Definition Of Computing
Computing is the science in charge of studying the systems, more precisely computers , that automatically manage information.
Important Areas Of Computation
Data structure and Algorithms: An important study in computing is that of data structure and algorithms . For this, the last two are analyzed in order to solve the precise problems. In this area the mathematical analysis is elementary.
Operating systems: Operating systems are also considered one of the most important areas. They are created and updated continuously to improve the functioning, improving failures and adapting them to the new needs of the market.
Computer Architecture: With regard to 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 functionalities and overcoming capabilities.
Classification Of Computers
First Generation: Throughout the fifties, they were characterized by the fact that their programming was by means of machine language and designed with vacuum tubes. They also occupied entire rooms because of their large size and were too expensive. As in the second generation, the information that entered the machine was through punch cards.
Second Generation: This generation has barked the sixties. During this generation, computers could process more data and were a bit smaller. It was during these years that communications between machines began to emerge. In turn, the first personal computers emerged, however they were very complex to use, it was necessary to know the programming.
Third Generation: It was during the third generation when production began to be serial. Computers could be managed through operating systems. Many of the techniques used in those years became standards that are used today.
Fourth Generation: The fourth generation is recognized by the appearance of microchips. This meant a milestone in computer science. The circuits not only began to be much smaller and faster, but they were much cheaper. That is why the production increased significantly and many more people had access to them. This generation is also known as the Computer Revolution.
Use Of Computation In Everyday Life
Traditional mail was replaced by sending and receiving email.
The artist’s art underwent modification and became the production of digital drawings.
The audio edition is fully digitized.
The printing of books became the publication and digital edition in computer media that
are both marketed via the Internet , among many other processes.
Brief Explanation Of CPU
CPU is an abbreviation of Central Processing Unit . The CPU is a basic component of the personal computer or computer that processes data and performs mathematical-computer calculations.
The CPU provides the programming capacity , and together with the memory and the input / output devices, it is one of the computational components that we find present in the entire history of computers. The microprocessors of a chip have been replacing the CPUs until they reach the current days when usually when referring to this term they talk about the microprocessors .
At the beginning, when the CPU began to be talked about in the 60s, this unit had a large size, but over the years, technological development led to the fact that computers nowadays have more reliable processing, technical security and efficiency . It is also necessary to highlight that in the beginning, because of their price, size and the possibilities of use, the CPUs were only used in the field of universities.
For every 18 months the efficiency and power capacity of the CPUs is doubled due to technological innovations . There are two typical components that a CPU needs: the arithmetic unit or called logic, and the control unit which only extracts the instruction from memory , decrypts it and executes it.
The CPU is based on program operations specially designed for computer transmission and use , whose basic steps are to collect information, decode it in smaller parts in which it can interpret that coding, and carry out instructions, which it will finally execute, moment in which different parts of the CPU that act together are involved.
