uppose that a datagram of 2,700 bytes (20 bytes of IP header plus 2,680 bytes of IP payload) arrives at a router and must be forwarded to a link with an MTU of 900 bytes. Also suppose that the original datagram is stamped with an identification number of 15. How many IP fragments will be created by the router to forward this packet

Four (4) IP fragments will be created by the router to forward this packet.

Explanation:

Datagram = 2700 bytes

IP Header = 20 bytes

Maximum Transmission Unit = 900 bytes

Original datagram is stamped with an identification number of 15

Required number of fragments =

⇒  

⇒  2680 / 880 = 3.045

ceiling(3.045) = 4

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.
