Answer:
There are certainly many hidden costs, and you need to find them out. I am listing some. The GPU can cost a lot if you are using them for complex computing like in the case of Bitcoin. You need to pay heavy electricity bills as well. And if you want to install the webserver then as well, you need to keep your computer open all the time, and pay a good sum as an electricity bill. Many more hidden costs can be found. And one out of above is used in Schools, the webserver. Some more hidden costs can be Network cost, as the school is big, and you need to connect all through LAN, and at times we also need WAN set up. And these are another hidden cost. Various education licenses come for free, and smart classes cost as well. The video conferencing, VOIP, etc costs as well. Smart classes training by various computer training institute for teachers like one from adhesive.

Answer:
a. 255.255.255.0 (class C)
b. 255.255.255.224
Explanation:
Here, we want to give the implied subnet mask of the given classful IPV4 address
We proceed as follows;
Given IPv4 address: 200.200.200.200
Classes
Class A : 0.0.0.0 to 127.255.255.255
Class B: 128.0.0.0 to 191.255.255.255
Class C: 192.0.0.0 to 223.255.255.255
Class D: 224.0.0.0 to 239.255.255.255
so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0
In CIDR(Classless Inter Domain Routing)
subnet /27 bits means 27 1s and 5 0s. so subnet
i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .
Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.
No, it is false. This is mainly because there would be no need.
The subnet mask can be utilized to segment the 172.16.0.0 network to qualify for a minimum of 6 subnets while maximizing the numeral of broadcasters per subnet is 255.255.224.0
<h3>What do subnet masks mean?</h3>
- A subnet mask is a 32-bit numeral formed by setting keeper bits to all 0s and developing network times to all 1s.
- In this way, the subnet mask divides the IP speech into the network and host addresses.
- A subnet mask is used to separate an IP address into two pieces. One element defines the host (computer), and the different part identifies the network to which it belongs.
- To better comprehend how IP lessons and subnet masks work, look at an IP speech and see how it's managed.
