Hi, I provided some explanation of key terms.
Explanation:
Wireless hacking: basically the term refers to any unethical activity carried over a radio wave-connected network (eg Internet or Wifi connection) that would provide unauthorized access to information.
Hardware hacking: On the other hand, hardware hacking involves resetting physical hardware with the objective of using it in a way not originally intended by the manufacturer.

Calculate the total time required to transfer a 500KB file in the following cases. Assume an RTT of 50ms, a packet size of 2KB, and an initial 2xRTT of handshaking before data is sent. A. If the bandwidth is 2Mbps, what is the Bandwidth-Delay Product (BDP)
Answer:
i) Total time = 2457.73 secs
ii) BDP = 0.01 Mbyte
Explanation:
Packet size : 2 Kb = ( 2 * 8192 ) bits = 16384 bits
Bandwidth : 2Mbps = 2,000,000 bits/sec
RTT = 50 ms = 0.050 secs
i) Determine total time required to transfer 500 kB
= Initial handshake + Time for transmission of all files + propagation delay
= 2 x RTT + Time for transmission + RTT /2
Total time = ( 2 * 0.05 ) + (1500 * 1.6384 )+ ( 0.050 / 2 ) = 2457.73 secs
ii) Determine the Bandwidth-delay product
= data link capacity * RTT
= 2 Mbps * 50 ms = 100,000 = 0.01 MByte
Why use LinkedIn automation for LinkedIn?
Answer:
Using LinkedIn automation tools to run successful outreach campaigns has become popular. It’s because these tools automate tedious networking tasks such as visiting profiles, collecting data, sending out bulk connection requests, messages, and follow-ups, etc.
With the help of the latest LinkedIn automation tools, you can quickly perform all the repetitive tasks while saving yourself a lot of time that you can use on actual relationship building and lead nurturing tasks.
However, LinkedIn isn’t really amused when using any bots or automation tools for LinkedIn.

Explanation:
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))
Answer:
The program in Python is as follows:
current_price = int(input("Current Price: "))
last_price = int(input("Last Month Price: "))
change = current_price - last_price
mortgage = (current_price * 0.051) / 12
print('Change: {:.2f} '.format(change))
print('Mortgage: {:.2f}'.format(mortgage))
Explanation:
This gets input for current price
current_price = int(input("Current Price: "))
This gets input for last month price
last_price = int(input("Last Month Price: "))
This calculates the price change
change = current_price - last_price
This calculates the mortgage
mortgage = (current_price * 0.051) / 12
This prints the calculated change
print('Change: {:.2f} '.format(change))
This prints the calculated monthly mortgage
print('Mortgage: {:.2f}'.format(mortgage))
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='0.\n')

Based on the naming recommendations in the book, which of the following is a good identifier for a variable that will be used to hold an employee’s phone number? a. EmployeePhoneNumber b. emphonumber c. employee_phone_number d. empPhoneNum
Answer:
A good identifier for a variable that will be used to hold an employee’s phone number is:
a. EmployeePhoneNumber
Explanation:
An identifier is a string that uniquely identifies or names the entity or an object. The object or entity may be a constant, variable, structure, function, etc. Identifiers can be formed from uppercase and lowercase letters, digits, and underscores. Meaningful identifiers mostly favor the use of long descriptive names like EmployeePhoneNumber. However, the other options can still be used.

Suppose we can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. We can redeem six coupons for one chocolate bar from the machine. This means that once you have started buying chocolate bars from the machine, you always have some coupons. We would like to know how many chocolate bars can be eaten if we start with N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars after purchasing 6 bars giving us 6 coupons and then redeeming the 6 coupons for one bar. This would leave us with one extra coupon. For 11 dollars, we could consume 13 chocolate bars and still have one coupon left. For 2 dollars, we could have consumed 14 chocolate bars and have two coupons left.Write a program that inputs a value for N and outputs how many chocolate bars we can eat and how many coupons we would have left over. Use a loop that continues to redeem coupons as long as there are enough to get at least one chocolate bar.
Answer and Explanation:
Using JavaScript:
/* program should take N input which represents the dollar amount and output how many chocolate bars and how many coupons we have*/
function chocolatebar(dollars){
var dollaramt= dollars;
var i;
for(i=0; i <= dollaramt; i++){
i=i+6
?
Alert ("you have 1 extra chocolate bar");
:
Alert ("keep buying chocolate bars to get more coupons for a bonus chocolate bar")
}

