Although latest computer models tend to be smaller and smaller and a lot easier to handle, problems can appear due to their software, namely computer programs, or hardware, namely computer parts. The accent nowadays is more and more on electronic devices that are self-sufficient or need little maintaining, but last for short periods of time. Among these types of devices computers are the ones having the smallest shelf-life, due to the numerous improvements that appear on the market every year.

The need for continuous improvement in this market is due to the importance of computers in our lives. In order to adapt to all the various needs computer specialists are doing research all the time, not only referring to programming but also to computers’ configuration. It is quite difficult to accommodate all the needs from those of the children playing games at high resolution to scientist needing computers capable of running complicated algorithms in a limited amount of time. Finding the universal computer is an ambition of every manufacturer and why not of every business owner. Not long ago people started having dreams about computers working in their place and leaving them time for leisure.

Self-sufficiency of electronic devices is also related to their operation which tends to be more and more easy in order to eliminate human errors. But humans will always be unpredictable and no IT programmer can take in account every kind of computer related programs that can appear during its functioning as much as he will try. But every day very complicated computer algorithms are designed in order to cover as much as possible the entire spectrum of problems cannot be foreseen. Also these complicated algorithms that are designed to help us, will impeach a non-IT support specialist to repair a computer.
