Introduction Types of Computer Network

 

What is a Computer Network?

Computer networks is bunch of computers connected through optical cables, wires and fibers so that it interacts with each other through networks. The goal is to share the content and the information among the system of same network or other. In computer networks there are different types of networks that shares the information among each other they maybe simplex or complex ones.


Computer Network Components Includes:-

  1.  National interface card 
  2.  Hubs
  3.  Switches
  4.  Modem
  5.  Routers
  6.  Cables & Connectors

Major components of a computer network are:

NIC(National interface card)

NIC is a device that helps out the network to reach proper address .As It contains Hardware address which provides a reference to the network after that network eventually checks whether the address of input given by client matches with that hardware address or not once it matches network gets connected. The Data-Link Layer of the network analyze this address to connect the system or to identify the network attached in the newtork.

There are two types of NIC:-

  1. wired eg:- wired computers connected in some topology
  2. wireless eg:- laptops

Hub

Hub is like a junction from where the data packets travels to all interconnected PC's where data is stored once the computer requests from the information that requests gets into the hub after that hub will splits that requests into the interconnected PC's so Hub is just a connection of many different interconnected PC's.

Switches

Switch is far better than hub as it sends data from directly source to destination. On the other hand hubs sends data or broadcast the data on all the interconnected devices switches directly sends the data to the proper destination.

Router

Routers are basically used for connecting different or distinct networks or to connect LAN to Internet LAN means Local Area network.

Modem

Modem connects computer with the Internet over the existing telephone connections. It is separate component used to access internet or connect the computers.

Detailed Analysis on Arduino UNO R3

Arduino UNO R3 Arduino Uno is a microcontroller board based on ATmega328P . It has 14 digital input/output pins 6 Analog pins a 16 MHz quartz crystal oscillator with USB connection ,a power jack , an ICSP(In-Circuit Serial programming) header and a reset button actually it has two reset buttons . Also Arduino uno has RX-0,TX-1 that is receiving and transmitting pins on board. Arduino uno contains  AREF pin which means Analogue-Reference IOREF pin this pin is provides a voltage  reference at which the microcontrller works 3-ground pins 3-Vcc pins Basically the purpose of creating an Arduino Uno is to Control the sensors and the actuators so that it can work accordingly the data which we provide with the help of software . Nowadays people using Arduino Uno in many fields it has very huge scope in  the field of  IOT(Internet Of Things). Also in my current project which is 2D-printer we have used Arduino Uno which sense the Data and according...

how to make a static IP Address of an Raspberry-pi

How To Make Raspberry-pi ip-Address Static and show an virtual window of raspberry-pi on Windows desktop through VNC-Viewer STEP  1: Disconnect your Desktop from Windows operating system. STEP  2: Connect your Raspberry-pi to your pc install the Raspbian from the below link STEP  3: Download BalenaEtcher which is basically an image flasher which is going to flash the image of the OS that is Raspbian on the SD card on any USB  for further details go to the link below and download it. Also you can download Win32diskmanger to flash the OS STEP  4: Now as we download the Raspbian and also we flash it now Download the VNC viewer through the below link  STEP  5: Now open the Terminal on Rasberry-pi and write the following commands 1. ifconfig : Check out the  ip-address , sub-net mask 2. netstat -nr : This command will tell you about the  gateway address 3. sudo nano /etc/network/interfaces : This command will give the netwo...
