concept in ethics that addresses the ethical issues and constraints that arise from the use of computers, and how they can be mitigated or prevented. Computer ethics primarily enforces the ethical implementation and use of computing resources. It includes methods and procedures to avoid infringing copyrights, trademarks and the unauthorized distribution of digital content. Computer ethics also entails the behavior and approach of a human operator, workplace ethics and compliance with the ethical standards that surround computer use.   The  Ten Commandments of computer ethics  have been defined by the  Computer Ethics Institute:   1) Thou shalt not use

  Before talking about the programing language Generation let’s talk what computer program is? •Program is a collection of suitably ordered instructions, • the instructions that a program needs are written (or coded) in some programming language, • And it is executable by a computer to perform a specific task. The logical content of a program is based on one or more algorithms. The logical content of a program is based on one or more algorithms. Algorithm . So, What about the Algorithm? • Algorithm is a logical part of a computer program which specifies the solution of a well-defined task, • Actually, Algorithm is a self-contained step-by-step set of operations.   What is Programming Language?    A Programming language is a formal language which specifies a set of instructions and the rules of their application. By the correct use and combination of the instructions we can create our programs. A lot of programming languages have been developed since
