Answer:

True I think but I'm not sure

a. With circuit switching, the number of users that can be supported on a 5 Mbps link, with each user requiring 250 kbps and transmitting 10% of the time, can be calculated by dividing the total available bandwidth by the bandwidth required per user.

b. In packet switching, the probability that a given user is transmitting can be calculated by dividing the transmission time of a user by the total time.

c. The probability that at any given time exactly n users are transmitting simultaneously can be calculated using the binomial probability formula.

d. The probability that there are 21 or more users transmitting simultaneously can be calculated using the complement of the probability that fewer than 21 users are transmitting.

a. With circuit switching, the bandwidth is dedicated to each user for the entire duration of their transmission. Each user requires 250 kbps, which is equivalent to 0.25 Mbps. Since each user transmits only 10% of the time, the effective bandwidth required per user is 0.025 Mbps. The number of users that can be supported is obtained by dividing the total available bandwidth of 5 Mbps by the effective bandwidth required per user: 5 Mbps / 0.025 Mbps = 200 users.

b. In packet switching, the probability that a given user is transmitting depends on the ratio of their transmission time to the total time. Since each user transmits only 10% of the time, the probability of a given user transmitting is 10% or 0.1.

c. The probability that exactly n users are transmitting simultaneously can be calculated using the binomial probability formula. For 120 users and a probability of 0.1 for each user transmitting, the probability of exactly n users transmitting simultaneously can be calculated using the formula P(n) = (120 choose n) * (0.1)^n * (0.9)^(120-n).

d. To find the probability that 21 or more users are transmitting simultaneously, we need to calculate the complement of the probability that fewer than 21 users are transmitting. This can be obtained by summing the probabilities of having 0, 1, 2, ..., 20 users transmitting and subtracting the result from 1.

The two main types of communication channels are synchronous and asynchronous.

Synchronous communication refers to a type of communication where all parties involved in the conversation or interaction are present and engaged at the same time, in real-time. During synchronous communication, the sender and receiver of the message are actively exchanging information and responding to each other immediately. Examples of synchronous communication include face-to-face conversations, phone calls, video conferencing, and live chat.

On the other hand, asynchronous communication is a type of communication where the sender and receiver do not need to be present and engaged at the same time. Instead, messages are sent and received at different times, allowing for more flexibility in responding to messages and providing information. Examples of asynchronous communication include email, voicemail, text messaging, and social media posts.

An Active Directory Domain Services (AD DS) tree consists of multiple domains connected by transitive trusts. Transitive trusts automatically flow across the domain, but it requires a domain trust to be in place. Transitive trusts can be one-way, two-way, zero or infinite loops.

One-way trust allows access to the trusted domain, but not the other way around. Two-way trust is bidirectional, meaning both the domains are trusted. Zero trust is implemented when there is no trust between the two domains. In an infinite loop, a trust relationship occurs that returns to the original domain without the need for the next domain.

These roles are assigned to a single domain controller in a domain and are responsible for managing domain updates, user accounts, and other operations.The Schema Master is responsible for changes in the schema, and it can only exist in one domain per forest.

In a search network campaign, conversions typically refer to actions taken by users immediately after clicking on an ad and visiting the advertiser's website.

These actions can include completing a purchase, filling out a form, or any other desired outcome defined as a conversion.

On the other hand, view-through conversions are specific to display network campaigns. They occur when a user sees an ad but does not click on it, and later converts by taking the desired action. View-through conversions are attributed to the display ad even though there was no click involved.

If a search network campaign shows conversions but no view-through conversions, it implies that users are primarily converting through immediate actions after clicking on the ads rather than through later conversions after viewing but not clicking on the ads. This can be influenced by the nature of search network campaigns, where users actively search for specific products or services and are more likely to engage immediately upon clicking on relevant ads.

The absence of view-through conversions in a search network campaign could indicate that users have a high intent to convert and are more likely to do so directly after clicking, rather than relying on future conversions from ad impressions. It's important to note that view-through conversions are more relevant for display network campaigns where users are exposed to ads but may not necessarily click on them.

The sorted array for the first 5 values in the given set of values would be: [157, 346, 31, 22, 212].

