Answer:
16 subnets and 14 hosts assignable IP addresses.
Explanation:
Computer networking is the interconnection and intercommunication of computer devices. These computer devices can be connected using cables or wirelessly. All devices in a network must have an IP address.
Subnetting a network is a process of preventing the waste of IP addresses for the purpose of security and cost. IP4 addresses are 32 bits in size (4 octets) and the host and subnet size is dependant on the host and network bit configuration.
The IP address 200.245.10.150/28 is a class A network address but subnetted to borrow four bits from the fourth octet to produce 16 subnets (2 ^ 4 bits borrowed) and 14 host IP addresses (2^ 4 bits remaining in the fourth octet - 2, which is the network and broadcast addresses).

Answer:
c. legacy systems
Explanation:
A new system might have to interface with one or more legacy systems, which are older systems that use outdated technology.
This ultimately implies that, when a new computer system is to replace an older generation system known as legacy systems, it is important to synchronize.
The conversion depends on the temperature and other factors, but an approximation is that 1inch of rain is equivalent to 6.5inches of snow. Write a script that prompts the user for the number of inches of rain, calls a function to return the equivalent amount of snow, and prints this result. Write the function, as well. Do this two ways: in a separate code file and as a local function.
Answer:
rainInches = int(input("Enter rainfall in inches: "))
def rain_snow_convert( rain):
snow_size = rain * 6.5
return snw_size
snowInches = rain_snow_convert( rainInches)
print(snowInches)
Explanation:
The python source code above return the equivalent size of rainfall to snowfall in inches. There are two ways to write this, one is like on a single file as the code above, the second way is defining the function "rain_snow_convert" in another python file, then importing and calling the function in the input file.
from functionsfile import rain_snow_convert
rainInches = int(input("Enter rainfall in inches: "))
snowInches = rain_snow_convert( rainInches)
print(snowInches)
where "functionfiles" (actually with the extension .py) is the name of the python file with the rain_snow_convert function.

g write a recursive function that prints out all the even numbers between x and y inclusive if x is odd then the print out will start at x 1
Answer:
The function written in python is as follows:
def EvenNumbers(x, y):
if (y < x):
return
if (y % 2 == 0):
EvenNumbers(x, y - 2)
else:
EvenNumbers(x, y - 1)
if (y % 2 == 0):
print(y)
Explanation:
x represents the lower limit while y represents the upper limit.
So, the recursion will be repeated as long as x <= y
This defines the function
def EvenNumbers(x, y):
This checks if y < x. If yes, the recursion stops execution and return to the main
if (y < x):
return
The following if and else condition checks determines the appropriate range of the recursion.
if (y % 2 == 0):
EvenNumbers(x, y - 2)
else:
EvenNumbers(x, y - 1)
The above takes care of printing starting at x + 1 if x is odd
This checks and prints the even numbers in the range
if (y % 2 == 0):
print(y)
To call the function from main, make use of
EvenNumbers(x, y)
Where x and y are integers
e.g EvenNumbers(2,10), EvenNumbers(1,17), EvenNumbers(3,21)

You and your brother are sharing a printer. You install the driver software onto your computer and install the printer. Then, you disconnect the printer and lend it to your brother. When you reconnect the printer later on, what is most likely to happen?
If the drivers for the printer aren't installed on your brother's computer, then the printer will not work. Everything attached to a computer needs a driver, including the internals, like the graphics card (through the desktop) and the RAM (through the BIOS). When you reconnect it to your computer, it will work because I am assuming that you have the latest drivers installed. However, if you try to plug in the printer to your computer without the proper drivers, then it will NOT work.

Answer:
If this is Amplify, the answer is C which is Air parcel 1 will lose energy to the surrounding air, which will cause more water vapor to fall as rain.
Explanation:
If this is amplifying, then the correct response is C, meaning that Air parcel 1 will lose energy to the surrounding air, increasing the amount of water vapor that rains.
What is an Amplifier?A sign's power can be increased using an electronic device known as an amplifier, electronic amplifier, or amp.
Named after French physicist André-Marie Ampère, the term "ampère" first appeared in 1881 to describe "the current that one volt can transmit through a resistance of one ohm" (1775-1836). adopted in 1881 at the Electric Congress in Paris. reduced form. amplifier (n.)
The triode vacuum tube, developed by Lee De Forest in 1906, was the first widely used device that could amplify, and it led to the creation of the first amplifier in 1912. Up until the 1960s and 1970s, practically all amplifiers employed vacuum tubes until being replaced by transistors.
The technique of increasing the amplitude of an electromagnetic light wave is known as light amplification. The three main categories of this procedure are laser, parametric, and scattering.
In order to reduce the risk of electrocution, the amplifier ground is the ground wire that safely offers the least possible electrical resistance to earth ground or chassis ground. Usually, power mains outlet connections, power supply, or the car chassis are used to ground amps.

