It means they cannot make changes inside those folders and they don't have permission to execute files within it.
We all know that there are 26 letters available in the alphabet and there are just 5 even numbers between 0 and 9. We are now given the situation of how many passwords can we make out of the criteria of having 5 letters that cannot be repeated and 4 even digits from 0-9. We cannot repeat the numbers and letters, thus our password will look something like this, LLLLLNNNN, where L is a letter and N is a number. Let us note that we cannot use the characters and digits more than once.This is how we will solve the probable number of passwords.
26 x 25 x 24 x 23 x 22 x 5 x 4 x 3 x 2
When we compute this formula, we will have the total number of possible passwords:
947,232,000.00
There are 947,232,000 possible passwords based on the given criteria.
<span>A DHCPv4 client use the broadcast IP address to send the initial DHCP discover packet when the client is looking for a DHCP server. </span><span>
A workstation will send a DHCPDISCOVER message to start the process of obtaining a valid IP address. The client does not know the addresses of DHCP servers, and that's why it sends the message via broadcast, with destination addresses of FF-FF-FF-FF-FF-FF and 255.255.255.255.</span>

Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec
