What is computing?
The concept computation comes from the Latin computation; this refers to the computation, as account. Computing is the science in charge of studying systems, more precisely computers, that automatically manage information.
Within computer science, different areas of study can be distinguished:
- Data structure and algorithms. An important study in computing is that of data structure and algorithms. For this, these last two are analyzed to solve the precise problems. Mathematical analysis is elementary In this area.
- Operating systems. Operating systems are also considered one of the most important areas. They are continually created and updated to improve operation, improving failures and adapting them to new market needs.
- Computer architecture. Regarding the area of computer architecture, new computers are created, faster and with better capabilities. The focus is usually on certain components, such as memories, CPUs, and peripherals (input and output).
- Programming languages. Another elementary area in the study of computing is that of programming languages. The objective is to create new programming languages, which are more efficient and faster, with superior functionalities and capabilities.
History of computing
Although the use of computers and their study has been widespread in recent decades, computer science has a long history. Already from ancient civilizations, such as the Romans and Greeks, used mechanical instruments to count.
However, the first computer was created during the 19th century. This machine arose intending to prepare mathematical tables. A few years later, the English government would use them to do accounts. In the late 1940s, a computer called Mark I was created at Harvard University. Attempts would continue across the United States with government support.
When the number of designs began to increase, they began to be classified by their characteristics in generations:
- First-generation. Throughout the 1950s, they were characterized by their programming being by machine language and designed with vacuum tubes. They also occupied entire rooms due to their large size and were too expensive. As in the second generation, the information that entered the machine was through punched cards.
- Second generation. This generation boarded the sixties. During this generation, computers were able to process more data and were slightly smaller. It was during these years that communications between machines began to emerge. At the same time, the first personal computers arose, anyway, they were so complex to use that it was necessary to know the programming.
- Third generation. It was during the third generation that production began to be serial. Computers could be managed through operating systems. Many of the techniques used in those years became standards that are still used to this day.
- Fourth generation. The fourth generation is recognized for the appearance of microchips. The circuits not only began to be much smaller and faster, but in turn, they were much cheaper. That is why production increased significantly, and many more people had access to them. This generation is also known as the Computing Revolution.
The impacts on everyday life
Currently, computer technologies have allowed the reworking of traditional concepts of activities, in this way the technologies began to transform people’s lives profoundly and in all their activities:
- Traditional mail was replaced by sending and receiving email.
- The art of the draftsman underwent modification and became the production of digital drawings.
- The audio edition is fully digitized.
- The printing of books was transformed into the publication and digital edition on computer media that are simultaneously marketed via the Internet, among many other processes.
That is, the scope of computing is boundless, the modification in the processes of activities has already occurred and continues its advance strangely, constantly transforming our lives and creating new personal requirements that require us to be aware of these new resources, both to know and know about their use and to know how to take advantage of them in pursuit of better personal and social well-being.
