Hi can you please help me with this. The network pictured below represents the layout of computers in a wired office layout. All possible wiring paths are shown. $($Some obstacles exist between computers that eliminate some possible paths.$)$ Each node is the location of a PC and the branches represent cables connecting the computers. The number on a branch indicates the length of the path in meters. $($NOTE: The figure is not drawn to scale.$)$

Scenario I: Suppose that Node $1$ is the entry point for a cable system that will tie all the computers together into one network.

$1.$ For Scenario I described the sentence above, in new lines entered below this part, state the specific type of network flow problem this is$.$

$2.$ Start from Node $1.$ Determine, by manual calculation, the minimum total amount of cable that would be needed to link each and every individual computer into a single network.

In lines inserted below, you MUST present HERE your full and complete step$-$by$-$step manual solution to Scenario I. Scanned images of hand$-$drawn figures are acceptable.

$3.$ In new lines entered below this part, present a drawing HERE of the final network representation for Scenario I showing only the routes

Scenario II: Suppose now that Node $1$ is a server that needs to be connected to each and every individual PC$.$ The cable system used requires each PC to have a unique connection.

$4$ For Scenario II described above, in new lines entered below this part, state the specific type of network flow problem this is$.$

$5.$ Start from Node $1.$ Determine, by manual calculation, the minimum total amount of cable that would be needed to connect each and every individual computer to the network server.

In lines inserted below, you MUST present HERE your full and complete step$-$by$-$step manual solution to Scenario II$.$ Scanned images of hand$-$drawn figures are acceptable.

$6.$ In new lines entered below this part, present a drawing HERE of the final network representation for Scenario II showing only the routes that are used.