Cryptarithmetic algorithm
Answer:
CryptArithmetic or verbal arithmetic is a class of mathematical puzzles in which the digits are replaced by letters of the alphabet or other symbols. Usually it is required that each letter would be replaced by a unique digit. Each letter having different value from the other letters.
Explanation:
Cryptarithm now denotes mathematical problems usually calling for addition, subtraction, multiplication, or division and replacement of the digits by letters of the alphabet or some other symbols. ... Since D × B has only one digit, B must be 3 or less. The only two possibilities are 0 and 2.

local area network to the wide area networkmicrocomputer to the internet connectionAssume a TCP sender is continuously sending 1,090-byte segments. If a TCP receiver advertises a window size of 5,718 bytes, and with a link transmission rate 26 Mbps an end-to-end propagation delay of 22.1 ms, what is the utilization
Answer:
for the 5 segments, the utilization is 3.8%
Explanation:
Given the data in the question;
segment size = 1090 bytes
Receiver window size = 5,718 bytes
Link transmission rate or Bandwidth = 26 Mbps = 26 × 10⁶ bps
propagation delay = 22.1 ms
so,
Round trip time = 2 × propagation delay = 2 × 22.1 ms = 44.2 ms
we determine the total segments;
Total segments = Receiver window size / sender segment or segment size
we substitute
Total segments = 5718 bytes / 1090 bytes
Total segments = 5.24587 ≈ 5
Next is the throughput
Throughput = Segment / Round trip
Throughput = 1090 bytes / 44.2 ms
1byte = 8 bits and 1ms = 10⁻³ s
Throughput = ( 1090 × 8 )bits / ( 44.2 × 10⁻³ )s
Throughput = 8720 bits / ( 44.2 × 10⁻³ s )
Throughput = 197.285 × 10³ bps
Now Utilization will be;
Utilization = Throughput / Bandwidth
we substitute
Utilization = ( 197.285 × 10³ bps ) / ( 26 × 10⁶ bps )
Utilization = 0.0076
Utilization is percentage will be ( 0.0076 × 100)% = 0.76%
∴ Over all utilization for the 5 segments will be;
⇒ 5 × 0.76% = 3.8%
Therefore, for the 5 segments, the utilization is 3.8%

why do we need vector graphics for creating logo
Answer:
hope it will help uplease mark brillient
Answer:
So we can maintain high quality designs at any graphic scale.
Explanation:
Unlike other graphic formats which simply define colors for fixed pixels, vector graphics define points and shapes (vectors) which are then used to draw the graphic at the desired and appropriate resolution.
Our graphic can look good at any resolution, no matter how large it gets. If we take a png or jpg file and make it extremely large, you'll notice the image begins to get blurry, because the pixels are being stretched and colors are being predicted or matched for the larger scale.
Chassis intrusion detection is an option that can be enabled/disabled in the BIOS setup utility (if a BIOS comes equipped with this feature).Coupled with a hardware sensor mounted insided the computer case, this functionality can be used to check if the case was opened and display a notification alert during next boot.
a. True
b. False
Answer: True
Explanation:
Chassis intrusion detection is simply a vital security feature which is used typically by large corporate networks. It's simply an intrusion detection method which can be used in alerting a system administrator when there's a situation whereby a person opens a computer case which can then be investigated in order to know if the computer hardware has been tampered with.
It should also be noted that the chassis intrusion detection can then be either enabled or disabled in the BIOS setup utility if a BIOS comes equipped with this feature.
The correct option is True.

Write a function named square_list that takes as a parameter a list of numbers and replaces each value with the square of that value. It should not return anything - it should mutate the original list.
Answer:
The function is as follows:
def square_list(myList):
for i in range(len(myList)):
myList[i] = myList[i]**2
print(myList)
Explanation:
This defines the function
def square_list(myList):
This iterates through the list elements
for i in range(len(myList)):
This squares each list element
myList[i] = myList[i]**2
This prints the mutated list
