In python What will be the output of the following code :
print type(type(int))
Correct Answer
B. Type 'type'
Explanation
The code is using the `type()` function to find the type of `int`, which is an integer. The `type()` function returns the type of an object. In this case, the type of `int` is `type`, which represents the type of a class. So the output of the code will be `type 'type'`.
17.
In python What is the output of the following program :
print "Hello World"[::-1]
Correct Answer
A. DlroW olleH
Explanation
The program is using slicing to reverse the string "Hello World". The syntax [::-1] is used to reverse the order of the characters in a string. Therefore, the output of the program is "dlroW olleH".
18.
What is the output of the following program :
print 0.1 + 0.2 == 0.3
Correct Answer
C. False
Explanation
The output of the program is false. This is because when adding 0.1 and 0.2, the result is not exactly equal to 0.3 due to the way floating-point numbers are represented in computers. Floating-point numbers have limited precision, so there can be slight rounding errors. In this case, the result of 0.1 + 0.2 is slightly less than 0.3, hence the comparison is false.
19.

24.
What is used to define a block of code (body of the loop, function, etc.) in Python?
Correct Answer
C. Indentation
Explanation
In Python, a block of code is defined using indentation. This means that the code within a loop, function, or any other block is indented by a specific number of spaces or tabs. This indentation is used to determine the scope of the code and to group statements together. Unlike other programming languages that use curly braces or parenthesis to define blocks of code, Python relies solely on indentation. This helps to improve readability and encourages consistent formatting within the code.
25.
Which of the following is correct?
Correct Answer
D. All of the above
Explanation

30.
What is the output of the following code?
- print(3 >= 3)
Correct Answer
B. True
Explanation
The code is comparing if 3 is greater than or equal to 3 using the >= operator. Since 3 is equal to 3, the comparison is true. Therefore, the output of the code is True.
31.
In CPU, ......... points to the next instruction to be executed.
Correct Answer
B. Program counter
Explanation
The program counter in a CPU is responsible for keeping track of the memory address of the next instruction to be executed. It holds the address of the next instruction in the program sequence, allowing the CPU to fetch the instruction from memory and execute it. The program counter is automatically incremented after each instruction is executed, ensuring that the CPU proceeds to the next instruction in sequence. Therefore, the program counter is the correct answer as it directly points to the next instruction to be executed.

Translator for low level programming language were termed as:
Correct Answer
A. Assembler
Explanation
Assemblers were the translators used for low-level programming languages. They converted assembly code, which is a low-level representation of machine code, into machine code that can be understood and executed by the computer's processor. Assemblers were responsible for translating mnemonic instructions and symbolic labels into their corresponding binary representations. This allowed programmers to write code using more human-readable instructions and labels, making it easier to understand and modify the code.

39.
One GB (Gega Byte) contains --- bytes?
Correct Answer
A. 1073741824
Explanation
One GB (Gega Byte) contains 1073741824 bytes. This is because 1 GB is equal to 1024 MB, and 1 MB is equal to 1024 KB, and 1 KB is equal to 1024 bytes. Therefore, to convert GB to bytes, we multiply 1024 by itself three times (1024 * 1024 * 1024), which equals 1073741824 bytes.
40.
1024 Bytes equivalent to?
Correct Answer
D. 210
Explanation
1024 bytes is equivalent to 210. In computer science, the binary system is used to represent data. In this system, each digit can have two possible values: 0 or 1. Each digit is called a bit, and 8 bits make up 1 byte. Therefore, 210 means that there are 2 to the power of 10, or 1024, bytes.
