magnitude and the probability of it occurring

Explanation:

In every single study that involves an individuals risk of self-harm there are two variables that need to be evaluated, and those are the magnitude and the probability of it occurring. In other words how likely is the individual to hurt themselves and if they do, to what extent (physical, emotional, death). By evaluating this can allow you to take action if things get to serious, or even prevent something from happening that can lead that person that is at risk from hurting themselves.

Answer:

Each object of this class has its own copy of GREETING

Explanation:

option c: Each object of this class has it’s own copy of GREETING

This is the only false statement.  When a variable is preceded by the Static key word only one copy of that variable is created, no matter the amount of object created from the instance of that class.

option a: Each object of this class can access GREETING, this is true.

option b: The value of GREETING can’t be changed in any methods, this is true because GREETING is preceded by the keyword final.

option d: GREETING.length() = 2, this is true because the method length() is use to get the length of the string "Hi" which is 2.

option e: GREETING.toUpperCase() = "HI", this is also true because the method toUpperCase()  convert all the character of "Hi" to uppercase.

Note: All these are peculiar to java programming language.

Final answer:

Explanation of the incorrect statements regarding the static field declaration in a Java class.

Explanation:

b) The value of greeting can’t be changed in any method: This statement is not true because even though the field is declared as 'final', it can still be accessed and modified using reflection.

c) Each object of this class has its copy of GREETING: This statement is not true. Static fields in Java are shared among all instances of a class, so all objects of the class will have the same value for a static field.

d) GREETING.length() = 2: This is true since the length of the string 'Hi' is 2.

Answer:

Correct Order

2. Select the cell or range you want to move or copy.

1. Move the pointer over the border of the selection until the pointer changes shape.

3. To move the range, click the border and drag the selection to a new location, or to copy the range, hold down the Ctrl key and drag the selection to a new location.

Explanation:

To move or copy range of cells in MS Excel, You first select the cell/range you want to move or copy, hover the mouse pointer and take note when it changes shape, then finally click the border (when you noticed the change of shape of the pointer) and hold down the ctrl key and drag it to the destination location.

To move or copy a range of cells, select the range, hover over the border so the cursor changes shape, and then drag to the new location with or without holding Ctrl for copying. Utilizing Excel's features like cherry-picking for non-contiguous cells and AutoFill for formulas enhances productivity and accuracy.

To move or copy a range of cells in applications like Microsoft Excel, you should follow these steps:

Selecting non-contiguous cells can be done by clicking the first cell, holding down the Ctrl key, and clicking each additional cell you want to include. This method, known as "cherry-picking" cells, allows for flexibility in selecting a range that is not adjacent. Similarly, utilizing keyboard shortcuts like Ctrl+A can select the entire worksheet while the Ctrl key can also help in selecting non-adjacent rows or columns.

To perform actions like cut, copy, and paste, Excel utilizes the Clipboard, where data is temporarily stored when it is cut (using Ctrl+X) or copied (using Ctrl+C). You can then paste the data (using Ctrl+V) to the desired destination. Taking advantage of Excel's AutoFill feature can save time when copying and pasting formulas, which updates relative cell references automatically.

When performing data analysis or formatting, it's important to first highlight the correct data range. It should be noted that blank rows and columns in a dataset can affect the auto-selection of a data range in Excel for tasks such as sorting.

Answer:

Option (D) is the right answer.

Explanation:

DHCP term used as a short form of dynamic host configuration protocol, which is used to assigns the IP address automatically according to the network.

According to the scenario, the system is getting the wrong IP address that resulting in internet disconnection which is a failure of the DHCP server because it is responsible for assigning the right IP address to the system.

Hence option (D) is the most appropriate answer.

While other options are wrong because of the following reasons:

Final answer:

The computer has been assigned an APIPA address, indicating it couldn't reach the DHCP server. The correct cause is an unreachable DHCP server, causing the computer to self-assign this IP address.

Explanation:

When a computer is assigned an IP address such as 169.254.100.88, this is known as an Automatic Private IP Addressing (APIPA) address. It generally means that the computer has failed to obtain an IP address from the Dynamic Host Configuration Protocol (DHCP) server. Common causes of this issue could include network configuration errors, DHCP server failure, or the absence of a DHCP server on the network. APIPA addresses are self-assigned by the computer when it is configured to obtain an IP address automatically and cannot reach the DHCP server.

In this case, the correct answer to what could cause a computer to get such an IP address is d. unreachable DHCP server. This scenario typically does not involve interference from surrounding devices, static IP addressing, or a reduced computer power supply output.

Final answer:

The question involves writing two programs for the Springfork Amateur Golf Club: one to save each player's name and golf score to a file, and another to read and display these records from the file, illustrating the use of file input and output in programming.

Explanation:

The request involves two primary tasks related to file input and output in programming: creating a file to store records and reading from that file to display the records. This practice is essential in developing applications that need to persist data across sessions. By understanding how to implement both tasks, students will gain valuable insight into how software applications manage data.

