Communication Types

 

UNICAST COMMUNICATION

UNICAST COMMUNICATION IS A ONE-TO-ONE COMMUNICATION MODEL IN WHICH A SINGLE SENDER DELIVERS DATA TO A SINGLE RECEIVER. THIS IS THE MOST COMMON FORM OF DATA TRANSFER OVER NETWORKS.

UNICAST COMMUNICATION IS USED FOR A VARIETY OF APPLICATIONS, INCLUDING:


WEB BROWSING:

WHEN YOU VISIT A WEBSITE, THE WEBSITE SENDS A UNICAST PACKET TO YOUR COMPUTER.

FILE TRANSFERS:

WHEN YOU TRANSFER A FILE FROM ONE COMPUTER TO ANOTHER, THE TWO COMPUTERS SEND UNICAST PACKETS TO EACH OTHER.

EMAIL: 

WHEN YOU SEND AN EMAIL, YOUR COMPUTER SENDS A UNICAST PACKET TO THE RECIPIENT'S COMPUTER.

UNICAST COMMUNICATION IS A RELIABLE AND EFFICIENT WAY TO TRANSFER DATA. IT IS THE MOST COMMON FORM OF DATA TRANSFER OVER NETWORKS BECAUSE IT IS EASY TO IMPLEMENT AND IT USES THE LEAST AMOUNT OF BANDWIDTH.

BROADCAST COMMUNICATION

IN COMPUTER NETWORKING AND TELECOMMUNICATIONS, BROADCAST COMMUNICATION IS A METHOD OF COMMUNICATION IN WHICH A SINGLE MESSAGE IS SENT TO ALL DEVICES ON A NETWORK.

BROADCAST COMMUNICATION IS USED IN A VARIETY OF APPLICATIONS, INCLUDING:

ANNOUNCEMENTS: 

BROADCAST COMMUNICATION CAN BE USED TO SEND ANNOUNCEMENTS TO ALL DEVICES ON A NETWORK, SUCH AS SYSTEM MESSAGES OR NEWS UPDATES.

SYSTEM MESSAGES:

BROADCAST COMMUNICATION CAN BE USED TO SEND SYSTEM MESSAGES TO ALL DEVICES ON A NETWORK, SUCH AS UPDATES TO THE NETWORK CONFIGURATION OR SECURITY ALERTS.

STREAMING MEDIA: 

BROADCAST COMMUNICATION CAN BE USED TO STREAM MEDIA TO ALL DEVICES ON A NETWORK, SUCH AS LIVE TELEVISION OR RADIO BROADCASTS.

FILE SHARING: 

BROADCAST COMMUNICATION CAN BE USED TO SHARE FILES WITH ALL DEVICES ON A NETWORK.

___________

MULTICAST COMMUNICATION

MULTICAST COMMUNICATION IS A TYPE OF NETWORK COMMUNICATION WHERE A SINGLE SENDER CAN TRANSMIT DATA TO MULTIPLE RECEIVERS SIMULTANEOUSLY.

MULTICAST CAN BE USED IN A VARIETY OF APPLICATIONS, INCLUDING:

STREAMING VIDEO: 

MULTICAST CAN BE USED TO STREAM VIDEO TO MULTIPLE DEVICES, SUCH AS TVS, COMPUTERS, AND SMARTPHONES.

FILE SHARING: 

MULTICAST CAN BE USED TO SHARE FILES WITH MULTIPLE DEVICES.

VIRTUAL MEETINGS:

MULTICAST CAN BE USED TO HOLD VIRTUAL MEETINGS WITH MULTIPLE PARTICIPANTS.

GAMING: 

MULTICAST CAN BE USED TO PLAY GAMES WITH MULTIPLE PLAYERS.

MULTICAST COMMUNICATION IS MORE EFFICIENT THAN BROADCAST COMMUNICATION, AS IT ONLY SENDS THE DATA TO THE DEVICES THAT NEED TO RECEIVE IT. THIS CAN SAVE BANDWIDTH AND IMPROVE PERFORMANCE.

DIFFERENCE BETWEENS


______________


Broadcast

Multicast

Unicast

Sends a single packet to all devices on the network.

Sends a single packet to a group of devices that have expressed interest in receiving the packet.

Sends a packet to a single device.

Used for applications that need to reach all devices on the network, such as announcements and system messages.

Used for applications that need to reach a group of devices, such as streaming video or file sharing.

Used for applications that need to reach a single device, such as web browsing or file transfers.

Can be inefficient if there are a lot of devices on the network that do not need to receive the packet.

Can be more efficient than broadcast if there are a lot of devices on the network that need to receive the packet.

Is the most efficient way to send a packet, as it only sends the packet to the device that needs to receive it.

TCP/IP MODEL

  HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...

Internet Protocol (IP) Address

  IP ADDRESS IT IS A UNIQUE ADDRESS THAT WE CAN ASSIGN TO DEVICE .SO THAT DEVICECAN COMMUNICATE WITH EACH OTHER. WE CANNAOT ASSIGN SAME IP ADDRESS IN ANY TWO DEVICES IN OUR NETWORK. IF WE WILL DO THIS THEN IT WILL BE  CAUSE A CONFLICT ERROR. TWO VERSION OF IP ADDRESS: 1: IPV4 ; 2: IPV6 ; IPV4 32 BITS AND IPV6 128 BITS. AN IP ADDRESS, OR INTERNET PROTOCOL ADDRESS, IS A SERIES OF NUMBERS THAT IDENTIFIES ANY DEVICE ON A NETWORK.  COMPUTERS USE IP ADDRESSES TO COMMUNICATE WITH EACH OTHER BOTH OVER THE INTERNET AS WELL AS ON OTHER NETWORKS. TO FIND THE IP ADDRESS CLASS WE NEED TO LOOK AT THE FIRST DIGIT OF THE IP ADDRESS. AND BY LOOKING AT THE FIRST DIGIT, WE CAN GUESS THE SUBNET MASK TO WHICH CLASS IT BELONGS. CLASS A IP ADDRESS SUBNET MASK 255.0.0.0 CLASS B IP ADDRESS SUBNET MASK  255.255.0.0  CLASS C IP ADDRESS SUBNET MASK 255.255.255.0 IANA TABLE IP RANGES                 IANA   ( Internet Assigned Numbers Au...
