Answer:
xyz = 25
result = square(xyz)
print(result)
The above code assigns the value 25 to variable xyz as 5*5=25. Then next statement is a function call to square() function passing xyz to this function in order to compute the square of 25. The output is:
625
Explanation:
The above code can also be written as:
xyz = 5*5
result = square(xyz)
print(result)
The difference is that xyz is assiged 5*5 which is equal to 25 so the output produced will be the same i.e. 625.
The result variable is used to store the value of square of 25 after the square() method computes and returns the square of 25. So print(result) prints the resultant value stored in the result variable i.e. 625
You are in a library to gather information from secondary sources, and you want to find a current print resource that can supplement information from a book. What source should you use
Answer:
Periodical Literature
Explanation:
In this specific scenario, the best source for you to use would be the periodicals. Periodical Literature is a category of serial publications that get released as a new edition on a regular schedule, such as a magazine, newsletters, academic journals, and yearbooks. Some real-life examples include Sports Illustrated, Discovery, or even Time Magazine. These periodical literary sources all provide up to date data on any topic that is needed.
How would you represent a single cyan-colored pixel in Base64 encoding? (Hint: first think about how to represent cyan as a three-byte binary number, and then do the Base64 encoding from the lecture.)
Answer:
The answer is "AP//"
Explanation:
In the given question choices were missing so, the correct choice can be defined as follows:
The 3-bit color description of 'CYAN' is 011 if we convert it into 3- byte binary representation, we get, the 3- byte binary representation that is equal to 011 = 00000000 11111111 11111111 and to split the 3-byte description into 6-bit subset to transform into Base64. so, we get: 000000 001111 111111 111111
if we have the Base64 alphabet table to convert the 6-bit representation towards its comparable letter or character by the 6-bit subgroup, that can be defined as follows:
In 000000 the decimal value is = 0, which is equal to Base64 character is ='A' . In 001111 the decimal value is = 15, which is equal to Base64 character is= 'P' The 111111, its decimal value is = 63, in the Base64 its character is = '/' The 111111, its decimal value is = 63, in the Base64 its character is = '/'differentiate between web site and web application?

The description including its scenario is listed throughout the explanation section below.
Explanation:
Star topology seems to be a LAN system under which all points are connected to a single cable link location, such as with a switch as well as a hub. Put it another way, Star topology is among the most commonly used network configurations.
Throughout this configuration or setup:
Each common network setups network unit, such as a firewall, switch, as well as computer. The main network computer serves as either a server as well as the peripheral system serves as just a client.ICMP
(a) is required to solve the NAT traversal problem
(b) is used in Traceroute
(c) has a new version for IPv6
(d) is used by Ping
Answer:
(b) is used in Traceroute
(d) is used by Ping
Explanation:
ICMP is the short form of Internet Control Message Protocol. It is a protocol used by networking devices such as routers to perform network diagnostics and management. Since it is a messaging protocol, it is used for sending network error messages and operations information. A typical message could be;
i. Requested service is not available
ii. Host could not be reached
ICMP does not use ports. Rather it uses types and codes. Some of the most common types are echo request and echo reply.
Traceroute - which is a diagnostic tool - uses some messages available in ICMP (such as Time Exceeded) to trace a network route.
Ping - which is an administrative tool for identifying whether a host is reachable or not - also uses ICMP. The ping sends ICMP echo request packets to the host and then waits for an ICMP echo reply from the host.
ICMP is not required to solve NAT traversal problem neither does it have a new version in IPV6.

SONET is the standard describing optical signals over SMF, while SDH is the standard that describes optical signals over MMF fiber.
A. True
B. False
Answer:
False.
Explanation:
SONET is an acronym for synchronous optical networking while SDH is an acronym for synchronous digital hierarchy. They are both standard protocols used for the transmission of multiple digital bit streams (multiplex) synchronously through an optical fiber by using lasers.
Hence, both SONET and SDH are interoperable and typically the same standard protocols in telecommunication networks. Also, the SONET is a standardized protocol that is being used in the United States of America and Canada while SDH is an international standard protocols used in countries such as Japan, UK, Germany, Belgium etc.
The synchronous optical networking was developed in 1985 by Bellcore and it was standardized by the American National Standards Institute (ANSI). SDH was developed as a replacement for the plesiochronous digital hierarchy (PDH).
Generally, SONET comprises of four functional layers and these are;
1. Path layer
2. Line layer.
3. Section layer.
4. Physical or Photonic layer.
The SDH comprises of four synchronous transport modules and these are;
1. STM-1: having a basic data rate of 155.52Mbps.
2. STM-4: having a basic data rate of 622.08Mbps.
3. STM-16: having a basic data rate of 2488.32Mbps.
4. STM-64: it has a basic data rate of 9953.28Mbps.
These two standard telecommunications protocols are used to transmit large amounts of network data over a wide range through the use of an optical fiber.

