Lightning Stirikes can cause momentary losses of power which can cause data loss. Lightning can also cause more serious damage with the complete loss of hardware, software and data.
Floods can lead to water damage to hardware, software and data, loss of power or communication lines.
Threats From Faulty Hardware or Software
Computers can go wrong at anytime, its easy to replace hardware but it's not as easy to replace programs or data.
Faulty Hardware- computer is fairly reliable but can and does break down. The main problem would be caused by the hard drive becoming damaged, rendering the data and the programs unusuable.
Faulty Software- software, especially bespoke software, and sometimes packaged software, can contain errors (or bugs as they are called) and these cause damage or loss of data.
