If you are referencing cell (C2)in Excel and want to be able to copy the formula and update the column and keep the row fixed, how do you reference the cell in a formula, you don't need to include the
Answers
When you reference cell (C2) in Excel and want to copy the formula and update the column while keeping the row fixed, you can use a mixed cell reference.
A mixed cell reference refers to a reference that combines both relative and absolute cell reference by using a dollar sign ($).A dollar sign can be used to change a reference to either absolute or relative. If you want to keep a cell reference the same when copying a formula, you can use an absolute reference. To create an absolute reference in a formula, place a dollar sign ($) before the column letter and row number of the cell you want to reference.
To create a mixed cell reference in Excel, place a dollar sign before either the column letter or the row number depending on which you want to be fixed.For instance, to fix a row and allow a column to change, place a dollar sign before the row number as in $C2. When the formula is copied, the row will remain the same while the column will change. To fix a column and allow a row to change, place a dollar sign before the column letter as in C$2.

An operating system can be organized in a layered, hierarchical structure, where the inner most layers ________.a) host the kernel.b) hold the microkernel.c) are visible to the user.d) interact with the hardware.
Answers
An operating system can be organized in a layered, hierarchical structure, where the inner most layers interact with the hardware. So option d is the correct one.
The layers in an operating system are usually designed to work together in a way that ensures efficient communication between the different components of the system. The hardware abstraction layer (HAL) is an example of a layer that interacts with the hardware, providing a common interface for the operating system to communicate with different hardware devices. This layer allows the operating system to be hardware-independent, making it easier to port the operating system to different hardware platforms. The kernel is another layer that is usually located close to the hardware. It provides low-level services such as memory management, process scheduling, and device drivers. Other layers such as the device manager and file system layer interact with the kernel to provide higher-level services to the user. Overall, the layered, hierarchical structure of an operating system allows for efficient communication and coordination between the different components of the system, leading to a more stable and reliable operating environment.

Can you guess which problem it is? Also, can you say to which approach the above Pseudo-code does indicate? Is it Dynamic Programming or Greedy? Justify your answer with proper short explanation.
Answers
The following is the solution to the provided Pseudo code in C++ programming language. As for which problem this Pseudo code gives a solution for, it is the problem of finding the path with minimum weight in a matrix from its top-left corner to its bottom-right corner, known as the Minimum Path Sum problem.The above Pseudo code shows the Greedy approach of solving the Minimum Path Sum problem. This is because at each cell of the matrix, it always picks the minimum of the right and down cell and moves there, instead of keeping track of all paths and comparing them, which would be the Dynamic Programming approach. Hence, it does not require to store all the sub-problem solutions in a table but instead makes a decision by selecting the locally optimal solution available at each stage. Therefore, we can conclude that the above Pseudo code does indicate the Greedy approach to the Minimum Path Sum problem in computer programming.Explanation:After receiving input of the dimensions of the matrix and the matrix itself, the Pseudo code declares a variable VAL and initializes it with the first cell value of the matrix. It then uses a while loop to iterate through the matrix till it reaches its bottom-right corner. At each cell, it checks if it can only move to the right or down, and then it moves in the direction of the minimum value. VAL is then updated by adding the value of the current cell to it.After the loop is exited, the last updated value of VAL is printed, which is the minimum path sum value.

The method with the declaration public static char procedure(double d) has a method type of ___________________.
Answers
The method with the declaration public static char procedure(double d) has a return type of char.
In Java, the return type of a method indicates the type of value that the method will return when it is called. In this case, the return type is explicitly declared as char, which means that the method will return a single character value.
The public keyword denotes the visibility of the method, indicating that it can be accessed from anywhere in the program.
The static keyword means that the method belongs to the class itself rather than to any specific instance of the class.
This allows the method to be called using the class name directly, without needing to create an object of the class.
The method name, in this case, is "procedure," which can be any valid identifier chosen by the programmer to describe the functionality of the method.
The method parameter is declared as double d, which means that when the method is called, a double value should be passed as an argument.
The method can then use this value within its body to perform certain computations or operations.

You are the network administrator for a small consulting firm. the firm has recently rolled out a new intranet site, and you are responsible for configuring the dns.
Answers
As a network administrator, the setting that needs to be set up to enable hostname access to the website is Forward lookup zone. A forward DNS lookup is another name for forward DNS.
A domain name is used to acquire its matching IP address in a forward DNS request. When a DNS server returns the domain's IP address, it is considered to have resolved the domain name. Reverse DNS lookups are the inverse of the forward DNS request.
A computer, server, smartphone, or other end client can translate a domain name or email address into the address of the device that would handle the subsequent connection using forward DNS. All IP-based networks, including the Internet, utilize forward DNS to function, even though it is fully transparent to human end users.
When a user writes a web page URL or email address in text form, Forward DNS operates. First, a DNS server receives this message. Following a record check, the DNS server returns the domain's IP address. The DNS server sends the request to a different server if it is unable to find the domain's IP address. Once the numerical IP address is known, communication can resume after the DNS query is finally answered.

) If array name arrayName is passed to a function, C automatically passes a) &arrayName[0]+ b) arrayName[1] c) arrayName[0] d) *arrayName
Answers
If array name arrayName is passed to a function, C automatically passes: c) arrayName[0].
The first thing to note is that when arrays are passed as arguments to a function, they are treated as pointers. To pass arrays to functions in C, the array's name should be passed to the function as a pointer. C automatically passes arrayName[0] when array name arrayName is passed to a function. Array elements can be accessed by specifying their index value, which starts with 0 and ends with n-1, where n is the total number of array elements. The first element of the array is arrayName[0]. The &arrayName[0]+0 and *arrayName expressions are also equivalent to arrayName. The address of the first element of the array is returned by &arrayName[0], while the value of the first element is returned by *arrayName. The array's first element can be passed to a function in one of two ways: using the array's name or using the address of the array's first element. The array's first element is equivalent to a pointer. As a result, passing the array's first element to a function is the same as passing a pointer to the array.
As a result, the following code snippets are all equivalent:void fun(int *a);void fun(int a[]);void fun(int a[10]); Here, all the three declarations of fun() are equivalent and refer to the same function.
