Magnetic tapes

Explanation:

The CERN research laboratory mostly store their data in Magnetic tapes which are their main storage medium. The reason behind selecting magnetic tape is that it can store huge volumes of data. It is relatively less expensive and durable for long-term storage. With the passage of time, the CERN has expanded its data centres and their centres are linked with each other through high speed fibre optic networking

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?
