Mobile computing refers to the ability to use technology without restriction, facilitated by mobile computer devices. Since the early nineties, many types of mobile computers were introduced, including handheld computer, smartphone, tablet and Mobile Internet Device (MID).
The mobility factor is a standard and a benchmark in the computer industry for performance evaluation in terms of mobility in the field of various types of mobile computers. For mobile use of computers rely primarily three aspects: battery life, weight and robustness.
To determine the simplified mobility factor the battery life of a computer is taken into account in relation to its weight. The expanded mobility factor is obtained from the multiplication of the factor simplified for the compressive strength expressed in kgf. On the basis of these parameters, it is possible to compare different models of the same class of mobile computers in an absolutely transparent manner.
With the mobility factor, the individual values of excellence fade into the background, because you can get very good marks only by virtue of a balance of the three most important performance factors for mobility (autonomy, weight and robustness).
A personal computer is meant to be used directly by an end user, without the intervention of a qualified computer technician. This is in contrast to servers that allow large and expensive mainframe systems to be used by many users, usually at the same time. Or with the computer systems for the processing of large databases, requiring the efficient work of a team of technicians employed full time.
Variants
Personal computer should be, in the original meaning of the term, any computer that has been designed for use single user, that is, by only one person at a time (as opposed for example to mainframes, with which whole groups of people simultaneously access through remote terminals).

Nowadays, the term personal computer has been customary to indicate a specific band in the IT market, that of the computer for private use, home, office or for small business. In some cases, personal computer or PC is used with a meaning even more specific, but restricted to the range of IBM compatible machines.
In fact, in more technical jargon, contrasts with PC to Mac meaning, in the first case, a computer (IBM compatible) with Windows operating system and in the second case, an Apple computer on which then turns the Mac operating system.
The progressive flattening technology, which depends on performance characteristics of the personal computer towards the server and mini computers, often make it difficult placement of a computer within the canonical classifications.
