A broadcast network is one in which a transmission from any one attached station is received by all other attached stations over a shared medium. Examples are a bus-technology local area network, such as Ethernet, and a wireless radio network. Discuss the need or lack of need for a network layer (OSI layer 3) in a broadcast network.
Answer:
In a broadcast network such as radio network for example a walkie talkie, the broadcasted transmission is received equally by all receivers indiscriminately which may lead to dissemination of classified information to an unauthorized receiver, therefore, the network layer is required is needed to ensure proper routing of the information
Similarly, when the all the broadcasters in one location are each trying to send messages to different receivers at another given location, there would be potential for network congestion and it would be difficult to send information through the network
When there is need for priority service the presence of a network layer is needed in the network
However, when the above functions performed by the network layer is not required, then, the network layer can be excluded, such as the communication between layers 4 - 7 of the OSI model
Explanation:
true or false? transmitting private or sensitive data unencrypted is a risk in both the local area network (lan) and wide area network (wan) domains of a typical it infrastructure.
The given statement "Transmitting private or sensitive data unencrypted is a risk in both the Local Area Network (LAN) and Wide Area Network (WAN) domains of a typical it infrastructure" is True because Encryption is essential for protecting sensitive information from unauthorized access, tampering, or theft.
In a LAN, devices are connected within a small geographical area, such as a single building or office. Although the risk of interception may be lower compared to a WAN, unencrypted data can still be accessed by malicious individuals, either through unauthorized physical access to the network or by exploiting vulnerabilities in the network's security measures. Additionally, insiders within the organization, such as employees or contractors, can pose a risk if they access sensitive information without proper authorization.
On the other hand, a WAN connects devices over a much larger geographical area, often spanning across cities or countries. Data transmitted over a WAN is more susceptible to interception, as it passes through various intermediate devices, such as routers and switches, before reaching its destination. The risk of unauthorized access or tampering increases significantly due to the involvement of multiple parties and potential vulnerabilities in the overall network infrastructure.

A bidding system can only accept the next bid price to be higher than the previous one. Which property or properties would not be met regarding the bid price? A. Transitive and symmetric B. Reflexive and anti-symmetric C. Reflexive and symmetric D. Anti-symmetric E. Symmetric
The property or properties that would not be met regarding the bid price in a bidding system that can only accept the next bid price to be higher than the previous one are reflexive and symmetric. option C.
In a bidding system, the bid price must always be higher than the previous one. This means that the bid price cannot be equal to the previous one (reflexive property) and cannot be lower than the previous one (symmetric property).
The reflexive property states that a value is equal to itself (a=a). In a bidding system, the bid price cannot be equal to the previous one, so this property is not met.
The symmetric property states that if a value is related to another value, then the other value is also related to the first value (a=b, then b=a). In a bidding system, the bid price cannot be lower than the previous one, so this property is not met.
Therefore, the correct answer is C. Reflexive and symmetric.

