Consider the a small university network shown in the figure above comprised of $3$ types of hosts. Suppose that the institutional link has a connection to the Internet that supports $250$ Mbps downstream transmission rate and $200$Mbps upstream transmission rate. Suppose that the Ethernet networks $($B and C$)$ can support a transmission rate of $1$Gbps $($both upstream and downstream$)$ and the WiFi network $($A$)$ can support a transmission rate of $150$Mbps $($both upstream and downstream$).$ Assume that the rest of the Internet $($not shown in the figure$)$ and the backbone connections between Ethernet switch and router have ample capacity, which can support any transmission rate $($both upstream and downstream$).$ Hosts in Networks B and C are connected through Ethernet while Hosts in Network A are connected through WiFi. There are $10$ hosts in Network A$,15$ hosts in Network B and $5$ hosts$/$servers in Network C$.$

Answer the following three questions $(1$ mark for each$)$

$1)$ Assumes that all servers in Network C and all host in Network B are idle. If all hosts in Network A are downloading large files from the Internet simultaneously and each host gets an equal share of the available bandwidth, what is the maximum throughput that any host in the university network A can experience?
