Computer science provides solutions in multiple areas.
The term computer science comes from the French informatique , implemented by engineer Philippe Dreyfus in the early 1960s. The word is, in turn, an acronym of information and automatique .
In this way, computing refers to the automatic processing of information using electronic devices and computer systems . Computer systems must have the capacity to fulfill three basic tasks: input (capture of information), processing and output (transmission of results). The set of these three tasks is known as an algorithm .
Uses of computing
Computing brings together many of the techniques that man has developed with the aim of enhancing his thinking, memory and communication capabilities. Its area of application has no limits: computing is used in business management , information storage , process control , communications , transportation , medicine and many other sectors.
Computer science also covers the main foundations of computer science , such as programming for software development, computer and hardware architecture, networks such as the Internet , and artificial intelligence . It is even applied to various topics in electronics .
History and evolution
The first programmable and fully automatic machine in history is considered to be the Z3 computer, designed by the German scientist Konrad Zuse in 1941 . This machine weighed 1000 kilograms and took three seconds to perform multiplication or division. Addition or subtraction operations, on the other hand, took 0.7 seconds.
Hardware is an important part of computing.
The evolution of computing in recent decades is not as interesting as what its users have gone through, since many of them went from a state of lack of interest to one of absolute dependence on technology . Needless to say, there are nuances in this story: using a computer or a mobile phone does not make us experts, but it is more than keeping us aside from this phenomenon simply due to the lack of will to understand its potential.
Computing was a true revolution that began in the late 1970s with home computers but gained more strength during the 1980s and exploded in the 1990s. We are, therefore, facing a process that took around two decades to flourish. complete, although its level of massification increased drastically in the middle of the 21st century when the three crucial elements of computing were finally combined: video games, the Internet and mobile phones . Yes, portable devices played a fundamental role in the difficult task of convincing the most skeptical to break down their barriers and start enjoying computing.
The importance of computing
Any use we make of a program to automate our activities can be included in the computing category, no matter what device it is on. Thanks to the introduction of mobile phones and, later, tablets, many people dared to take their first steps through email boxes, instant messaging and writing documents in digital format, and later moved on to computers. , particularly laptops, and finally take advantage of the series of features that have been around for years.
In the workplace, computer skills can be key to accessing certain offers, although this is incorrectly represented by the requirement for different academic degrees. This requirement is very common and thanks to it there are thousands of training institutions that offer official certification after the courses. Computer science is the basis of almost all the tasks carried out in most companies, because it allows us to organize and control them in a more orderly and efficient way than pencil and paper.
