What is computer network ? Types of communication.

Computer Network

A computer network is a system in which multiple devices are connected to each other to share information and resources.

Types of communication:-

(I)Unicast:-

One to one communication between two devices in a network Known as Unicast.In this type of communication,there is only one sender and also one receiver .

(II) Multicast:-

Multicast happens when one user sends message to multiple users at the same time.In this case,there is only one sender and multiple receivers.

(III) Broadcast:-

Broadcast happens when one user is sending message to all users connected or in range .In this case ,there is one sender and all others are receivers.

Let's understand with an suitable example:-

-In Unicast transmission,John is sending information and Sohail is receiving the information.so,there is one sender and one receiver.

-In multicast transmission,Hari is sending the information whereas Pintu,Bunty,Sohail are Receiving the the information.so,there is one sender and multiple receivers.

-In broardcast transmission,Kishore is sending the information and everyone else is receiving.so,this type of communication is called broadcast.

TCP/IP Model

TCP/IP stands for Transmission control protocol/Internet protocol.TCP is a transport layer protocol and IP is a network layer protocol .TCP and IP both are different protocol but by the help of these two protocol ,TCP/IP model was developed.TCP/IP model defines how data is transferred from one computer to another.When two devices communicates with each other through the help of internet ,it is possible only for TCP/IP model .The TCP/IP model consists of 4 layers.These are :- (1) Application layer:- -This layer performs the function of the top three layer of the OSI model,i.e.Application layer , presentation layer and session layer . -The application layer is the top-most layer of the TCP/IP model. -The application layer provides the user with the interface to communication. -There are several protocols used by the application layer for interaction such as:FTP,HTTP, SMTP,DNS,TELNET etc. -The application layer sends data to transpo...

MAC Address

MAC stands for media access control. MAC address is also known as physical address or hardware address or BIA(burnt-in-address).BIA is generally written in Cisco router switches.physical address is generally written in laptop/pc.MAC address is generally written in Mobile. MAC address is globally unic.The MAC address of a device is different from other devices.Many people are thinking there is only one mac address of a device but it is actually wrong ,Because there is no mac address of a laptop .There is a Mac address of your NIC(network interface controller) ,which is connected to your laptop . (NIC) If you change your NIC,then the Mac address of your laptop will be changed.NIC is a separate hardware component present in your computer used to connect with the network (home network or internet).There are so many ways that you can connect your laptop with the network like...

Difference between Hub and Switch

Hub is a networking device which operates on physical layer of the OSI(open system interconnection) model whereas switch is also a networking device but it operates on data link layer of the OSI model .Hub is purely hardware but switch is a device which is the combination of both software and hardware.Hub supports broadcast transmission whereas switch supports Unicast, multicast and broardcast transmission .Hub is having single collision domain whereas Every port of Switch is separate collision domain.Transmission mode of hub is half-duplex whereas transmission mode of switch is full-duplex.Hub can do only forwarding whereas Switch can be able to do both forwarding and filtering.Hub can't store MAC (media access control) address where as switch stores MAC address.
