May you explain step by step in the questions below:

$1.$ WHat is the maximum number of hosts allowed in a subnet with a subnet amsk of $255\mathrm{.}255\mathrm{.}255\mathrm{.}224?$

$2.$ what is the broadcast address in a subnet with IP addresses $192\mathrm{.}168\mathrm{.}1\mathrm{.}0$ and a subnet mask $255\mathrm{.}255\mathrm{.}255\mathrm{.}192?$

$3.$ How many subnets and hosts per subnet are possible with the network address $192\mathrm{.}168\mathrm{.}10\mathrm{.}0/27?$

$4.$ Given a class B network, address $172\mathrm{.}16\mathrm{.}0\mathrm{.}0$ and a subnet mask of $255\mathrm{.}255\mathrm{.}248\mathrm{.}0(/21)?$

$5.$ You have Class C network address $192\mathrm{.}168\mathrm{.}1\mathrm{.}0$ and need to create at least $6$ subnets. What is the minimum subnet mask you should use?

$6.$ If a Class B network address $172\mathrm{.}16\mathrm{.}0\mathrm{.}0$ is subnetted using a $/28$ subnet mask, what is the increment between each subnet?

$7.$ How amny bits are borrowed for subnetting in Class A networks using a subnet mask of $255\mathrm{.}255\mathrm{.}224\mathrm{.}0(/19)?$
