hi,

a perfect network would be right as you search something it would work in a snap, super protected, no hackers, would have maintenance every week, everyone one would share anything and everything as long as its safe, no viruses or over 18 stuff.communication would be like hangouts, and a network administrators would check what is happening and check if everything is safe.

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?
