Easy-to-understand lightning and surge protection

What is the difference between a direct and an indirect lightning strike and how do they affect buildings? What are the causes for surges and how do they threaten electronic systems? What has to be observed when installing surge protective devices and how can installation errors be avoided? Are there special requirements for IT systems?
