1. Your boss has asked you to tell him how many usable subnets and hosts a Class C network with the IP address and mask of 195.66.52.0/28 can have. How should you respond
Answers
If the IP address of the Class C network is 195.66.52.0/28, the network has 16 subnets and 14 hosts per subnet.
Since it is a Class C network, the subnet mask will always be 255.255.255.0, and the last octet of the IP address will be 0. In the provided network, however, the subnet mask is /28, which means that the first 28 bits of the IP address are the network address, leaving 4 bits for the host address. In binary, the subnet mask is 11111111.11111111.11111111.11110000.
The number of bits reserved for the host address is calculated by subtracting the number of bits used for the network address from the total number of bits in the IP address:32 bits in total - 28 bits for the network address = 4 bits for the host address.
Since there are 4 bits for the host address, there are 2^4 possible host addresses, or 16 possible hosts per subnet. Since there are 16 possible hosts per subnet, and there are 16 possible subnets, the answer is that the network has 16 usable subnets and 14 usable hosts per subnet.

After how many years will India surpass China in terms of population, assuming that the annual population growth in neither of these two countries will change?

Answers
Code:
population_china = 1420062022
population_india = 1368737513
years = 0
while population_china >= population_india:
population_china *= 1.0035
population_india *= 1.0108
years += 1
print(years)
Output:
6
Explanation:
Using a while loop would probably be of greater use than a for loop since we are increasing the population growth of both countries until India's population surpasses China's population (so a condition needs to be set).
Looking at the code, we first set the original population of both countries in their own variables (population_china, population_india). We also set the 'years' variable at 0, which will increase with respect to the yearly population growths of both countries. In the while loop, the condition population_china >= population_india will allow for the variable 'years' to increase until population_india surpasses population_china. Once India's population is larger than China's population, we are left with the number of years it takes for India's population to surpass China's population, which is 6 years.

Generally speaking, as one moves from K (Knowledge) to S (Skills) to A (Abilities) to O (Other characteristics), the reliability and validity of measurement are A. Indeterminate, as it depends on which K, S, A, or O is being measured.
Reliability refers to the consistency of a measurement, while validity refers to the accuracy of the assessment in measuring what it is intended to measure. Each KSAO may have different methods of assessment, and their reliability and validity can vary based on the context, the instrument used, and the subject being measured.
For instance, measuring knowledge might involve a standardized test, which can have high reliability and validity. However, assessing skills or abilities may require practical demonstrations, observations, or situational judgment tests, which can be more subjective and have varying levels of reliability and validity. Lastly, evaluating other characteristics, such as personality traits, may involve self-report questionnaires, which can be prone to biases and have different levels of reliability and validity.
In conclusion, the reliability and validity of measurement in KSAOs depend on the specific KSAO being assessed, the context, and the measurement tool employed. Therefore, it is essential to select appropriate assessment methods and ensure their reliability and validity to make accurate and informed decisions about individuals' KSAOs. Therefore, the correct option is A.

Ali's tablet computer has 100 GB of secondary storage. There is currently 80 GB available.
Ali wants to transfer a series of video clips onto his tablet. Each video is, on average, 200 000 kilobytes.
Calculate an estimate of the number of video clips Ali can fit onto his tablet.
Show your working.
Answers
Answer:Ali can fit around 40% of the video clips on his tablet.
Explanation:
To calculate the number of video clips Ali can fit onto his tablet, we need to divide the available storage space by the average size of each video clip.
First, we need to convert the available storage space from gigabytes to kilobytes. We do this by multiplying 80 GB by 1 000 000 (1 GB = 1 000 000 KB).
80 GB x 1 000 000 = 80000000 KB
Next, we need to convert the average video clip size from kilobytes to bytes. We do this by multiplying 200 000 KB by 1 000 (1 KB = 1 000 bytes).
200 000 KB x 1 000 = 200000000 bytes
Now we can divide the available storage space (in bytes) by the average video clip size (in bytes) to find the number of video clips that can fit on the tablet:
80000000 / 200000000 = 0.4 or 40%
So, Ali can fit around 40% of the video clips on his tablet.

Consider a point-to-point link 10 km in length. At what bandwidth would propagation delay (at the speed of 2×108m/s) equal transmit delay for 125-byte packets? What about 640-byte packets?
Answers
Transmission delay = Packet size/ Bandwidth
Propagation delay = Distance/Propagation speed
Propagation speed = 2 × 10^8 m/s
Let's assume that the transmission delay is equal to the propagation delay:
Packet size/Bandwidth = Distance/Propagation speed
Bandwidth = Packet size * Propagation speed / Distance
Bandwidth = 125 * 2 × 10^8 / 10,000 = 2.5 × 10^6 bps or 2.5 Mbps
For 640-byte packets:
Bandwidth = Packet size * Propagation speed / Distance
Bandwidth = 640 * 2 × 10^8 / 10,000 = 12.8 × 10^6 bps or 12.8 Mbps.

Answers
if the wide area network (wan) is supporting converged applications like voice over internet protocol (voip) internet protocol (ip) routing lookups will be even more essential to the assurance of the network.
Understanding WAN
WAN stands for Wide Area Network is a network that is used as a network that connects between local networks. Local computer networks are not only physically adjacent to each other, but share the same group of IP addresses.
The local network can be one room, one office or even one city. While the WAN itself is a network that connects these local networks within a city, province or even between countries. The difference between WAN and LAN networks is in the type of media used. Generally local networks or LANs use similar network media.
While the WAN is connected to devices with different transmission media and protocols. The WAN coverage area is also very wide, but unites the network as if it were in one room. WAN networks have lower data transfer rates than local networks or LANs. WAN network technology relies on companies providing long-distance telecommunications services. WAN networks use many kinds of network technologies with a mix of analog and digital signals for data transmission. Of course this is different from a local network or LAN which uses a connection between computers that are physically connected to each other with the same protocol and transmission media. The components in the WAN and their functions will be discussed later.
