which type of communication path-sharing technology do all 802.11 standards for wireless networking support? answer csma/cd polling token passing csma/ca
The type of communication path-sharing technology that all 802.11 standards for wireless networking support is CSMA/CA.
What is CSMA/CA? Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is a wireless networking access control method used in wireless LANs. CSMA/CA is based on the CSMA (Carrier Sense Multiple Access) protocol, which is used in wired networks to reduce packet collision. The primary difference between CSMA/CA and CSMA/CD (used in wired networks) is that CSMA/CA attempts to avoid collisions rather than resolving them when they occur. CSMA/CA listens for other signals on the wireless network before transmitting data to ensure that there is no other transmission in progress. CSMA/CA uses random backoff times and acknowledges every received packet.

what type of programming practice defends against injection-style attacks, such as inserting sql commands into a database application from a site search form (select two)?
By implementing these two programming practices, developers can help to prevent injection-style attacks and protect the security of their applications and user data.
The two programming practices that defend against injection-style attacks, such as inserting SQL commands into a database application from a site search form, are:Parameterized queries: This practice involves using placeholders for user input in SQL statements, which are then replaced with the actual values at runtime. This technique prevents malicious users from inserting SQL commands into user input fields, as the input is treated as a value and not as part of the SQL statement.Input validation: This practice involves checking user input to ensure that it meets the expected format and values before it is processed by the application. This can prevent attackers from inserting malicious SQL commands or other types of harmful input into the application. Input validation should be performed on both the client-side and server-side of the application.For such more question on programming

the machine you are working on has the ip address 192.168.86.68, a subnet mask of 255.255.255.0, and a default gateway of 192.168.86.1. an application on your machine needs to send a message to a machine with an ip address of 192.168.101.2. which ip address will your machine send the packet to first?
When an application on the machine sends a message to a machine with an IP address of 192.168.101.2, the IP address to which the machine will send the packet first is the default gateway IP address, which is 192.168.86.1.
In order to understand this, let's break down the given information.
1)The machine has an IP address of 192.168.86.68, which falls under the Class C IP address range. The subnet mask of the machine is 255.255.255.0, which means that the first three octets of the IP address are used to identify the network and the last octet is used to identify the host. The default gateway IP address is 192.168.86.1, which is the IP address of the router that connects the local network to other networks.
2)When the application on the machine needs to send a message to a machine with an IP address of 192.168.101.2, the machine first needs to determine whether the destination machine is on the same network or a different network.
3)Since the subnet mask is 255.255.255.0, the machine can determine that any IP address that starts with 192.168.86 is on the same network. However, the destination machine has an IP address of 192.168.101.2, which is on a different network.
4)Therefore, the machine needs to send the packet to the default gateway IP address, which is 192.168.86.1. The router will then forward the packet to the appropriate network and ultimately to the destination machine with the IP address of 192.168.101.2.

A computer technician has set up a NAS (Network Attached Storage) for a company using two 1 TB hard drives operating at 7200 RPM in a RAID 1 configuration. In this setup, the usable storage space is 1 TB.
RAID 1 provides redundancy by mirroring the data on both hard drives, ensuring that if one drive fails, the data remains available on the other drive. However, this redundancy means that the total usable storage space is equal to the capacity of one hard drive, which in this case is 1 TB.
Since the technician has installed two 1 TB hard drives, the total capacity of the NAS is 2 TB. However, in RAID 1 configuration, the data is mirrored, which means that only one of the hard drives is being used to store data. Therefore, the usable storage space in the NAS would be 1 TB.
Note that the actual usable storage space may be slightly less than 1 TB due to formatting and other overheads associated with the operating system and file system used on the NAS.

compare and contrast integrity controls and security controls. why isn't there a separate activity to design them?
Integrity controls and security controls can be contrasted and compared in the following ways: Contrast integrity controls and security controls: These terms are different from each other in terms of the intended objective.
In contrast to integrity controls, security controls are designed to provide protection to computer systems and software from unauthorized access, theft, damage, and other types of threats. Security controls, on the other hand, use encryption, passwords, and authentication to restrict access to data and ensure that it is only seen by authorized individuals.
Comparing integrity controls and security controls: Integrity controls are focused on ensuring that data and records are maintained in their original, complete, and accurate format.
Access controls are an example of integrity controls that restrict unauthorized users' access to critical data, such as financial records or personnel files. On the other hand, security controls provide an extra layer of protection by restricting access to sensitive data, such as bank account information or patient records. They could also limit the spread of malicious software like viruses, Trojans, and worms. Why isn't there a separate activity to design them?
There is no separate activity to design them because, while integrity controls and security controls have different objectives, they often overlap in practice. Therefore, there is a lot of discussion and debate about which types of security and integrity controls should be used, and how they should be implemented to achieve the desired results. For instance, access controls can also be used as security controls to limit access to sensitive data or systems that could be compromised by hackers. As a result, it's difficult to design separate controls for each category, and a holistic approach is preferable.
To compare and contrast integrity controls and security controls, both are essential components of a comprehensive information security strategy. Integrity controls focus on maintaining the accuracy and consistency of data to ensure it has not been altered or tampered with, while security controls encompass a broader range of measures aimed at protecting information systems from unauthorized access, use, disclosure, disruption, or destruction.
Integrity controls may include data validation checks, checksums, and digital signatures, whereas security controls involve administrative, technical, and physical measures like access controls, encryption, and security awareness training.
The reason there isn't a separate activity to design integrity controls and security controls is that they are often integrated into the overall security design of an information system. By incorporating both types of controls into a single design process, organizations can ensure a more comprehensive and cohesive approach to protecting their information assets. The step-by-step process for designing these controls involves identifying risks, selecting appropriate controls, implementing them, and continuously monitoring their effectiveness.

