HUB

 

WHAT IS HUB

A HUB IS A NETWORK DEVICE USED TO CONNECT MULTIPAL COMPUTERS IN A NETWORK.

ALL INFORMATION IS SENT TO THE HUB AND AUTOMATICALLY SENT TO EVERY PORT ON EVERY DEVICE.

HUB IS A LESS EXPENSIVE, LESS INTELLIGENT, LESS COMPLICATED.

HUB GENERALLY USED TO CONNECT A COMPUTER IN A LAN.

TRANSMISSION MODE OF HUB IS HALF DUPLEX.

ADDVANTAGES OF HUB

1. THE HUB CAN BROADCAST THE MESSAGE.

2. IT IS LESS EXPENSIVE THAT ANYONE CAN USE IT.

3. IF EVEN A PC GOES DESTROY, YOUR INTERNET WON'T BE A PROBLEM.

4. EASY INSTALLATION.

DISSADDVANTAGES OF HUB

1. THE HUB IS FAILED THE ENTIRE NETWORK WILL BE FAILED.

2. WE CANNOT SEND THE PRIVATE DATA THROUGH WITH HUB.

3. HUB DOES NOT PROVIDE ANY SECURITY.

4. HUB CANNOT SUPPORT FULL DUPLEX TRANSMISSION MODE.

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...
