How did DDE devices have made our daily life easier?

The answer to this question is given below in the explanation section.

Explanation:

DDE (direct data entry) devices are the devices that read data from a source and transfer it directly into the computer. Unlike, other input devices which require physical interaction which requires you to move physically or to do something for an output or feeding data into a computer.  

The DDE devices require no hard work while taking input into the computer as compared to other input devices. These DDE devices made our life very easy. Because these devices take input accurately and there are no chances of human error.

The example of DDE devices are magnetic stripe reader, chip reader, Pin pads, optical mark reader, and barcode reader, etc.

These devices have brought great advantages to human life. Because by using these data entry devices, information can be put into very quickly, more accurate than typing and information of the whole page transferred .very quickly and accurately into the system. These devices are also more secure and can hold lots of data, and the data is protected with the PIN (personal identification number). These are also used in ATM machines, handheld, and entry doors.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
