What is Flow Control? What is Congestion Control? What is the main difference between H low Control and Congestion Control?

With longest prefix matching $($the forwarding table is shown in the below$),$ a packet with destination address $11001000000101110001011010100001$ will be forwarded to link interface

A packet whose id is $200$ with a size of $5,250$ bytes arrives at an IP router with an MTU of $1,500.$ As the packet size is greater than that of the MTU, it needs to be fragmented. Show all fragments with their header information $($like we did in the elass$).$ Where will these fragments be reassembied?