Here are the steps required to perform a heap sort on the first 5 values of the given set of values:

Create a max heap from the first 5 values (346, 22, 31, 212, 157). This can be done by starting at the index of the last non-leaf node and performing a max heapify operation on each parent node in reverse level order:

Initial array: [346, 22, 31, 212, 157]

Max heap:       [346, 212, 31, 22, 157]

Swap the root node (the maximum value) with the last leaf node (157) and remove it from the heap:

Max heap:       [157, 212, 31, 22, 346]

Perform another max heapify operation on the root node to restore the max heap property:

Max heap:       [212, 157, 31, 22, 346]

Swap the root node with the last remaining leaf node (346) and remove it from the heap:

Max heap:       [346, 157, 31, 22]

Perform another max heapify operation on the root node to restore the max heap property:

Max heap:      [346, 157, 31, 22]

Swap the root node with the last remaining leaf node (22) and remove it from the heap:

Max heap:       [22, 157, 31]

Perform another max heapify operation on the root node to restore the max heap property:

Max heap:       [157, 22, 31]

Swap the root node with the last remaining leaf node (31) and remove it from the heap:

Max heap:       [31, 22]

Perform another max heapify operation on the root node to restore the max heap property:

Max heap:       [31, 22]

The final sorted array is created by taking each removed element and adding them to a new array in reverse order of removal:

Sorted array:   [157, 346, 31, 22, 212]

Therefore, the sorted array for the first 5 values in the given set of values would be: [157, 346, 31, 22, 212].

RAID 0 is a process of organizing data on two or more disks to enhance speed and increase storage space. This is accomplished by spreading data across various hard drives, hence speeding up the performance of read/write operations.

However, unlike other types of RAID that provide data redundancy and fault tolerance, RAID 0 does not protect against disk failure, and it does not have a backup system. It does not duplicate your data and save it on two identical drives as claimed in the question.RAID 0 functions by dividing data across various hard drives, allowing for faster access to files and higher I/O (Input/Output) performance. Because files are split between several disks, read and write operations can occur simultaneously on each disk, resulting in improved system performance.

Since it does not provide data redundancy, RAID 0 can be dangerous because if one of the disks fails, all of the data on both disks can be lost. In other words, if one disk fails, the entire array fails. In summary, RAID 0 is a technique for combining storage space and increasing the speed of read/write operations on a computer. It does not duplicate your data and save it on two identical drives as claimed in the question.

Arguments passed to a function in the same order that the function's parameters are listed are called positional arguments. In Python, when a function is called, the arguments passed to the function are bound to the function parameters in the order they are defined.

So, if a function has two parameters, the first argument will be bound to the first parameter, and the second argument will be bound to the second parameter. This is known as positional arguments or position-based arguments.

For example, consider the following function:def greet(name, greeting):print(greeting, name)If we call the greet function like this:greet('Alice', 'Hello')Then, 'Alice' is the first argument and 'Hello' is the second argument. The first argument will be bound to the 'name' parameter and the second argument will be bound to the 'greeting' parameter. Therefore, the output will be 'Hello Alice'. However, if we swap the order of the arguments, like this:greet('Hello', 'Alice')Then, 'Hello' will be the first argument and 'Alice' will be the second argument. The first argument will be bound to the 'name' parameter and the second argument will be bound to the 'greeting' parameter. Therefore, the output will be 'Alice Hello'.

The identifier acts as a reference to the memory location where the data value is stored. By using variables, programmers can store and retrieve data, perform calculations, and modify values throughout the execution of a program.

When a variable is declared, memory is allocated to hold its data value based on the variable's data type. The data stored in a variable can be of various types, such as integers, floating-point numbers, characters, or even complex data structures like arrays or objects. The value of a variable can be updated or modified during program execution, allowing for dynamic and flexible behavior.

Overall, variables are essential elements in programming languages as they provide a means to store and manipulate data in memory through an identifier or name. They enable programmers to work with data values and perform computations, making programs adaptable and capable of handling complex tasks.

Secondary data refers to the data that has already been collected by someone else. Primary data, on the other hand, is the data that is collected by the researcher specifically for the research purposes.

Secondary data is different from primary data in many ways. One of the significant characteristics of secondary data is that it is already available, and the researcher does not have to collect it on their own. Secondary data is often easy to obtain, cost-effective, and quick to analyze. It can be derived from various sources such as governmental, non-governmental organizations, commercial, or research institutions.    

Three sources of secondary data include internal sources, external sources, and online sources.    Internal sources: Internal sources are available within the organization. They include administrative records, sales reports, and financial records, among others. Internal sources of data are reliable, and the researcher can trust the accuracy of the information.     External sources: External sources of data come from external sources such as research studies, journals, publications, and books, among others.

They can be accessed by researchers from libraries or archives. They provide a wealth of information that can be used in research studies.    Online sources: Online sources include websites, online databases, and electronic journals, among others. The internet has made it possible for researchers to access various sources of secondary data. They can download information that is relevant to their research study, and this saves time and effort.
