What are the differences between an Ethernet switch and an
Ethernet hub?
Give this one a try later!
The main function of the internet layer is to move data from the source to its
destination, or set of destinations, regardless of where the destination exists.
The internet layer performs this function by using a unique logical address and a
standard set of protocols to help forward data based on the addressing scheme.
, Although a number of protocols have been used, the internet protocol (IP) is
used almost exclusively today
With a network prefix length of 25. the 1st 25bits (3 octets + 1 bit) are the network
portion.
The network ID for the 1st three octet would be the same as the IP address,
which is 192.168.1.
The last octet of the IP address (145) is binary 10010001. The last octet of the IP
address mask is binary 10000000. The last octet of the network ID is the result
of the operation of 10010001 AND 10000000, which is binary 10000000 (128).
Therefore the network ID is 192.168.1.128.
to receive, process, and transmit user application traffic using the forwarding
tables that were populated by the control plane
An ethernet switch can provide full duplex capabilities on point to point
interfaces. An ethernet switch can make an intelligent forwarding
decision and send frames only to the port that needs to receive them
The hub on the other hand, provides half-duplex capabilities and collisions
can occur. Any ethernet frame that arrives on a port is automatically
forwarded out to all other ports
