i. There are five attributes in the above table: Admno, Name, Subject, Sex, and Average.

ii. There are two tuples in the above table, one for each student.

iii. The degree of the table is 5, which is the number of attributes.

iv. The cardinality of the table is 2, which is the number of tuples.

Note that the table provided contains information on two students, and has five attributes: Admno, Name, Subject, Sex, and Average. The Admno attribute is a unique identifier for each student.

There are two tuples in the table, one for each student. The degree of the table is 5, which means it has five attributes. The cardinality of the table is 2, which means it has two tuples.

Note that:

Attributes: Characteristics or properties of an entity or object that are stored in a database table as columns.

Tuples: A row or record in a database table that contains a set of related attributes or fields.

Cardinality: The number of tuples or rows in a database table, also known as the size or count of the table.

An interest-only loan's monthly installments are calculated using our straightforward interest calculator.

With a mortgage calculator, you pay back a portion of the principal each month, which causes your loan total to decrease over time. This is how you can tell the difference between "only" interest and a mortgage payment.

Only the interest is paid using the straightforward interest calculator. The loan balance is fixed for all time. We didn't add a field to indicate how long your loan will be because nothing changes over time.

Simple interest can be applied to both lending and borrowing situations. In the first scenario, interest is monthly added to a different fund.

Therefore, An interest-only loan's monthly installments are calculated using our straightforward interest calculator.

The problem is with the platform. The fact that the software ran well on an iPhone but not on Windows suggests that the problem is with the platform (i.e., the operating system and hardware) rather than with mobile devices in general.

An operating system is a piece of software that handles the hardware of a computer and serves as a platform for other applications to run on.

Hardware refers to the physical components or delivery systems of a computer that store and execute the textual instructions delivered by software. The software is the device's intangible component that allows the user to communicate with the hardware and direct it to do specified tasks.

The output of the above-given code is: 34 (Option C)

Here's how the code works:

whoknows(34, 55) returns 55, because b is greater than a.

whoknows(55, 44) returns 55, because b is less than a.

Finally, console.log(34) outputs 34, because 34 is the result of the previous function calls passed as arguments.

The above code defines a JavaScript function named "whoknows" that takes two parameters "a" and "b". The function then assigns the value of "a" to a variable named "sec" and checks if "sec" is less than "b". If it is, then the function sets "sec" to the value of "b". Finally, the function returns the value of "sec".

The code also includes a call to the "whoknows" function inside a console.log statement, passing in the values 34, 55, and 44 as arguments.

Answer:

It could become extinct.

Explanation:

The code will have a syntax error on line 3

The code has a syntax error on line 3 as there is an assignment operator instead of a comparison operator in the while loop condition. It should be 'while (k < 4)' instead of 'while (k = 4)' to check if the value of 'k' is less than 4.

Assuming this syntax error is corrected, the output of the code will be 1. This is because the loop will iterate four times, adding 1 to the 'sum' variable each time, resulting in a total of 4. However, the 'sum' variable is not printed to the console, and the 'write' function on line 8 is undefined, so nothing will be output to the console.

Answer:

Here is the pseudocode for the given problem:

Get the codeWord from the user input.

Initialize an empty string newCodeWord.

For each character c in codeWord do the following:

a. If c is an alphabetic character or a number, append it to newCodeWord.

b. Else, append 'z' to newCodeWord.

Update the value of codeWord to be equal to newCodeWord.

Output the message "Valid password: " followed by the updated value of codeWord.

Here is the pseudocode in code format:

string codeWord, newCodeWord = "";

int i;

cin >> codeWord;

for (i = 0; i < codeWord.length(); i++) {

   if (isalnum(codeWord[i])) { // check if the character is alphabetic or a number

       newCodeWord += codeWord[i];

   }

   else {

       newCodeWord += 'z';

   }

}

codeWord = newCodeWord;

cout << "Valid password: " << codeWord << endl;

Explanation:

Note that isalnum() is a standard library function in C++ that returns true if the character passed to it is alphabetic or a number.

Answer:

ii) Sampling resolution is the number of bits used to represent each sample of the analog sound wave. Higher sampling resolution means that each sample can be represented with more bits, which results in a more accurate representation of the original sound. This is because higher resolution provides more levels of amplitude that can be represented, resulting in a more faithful reproduction of the original sound wave.

b)

i) The number of bits required to encode data for one pixel of a 16-color bitmap image is 4 bits.

ii) The size of the image file can be calculated as follows:

Number of pixels in the image = 16384 x 512 = 8388608

Number of bits required to encode one pixel in a 256-color bitmap image = 8 bits

Total number of bits required to encode the image = 8388608 x 8 = 67108864 bits

Convert bits to gibibytes:

1 gibibyte = 2^30 bytes

1 byte = 8 bits

Therefore,

67108864 bits = 8388608 bytes = 8.192 megabytes (MB)

1 MB = 2^20 bytes = 0.0009765625 gibibytes

Therefore,

8.192 MB = 0.0078125 gibibytes

Hence, the size of the image file is approximately 0.0078125 gibibytes.

Answer:

The Central Processing Unit (CPU) is an essential component of a computer that performs all arithmetic, logical, input/output (I/O), and control operations. The CPU consists of three primary components: the control unit, the arithmetic logic unit, and registers.

Control Unit (CU):

The Control Unit (CU) is responsible for controlling the flow of instructions in the computer system. It receives instructions from memory and decodes them, determining which operations to perform and in what order. It also controls the input/output operations of the computer system.

Arithmetic Logic Unit (ALU):

The Arithmetic Logic Unit (ALU) is responsible for performing arithmetic and logical operations in the CPU. It performs basic arithmetic operations such as addition, subtraction, multiplication, and division. It also performs logical operations such as AND, OR, NOT, and XOR.

Registers:

Registers are small, high-speed storage locations within the CPU that hold data and instructions. They are used to temporarily hold data and instructions that are frequently accessed by the CPU, allowing the CPU to access them quickly.

Below is a simplified diagram of a CPU with its major components:

The FROM portion of the SQL SELECT statement is written first

For managing data stored in a relational database management system or for stream processing in a relational data stream management system, programmers utilize the domain-specific language known as SQL, sometimes known as Structured Query Language.

A database table's records are retrieved using a SQL SELECT statement in accordance with clauses (such FROM and WHERE) that define criteria. As for the syntax: the following query: SELECT column1, column2 FROM table1, table2 WHERE column2='value';

Explanation:

In this code, we first calculate the sum and average of the input numbers by iterating over the ArrayList. We then calculate the frequency of each number using a HashMap, and keep track of the maximum frequency. We then iterate over the HashMap to check if there is a single mode or not. If there is, we print the mode; otherwise, we print "no single mode". Finally, we print the sum and average.
