   shapearea = 0

   pieval = 3.14

   if _input_ == "Square":

Base band : A list of radio frequencies

PRI : The chip that controls the radio frequency waves within a device

PRL: The connection between a mobile device and radio tower

Explanation:

Base-band is the range or band of frequencies. It contains a number of between upper and lower limit of the frequency. For example if the range of transmission of the signal is 2khz to 3khz. The frequencies between this range are called base band.

PRI is the chip that is used to control the different frequencies received at the device. This chip control the radio frequencies that are allowed to the devices. It is the short form of primary rate interface.

PRL is the list named as Preferred Roaming List. It has stored the information of the mobile devices that are connected to the mobile phone. This list is used while communicating between mobile device and tower.

Answer:

Modify the NTFS permissions on the folder.

Explanation:

While any user using a folder on his Ms Windows Operating System and he wanted to share that folder with his team members by which they can view and modify any file in that shared folder. Then, He has to provide Full Control permission to that folder by which they can only view that file but they cannot modify it.

So, He has to modify the NTFS permission on the following folder by which only those people can view that folder who has logged in over the server.

Final answer:

The problem with users being unable to modify files in a shared Windows folder can typically be resolved by adjusting the NTFS permissions on the files or folder to grant the correct level of access for editing. This involves ensuring that the necessary user groups have the 'Modify' permission set under the folder's Security properties.

Explanation:

If users can open files in the shared folder but cannot modify them, this suggests that the NTFS permissions on the files or the parent folder may not allow for modifications, despite the share permissions being set to Full Control for Everyone. Share permissions and NTFS permissions work together to provide the final level of access for a user. Since the issue at hand deals with users being able to read but not write or edit files, it's important to check the NTFS permissions.

To resolve the issue, you need to perform the following steps:

By ensuring that both share and NTFS permissions are set correctly, you will enable your development team to view and edit files within the shared folder.

Answer:

misspelling a programming language word

Explanation:

Syntax error is the type of error in programming, when the programmer insert some symbol that is not present in directories or libraries, the programmer not followed the rules of that particular programming language that is understandable to compiler.

For example in C++, it is necessary to insert the semicolon (;) after each statement. If the programmer not insert the semicolon after each statement, the program will show the syntax error.

If the programmer use integer instead of int to assign datatype to the variable in C++, it will also leads to the syntax error. Because in C++ library, Integer is defined with the help of "int".

Answer:

Technical controls.

Explanation:

In a network, data is transmitted in form of packets and frames within a network or between networks. Users with authorised access to a network and a end device can easily access its services with the required tools.

Cyber attackers exploit vulnerabilities in networks to access information and services. For this technical control means are implemented. It uses technology as a mean of controlling access to networks and information.

Technologies like firewall, intrusion detection and prevention devices, antivirus and encryption are examples of technical control mechanism for access control.

The Counter class definition in C++ includes a private integer data member, a constructor, increment and decrement functions, and a getValue function to manage and retrieve the counter's value.

To write a full class definition for a class named Counter, which includes various members such as a data member, a constructor, and functions to increment, decrement, and get the value of the counter, the following C++ code can be used:

This class consists of an int type data member named counter, a constructor that initializes this data member, an increment function which increases the counter by one each time it's called, a decrement function which does the opposite by decreasing the counter by one, and a getValue function that returns the current value of the counter. These members encapsulate the main functionalities expected from a counter.

Answer:

int widthOfBox; //declaration

int widthOfBook; // declaration

if (widthOfBox%widthOfBook!=0){

}

Explanation:

This expression will evaluate to true if the value of widthOfBox is not divisible by widthOfBook.

The modulo operator (%) is used for this evaluation since widthOfBox %widthOfBook will evaluate to zero if the widthOfBox is divisible by  widthOfBook
