Answer:
-Legitimate sniffers are used for routine examination and problem detection.
-Unauthorized sniffers are used to steal information.
Explanation:
A packet sniffer also known as a packet analyzer, is a computer software or hardware tool that can be used to intercept, log and analyze network traffic and data that passes through a digital network.
Legitimate packet sniffers are used for routine examination and problem detection while Unauthorized packet sniffers are used to steal information.
Packet sniffers serve as network diagnostic tools used by administrators and can be used illicitly to steal network data. They are not easy to detect and don't use viruses to capture data.
Explanation:A packet sniffer can be referred to as a computer software or hardware designed to intercept and log traffic on a digital network. They function as network diagnostic tools used by administrators to troubleshoot and optimize network operations. Legitimate sniffers are indeed used for routine examination and problem detection. On the other hand, unauthorized sniffers are illicitly used to steal information by capturing sensitive data traveling over the network. Unfortunately, contrary to intuition, packet sniffers are not relatively easy to detect because data transmission over networks is typically public. Furthermore, packet sniffers do not use viruses to capture data packets, they simply log the packets moving through networks.

Both classes have no constructors, methods or instance variables. Note: For this exercise, please do not declare your classes using the public visibility modifier.
Answer:
class Day
{
}
class Night
{
}
Explanation:
Given
Two classes named: Day and Night
Requirement: Both classes have no constructors, methods or instance variables. should not be declared using the public visibility modifier.
The syntax to define a class in object oriented programming is
modifier class classname {
// Constructor
constructor(variablename) { ......}
// Methods
methods() { ... }
...
}
Access modifiers (or access specifiers) are keywords in object-oriented languages that set the accessibility of classes, methods, and other members. Examples are private, public, protected, etc.
Going by the syntax above to define class Day
Day
private class Day{
// Constructor
constructor(duration)
{
this.duration = duration;
}
// Methods
CalculateDate() { ... }
}
But the question states that both classes have no constructors, methods or instance variables. should not be declared using the public visibility modifier.
So, class Day will be defined as follows
class Day
{
}
It could also be declared using visibility modifiers other than public modifier. So, class Day will be defined as follows
private class Day
{
}
and
protected class Day
{
}
Similarly, class Night can be defined as follows
class Night
{
}
private class Night
{
}
and
protected class Night

Your application needs to process large numbers of job requests and you need to ensure that they are processed in order, and that each request is processed only once. How would you deploy SQS to achieve this end?
a.Use the SetOrder attribute ensure sequential job processing.
b.Convert your standard queue to a FIFO queue by renaming your standard queue with the .fifo suffix.
c. Use an SQS FIFO queue to process the jobs.
d.Configure FIFO delivery in a standard SQS queue.
Answer:
Use an SQS FIFO queue to process the jobs.
Explanation:
SQS stands for Simple Queue Service. It is a programmatic web service that is used to process and store information between computers. SQS was designed to build applications to prevent requests from staying too long on a queue. They process large number of requests at least once and in a sequential order. SQS removes messages permanently from the queue that have been there for a maximum period of time. The default retention period is usually 240 hours but you can reset it to a time to suit your desire. Using FIFO( First-in, First-out) queue, messages are processed exactly once and it supports 300 messages per second. Therefore, using an SQS FIFO queue to process messages will ensure that messages are processed in order and only once.

What are ways to enter formula in Excel? Check all that apply
Final answer:
To enter formulas in Excel, one can type them directly or use the pointing method. AutoSum is a feature that can create formulas automatically, and keyboard shortcuts like Ctrl + Shift + Enter can apply formulas across multiple cells.
Explanation:
To enter a formula in Excel, you can type the formula directly into the cell by starting with an equal sign (=). This can include cell references, arithmetic operators, and constants. Another way to enter formulas is by using the pointing method, where you click on the cells you want to reference instead of typing them, which can help avoid typing errors. For example, to calculate Owner's Equity, you would type '=', click on cell D30, type '-', and then click on cell D60, followed by clicking the Enter check mark on the formula bar. Additionally, when using functions like AutoSum, Excel can automatically generate a formula. Simply select the destination cell, click the AutoSum button, and adjust the default range if necessary before confirming with the Enter check mark.
Remember that after entering a formula, if you want to apply it to multiple cells, you need to use the Ctrl + Shift + Enter shortcut instead of just hitting Enter to ensure it populates across the selected range. You can also use various keyboard shortcuts to streamline the data entry process in Excel, such as F1 to open the Help pane for more shortcuts.

When the processor needs an instruction or data, it searches memory in this order: L1 cache, then L2 cache, then L3 cache (if it exists), then RAM — with a greater delay in processing for each level it must search.
Answer and Explanation:
Memory Cache speed the processes of the computer. It stores instruction and data. The computer has two types of memory cache
L1 cache, L2 cache, and L3 Cache i.e., Level 1, Level 2 and Level 3
L1 cache is built on the processor chip and has a minimal capacity.
L2 cache is slower than L1 and has a large capacity. Mostly processor uses ATC advanced transfer cache.
When the processor needs instruction, it searched in order L1 cache than L2 cache and L3. If any data or instruction is not found, then search slower speed medium such as a hard disk and optical disc.
Processor checks data or instruction first in the L1 cache, then L2, L3 cache and finally RAM. The time required to access data increases with each level, starting from the least latency in L1 cache to the most latency in RAM. This hierarchy is utilized for maintaining quick instruction execution.
Explanation:The subject of this question is related to a computer processor and its memory hierarchy. In a processor, when an instruction or data is needed, it typically follows a sequential order for searching - first it checks L1 cache, if not found then it checks L2 cache, further the L3 cache and finally the RAM. Each level increases the delay in processing as the time required to access data increases from L1 cache to RAM.
This search order is utilized since the closest memory to the processor (L1 cache) has the least latency, and therefore provides the fastest access to data, while the furthest memory (RAM) has higher latency but typically larger size.
Therefore, by checking the closest memory levels first, the processor can keep instruction execution as rapid as possible.

