$2$ hi i have a question regarding networks $($a$)$ A network address $210\mathrm{.}100\mathrm{.}56\mathrm{.}0$ is subnetted to create subnets with $30$ usable addresses. Determine the $($i$)$ Default network mask $($ii$)$ Number of bits used to create the subnets $($iii$)$ Total number of subnets $($iv$)$ Subnet mask $($v$)$ First address of host in subnet number $1($vi$)$ Broadcast address of subnet number I $($vii$)$ Last address of a host in subnet number $1($b$)$ Determine the throughput in slotted ALOHA for the following values of G : $($i$)0\mathrm{.}5($ii$)1\mathrm{.}0($iii$)2\mathrm{.}0($c$)$ Based on your results in $($b$),$ comment on the variation of throughput as G increases. Question $4($a$)$ Describe the TCP $3-$way handshake for establishing a connection. $($b$)$ Determine the types of the following destination addresses: $($i$)4$A: $30$: $10$: $21$: $10$: $1$A $($ii$)47$: $20$: $1$B: $2$ E: $08$: EE $($iii$)$ FF:FF:FF:FF:FF:FF $($c$)$ Determine the required window size in the communication illustrated in Figure $4\mathrm{.}1$ Figure $4\mathrm{.}1($d$)$ The format of the Ethernet frame is shown in Figure $4\mathrm{.}2.$ If the frame is transmitted through a $10$ Mbps Ethernet network, determine the time it takes to transmit the packet.
