When we use a computer, it works because it is made up of a series of computer elements , starting with what is the operating system. In order to understand how this OS works, it is first necessary to know what a computer system is and how it is constituted.
It is important to keep in mind that the computer system has now become a very important part for the human being, taking into account that currently all or almost everything is managed to through 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 is it, what is it for? and how does it work? 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 SI, is a system that is responsible for storing and processing the information that is generated on a computer For this it has a set of interrelated parts such as the hardware, software and the user. All of them are necessary for the team to be functional for the human being.
Taking into account that it is the user who requires the processed information and, in addition, is the one who has the absolute control over everything that happens or is carried out in the system. Therefore, the YES has the function of collecting all the data, processing them and then transmitting all the information once it has 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 are completely necessary for its execution. In this way, he is in charge of being able to manage hardware resources and in turn being able to control all applications so that the user can obtain the best results.
That is why here we will explain each of its parts, such as the hardware, software and firmware .
Software
This component of the YES is made up of a set of programs that have been created to carry out a specific action within a system. These actions can be performed by the same computer companies or simply be carried out by users .
In other words, it is the programs that are responsible for giving instructions to the computer so that it 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, a software is not only made up of the programs , but also the user information and all the data that is processed , all this is intangible, that is, that none of this we can see or touch.
Hardware
Unlike software , when we refer to hardware we are simply talking about everything we can see and touch on a computer. Therefore, this refers to the physical parts of the PC , such as chips, printers, cables, monitor, plates, integrated circuits, hard disk >, among many other elements.
Therefore, the computer is a computer that is in charge of constantly processing information in in a very short time . Where it requires both the software instructions which are performed by one of the devices connected to the equipment, in that case the hardware . Typically, these components fulfill the following functions: inputs, processing, storage and data output .
Firmware
It is present on any computer that is composed of both hardware and software. It refers to a series of instructions of a computer program that is stored in flash memory or ROM . These instructions are responsible for setting a logic at the time of controlling the circuits of some device.
This is how the firmware is an element of the hardware , because it is integrated into the electronics. However, it is also considered a part of the software , since 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 giving the system the routines of its operation and the answers regarding the requests it constantly receives and which must be made to meet the needs and demand of users . It is also responsible for creating an interface so that the system configuration can be done quickly and finally control and manage the system boot on the computer .
What are the different types of computer systems that exist?
Nowadays 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. Given that without them, almost no activity could be performed.
Due to all the functions that 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 to classify the SI that currently exist:
- 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 making , and it can be used by a management to solve problems and be able to choose the most viable option and be able to predict what the future scenarios are and thus be prepared to any eventuality:
- Business collaboration system : Also known as Enterprise resource planning or by its acronym ERP , they are a business collaboration used by most companies around the world, as it makes it easier for different companies to to manage all the information that circulates within the company .
- Executive information system : This system is able to provide users with immediate access to all critical information that is handled within the company , either from external or internal sources . All this information is usually presented in a varied way.
Basically all 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 performed 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 processing the transactions of a system that stores and processes all the transactions made during the day and that are essential to have for the proper handling of the company.
- Management Information System: These SIs are able to manage and store all multi-level data in order to be able to create a clearer vision at the time of decision making . Its specialty is generate reports which facilitate the 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 responsible for monitoring, managing and controlling any industrialization process that is carry out. It is in this type of computer system where the electronic sensors connected to the computers are handled so that can establish direct monitoring and at the same time be able to control all machinery processes .
How does a computer work? Understanding the basis of its operation
In general, the SI enter the data through the input peripherals, in this case through the keyboard or are extracted through the peripheral output > as is the monitor or the bugles . We also find the peripherals of “Input / Output” that are responsible for performing both functions simultaneously as is the case of the routers.
But to all this , who is in charge of processing all this input and output data inside the computer? The same are processed by the microprocessor or also known as CPU. This is what it mainly does is to collect each of the data that is sent, there they are organized and then stored so that they can be converted into an output element that are transformed into information that is understandable to the user.
It is also important to keep in mind that the processing originates through a set of instructions that the CPU receives, where it tells you what to do. This is done through the keyboard or any other input component . The most important thing about this YES is that it is very flexible , which allows the machines to be able to perform different activities , for this they only load storage programs.
