Answer:
True
Explanation:
There are usually thousands of line of code and the programmers have to account for serveral different things. For that reason, most complex games will have at least some bugs.
In a TCP connection, the initial sequence number at the client site is 2,171. The client opens the connection, sends only one segment carrying 1,000 bytes of data, and closes the connection. What is the value of the sequence number in each of the following segments sent by the client?
a. The SYN segment?
b. The data segment?
c. The FIN segment?
explain for full credit
Answer:
a. 2171
b. 2172
c .3172
Explanation:
a . As we know that sequence number is 32 bits has a two responsibility
When the SYN flag is set to the value 1 then that is the number of a initial list. That sequence number +1 is then the sequence number of the real initial data bit.When the SYN flag is set to the value 0 then for the current session is equals to the average sequence number of this section's initial data Bit.Initially the sequence number at the client site is 2,171 that is equals to the he SYN segment i.e 2171.
b The data segment is determined by the following formula
[tex]=sequence \ number\ in\ the\ client site\ +\ 1[/tex]
[tex]=2,171 +1[/tex]
[tex]=2172[/tex]
c As mention in the question there are 1,000 bytes of data,
so FIN segment can be determined by the
[tex]=2171+1000+1[/tex]
[tex]=3172[/tex]

how does making a phone differ when using public phone box and cell phone
Answer:
The public phone box transmit electronic signals through cable while cell phones transmit electromagnetic signals wirelessly.
Explanation:
Public phone boxes are reserved booth for making calls. It uses dial tone frequency to tap to a receiver's frequency. They use a dedicated cable line to transmit electronic signals to a central automatic switch that relays the signal to the recipient's line.
A cell phone has antennas that transmits the electromagnetic wave signal to a cell tower, which in turn transmit to other towers to locate the receiver. The receiver's antenna receives the signal and connection is made.
Write a program that reads a file name from the keyboard. The file contains integers, each on a separate line. The first line of the input file will contain the number of integers in the file. You then create a corresponding array and fill the array with integers from the remaining lines. If the input file does not exist, give an appropriate error message and terminate the program. After integers are stored in an array, your program should call the following methods in order, output the intermediate results and count statistics on screen, and at end output even integers and odd integers to two different files called even.out and odd.out.
Implement the following methods in the program:
* public static int[] inputData() – This method will ask user for a file name, create an array, and store the integers read from the file into the array. If input file does not exist, give an appropriate error message and terminate the program.
* public static void printArray(int[] array) – This method will display the content of the array on screen. Print 10 integers per line and use printf method to align columns of numbers.
public static void reverseArray(int[] array) – This method will reverse the elements of the array so that the 1st element becomes the last, the 2nd element becomes the 2nd to the last, and so on.
* public static int sum(int[] array) – This method should compute and return the sum of all elements in the array.
* public static double average(int[] array) – This method should compute and return the average of all elements in the array.
* public static int max(int[] array) – This method should find and return the largest value in the array.
* public static int min(int[] array) – This method should find and return the smallest value in the array.
* public static void ascendingSelectionSortArray(int[] array) – This method will use Selection Sort to sort (in ascending order) the elements of the array so that the 1st element becomes the smallest, the 2nd element becomes the 2nd smallest, and so on.
* public static void desendingBubbleSortArray(int[] array) – This method will Bubble Sort to sort (in descending order) the elements of the array so that the 1st element becomes the largest, the 2nd element becomes the 2nd largest, and so on.
* public static void outputData(int[] array) – This method will create two output files called even.out and odd.out. Scan through the entire array, if an element is even, print it to even.out. If it is odd, print the element to odd.out.

