Explanation:
it acts as a barrier between a trusted system or network and outside connections, such as the Internet. However, a computer firewall is more of a filter than a wall, allowing trusted data to flow through it. ... For example, a basic firewall may allow traffic from all IP.

Answer:
hope this helps
Explanation:
Firewalls are software or hardware that work as a filtration system for the data attempting to enter your computer or network. Firewalls scan packets for malicious code or attack vectors that have already been identified as established threats.And also firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules.
A sinewave has a period (duration of one cycle) of 645 μs. What is the corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures?
please help me figure this out I am so confused
The corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures is: 155 kHz.
Given the following data:
Period = 645 μsNote: μs represents microseconds.
Conversion:
1 μs = [tex]1[/tex] × [tex]10^{-6}[/tex] seconds
645 μs = [tex]645[/tex] × [tex]10^{-6}[/tex] seconds
To find corresponding frequency of this sinewave, in kHz;
Mathematically, the frequency of a waveform is calculated by using the formula;
[tex]Frequency = \frac{1}{Period}[/tex]
Substituting the value into the formula, we have;
[tex]Frequency = \frac{1}{645\; * \;10^{-6}}[/tex]
Frequency = 1550.39 Hz
Next, we would convert the value of frequency in hertz (Hz) to Kilohertz (kHz);
Conversion:
1 hertz = 0.001 kilohertz
1550.3876 hertz = X kilohertz
Cross-multiplying, we have;
X = [tex]0.001[/tex] × [tex]1550.39[/tex]
X = 155039 kHz
To 3 significant figures;
Frequency = 155 kHz

Create a Python dictionary that returns a list of values for each key. The key can be whatever type you want.
Design the dictionary so that it could be useful for something meaningful to you. Create at least three different items in it. Invent the dictionary yourself. Do not copy the design or items from some other source.
Next consider the invert_dict function.
def invert_dict(d):
inverse = dict()
for key in d:
val = d[key]
if val not in inverse:
inverse[val] = [key]
else:
inverse[val].append(key)
return inverse
Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the inverted dictionary.
Run your modified invert_dict function on your dictionary. Print the original dictionary and the inverted one.
Describe what is useful about your dictionary. Then describe whether the inverted dictionary is useful or meaningful, and why.

Discuss the scaled index addressing mode and comments on the following instructions?

b) MOV [DX5*DI+30H], CX
For option a:
The baseline register is [tex]\bold{BX}[/tex], while the index register is [tex]\bold{CX+5*AX}[/tex].
The multiplier for Accumulator [tex]\bold{AX }[/tex] will be 5.[tex]\bold{CX }[/tex] will be multiplied with this value.[tex]\bold{CX+5*AX}[/tex] will contain a memory address.The value at position [tex]\bold{CX+5*AX}[/tex] is accessed by [tex]\bold{[{CX+5*AX} ]}[/tex].The value retrieved from the address [tex][\bold{CX+5*AX}][/tex] is moved into Base register BX by the MOV instruction.For option b:
Its index register is [tex]\bold{CX }[/tex], whereas the base register is [tex]\bold{DX5*DI+30H}[/tex].
[tex]\bold{CX}[/tex] has a number, that is copied to a computed place below.After multiplying [tex]\bold{DI}[/tex] by [tex]\bold{5, DX}[/tex] will be multiplied by this [tex]\bold{5*DI}[/tex].To the aforementioned multiplied value,[tex]\bold{ 30H}[/tex] will be added.[tex]\bold{[DX5*DI+30H]}[/tex] is a value located at location [tex]\bold{DX5*DI+30H}[/tex]. [tex]\bold{DX5*DI+30H }[/tex] is a memory address number.As a result, the value of [tex]\bold{CX}[/tex] will be copied to the [tex]\bold{ [DX5*DI+30H] }[/tex]location.Learn more:
