________is used to hold programs and data for long term use.
Explanation
Secondary memory is used to hold programs and data for long term use. It refers to the storage devices that are external to the computer's main memory, such as hard drives, solid-state drives, and optical discs. Unlike primary memory (RAM), which is volatile and loses its data when the computer is turned off, secondary memory retains data even when the power is turned off. This allows for the storage of large amounts of data and the ability to access it at a later time.Rate this question:

________called machine code, low-level language , in binary form which a particular computer can execute directly.
Correct Answer(s)
Machine LanguageExplanation
Machine language, also known as machine code, refers to the low-level language that is written in binary form and can be executed directly by a specific computer. This language is composed of instructions that the computer's processor can understand and execute without the need for translation or interpretation. It is the most basic form of programming language and is specific to a particular computer architecture.Rate this question:

________icalled machine code, low-level language , in binary form which a particular computer can execute directly.
Correct Answer(s)
Assembly LanguageExplanation
Assembly language is a programming language that is one step above machine code. It uses mnemonic codes to represent the instructions that a particular computer can execute directly. It is considered a low-level language because it provides a more readable and understandable way for humans to write code compared to machine code. Assembly language is then translated into machine code by an assembler, allowing it to be executed directly by the computer.Rate this question:

________ the style or way of programming.
Correct Answer(s)
Programming ParadigmExplanation
The term "Programming Paradigm" refers to the style or way of programming. It encompasses the fundamental principles and concepts that guide the design and implementation of computer programs. Different programming paradigms, such as procedural, object-oriented, functional, and logical, offer distinct approaches to problem-solving and organizing code. The answer correctly identifies "Programming Paradigm" as the term that fits the given description.Rate this question:

________ are errors that occur due to syntax errors
Correct Answer(s)
Compile Time ErrorsExplanation
Compile time errors are errors that occur due to syntax errors in the code. These errors are detected by the compiler during the compilation process. When the code is being compiled, the compiler checks the syntax of the code and if it encounters any errors, it generates compile time errors. These errors prevent the code from being successfully compiled and therefore, the program cannot be executed. Examples of compile time errors include missing semicolons, undeclared variables, and incorrect function calls. These errors need to be fixed before the code can be compiled and run successfully.Rate this question:

Convert the binary number 1101010 to Octal.
Correct Answer(s)
152Explanation
To convert a binary number to octal, we can group the binary digits into sets of three starting from the rightmost digit. In this case, we have 110 101 0. Now, we can convert each set of three digits into its octal equivalent. 110 is equivalent to 6 in octal, 101 is equivalent to 5 in octal, and 0 remains the same in octal. Therefore, the octal representation of the binary number 1101010 is 652.Rate this question:

Convert the Octal Number 7412 to Hexadecimal
Correct Answer(s)
F0AExplanation
To convert the octal number 7412 to hexadecimal, we can first convert it to binary and then to hexadecimal. In octal, each digit represents 3 bits in binary. So, 7 in octal is 111 in binary, 4 is 100, and 1 is 001. Combining these, we get 111100001 in binary. Now, we can group the binary digits into groups of 4 from right to left, giving us 1111 and 0001. Converting these groups to hexadecimal, we get F and 0 respectively. Therefore, the octal number 7412 is equivalent to F0A in hexadecimal.Rate this question:

Convert the decimal number 18.5 to binary.
Correct Answer(s)
10010.1Explanation
To convert a decimal number to binary, we need to divide the number by 2 repeatedly and record the remainders. Starting with 18.5, we divide it by 2 to get 9 with a remainder of 0. We then divide 9 by 2 to get 4 with a remainder of 1. Dividing 4 by 2 gives us 2 with a remainder of 0. Dividing 2 by 2 gives us 1 with a remainder of 0. Finally, dividing 1 by 2 gives us 0 with a remainder of 1. The remainders, read from bottom to top, give us the binary representation 10010. The decimal point remains in the same position, resulting in 10010.1.Rate this question:

Convert the Hexadecimal number B1 to Decimal.
Correct Answer(s)
177Explanation
The question asks for the conversion of the hexadecimal number B1 to decimal. In hexadecimal, B represents the decimal value 11, and 1 represents the decimal value 1. Therefore, when we combine these two values, we get 11*16 + 1*1 = 177 in decimal.Rate this question:
