Some file systems allow disk storage to be allocated at different levels of granularity. for instance, a file system could allocate 8 kb of disk space as a single 8-kb block or as sixteen 512-byte blocks. how could we take advantage of this flexibility to improve performance? what modifications would have to be made to the free-space management scheme in order to support this feature?

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?