The user can set their own computer hostname and username. Which stage of the hardware lifecycle does this scenario belong to?
Answer:
Deployment
Explanation:
Hardware lifecycle management is geared at making optimum use of the computer hardware so as to maximize all the possible benefits. During the deployment stage of the hardware lifecycle, the user is prompted by the computer to input their own computer hostname and username. In doing this, it is important that the user takes note of possible flaws in security. Passwords are set at this stage too. The four stages in the hardware lifecycle are procurement, deployment, maintenance, and retirement. At the deployment stage, the hardware is set up and allocated to employees so that they can discharge their duties effectively.
So, for organizations, it is important that strong passwords are used to prevent security breaches in the event that an employee leaves the organization.

Write, compile and test (show your test runs!) program that calculates and returns the fourth root of the number 81, which is 3. Your program should make use of the sqrt() method. Math.sqrt(number).
Answer:
I am writing a JAVA program. Let me know if you want the program in some other programming language.
public class FourthRoot{ //class to calculate fourth root of 81
public static void main(String[] args) { //start of main() function body
double square_root; //declares to hold the fourth root of 81
double number=81; // number is assigned the value 81
/* calculates the fourth root of number using sqrt() method twice which means sqrt() of sqrt(). This is equivalent to pow(number,(0.25)) where pow is power function that computes the fourth root by raising the number 81 to the power of 0.25 which is 1/4 */
square_root=Math.sqrt(Math.sqrt(number));
//displays the fourth root of 81 i.e. 3
System.out.println("Fourth Root of 81 is "+ square_root); } }
Explanation:
The program is well explained in the comments given along with each statement of the program . Since it was the requirement of the program to user Math.sqrt() method so the fourth root of number= 81 is computed by taking the sqrt() of 81 twice which results in the fourth root of 81 which is 3.
So the first sqrt(81) is 9 and then the sqrt() of the result is taken again to get the fourth root of 81. So sqrt(9) gives 3. So the result of these two computations is stored in square_root variable and the last print statement displays this value of square_root i.e. the fourth root of number=81 which is 3.
Another way to implement the program is to first take sqrt(81) and store the result in a variable i.e. square_root. After this, again take the sqrt() of the result previously computed and display the final result.
public class FourthRoot{
public static void main(String[] args) {
double square_root;
double number=81;
square_root=Math.sqrt(number);
System.out.println("Fourth Root of 81 is: "+ Math.sqrt(square_root)); } }
The program along with its output is attached in a screenshot.

A customer contacts the help disk stating a laptop does not remain charged for more than 30 minutes and will not charge more than 15%. Which of the following components are the MOST likely causes the issue? (Select three.)
A. LCD power inverter
B. AC adapter
C. Battery
D. Processor
E. VGA card
F. Motherboard
G. Backlit keyboard
H. Wireless antenna
Answer:
A, B and C
Explanation:
When talking about a computer or laptop charging, there are ONLY 3 things that matter.
The Battery - This is where the electricity or "wall juice" is stored.
AC Adapter - This is how the Battery gets its juice, it plugs into the computer itself.
LCD Power Adapter - This plugs into the wall to pull the electricity from the grid into your computer passing through AC Adapter.
On a side note... the most logical reason the computer could not be going over 15% nor charge anymore than 30mins is because the battery has been shortened by either a storm or a power surge.

Write a program that asks a user to predict how many rolls of a single die it will take to reach 100. When all rolling is finished, compare the given answer to the results and let them know if they did well or not.
Answer:
import random
guess = int(input("Make a guess: "))
total = count = 0
while total < 100:
roll = random.randint(1, 6)
total += roll
count += 1
if guess == count:
print("Your guess is correct")
elif guess > count:
print("Your guess is high")
else:
print("Your guess is low")
Explanation:
*The code is in Python.
Import the random module to simulate the dice roll
Ask the user to make a guess
Initialize the total and count as 0
Create a while loop that iterates while the total is smaller than 100. Inside the loop, use random to get a random number between 1 and 6 and set it to the roll. Add the roll to the total. Increment the count by 1.
When the loop is done, check the guess and count. If they are equal, that means the guess is correct. If the guess is greater than the count, that means it is high. If the previous cases are not true, then the guess is low.

A TCP ________ segment is a request to the other transport process to close a connection. ACK FIN SYN CLS
Answer:
FIN
Explanation:
A TCP is an acronym for Transmission Control Protocol and it is one of the essential and important protocol of the internet protocol network. This simply means that, it is an essential part of the TCP/IP network.
The TCP has a wide range of applications in the following areas, file transfers, world wide web, remote administration, e-mail, etc.
The TCP connection are mainly established in the network using the three-way handshake.
A TCP FIN segment is a request to the other transport process to close a connection. The FIN in transmission control protocol (TCP) is an acronym for finish and it involves the packets associated with termination or closing of a network connection.
Generally, the TCP in networking is made up of all of the following flag bits, namely;
1. SYN: used for synchronizing packets associated with a connection.
2. ACK: this is mainly where an acknowledgement of packets in a network takes place.
3. FIN: it is used for closing connections.
4. PSH: used for pushing packets that are to meant to be delivered at the far end.
5. RST: used as a reset in times of errors in the connection.
6. URG: used to denote urgent and high priority packets in the network.
