Answer:
The decimal value of 101₂² base 2 = 25 base 10
Explanation:
The number 101₂² in decimal value is found as follows;
101₂ × 101₂ = 101₂ + 0₂ + 10100₂
We note that in 101 + 10100 the resultant 2 in the hundred position will have to be converted to a zero while carrying over 1 to the thousand position to give;
101₂ + 0₂ + 10100₂ = 11001₂
Therefore;
101₂² = 11001₂
We now convert the result of the square of the base 2 number, 101², which is 11001₂ to base 10 as follows;
Therefore converting 11001₂ to base 10 gives;
11001₂= 1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2 ¹ + 1 × 2⁰
Which gives;
16 + 8 + 0 + 0 + 1 = 25₁₀.
Answer:
I would reset the Domain Name System (DNS)
Explanation:
One factor that could lead to the "Site Cannot Be Reached" error is DNS "poisoning". Another is invalid DNS cache. Both can be caused by an attack on the system by people trying to spoof the system. Spoofing ensures that even when the right address is entered, it leads one to another web address.
One way to quickly reset the DNS is to run ipconfig /flushdns
This helps to clear the DNS cache.
Once the DNS cache has been successfully flushed, the system returns a confirmatory message that reads “flushed the DNS resolver cache”.
The systems administrator can now proceed to reconfigure the IP address(es)

Answer:
Network Address Translation (NAT)
Explanation:
With the aid of Network address translation(NAT), the IP addresses of a particular local network are translated or mapped into a single or multiple global or public IP addresses. Therefore, a wireless router could use NAT to translate its private IP address on internal traffic (network) to a routable address for the internet.
With NAT, businesses can use many internal IP addresses since they are just for internal purposes and will be eventually converted into a single or a few multiple routable IP addresses.
Three types of NAT are possible:
(i) Static NAT : There is a one - to - one mapping between private IP addresses and routable (public) IP addresses. One private IP is mapped to one public IP address.
(ii) Dynamic NAT : There is a many- to - many mapping between private IP addresses and routable (public) IP addresses. Multiple private IPs are mapped to many public IP addresses.
(iii) Port Address Translation (PAT) : Many - to - one relationship between the private IP addresses and public addresses. Many private IP addresses can be mapped or translated into a single public IP address. This type of NAT is also called NAT overload.