a file named loan.html, write an HTML document that looks similar to figure 9-7 in the textbook. Write four functions with these headers:
function doPayment ( )
function doBalance ( )
function computePayment (principal, annualRate, years, periodsPerYear)
function computeBalance (principal, annualRate, years, periodsPerYear, numberOfPaymentPaidToDate)
The first two functions (doPayment and doBalance) do the following:
Take no parameters.
Are called from an onclick attribute.
Get input from the user.
Call the computePayment or the computeBalance function.
Display a result to the user.
The computePayment function computes and returns the monthly payment for a loan with a fixed annual interest rate. The formula for computing a loan payment is
p = ar
1 − (1 + r)−n
Where p is the payment per period, a is the loan amount, r is the interest rate per period, and n is the total number of periods throughout the life of the loan.
The computeBalance function computes and returns the balance for a loan with a fixed annual interest rate. The formula for computing the balance of a loan after d payments have been made is
b = a (1 + r)d − p ( (1 + r)d − 1 )
r
Where b is the balance or payoff amount, a is the loan amount, r is the interest rate per period, p is the payment per period, and d is the number of payments paid to date.
Answer:
function computePayment(principal, annualRate, periodsPerYear){
var pay;
pay = (principal * annualRate)/(1-(1+annualRate)-periodsPerYear);
return pay;
}
function computeBalance(principal, annualRate, periodsPerYear, numberOfPaymentsPaidToDate){
var balance ;
let num = (principal*(1+annualRate)*periodsPerYear);
let denum = numberOfPaymentsPaidToDate *((1+annualRate) * periodsPerYear-1)*annualRate;
balance = num-denum;
return balance;
}
function doPayment(){
let loanAmount = document.getElementById("principal").value;
let rate = document.getElementById("rate").value;
let duration = document.getElementsById("time").value;
let result = computePayment(loanAmount, rate, duration);
document.getElementsById("periodPay").value = result;
}
function doBalance(){
let loanAmount = document.getElementById("principal").value;
let rate = document.getElementById("rate").value;
let duration = document.getElementById("time").value;
let currentPaid = document.getElementById("paidMonths").value;
let result = computeBalance(loanAmount, rate, duration, currentPaid);
document.getElementById("displayBalance").value = result;
}
Explanation:
The javascript source code defines four functions. The 'doPayment' and 'doBalance' functions are initiated with the onclick properties of the HTML file buttons of the loan calculator. The doPayment function gets the user input from the HTML file and assigns them to variable which are used as the parameters of the computePayment function called.
The doBalance function also retrieve user input from the HTML file and calls the computeBalance function to calculate and return the balance of the loan to be paid.

The client provides various information to the server in the first step of the 3-way handshake. a) What is the client's advertised (receive) window size
Answer:
The window size can only be 2-bytes long
Explanation:
TCP three-way handshake is used to establish a connection between a client and a server, giving both the ability to initiate, negotiate, and to separate TCP socket connection ( terminate the connection).
The client sends a SYN message to the server. The server receives the message and sends a SYN-ACK message to the client and the client also responses with an ACK message to establish the connection.
The window size is the size of the packet that can be sent across connections and can only be only 2- bytes long (that is, 65,535 bits).

Write a function that computes that statistic. It should take as its argument an array of waiting times and return the variance of them. Call the function var_based_estimator.
Answer:
Written in Python:
def var_based_estimator(waitingtimes):
isum = 0
for i in range(0,len(waitingtimes)):
isum = isum + waitingtimes[i]
mean = isum/len(waitingtimes)
varsum=0
for i in range(0,len(waitingtimes)):
varsum = varsum + (waitingtimes[i] - mean)**2
variance = varsum/len(waitingtimes)
print(round(variance,3))
Explanation:
(1) To calculate variance, first we need to determine the mean,
(2) Then we subtract the mean from individual data
(3) Then we take the squares of (2)
(4) Sum the results in (3)
(5) Divide the result in (4) by the mean
This is implemented in python as follows:
This line defines the function
def var_based_estimator(waitingtimes):
We start by calculating the mean, here i.e. (1)
This line initializes the sum of all data to 0
isum = 0
The following iteration adds up the elements of waitingtimes list
for i in range(0,len(waitingtimes)):
isum = isum + waitingtimes[i]
The mean is calculated here; [tex]Mean = \frac{\sum x}{n}[/tex]
mean = isum/len(waitingtimes)
(2), (3) and (4) are implemented in the following iteration
First the sum is initialized to 0
varsum=0
This iterates through the list; subtracts each element from the mean; take the square and sum the results together
for i in range(0,len(waitingtimes)):
varsum = varsum + (waitingtimes[i] - mean)**2
This calculates the variance by dividing the (4) by the mean
variance = varsum/len(waitingtimes)
This prints the variance rounded to three decimal placed
print(round(variance,3))