You make a purchase at a local hardware store, but what you've bought is too big to take home in your car. For a small fee, you arrange to have the hardware store deliver your purchase for you. You pay for your purchase, plus the sales taxes, plus the fee. The taxes are 7.5% and the fee is $20. (i) Write a function t(x) for the total, after taxes, on the purchase amount x. Write another function f(x) for the total, including the delivery fee, on the purchase amount x. (ii) Calculate and interpret (f o t)(x) and (t o f )(x). Which results in a lower cost to you
Answer:
\(f(x) = 1.075x\)
\(t(x) = x + 20\)
\((f\ o\ t)(x) = 1.075x + 21.5\)
\((t\ o\ f)(x) = 1.075x + 20\)
Explanation:
Given
\(Tax = 7.5\%\)
\(Fee = \$20\) -- delivery
Solving (a): The function for total cost, after tax.
This is calculated as:
\(f(x) = Tax *(1 + x)\)
Where:
\(x \to\) total purchase
So, we have:
\(f(x) = x * (1 + 7.5\%)\)
\(f(x) = x * (1 + 0.075)\)
\(f(x) = x * 1.075\)
\(f(x) = 1.075x\)
Solving (b): Include the delivery fee
\(t(x) = x + Fee\)
\(t(x) = x + 20\)
Solving (c): (f o t)(x) and (t o f)(x)
\((f\ o\ t)(x) = f(t(x))\)
We have:
\(f(x) = 1.075x\)
So:
\(f(t(x)) = 1.075t(x)\)
This gives:
\(f(t(x)) = 1.075*(x + 20)\)
Expand
\(f(t(x)) = 1.075x + 21.5\)
So:
\((f\ o\ t)(x) = 1.075x + 21.5\)
\((t\ o\ f)(x) = t(f(x))\)
We have:
\(t(x) = x + 20\)
So:
\(t(f(x)) = f(x) + 20\)
This gives:
\(t(f(x)) = 1.075x + 20\)
We have:
\((f\ o\ t)(x) = 1.075x + 21.5\) ---- This represents the function to pay tax on the item and on the delivery
\((t\ o\ f)(x) = 1.075x + 20\) --- This represents the function to pay tax on the item only
The x coefficients in both equations are equal.
So, we compare the constants
\(20 < 21.5\) means that (t o f)(x) has a lower cost
1. Assume Printers and Ink Cartridges are complements, show graphically what must be happening to the demand for Printers if, other things equal, the demand for Ink Cartridges is increasing. How about if the demand for Ink Cartridges is falling? (A complete answer would include explaining what is happening with Perinters, DPrinters, QDerinters, PInk Cartridges, Q Dink Cartridges, D ink Cartridges). 2. Assume Pepsi and Coke are substitutes; show graphically what happens to the demand for Coke if, other things equal, the price of Pepsi falls. How about if the price of Pepsi increases? (A complete answer would include explaining what is happening with Peepsi, DPepsi, QDepsi, PCoke, QDcoke, D Coke).
Graphically, if Printers and Ink Cartridges are complements and the demand for Ink Cartridges is increasing, it implies that the demand for Printers will also increase.
The relationship between the two can be represented by a rightward shift in the demand curve for Printers. This shift indicates an increase in the quantity demanded for Printers at each price level, leading to higher equilibrium prices (PPrinters) and quantities (QDPrinters) for Printers.
Conversely, if the demand for Ink Cartridges is falling, the demand for Printers will also decrease. In this case, the demand curve for Printers will shift leftward, indicating a decrease in the quantity demanded for Printers at each price level. This will result in lower equilibrium prices (PPrinters) and quantities (QDPrinters) for Printers.
To summarize, when Ink Cartridges are complements to Printers, an increase in the demand for Ink Cartridges leads to an increase in the demand for Printers, while a decrease in the demand for Ink Cartridges leads to a decrease in the demand for Printers.
Complementary goods are products that are consumed together, where the demand for one product affects the demand for the other. In this case, Printers and Ink Cartridges are complements, meaning they are typically used together. When the demand for Ink Cartridges increases, it indicates a higher desire or need for printing, which leads to an increased demand for Printers. This relationship can be visualized by a rightward shift in the demand curve for Printers.
The shift in the demand curve for Printers implies that at each price level, consumers are willing to buy more Printers, resulting in a higher equilibrium price (PPrinters) and quantity (QDPrinters) for Printers in the market. This shift occurs because as more people purchase Ink Cartridges, they require Printers to use them effectively, creating a higher demand for Printers.
Conversely, when the demand for Ink Cartridges falls, it suggests a decreased need or desire for printing, which in turn leads to a decrease in the demand for Printers. The demand curve for Printers shifts leftward, indicating that at each price level, consumers are willing to buy fewer Printers. As a result, the equilibrium price (PPrinters) and quantity (QDPrinters) for Printers in the market decrease.
In both cases, the change in demand for Ink Cartridges directly affects the demand for Printers due to their complementary nature. An increase or decrease in the demand for Ink Cartridges leads to a corresponding increase or decrease in the demand for Printers, respectively.

One server, HyperVTest, is going to be used mainly for testing and what-if scenarios, and its data drive is 250 GB. You estimate that you might have 8 or 10 VMs configured on HyperVTest with two or three running at the same time. Each test VM has disk requirements ranging from about 30 GB to 50 GB. The other server, HyperVApp, runs in the data center with production VMs installed. Its data drive is 500 GB. You expect two VMs to run on HyperVApp, each needing about 150 GB to 200 GB of disk space. Both are expected to run fairly disk-intensive applications. Given this environment, describe how you would configure the virtual disks for the VMs on both servers.
The virtual disk configuration for the VMs on both servers in this environment is shown below.

What is Hyper V Test?While there are several methods for testing new virtual machine updates, Hyper-V allows desktop administrators to add multiple virtual machines to a single desktop and run tests. The Hyper-V virtualization technology is included in many versions of Windows 10. Hyper-V allows virtualized computer systems to run on top of a physical host. These virtualized systems can be used and managed in the same way that physical computer systems can, despite the fact that they exist in a virtualized and isolated environment. To monitor the utilization of a processor, memory, interface, physical disk, and other hardware, use Performance Monitor (perfmon) on a Hyper-V host and the appropriate counters. On Windows systems, the perfmon utility is widely used for performance troubleshooting.Therefore,
Configuration:
Creating 5 Virtual disks of 50 GB each.
1 virtual disk of 50 GB is assigned to 2 VM.
The above configuration is because since two or three VM will be running at the same time and using the same virtual disk will cause a problem since the applications are disk intensive, running three VMs with different virtual disks assigned to them, will not cause a problem.
For Hyper V App,
Two VM will run at the same time, and the disk requirement is 150 - 200 GB of 500 GB total disk space.
Configuration:
Creating 2 virtual disks of 200 GB each with dynamic Extension and assigning each one to a single VM will do the trick.
