Question $2$

In a corporate office, there are a total of $3$ departments e$.$g$.$ HR department, IT department,

Legal department. Now, each department is connected to exactly two other departments. Also,

each department is spread across $2$ floors, and $2$ floors within each department are connected

to a central hub. which includes a shared connection where $3$ computers are linked in a way that

allows them to communicate along a single pathway across each floor. Additionally, there is a

printer in each department connected to every computer using dedicated point$-$to$-$point

connection. Draw a hybrid topology and calculate the total number of links needed for this

topology. $[10]$
