Answer 1

Note that the principal disadvantage (s) with the waterfall development methodology is (are) "All the Above" (Option D).

What is the Waterfall Development Methodology?

The Waterfall Development Methodology is a process for creating software that involves a series of steps that are followed in a specific order. It is called the "waterfall" method because each step flows into the next, like water flowing down a waterfall.

The first step in the Waterfall Development Methodology is to gather requirements, which means figuring out what the software should do. Next, a design is created, which outlines how the software will look and work. Then, the software is actually developed, which means writing the code and creating the software. After that, the software is tested to make sure it works correctly and any problems are fixed. Finally, the software is deployed, which means it is made available for people to use.

What is an array?

Using an entire set of values at once is possible with array programming, a technique used in computer science. These answers are frequently applied in scientific and engineering contexts. A data structure called an array consists of a set of elements (values or variables), each of which is identified by an array index or key.

Depending on the language, other data types that describe aggregates of values, like lists and strings, may overlap (or be identified with) array types. An array is a grouping of identically-typed elements that are stored in consecutive memory locations and can each be individually referred to using an index to a special identifier.

Based on the information, it should be noted that none of the code will return the same result as all the codes does not assign correct values to array.

Therefore, based on the information, the correct option is E.

Answers

The value of the mean absolute percent error (mape)

What is mean?

Mean is an average value calculated by adding a set of numbers and then dividing by the number of items in the set. It is a measure of central tendency in a set of data and is often used to describe the overall trend or pattern in the data. Mean can also be used to compare sets of data and is often used to compare the performance of different groups of people or businesses.

The mean absolute percent error (MAPE) is a measure of the accuracy of a forecast. It is calculated by taking the mean of the absolute percent errors (the difference between the forecast and the actual value), divided by the mean of the actual values.

For the given data, the MAPE is calculated as follows:

MAPE = (|18.00 - 17| + |20.00 - 25| + |15.00 - 14| + |14.00 - 23|)/(17 + 25 + 14 + 23) = 0.30

Therefore, the mean absolute percent error (MAPE) for the given data is 0.30.

Answers

Yes, the static route for 192.168.2.0 is incorrectly configured.

What is a static route?

Static routing is a routing method that requires manual configuration. The majority of network managers follow static routing. In areas with consistent network and environmental characteristics, this routing will be heavily used.

Static routing is fixed and unaffected by network changes, in contrast to dynamic routing. It is used on a router to increase routing effectiveness and to act as a fallback in case other data cannot be shared.

It takes advantage of the routes that connect the two routes, which are not immediately updatable. As a result, whenever the network changes, static routes must be manually reconfigured. Compared to dynamic maps, it takes little bandwidth. It can be applied to situations where network traffic is planned and predictable.

Air at standard conditions flows steadily at low speed through a horizontal nozzle, discharging to atmosphere, where the pressure is Patm, meaning P2 = Patm. Inlet and exit areas of the nozzle are A1 = 0.10 m2 and A2 = 0.02 m2 , respectively.
Calculate the pressure required at the nozzle inlet, meaning P1, to yield an exit speed of 50 m/s.

Answers

Using  Bernoulli equation we can say that the pressure required at the nozzle inlet, meaning P1, to yield an exit speed of 50 m/s is 1.48 kPa.

How do we calculate the pressure required at the nozzle inlet using Bernoulli equation?

equations that control:

[tex]\frac{p_{1}}{\rho}+\frac{V_{1}^{2}}{2}+g z_{1}=\frac{p_{2}}{\rho}+\frac{V_{2}^{2}}{2}+g z_{2}[/tex]

Continuity for incompressible and uniform flow:

[tex]\sum_{\mathrm{CS}} \vec{V} \cdot \vec{A}=0[/tex]

We know that  

1)   Steady flow.

(2) Incompressible flow.

(3) Frictionless flow.

(4) Flow along a streamline.

(5)[tex]z_{1}=z_{2}[/tex]

(6) Uniform flow at sections (1) and (2).

