When we use a computer, it works because it is made up of a computer element seriesstarting with what is The operating system. In order to understand how this OS works, it is first necessary to know what a computer system consists of and how it is constituted.
It’s important to put attention on the computer system It has become today a very important part for the human being, taking into account that currently everything or almost everything It is controlled by a computer. Therefore, it is impossible to think of a society apart from a computer.
According to this, here we are going to teach you what it is?, what is it for? and how it works? The computer system of a computer and what are each of its elements.
What is a computer system and what is it for?
The computer system or also known by its acronym YES, is a system that takes care of store and process information that is generated on a computer. To do this, it has a set of interrelated parts as are he hardware, software and the user. All of them are necessary for the equipment to be functional for the human being.
Bearing in mind that it is the user who requires the information processed and, furthermore, he is the one who has the absolute control about everything that happens or is carried out in the system. Therefore, the YES has the function of collect all data process them and then transmit all the information once been 100% processed.
What are all the parts that make up a computer system?
As we have already mentioned, the SI is constituted by a series of elements or parts that compose it and that they are completely necessary for its execution. In this way, he is in charge of be able to manage hardware resources and in turn power control all apps so that the user can get the best results.
That is why here we are going to explain each of its parts, such as the hardware, software and firmware.
Software
This component of YES It is made up of a set of programs that have been created to carry out a determined action within a system. These actions can be performed by the same computer companies or simply be carried out by the users.
In other words, they are the programs that are responsible for giving instructions to the computer so that this can communicate and carry out a series of corresponding activities. In this case the software cannot be touched.
It is also important to mention that this component is the logical part of a computer system, since it is who allows the equipment to function. Therefore, software is not only made up of the programsbut also for user information and all data that is processedAll of this is intangible, that is to say, that none of this we can see or touch.
Hardware
Unlike softwareWhen we refer to hardware we are simply talking about everything that we can see and touch on a computer. So this refers to the physical parts of the PCas they are chips, printers, cables, monitor, boards, integrated circuits, hard driveamong many other elements.
Therefore, the computer is a piece of equipment that is in charge of constantly processing information in a very short time. where it requires so much software instructions which are made by one of the devices connected to the computer, then the hardware. In general, these components fulfill the following functions: input, processing, storage and output of data.
firmware
It is present in any team that is made up of both a hardware and software. He refers to a series of instructions in a computer program which is stored in flash memory or ROM. These instructions deal with fix a logic at the time of exert control of the circuits of some device.
That is how firmware is a piece of hardware, because it is integrated into the electronics. However, it is also considered a part of the softwaresince it is developed in a computer programming language. In the case of firmwares, they must fulfill three specific functions for their good performance.
The first one consists of give the system the routines of its operation and the answers regarding the requests that it constantly receives and which must be carried out to meet the needs and demands of users. It is also in charge of create an interface so that the fast system setup and finally control and manage system boot on the computer.
What are the different types of computer systems that exist?
Today there are different types of computer systems, where each one of them exerts a fundamental action for what is the operation of an electronic machine. Taking into account that without them almost no activity could be carried out.
Because of all the functions they perform, it is important that there is a classification according to the type and its function. Therefore, here we are going to teach you How are the SIs that currently exist classified:
- Decision support system: These systems are also known as decision support or Decision Support System or by its acronym DSS.
It has been designed to carry out what are the processes of decision makingand it can be used by management in order to solve problems and be able to choose the most viable option And power predict what the future scenarios are and so be prepared for any eventuality:
- Business collaboration system: Also known as Enterprise resource planning or by its acronym ERPare a system of business collaboration used by most of the companies around the world, since it gives the facility to the different companies of to be able to manage all the information that circulates within the company.
- executive information system: This system is capable of providing users with immediate access to all critical information that is handled within the company, whether external or internal sources. All this information is usually presented in a variety of ways.
basically all of these systems are developed to be able to generate any type of information that is capable of satisfying and responding to user problems. That is, they become a simplified version where all the operations carried out in the company are presented:
- Transaction processing system: These computer systems are implemented for what is the management of everything that is related to the operational level of the company. It is a system that is responsible for process system transactions which stores and processes all transactions made during the day and that are essential to have for the proper management of the company.
- Management Information System: These SI are capable of being able manage and store all multi-level data with the aim of power create a clearer vision at the time of the decision making. His specialty is generate reports which provide information for operational management and what is the control of all activities in the process of company transactions.
- Business process control system: These systems are in charge of power monitor, manage and control any industrialization process that is carried out. It is in this kind of computer system where are they handled electronic sensors connected to computers in order to establish direct monitoring and at the same time power control all machinery processes.
How does a computer work? Understanding the basics of its operation
Usually the IF they enter the data through the input peripherals, in this case through keyboard or are extracted through output peripherals as it is the monitor or the horns. We also find the peripherals of “Entrance exit” that are in charge of carrying out both functions simultaneously, as is the case of the routers.
But to all thisWho is in charge of processing all this input and output data within the computer? The same are processed by the microprocessor or also known as CPU. What it mainly does is collect each of the data that is sent, there it is organized and then stored in order to turn them into an output element that are transformed into information that is understandable to the user.
It is also important to note that processing originates through a set of instructions received by the CPU where it tells you what to do. This is done through the keyboard or any other input component. The most important of this YES is that it is very flexiblewhich allows machines to be able to perform different activitiesfor this they only load storage programs.