In this project, you’ll create a security infrastructure design document for a fictional organization. The security services and tools you describe in the document must be able to meet the needs of the organization. As the security consultant, the company needs you to add security measures to the following systems:
a. An external website permitting users to browse and purchase widgets
b. An internal intranet website for employees to use
c. Secure remote access for engineering employees
d. Reasonable, basic firewall rules
e. Wireless coverage in the office
f. Reasonably secure configurations for laptops
Since this is a retail company that will be handling customer payment data, the organization would like to be extra cautious about privacy. They don't want customer information falling into the hands of an attacker due to malware infections or lost devices. Engineers will require access to internal websites, along with remote, command line access to their workstations.
Answer:
Explanation:
It is very important for the organisation to implement maximum security to the infrastructure. The main data totally belongs to the customers which mainly has customers' personal information and bank details. So, here are few things that needs to be look at as a security expert:
Encryption: the implementation of encryption tool to encrypt the data especially passwords and card details of the customer will be help in securing the infrastructure. Encryption makes it hard for anyone to be able decrypt the actual data.
Firewall: This is the beginning stage of implementing security to an infrastructure. Firewall will help greatly in blocking traffic that are unwanted from entering into the infrastructure. This also blocks untrusted traffic to the application server too.
SSL certificate: Implementation of SSL certificate to the website or the application will help greatly in securing and protecting the application for you against online hackers.
Every device belongs to your system must be implemented with anti-malware softwares that can able to detect malware present in the system.

Select the correct statement regarding channelized T-1.
a. Each T-1 frame supports 24 DSOs, therefore, the frame rate must be 64 frames per second
b. Channelized and unchannelized T-1 frames must support 24 DSOS
c. Each channelized T-1 frame contains 193 bits
d. Each T-1 frame supports 24 64kbps channels. Therefore, each frame length is 24 x 64,000 = 1,536,000 bits long.
Answer:
The answer is "Option c".
Explanation:
The Embedded T1 also known as channelized T1, it is a digital modulation system in which a T1 channel is split into 24 channels, in which each has the maximum connection speeds of 64,000 bits per second (Kbps) each of capable of supporting a specific application, which can run simultaneously to, but separately of, other programs on various channels, in this channelized T-1 the frame length is 193 bits long, and wrong choices can be described as follows:
In option a, It supports only 1 bit per second. In option b, only channelized T-1 frames support 24 DSOS. In option d, It length is 8000 frame per second.A vice president at Alexander Rocco Corporation says he received a hostile e-mail message from an employee in the Maui office. Human Resources has informed him that the message contents are grounds for termination, but the vice president wonders whether the employee actually sent the message. When confronted, the employee claims he didn't send the message and doesn’t understand why the message shows his return address.
Required:
Write a memo to the vice president, outlining the steps an employee might have taken to create an e-mail message and make it appear to come from another employee’s account. Be sure to include some SMTP commands the culprit might have used.
Answer:
=> E-mail is sent using SMTP server by using command such as;
telnet smpt.server.name 25.
(Where 25 = port and telnet smpt.server.name = name of the server).
Explanation:
Date: June 2, 2020.
To: The vice president.
From: Codedmog101
SUBJECT: E-mail Forging.
Due to the recent issue going on in the company concerning an employee sending a message to you, I saddled with the responsibility of writting to you the steps an employee might have taken to create an e-mail message and make it appear to come from another employee’s account.
(1). The SMTP servers can be configured in such a way that it can be used by spammers to send message to another person(recipient) and it will look like it is not the spammer that sent it.
(2). The person spamming another person will use an unsecured SMTP servers with command such as the one given below;
telnet smpt.server.name 25.
(3). Once (2) has been connected, the spammer can then input the e-mail of the person he or she is spamming.
(4). The recipient address will be type in by the spammer too
(5). The subject, date and the body then enter.
(5). After (5) above the message will be sent to the recipient from the spammer but it will indicate another person.
These are the steps taken to create an e-mail message and make it appear to come from another employee’s account.

A data warehouse differs from an operational database in which of the following ways?Select one:a. Data in a data warehouse are not stored in tablesb. Data warehouses do not use primary key / foreign key relationshipsc. Data warehouse data are often stored in a dimensional databased. Both b and c are correct
Answer:
The second last point i.e "Data warehouse data are often stored in a dimensional databased " is the correct answer to the given question .
Explanation:
The main objective of the operation applications is implemented and enable the handling of large volumes transactions where as the data warehouses objective of the applications is implemented and enable the handling of large volumes of analytical transactions.
The operational database is deal with the current data where as the data warehouse are deal with the historical data .The operational database is deal with the business of real time where as the data warehouse is deal with analysis processing .All the other options are not correct for the data warehouse difference from the operational database that's why these options are incorrect .
