Networks and systems: What are they

Network operating systems or also known as Network Operating System, are considered as some software components of a computer capable of handling a series of resources on a network with more computers.

All this has become extremely important for the majority of users since through this system different network management and maintenance tools can be carried out, among many others functions.

Due to the importance of networks and systems within society and all its capacity in computing here we are going to teach you a little more about what they are, what are their types and what they are really designed for.

Network and systems What are they in computing and how are they different? ?

Red y sistemas ¿Qué son en informática y en qué se diferencian?

A computer network is defined as two or more computers that connect to each other and share resources, files, applications, hardware, among others. This allows several users to exchange information in a very simple, fast and very low cost way. All this has facilitated communication between companies, workers , thus reducing expenses significantly and taking care of the security of information data.

In other words, a network is referred to as a set of nodes that can communicate with each other at high speed. While a system is the WWW . Where there are clients and servers that offer a service within the network and these systems operate on computer networks.

We can find the following differences between these two terms:

  • A Network consists mainly of a group of computers that access the files and resources of one or more servers , but each of the machines is running its own processes .
  • In the case of workstations this does not become a burden for the system, since when executing everything independently as applications and tasks, the server is dedicated exclusively to control the storage and recovery of data.
  • A system corresponds to a mini or large computer that is responsible for centralizing all processing , that is, it is responsible for carrying out any type of task, be it data processing, file access, data transfer, among others.

Types of computer networks How many are there and which are the most important? ?

Computer networks are divided into different types according to their use, ownership, location and type of access, for this purpose here we explain each of these types:

By its use

  • Exclusive networks: Those that connect two or more points exclusively, that is, that they are deprived either for security purposes, to maintain their speed or because of the absence of other types of networks.
  • Shared networks: Those where you can join a large number of users without any restrictions.

By its properties

  • Public networks: They usually belong to state agencies and are available to anyone, they are freely accessible.
  • Private networks : These are usually provided by people, companies or associations and can be accessed only with the authorization of their owners.

By its location and coverage

  • Local area networks (LAN): Those where computers are connected to each other at small distances not greater than 10 meters and usually connect home or office machines.
  • Metropolitan Area Networks (MAN): They consist of several LAN networks and They tend to be much more extensive than these, covering much wider distances.
  • Wide area networks (WAN): Are those that cover more extensive areas in cities and that are available for a lot of equipment.

By the type of access

  • Wireless: The devices connect to the network through electromagnetic waves that are transmitted through the air and that is called how to carry connections without the need to make use of cables.
  • By cable: Computers are physically connected to each other through a wiring that provides the signal.
  • >

  • Wireless and cable combination: In this case the network has a wireless access point such as WAP and a point with cable connections.

It is important to mention that a system is a set of parts that interact with each other with a main objective and its parts are the hardware and software . There are different types of systems that are extremely important and which we present below:

  • Management information system: They are aimed at solving business problems. Where the GIS or MIS, differs from common information systems because they use other methods they use in the operational activities of the organization.
  • Transactional system: Transactional system, a transaction processing system, is primarily designed to be able to collect information, store, modify and retrieve any type of data that is generated by an organization’s transactions. A transaction is a process that generates or modifies the information that is stored within an information system.
  • Decision support system: Called as Decision support system (DDS ), which is a computer system used to serve as support, rather than to automate the decision-making process.
  • >

  • Strategic systems: Its main function is not to support the automation of operational processes or to provide any type of information to support decision making. In addition, it is trained to achieve advantages that competitors do not possess, such as the advantages in costs and services in business entries.