This program should prompt the user for player names and scores, creating a record for each and writing these records to a golf.txt file. It's important to handle file operations carefully to avoid data loss or corruption. Each record would ideally have separate fields for the player's name and score, ensuring structured data storage.

The second program will read the records stored in the golf.txt file and display them. This task involves opening the file in read mode, iterating over each line (assumed to represent a record), and parsing the line into its component fields to be displayed. Such a program demonstrates reading from and interpreting external data sources.

Answer:

In the given question, Tim is exhibiting object permanence.                

Explanation:

Object permanence is the comprehension that an object continues to exist even when it cannot be perceived in any way which means that when object cannot be sensed ( heard,seen,touched).  

It is a basic concept of developmental psychology, that deals with the development of young children's social and mental capacities. It was studied and presented by developmental psychologist Jean Piaget . According to Piaget, object permanence is a significant developmental stage in the first two years of a child’s life. Piaget proposed a series of 6 stages which describes when and how object permanence advances  during the first two years of life.  Children first begin to develop an idea of object permanence at around 8 months old. Other studies shows that this ability begins at a younger age.

Explanation:

Final answer:

The behavior of frequently checking for the mail carrier is an example of a variable interval schedule of reinforcement, where rewards are given at unpredictable time intervals, producing a steady response rate.

Explanation:

Your behavior of glancing out of the window frequently as the regular delivery time approaches is typical of what is known as a variable interval schedule of reinforcement. This schedule provides reinforcement at unpredictable time intervals, leading to a moderate, steady rate of the behavior in anticipation of the reinforcement (in this case, the arrival of the letter carrier).

Unlike continuous schedules where the behavior is reinforced every time, or fixed-ratio schedules where reinforcement is given after a set number of responses, variable interval schedules do not specify when the next reinforcement will be given after the last one, causing the constant anticipation of the reward.

Answer:

Firewall

Explanation:

Firewalls are mainly intended to protect an individual computer system or network from being accessed by an intruder, especially via the Internet. They thus work to prevent sabotage of the system and the theft or unauthorized viewing of private or sensitive data, such as through the use of spyware.

Final answer:

Luis should install a "firewall" to protect against identity theft by serving as a barrier that controls network traffic and prevents unauthorized access to his computer's resources.

Explanation:

To protect yourself from identity theft and ensure the security of your network resources, it's important to install a program known as a firewall. This software acts as a barrier between your computer and the internet, controlling incoming and outgoing network traffic based on an applied rule set. It helps to prevent unauthorized access to your system, which can be crucial for protecting sensitive personal information from cybercriminals.

A firewall is different from programs that monitor Web usage, which may be used in work settings to ensure employees are focused on work-related tasks. While both are concerned with the use of the internet, a firewall is specifically designed to protect against intrusions and hacking attempts.

Answer:

TCP

Explanation:

Answer:

TCP

Explanation:

FTP (File Transfer Protocol) can be found in the Application layer of the TCP/IP model and the Application layer of the OSI model not on the Transport layer of the TCP/IP model as stated in the question.

In the Transport layer, we have end-to-end message transmission or application connection, which can be grouped as connection-oriented or connectionless. Connection-oriented is implemented in TCP (Transmission Control Protocol) while connectionless is implemented in UDP (User Datagram Protocol), which are the two major protocols found in the Transport Layer of the TCP/IP model. The choice of TCP as the correction option out of the four options given is based on the fact that FTP is a protocol found in the Application layer of TCP/IP

FTP is a network protocol used to receive and send files between machines on a TCP/IP network using ports 20 and 21. This protocol uses a client-server architecture, an FTP client is installed on the client and used to establish the connection to an FTP server running on a remote machine. FTP supports user authentication, so when a connection has been established and the user authenticated, data can be transferred between them. All data are sent in clear text, be it usernames or passwords. For secure transmission that protects the username and password, and encrypts the content, FTP can be secured with SSL.TLS or replaced with SSH File Transfer Protocol (SFTP). A connection to port 21 from the FTP client forms the control stream on which commands are passed to the FTP server and responses are collected. The parameters for the data streams depend on the specifically requested transport mode. Data connection usually uses port 20.

Network Access Control systems can perform a health check on devices to make sure they meet minimum security standards prior to connecting. Permanent NAC would have an impact on visitor devices; agentless NAC has less impact and COPE devices aren’t possible to give to guests.

The possible cause of the problem on application keep on crashing in user's PC lies on the computer's operating system.  

The computer's operating system performs automatic updates (sometimes being set into manual updates). Either way, updates can cause applications to crash if it is being installed wrongly. Sometimes due to slow internet connection, updates get paused and will cause problems in your computer. You can apply the following steps to fix applications that keep on crashing:

A virus infection on the computer could be the source of the problem.

Some computer viruses are designed to damage your computer by destroying files, corrupting applications, or reformatting the hard drive. Others just clone malware or flood a system with traffic, rendering all internet activity impossible.

There are various ways for a computer to become infected with a virus, the majority of which involve downloading malicious files, either purposefully or unwittingly. Pirated music or movies, photographs, free games, and toolbars, as well as malware emails with files, are all prominent offenders.
