Question

The largest computational problems, such as those encountered in modeling three-dimensional physical phenomena, can be solved by a single compute as long as it has enough computing resources. a. True b. False Answer_____ People routinely download megabytes or gigabytes of data via the internet and store gigabytes of data on handheld devices, terabytes on desktop computer, and petabytes to Exabyte in corporate and government data centers. a. True b. False Answer ____ Reducing the size of stored or transmitted data can improve performance whenever there's a dearth of processing power. a. True b. False Answer ____ Zip files and archives are examples of lossless compression. a. True b. False Answer ___ Lossless compression ratios higher than 50:1 are difficult or impossible to achieve with audio and video data. a. True b. False

Explanation / Answer

24) True

If you consider a supercomputer or quantum computers then these systems have enough computing power as well as resources to compute such problems.

25) True

Computer scientists have not yet achieved a technology which could accomodate terabytes of data on handheld devices. Although IBM is working over their '12 atom magnetic memory' technology that would enable us to do the same.

26) False

It can possibly improve performance in a situation where there is plenty of inexpensive processing power but less plentifull data storage.

27) True

Yes they are lossless as when the ZIP files are extracted, they are exactly of the same size as they were originally. This proves no data is lost when ZIP files are compressed and extracted.

28) True

Lossless compression ratios higher than 3:1 are difficult or impossible to achieve with audio and video data whereas lossy compressions of audio and video can achieve compression ratios upto 50:1.
