I believe you may mean a "PROVEN" truth. An example would be: 2+2=4 - Water is wet. The sun rises in the morning. These are over-simplified examples but are simple examples of truths that are, in and of, themselves "proven" and cannot be doubted or argued.

What size external hard drive is needed to hold 150000 songs?

Depends entirly on bitrate and encoding.

Taking averages say 160kbps mp3 file of about 4:30 minutes.

(150000 * (((4*60 + 30)*160)/8/1024/1024))/1024 = 772.476 GB

{[no songs] * [time in seconds]*[bits per second] / 8 / 1024 / 1024 / 1024} gives an answer in gigabytes

so at that bitrate and encoding a 1 terabyte hdd would do.

Why a regional bank might decide to but six server computers instead of one supercomputer?

Supercomputers are large processing clusters, dedicated to solving various problems through constant computation; Supercomputers are essentially a single application that does complex equations over large datasets.

Servers are much cheaper and much more adaptable than supercomputers. They can run a variety of operating systems and software at competitive mainstream prices. Servers can used redundantly, with servers supporting each other should one fail. Hardware can also be bought in the mainstream market, allowing easier upgrades and migrations.

Disaster prevention is a proactive strategy focused on controls to ensure that a disaster does not happen. Disaster recovery focuses on controls in place in case a disaster does happen.

This is thus a reactive strategy and works more in case of unpredictable disasters, such as natural disasters which cannot be prevented by man.