Understanding the basic characteristics of different types of memory is crucial in matching them with specific attributes
In order to match the type of memory with the given attributes, we need to understand the basic characteristics of different types of memory. Volatile memory refers to memory that loses its stored data when there is no power supply, while nonvolatile memory retains the stored data even when there is no power.
Random access memory (RAM) allows for accessing any memory location randomly with the same amount of time, while sequential memory requires accessing memory locations in a specific sequence. Virtual memory is a type of memory management technique that allows the operating system to use a portion of the hard drive as if it were RAM.
With these definitions in mind, we can now match the given attributes to the appropriate type of memory. The attribute "retains what is in it when there is no power" matches with nonvolatile memory, while "looses what is in it when there is no power" matches with volatile memory.
"Accesses to memory locations take the same amount of time" matches with random access memory, and "accesses to memory locations take different amounts of time" matches with sequential memory. Finally, "utilizes secondary storage" matches with virtual memory.

1. Set the Work vector equal to the Available vector: Work = [1, 5, 2, 0].
2. Find a process (Pi) for which Need_i <= Work and Finish_i = false.
3. If such a process exists, set Finish_i = true and Work = Work + Allocation_i. Repeat step 2.
4. If all processes have Finish_i = true, then the system is in a safe state.
Applying the algorithm, we get the following safe sequence: P0 → P3 → P4 → P2 → P1.
c. To check if the request from P1 for (0, 4, 2, 0) can be granted immediately, we compare it to the Available vector:
Request = [0, 4, 2, 0]
Available = [1, 5, 2, 0]
Since the request is within the available resources, the request can be granted immediately.

which of the following best describes roaming? answer a deployment model used by newer wireless networks. a model that connects wired and/or wireless networks. the name of the wireless network that is broadcasted from an ap. the ability to broadcast the same ssid across multiple aps.
The best answer to describe roaming is D. the ability to broadcast the same SSID (Service Set Identifier) across multiple Access Points (APs).
This allows users to move freely from one area to another without losing connectivity to the network. In other words, as a user moves from one AP to another, the device automatically switches to the strongest signal without any interruption in service. Roaming is important in wireless networks as it ensures that users can access the network from different locations without needing to reconfigure their devices each time they move to a new area. Roaming is particularly important for businesses that require wireless connectivity across a large physical area such as hospitals, universities, and airports.
In conclusion, roaming is the ability to broadcast the same SSID across multiple APs, allowing users to move freely from one area to another without losing connectivity to the network. It is an essential feature of modern wireless networks that allows users to access the network from different locations without any interruption in service. Therefore, the correct option is D.

a user is attempting to access a shared file. the file has full control ntfs permissions and read permissions at the share level. what is the effective permission for the user on the file?
If a user is attempting to access a shared file, the file has full control NTFS permissions and read permissions at the share level, then the effective permission for the user .
on the file is Full Control.What are file permissions?File permissions are a set of access control instructions that are used to define what action a user can take on a file or folder in the operating system. They grant or restrict access to files on the system, and they are the mechanism by which we control who can read or write files.There are three main types of file permissions:Read: This enables the user to view the contents of the file.Write: This allows the user to make changes to the file.Execute: This allows the user to execute the file or program.NTFS stands for New Technology File System, which is a file system used by the Windows operating system. NTFS provides advanced features like file-level encryption, large file support, and improved performance over its predecessor, the FAT file system.

(in java please) when analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. this adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers.for this program, adjust the values by dividing all values by the largest value. the input begins with an integer indicating the number of floating-point values that follow. assume that the list will always contain fewer than 20 floating-point values.output each floating-point value with two digits after the decimal point, which can be achieved as follows:system.out.printf("%.2f", yourvalue);ex: if the input is:5 30.0 50.0 10.0 100.0 65.0the output is:0.30 0.50 0.10 1.00 0.65 the 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0.for coding simplicity, follow every output value by a space, including the last one.

how are voice communications converted to digital signals? question 4 options: they are broken into very small samples and then binary values are assigned to them. they are converted into an analog frequency from a digital signal then transmitted. they are sent directly as a digital signal; there is no conversion needed. they are converted to a cellular format, assigned a binary value, and then transmitted.
Answer: They are broken into very small samples and then binary values are assigned to them
Explanation:
First the signal is turned from analog to digital using ADC thus the proving option 2 wrong
They cannot be send directly as as digital signal as communications are first recorded in analog, thus option 3 is wrong
Conversion to a cellular format is not required thus option 4 is wrong
When voice communications are converted to digital signals, they are broken into very small samples, and then binary values are assigned to them.
A digital signal refers to a sequence of discrete values that represent information by encoding it as a string of binary values. In contrast to an analog signal, a digital signal has a finite number of defined values within a set range of values. Voice communication is converted to digital signals because digital signals are easier to transmit, store, and manipulate than analog signals.
Digital signals are less prone to interference and noise than analog signals. As a result, digital signal has gained popularity in communication technology.
