Types of Network


What is a Network?

 A Network is defined as an arrangement of a set of devices connected together by communication links for the purpose of sharing data. Each device may be called as a node which can be a computer, printer or any other devices capable of sending or receiving data generated by other nodes or devices on the network.

 Following are the types of Network:-

 1.Local Area Network(LAN):

  • LANs are privately owned networks defined within a small physical area such as in a single office, building or campus.
  • LAN size is limited to a few kilometers for which the network management is simple. 
  • Most common LAN topologies are bus, ring, star and have data rates in the range of 4 to 16 megabits per second.
  • LANs often use a transmission technology consisting of a single cable to which all the machines are attached.
  • LANs are mostly used to allow resources to be shared among personal computers or workstations.
2.Metropolitan Area Network(MAN):

  • A MAN is designed to extend over an entire city.
  • It may be a single network such as cable television network or it may be a means of connecting a number of LANs into a large network so that resources can be shared LAN to LAN as well as device to device.
  • It might cover a group of nearby corporate offices or a city and might be either public or private.
3.Wide Area Network(WAN):

  • The WAN provides a long distance transmission of data, voice, image and video information over a large geographical area, that may comprise a country, a continent or even the whole world.

Configuring 2 backend servers and a load balancer with HAProxy

A load balancer is a device that distributes the traffic across a cluster of servers. In computing, load balancing improves the distribution of workloads across multiple computing resources, such as computers, a computer cluster, network links, central processing units, or disk drives.As a result, it improves responsiveness and increases the availability of applications.  For load balancing, we need to install LAMP server on backend servers and HAProxy on the load balancer. HAProxy is a free, open source software that provides a high availability load balancer and proxy server for TCP and HTTP based applications that spread requests across multiple servers. Here we will make two backend servers and one load balancer. At two backend servers enter the following commands— $sudo apt-get install apache2 $sudo apt-get install mysql-server $sudo apt-get install php libapache2-mod-php php-mysql $sudo gedit /var/www/html/index.html (Mak...

Network Connection verification and Troubleshooting commands in Windows

To ensure the proper network connection in the system, we do the following three types of checking: ---   Check the NIC card --- Check whether we have an IP or not or our gateway is active or not by a ping test -----  Check if the port no or the service is active or not To check the connection go to command prompt and enter the commands >ping localhost  then NIC  working. >ping 172.29.0.1 then gateway working >ipconfig In computing, ipconfig (internet protocol configuration) is a console application (command line tool) in Microsoft Windows used to control the network connections on windows.It displays all current TCP/IP network configuration values and can modify DHCP and DNS settings. Usually, ipconfig command is used with the command-line switch  /all. > ipconfig /all This command shows the various network configurations, MAC address, default gateway and IP addresses of different servers on the ne...

Fundamental Concepts of Arrays

  An   array   is a collection of elements of the same data type stored in   contiguous memory cells . It has a   fixed size   and is by default   passed by reference   to a function.  Eg. int arr[6] = {4, -3, 8, 5, -1, 6}; It initializes an integer array 'arr' storing 6 elements.  Assuming the size of an integer to be 4 bytes and base cell address to be 2000. It can be represented as -  A  dynamic array  is similar to a static array but it has the ability to  automatically resize  itself when an element is inserted or deleted.  They are available as  vectors in C++  and likewise l ists in Java .  Eg. list<int> l;      vector<int> v; Vectors are slightly less efficient than static arrays due to the occasional resizing and copying of elements.   The amortized time complexity of insertion in a dynamic array is O(1).  [Amortized Time complexity ...