Explanation:
"two stations communicate via a 1-mbps satellite link with a propagation delay of 279 ms. the satellite serves merely to transmit data received from on station to another, with negligible switching delay. using hdlc frames of 1024 bits with 3-bit sequence numbers, what is the maximum possible data throughput, that is, what is the amount of data bits transferred using hdlc frame per second?"
Answer:
The answer is "[tex]\bold{11964.9 \times 10^3 kbps}[/tex]"
Explanation:
The
[tex]t_{pd} = 279 \ ms[/tex]
[tex]t_{single} = \frac{Bits \ HDLC} {Link \ rate}\\[/tex]
[tex]t_{single} = \frac{1024 }{10^6} \ ms\\[/tex]
Transmit station can controls at most 7 frames in 3 bit sequence and without act total time to transmit.
Total time (t) = time for first frame + 2(frame delays)
[tex]t=\frac{1024}{10^6}+ 279+279\\\\t= 0.571 m[/tex]
during the time t frame sent = 7 So, data on each frame is
frame = frame size - ( flag + address+control+fcs bits +flag hits)
frame = 1024 -(8+8+8+16+8)
frame= 976 bits frame
through put = [tex]\frac{7 \times 976}{0.571 \times 10^{-3}}\\[/tex]
through put = [tex]\frac{6832 \times 1000}{0.571}[/tex] = [tex]11964.9 \times 10^3[/tex] kbps
The maximum data throughput, considering HDLC frames and the satellite link's delay, is approximately 1830 bits per second.
To determine the maximum data throughput over the 1 Mbps satellite link with HDLC frames, we need to consider the propagation delay and the frame size.
1. **Frame Size and Throughput Calculation:**
- HDLC frames have a payload of 1024 bits.
- Including the HDLC overhead (typically 8 bits for flag and sequence numbers), the total frame size is 1032 bits.
2. **Propagation Delay:**
- The propagation delay is 279 ms (milliseconds) or 0.279 seconds.
3. **Maximum Throughput Calculation:**
- First, calculate the time taken to transmit one frame:
[tex]\[ \text{Time to transmit one frame} = \frac{\text{Frame size in bits}}{\text{Link speed in bits per second}} = \frac{1032 \text{ bits}}{1 \text{ Mbps}} = 0.001032 \text{ seconds} \][/tex]
- To find the maximum throughput, we consider the time to transmit one frame and the round-trip propagation delay:
[tex]\[ \text{Maximum throughput} = \frac{\text{Frame size in bits}}{\text{Time to transmit one frame + 2 * Propagation delay}} \][/tex]
[tex]\[ \text{Maximum throughput} = \frac{1024 \text{ bits}}{0.001032 \text{ s} + 2 \times 0.279 \text{ s}} = \frac{1024 \text{ bits}}{0.559 \text{ s}} \approx 1830 \text{ bits/second} \][/tex]
4. **Conclusion:**
- The maximum possible data throughput, considering the HDLC frame size and the propagation delay, is approximately **1830 bits per second**. This represents the effective data transfer rate accounting for the transmission time of frames and the round-trip propagation delay of the satellite link.
Which of the following is an advantage of using an internal database? A. Data always remains current in internal databases. B. Highly sophisticated equipment and techniques are not required for maintaining internal databases. C. Internal databases can be accessed more quickly and cheaply than other information sources. D. Internal databases require less maintenance efforts. E. Information obtained from internal databases is almost always sufficient for making marketing decisions. 2 points
Answer:
The correct answer to the following question will be "Option C".
Explanation:
Internal databases include the digital customer as well as industry details sets collected via sources of information throughout the corporate network.
Marketing executives can quickly or easily access or interact with information throughout the database or repository to define commercial opportunities and challenges, execute projects, as well as quality assessments.The growing field offers a unique viewpoint, but the divisions are linked by the data or information.The other options are not related to the advantages of the internal database. So that Option C is the right answer.
Which of the following loop conditions will read all the data in the file assuming that each line in the file contains two integer values, and you will read the first one into a variable named intOne, and the other into intTwo
Answer:
while(inFile >> intOne >> intTwo)
Explanation:
Options are missing but the line of code that does the illustration in the question is while(inFile >> intOne >> intTwo)
Considering two variables, intOne and intTwo
Suppose that a file location has been specified, the infile statement identifies file which could either be an external data or an in-stream data from which data should be read.
while(inFile >> intOne >> intTwo)
Declares a while loop, with the help of the inFile statement, values in the first column are entered into intOne while the second column are entered into intTwo through with the help of then input channel symbol (>>).
