The Chair To Keyboard Interface, aka the CKI, is the most essential component in the setup and use of your computer system. A corrupt, or improperly tuned, CKI can cause disasters. Fortunately, a CKI fault (aka PEBCAK) will not cause deadly results, as you might get with a similar fault while driving your car, for instance.
Computer systems are designed to be fault tolerant, in this regard. That does not, however, mean that you should freely operate your computer while heavily under the influence of various factors:
- Cats and Coffee.
- Drugs - legal and illegal.
Your computer security, in the end, depends upon you. All the security programs on your computer are challenged, and possibly useless, when you go surfing to websites which you know you don't belong on, or you go out in public, unaware of your surroundings.
Common sense = CKI Optimisation = Protection.
