Difference Between Input Device and Output Device

In today’s tech world, no one does not-not know the difference between input and output devices. However, a deeper meaning exists beneath the basic definition of the terms input and output devices. The terms input and output, as the name suggests, refer to devices that can give or accept information from a median device.

Input Device vs Output Device

The main difference between an input device and an output device is that while the input device talks about a component that accepts incoming or receiving data, the output device, on the other hand, signifies the opposite of it. Both forms of the data sent or received have to be translated to a binary code that can be read and interpreted by the device in question.

Input device refers to any device that acquires and receives external data into a computer or any other electronic device. This data is then decoded into a pattern of binary codes that are read by the device and interpreted. The data that is obtained from the user is later filed away to be interpreted or processed so that the result can be displayed/executed.

Output device refers to any device that showcases the obtained information to its users. It can be considered as the mirror image of an input device. The processed data that is initially received by the device from a processor are analyzed, interpreted, and sent back to the user in a way that can be understood.

What is an Input Device?

Any device that acquires and receives external data into a computer or any other electronic device is termed as an input device.

The name itself suggests what input devices refer to. They take in the data provided to the device and observe/analyze the received input. 

This data is then decoded into a pattern of binary codes that are read by the device and interpreted. The data that is obtained from the user is later filed away to be interpreted or processed so that the result can be displayed/executed.

The information sent is regulated by the user in the input device; therefore, any raw input that is fed into the device can be monitored by the user in accordance with his or her preference.

Input device decodes the data provided by the user to data understood by the machine. This is important in order for the information to be run through and processed in a way that can be useful.

Devices used in the input play a vital role in helping computers in accepting external data into the system. 

Devices used for input are made to be connected to a computer or any other device and send information to the afore-mentioned device.

Examples of devices used for input include a microphone, the keypad,  a joystick, image scanners, and similar devices.

What is an Output Device?

Any device that showcases the obtained information to its users. It can be called a mirror image of the input device owing to the functions performed is termed as an output device.

The term output device by itself suggests the use and function it is meant for. Devices used for output are connected to a computer, and information is sent via that channel.

The received data is controlled by the processor in the output device.

The processed data that is initially received by the device from a processor are analyzed, interpreted, and sent back to the user in a way that can be understood.

It helps in showcasing the processed content to the user.

They are tasked with the responsibility of changing, altering, and eventually showcasing the analyzed output into data that can be viewed by the user.

This process is mainly used in helping or assisting the device in displaying internal data.

Output devices are designed in a much lesser complex way.

The processes in an output device belong to a component that is expected to convert the information received in a binary code or digitized signals into such a manner that can be seen, heard, and understood by the user.

Known as the opposite to devices used for input, output devices can also be utilized to send information from one computer system to another.

Monitors and printers can be considered as examples of devices used in showing output.

Main Differences Between Input Device and Output Device

  1. The computer is sent information that has to be processed in the device meant for input. Whereas an output device is connected to a computer to display the information received by it.
  2. The information sent is regulated by the user in the input device. The received data is controlled by the processor in the output device.
  3. Input device decodes the data provided by the user to data understood by the machine. Devices used in output devices change the internal data to be user intelligible. 
  4. The purpose of input and output devices is to help devices in accepting external data and displaying the internal data, respectively.
  5. Input devices are generally more complex and output less complex.

Conclusion

These are computer components that are vital to its working and functioning. Any device requires data that needs to be entered, and this data to be processed, analyzed, interpreted for further action to be taken.

The next steps include the interpreted data in binary code or any other computer language to be displayed the right way for the user to understand.

The purpose of these devices is to help devices in accepting external data and displaying the internal data. Input devices are generally more complex and output less complex.

Input and output devices play a role in sending information and receiving it, respectively.
