What is the difference between hub switch and router

This preview shows page 6 - 10 out of 10 pages.

WHAT IS THE DIFFERENCE BETWEEN HUB , SWITCH AND ROUTER 1 - HUB : A HUB IS THE LEAST INTELLIGENT OF THE THREE HARDWARE DEVICES. IT SERVES AS A CONNECTION POINT FOR THE COMPUTERS (AND OTHER DEVICES SUCH AS PRINTERS) IN A NETWORK. A HUB SIMPLY PASSES ALONG THE TRAFFIC IT RECEIVES TO THE COMPUTERS CONNECTED TO IT. ANY TRAFFIC THAT GOES IN ONE PORT COMES OUT OF THE OTHER PORTS. AS A RESULT, ALL THE COMPUTERS RECEIVE THE TRAFFIC, EVEN IF IT IS NOT FOR THEM 2 - SWITCH : A SWITCH IS MORE INTELLIGENT THAN A HUB. AS A HUB, A SWITCH IS THE CONNECTION POINT FOR THE COMPUTERS (AND OTHER DEVICES) IN A NETWORK. HOWEVER, A SWITCH IS MORE EFFICIENT AT PASSING ALONG TRAFFIC. IT RECORDS THE ADDRESSES OF THE COMPUTERS CONNECTED TO IT IN A TABLE. WHEN TRAFFIC COMES THROUGH, THE SWITCH READS THE DESTINATION ADDRESS AND SENDS THAT TRAFFIC TO THE APPROPRIATE COMPUTER RATHER THAN SENDING IT TO ALL THE CONNECTED COMPUTERS .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
