Tcp Vs Udp

 

TCP VS UDP

TCP (TRANSMISSION CONTROL PROTOCOL) AND UDP (USER DATAGRAM PROTOCOL) ARE BOTH TRANSPORT LAYER PROTOCOLS THAT ARE USED TO SEND DATA OVER A NETWORK. HOWEVER, THEY HAVE SOME KEY DIFFERENCES.

TCP

CONNECTION-ORIENTED: TCP ESTABLISHES A CONNECTION BETWEEN THE SENDER AND RECEIVER BEFORE SENDING ANY DATA. THIS ALLOWS TCP TO ENSURE THAT ALL DATA IS RECEIVED IN THE CORRECT ORDER AND WITHOUT ANY ERRORS.

RELIABLE: TCP PROVIDES RELIABLE DELIVERY OF DATA. THIS MEANS THAT TCP WILL RETRANSMIT ANY DATA THAT IS LOST OR CORRUPTED DURING TRANSMISSION.

SLOW: TCP IS SLOWER THAN UDP BECAUSE IT HAS TO ESTABLISH A CONNECTION AND SEND ACKNOWLEDGMENTS FOR EACH PACKET OF DATA THAT IS SENT.

HEADER : TCP PACKET HEADER IS 20 BYTES.

PROTOCOLS USED IN TCP.

WEB BROWSING

EMAIL

FILE TRANSFERS

TELNET

FTP

UDP

CONNECTIONLESS: UDP DOES NOT ESTABLISH A CONNECTION BETWEEN THE SENDER AND RECEIVER BEFORE SENDING ANY DATA. THIS MAKES UDP FASTER THAN TCP, BUT IT ALSO MAKES IT LESS RELIABLE.

UNRELIABLE: UDP DOES NOT GUARANTEE THAT ALL DATA WILL BE RECEIVED IN THE CORRECT ORDER OR WITHOUT ANY ERRORS.

FAST: UDP IS FASTER THAN TCP BECAUSE IT DOES NOT HAVE TO ESTABLISH A CONNECTION OR SEND ACKNOWLEDGMENTS.

HEADER : UDP PACKET HEADER IS 8 BYTES.

PROTOCOLS USED IN UDP.

ONLINE GAMING

LIVE STREAMING

VOIP

DNS

DHCP

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...