The maximum speed of 50 m/s is well below 100 m/s, which corresponds to Mach number M≈0.3 in standard air. Hence, the flow may be treated as incompressible.

Apply the Bernoulli equation along a streamline between points (1) and (2) to evaluate [tex]p_{1}[/tex]

p1 − patm = p1 − p2 = ρ/2  (V2^2 −V1^2)

-ρV₁A₁ + ρV₂A₂ = 0 or V₁A₁ =  V₂A₂

V₁ = V₂A₂/A₁ = 50 x 0.02/0.10 = 10 m/s

Since air at standard condition , ρ = 1.23 kg/m³

p1 − patm = ρ/2. (V₂²^2−V₁^²)

= 1/2 × 1.23 x (50² −10²)

= 1.48kPa

The main memory can hold a total of (256 * 1024 * 1024) / 32 = 8,388,608 blocks.

What are main and cache memory?

he main memory in this system has a size of 256 megabytes, which is equal to 256 * 1024 * 1024 bytes. With blocks of 32 bytes in size, this means that the main memory can hold a total of (256 * 1024 * 1024) / 32 = 8,388,608 blocks.

The cache memory, on the other hand, can hold up to 64 blocks. This means that it can store a small fraction of the data that is stored in the main memory. In order to access data that is not stored in the cache, the system must fetch it from the main memory, which takes longer than accessing data directly from the cache.

Five telemetry signals, each of bandwidth 240 Hz, are to be transmitted simultaneously by binary PCM. The signals must be sampled at least 20% above the Nyquist rate. Framing and synchronizing requires an additional 0.5% extra bits. A PCM encoder is used to convert these signals before they are time-multiplexed into a single data stream. Determine the minimum possible data rate (bits per second) that must be transmitted, and the minimum bandwidth required to transmit the multiplex signal.

Answers

To determine the minimum data rate and minimum bandwidth required to transmit the multiplex signal, we need to first determine the minimum sampling rate required to sample each of the telemetry signals. The Nyquist rate is defined as half the bandwidth of the signal, so the Nyquist rate for each telemetry signal is 120 Hz. To sample at least 20% above the Nyquist rate, we need to sample at a rate of at least 120 Hz * 1.2 = 144 Hz.

Since there are 5 telemetry signals, the total number of samples per second is 5 * 144 = 720 samples/s. Since the signals are being encoded using binary PCM, each sample will require 1 bit to represent it. This means that the minimum data rate required to transmit the multiplex signal is 720 samples/s * 1 bit/sample = 720 bits/s.

To determine the minimum bandwidth required to transmit the multiplex signal, we need to consider the bandwidth required for the 5 telemetry signals as well as the additional bandwidth required for framing and synchronization. The total bandwidth required for the telemetry signals is 5 * 240 Hz = 1200 Hz. The additional bandwidth required for framing and synchronization is 1200 Hz * 0.5% = 6 Hz. The total minimum bandwidth required to transmit the multiplex signal is 1200 Hz + 6 Hz = 1206 Hz.

The total amount of samples per second is 5 * 144, or 720 samples/s, because there are 5 telemetry signals.The telemetry signals' overall bandwidth need is 5 * 240 Hz, or 1200 Hz. A further bandwidth of 1200 Hz * 0.5% = 6 Hz is needed for framing and synchronization. 1200 Hz + 6 Hz = 1206 Hz is the total minimum bandwidth needed to carry the multiplex signal.

What is bandwidth?

The maximum pace of data flow along a particular path is referred to as bandwidth in computing. Network bandwidth, data bandwidth, and digital bandwidth are three different types of bandwidth.

Contrary to this definition, bandwidth is used to refer to analog signal bandwidth measured in hertz, which is the frequency range between the lowest and highest attainable frequency while meeting a well-defined impairment level in signal power in the fields of signal processing, wireless communications, modem data transmission, digital communications, and electronics.

The actual bit rate that may be obtained is influenced by the channel noise as well as the signal bandwidth.
