Definition of Computer Network: Benefits, Objectives, Types, Topology

A personal computer network is a telecommunications network that allows computers to exchange data. Purpose according to the personal computer network means that in order to be able to achieve its goals, on the part of each commuter network is able to provide and request services (services). The party who receives/requests the service is considered to be using the client and the one who delivers/requests the service is considered to be with the server. The design was called the client-server system, and was used in almost all implementations of personal computer networks.

Two computers, each with a network card, then connected by cable or wireless to make the medium of data transmission, and there is a network operating system software that will create a simple commuter network. If you want to create a computer network that has a wider range, then an additional tool is needed, for example, Gateway, Hub, Switch, Bridge, Router for interconnection tools.

The following is the definition of computer networks according to experts & several other media that have been summarized by the weblog taken some of the origins that can be seen below.

  • Melwin Syafrizal (AMIKOM Yogyakarta)

Computer Network is a set of “interconnections” between 2 or more autonomous computers connected using wired or wireless transmission media

  • Izaas el Said (personal computer networking expert )

The definition of a computer network is a system in which a personal computer that is connected to create coverage and power origin.

  • Madcoms

Computer Network is a cluster according to several personal computers and other supporting tools that are connected in one unit & interconnected

  • Techi Wire House

The definition of a personal computer network is the formation of 2 or more connected computers.

  • Big Dictionary and Expert

The definition of a personal computer network is a group according to 2 or more personal computer systems that are connected together.

  • English wikipedia

A personal computer network is a collection of several computers connected electroly.

  • Encyclopedia

The definition of a personal computer network is a system consisting of personal computers that are made to be able to spread the origin of power, communicate, & be able to access news together.

The benefits of Computer Networks in general that will be able to be obtained are the following

  • Computer Networks can share resources (data, events, computer peripherals)
  • Computer Network effective communication media & multimedia
  • Computer Networking allows for more efficient resource management.
  • Computer Networks allow for more unified delivery.
  • Computer Networks allow workgroups to communicate more efficiently.
  • Computer Networks can maintain more guaranteed data security (access rights).
  • Computer Networks save porto development and maintenance.
  • Computer Networks help maintain captions to stay reliable & up to date.
  • Network Destinations

    Here is the purpose of a computer network:

  • Networking enables more efficient power origin management
  • The network helps keep captions reliable & upto-date.
  • Networking helps speed up the process of deploying data (data sharing).
  • The network allows hordes to communicate more efficiently.
  • Networking helps businesses in serving their clients more effectively.

  • Types of Networks

    Here are the types of tissues based on their grouping.

    • Based on Operating Patterns

    Client-server is a network interaction that uses the principle of service & service.

    Peer to peer is a combination of several personal computers that are usually not poly connected in a network to connect, develop data (sharing) & use the resources (resources) of other computers as if it were a computer itself.

    • By Reach

    LAN (Local Area Network) is a personal computer network whose network only covers a small area; such as campus computer networks, buildings, workplaces, in residences, schools or more miniature.

    MAN (Metropolitan Area Network)

    The MAN network is a combination of several LANs. The range according to MAN is between 10 to 50 km, MAN is the right network to form a network between offices and workplaces in one city between factories / agencies & central workplaces that are within its reach.

    Wide Area Network is a computer network that covers a large area into a model, namely computer networks between regions, cities or even countries, or can also be defined as a personal computer network that requires routers & public communication channels.

    The Internet is a global or worldwide computer network. Because the Internet is a personal computer network that is connected worldwide, as a result communication & data or file transfer as easier.

    • Based on Transmission Media

    Is a personal computer network that uses cables as a conducting medium. In a network, transmission media plays a very important role, because facts or data will be transported through the transmission media. In Wire Network, there are several choices of cables that can be used, namely coaxial cables, twisted pair (TP) cables and fiber optic cables.

    Wireless is a type of computer network that uses data transmission media without using cables. The media used are radio waves, infrared, bluetooth, & microwave. Wireless can be used in LAN, MAN, and WAN networks. Wireless is intended for high mobility needs. Network Topology to Use

    In short, a computer network topology is a design based on a computer network, which determines how data packets and information are transmitted between personal computers on the network. For the creation of a local network (LAN), there are several topologies that can be implemented, namely:

    • Ring Topology

    Ring topology is one type of antique topology, but it is relatively effective for handling the creation of a local network of a small number of personal computers. Toplogy ring will allow a data packet or news to be accessed by the client’s personal computer in a specific ring cycle. So, a new coverage can be accessed by the client number 4, the completion of which the client is accessed numbers 1, 2, & also 3 first.

    • Advantage
    • Save cable, cheaper than star topology
    • Can avoid collisions of sent data archives because the data flows in one direction.
    • It’s easy to build.
    • All computers have the same status.
    • Loss
    • Sensitive to errors.
    • Network construction is more rigid, if the cable is cut off then all computers cannot be used
    • Bus Topology

    Bus topology is a type of topology that is quite cheap, because it only uses kebel & connectors to create a local network. The bus topology uses connectors & terminators to create a local network that can work.

    • Advantage
    • Save cables.
    • Simple cable layout.
    • If one computer is dead, it does not interfere with another computer.
    • Practically developed.
    • Loss
    • Error detection is very small.
    • Traffic is heavy so that there are often engravings of data archives that are sent.
    • If one of the clients is damaged or the cable is broken, the network will be damaged.
    • Star Topology
