what is Network Architecture?

            Network architecture is the complete fundamental structure of a communication  network.A network architecture provides complete layout of the established network with detailed view in proper manner.It may contains the objects that hardware devices which are used for communications,and network topologies which is applied in network.

           This Network architecture is normally designed by network engineers or network administrators before building a network.so i hope all of  you understood that all the networks are now formed by preplanned architecture in proper manner.
           Here am going to explain you about  Network Architecture with example diagram.
There are three network architecture is defined based on that communication and usage.
         1.)Peer to Peer(P2P) Or Point to Point Architecture?
        2.)Client-Server Architecture?

  What is Network?

                   Network is collection of interconnected devices which is capable to communicate with each others through the communication path ways.

                 In a Network the devices can be any hard wares such as computers, Printers, Telephones etc…

               In Network Communication between any devices can be possible only through a medium such as Ethernet cables, WI-Fi, Bluetooth, infrared etc…

                 The main purpose of the network is sharing resources. Now a day’s in the world the usage of network is growing efficiently. There are so many features we are getting from networks.If you connect your PC to a network at multiple network locations using ISP service then you can share any files, folders,then you can send mails,you can take backup of your data to any Network drives.

                There are two aspects for setting up a network,the first one is the hardware(cable,WiFi,infrared..etc) which is used to connect the devices (computers,printers...etc)together as network,the second one  is the software(browsers,messengers,firewalls,antivirus,...etc) which is installed on the device  should allows them to communicate with each other.

                You can Login your authorized PC  remotely if it is connected within the  network.When network becomes open sourced then it can be managed by online Collaboration soft wares.

               

              In this picture there are some desktop PC, two laptop, a server which is physically connected via cable to that switch.

              So in this pics all the devices can communicate with each other and all are connected via a medium (Ethernet cable), so we can call this is architecture as a ‘Network’.     Read More...

What is Disadvantages of Network?

Disadvantages of Network:-

Disadvantages of Network? 

     * Expensive:

               Normally Netwok will save money at every time.But the devices used for network which cost expensive.For installation network may require service technician.                         

     *Administrator:

                  How ever the network requires network administrator for proper maintanence.Because without technical skills it is too difficult to manage and find faults in a entire  network for a normal user.

     * Hacking:

                 This is the most important thing in internet is to be aware.When you connect your pc to network it is open pc for hacking.so a network need strong security like firewalls,antivirus,monitoring tools to avoid such cases.

     * Virus:

                 Network is best medium for spreading of virus from one pc to other pc.

Virus leads your pc down or it will affect your data.so in can be filtered by only up to date antivirus softwares,or firewalls. 

     * Network traffic:

              A well planned network required well routing also.Network traffiic should be managed in proper manner.Other wise it will affect data transfer rate of your network.It leads poor access performence.             

What is Advantages of Network?

Advantages of Network:-

Advantages of Network?

         

      *Resource Sharing:               

                                  Which means antivirus any informations,softwares, application softwares,hard wares such as printers, faxes, modems also can be shared over network.so any authorized users can access those resources without any problem.very large amount of data also can be stored easily with very less time consuming.

      *Security:

                          The Data  which are stored in any server which is password protected.so it can be accessed by only authoized users and it can be modified by only privillaged users,so there is no worry about any un autorized modifications on data.                    

      *Centralized Managements:

                           Software or any Latest updations for any clients which is possible from server side.It can be installed by server to all clients simultaneously.It avoids that need to spent time and energy for installing or updating softwres for individualcomputers independently.           

      *Speed:                       

               Data can be shared very short peoiods.The network data transfer speed that depends upon the hardware(Ehternett,wi-fi,bluetooth...etc) whcih is used to connect devices togother.Emais are delivered within a second.

       *Easy Administrating:

                            A well designed network required considerable time and expertise for proper maintanence.that network enables the network administrator to manage network easily.

      *Multible Access:

                           Network allows multiple user to access same file simultaneously,So If you consider a company,there all project members can work together in a same file.
