[#1121] Multiplication of 111 2 by 101 2 is
Correct Answer

(B) 100011 2

Explanation

Solution: Multiplication of 111 2 by 101 2 is 100011 2 7 = 111 5 = 101 So simple 5 × 7 = 35 Now it will be converting in binary 32 16 8 4 2 1 1 0 0 0 1 1 35 = 100011 2 The same technique will be used if large no occur.

[#1122] Which of the following registers is used to keep track of address of the memory location where the next instruction is located?
Correct Answer

(D) Program Counter

Explanation

Solution: A program counter is used to keep track of the execution of the program. It contains the memory address of the next instruction to be fetched.

[#1123] Which is not a factor when categorizing a computer?
Correct Answer

Speed of the output device

Explanation

Solution: It was purchased is not a factor when categorized a computer. Computers can be classified, or typed, in many ways. Some common classifications of digital computers are summarized below. For others see Category: Classes of computers.

[#1124] Conversion of an octal number 20 8 to its binary number is
Correct Answer

(A) 10000 2

Explanation

Solution: Conversion of an octal number 20 8 to its binary number is 10000 2 . 20 to base 8 convert into decimals as 0 × 8 0 + 2 × 8 1 = 0 + 16 = 16. From decimal convert to binary, i.e. $$frac{{16}}{2}$$ = 8 remainder 0. $$frac{8}{2}$$ = 4 remainder 0. $$frac{4}{2}$$ = 2 remainder 0. $$frac{2}{2}$$ = 1 remainder 0. So the answer is 10000 2

[#1125] Which of the following is a system programming language for micro-computers in the Intel family.
Correct Answer

LOGO

Explanation

Solution: This question asks you to identify a programming language specifically designed for creating system software (like operating systems or drivers) on computers using Intel processors. Let's look at each option: Option A: LOGO: LOGO is an educational programming language, not typically used for system programming. Option B: SNOBOL: SNOBOL is a string processing language, not primarily used for system-level programming. Option C: PCM: PCM (Pulse Code Modulation) is a method for digitally representing analog signals, not a programming language. Option D: PL/1: PL/1 is a general-purpose programming language, but it's not commonly associated with microcomputer system programming in the Intel family. Therefore, none of the given options are widely known system programming languages for Intel microcomputers. The correct answer is likely a language like Assembly language or C , which are commonly used for this purpose but not listed here. The best answer is E: None of the above.
