A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. Computers that are freely programmable and can, at least in principle, process any data / information are called universal. Current computers are not only information processing machines, but devices that facilitate communication between two or more users, such as numbers, text, images, sound or video, or all at once (multimedia).

The oldest known mechanism that appears to function as a calculating machine is considered to be “clock” of Antikythira, dating to the year 87 BC and apparently used to calculate the movements of planets. The technology was the basis of this mechanism is not known.

In the first half of the twentieth century, the scientific community computing needs were met by analog computers, highly specialized and increasingly sophisticated. Improvement of digital electronics (owed by Claude Shannon in 1930) led to the abandonment of analog computers for the digital (numeric), which shape the issues in numbers (bits) instead of electrical or mechanical signals.

In the 1960s lamps (electronic tubes) were replaced by transistors, more efficient, smaller, cheaper and more reliable, leading to miniaturization and cheaper computers. Since the 1970s, adoption of integrated circuits further lowered the price and size of computers, allowing among others the emergence of personal computers today.

Nowadays, everyone has PC games ( personal computer games). It is a game played on a personal computer. Computer games constitute a category of software that is design for fun. There are several types of PC games, such as action games, strategy, arcade, simulator, card games, adventure etc..

Although, computer games are made for fun, there are several disadvantages when someone starts to play something.

First of all, people do not know when to stop. This refers to the fact that they play sometimes to much and here comes several problems. One the one hand, staying too much in front of a computer affects our health (especially our eyes). One the other hand, it causes addiction.

Second of all, if we play to much it won’t affect only our body, but also our computer. Our computer can get viruses (if we play online, or even if we bought the games online), or it can get overloaded. Or maybe if we want to play a game our computer needs to be uploaded and it cost a lot of money ( and thinking that it is only for a game, maybe it is not worth it).

And a other disadvantage is the fact that some PC games present too much violence. That is why the PC games have long been a source of controversy. Because there are minors that are playing those games and it affects them, there character, their way of being.

All in all, playing computer games involves a lot of consequences which that we can class as disadvantages. And that is why if we start playing computer games we should control ourselvels.
