In a multiprocessing system, when all CPUs are not equal, it is known

SNMP
ASMP
PMNP
TCNP

Correct Answer

A. ASMP

Explanation

In a multiprocessing system, when all CPUs are not equal, it is known as ASMP. ASMP stands for Asymmetric Multiprocessing, which refers to a system where each CPU has a specific role or function. In this type of system, one CPU may be dedicated to handling specific tasks or processes, while others may be responsible for different tasks. This allows for better resource allocation and optimization, as each CPU can focus on its designated workload.

What is the function of a CPU

Does arithmetical and logical functions
Generates control signals for execution of different instructions
Stores data and information
All of the above.

Correct Answer

A. Generates control signals for execution of different instructions

Explanation

The function of a CPU is to generate control signals for the execution of different instructions. This means that the CPU is responsible for coordinating and directing the flow of data and instructions within a computer system. The CPU interprets and executes instructions from the computer's memory, and it generates control signals to ensure that the instructions are carried out correctly. This includes tasks such as fetching instructions, decoding them, executing them, and storing the results. Therefore, the correct answer is that the CPU generates control signals for the execution of different instructions.

These elements can store data in the binary form, its relating to which element in sequential circuit

Hard disk
Microprocessor
Transistor
Flip-flops

Correct Answer

A. Flip-flops

Explanation

Flip-flops are sequential logic elements that can store data in binary form. Unlike other options such as hard disk, microprocessor, and transistor, flip-flops are specifically designed to store and retain data in a sequential circuit. They are commonly used in digital electronic systems to store and control data flow, making them the most suitable option for this question.

The 8085 microprocessor is an Integrated Circuit that consists of ……………….. that helps during the execution of the program.

Flip-flops
Transistors
registers
None of these

Correct Answer

A. registers

Explanation

The 8085 microprocessor is an Integrated Circuit that consists of registers that help during the execution of the program. Registers are small storage units within the microprocessor that hold data temporarily during the execution of instructions. They are used to store operands, intermediate results, and memory addresses. The microprocessor uses these registers to perform various operations and calculations required by the program.

The result after converting binary number (100011)2 to decimal will be

30
43
35
None of these

Correct Answer

A. 35

Explanation

To convert a binary number to decimal, each digit in the binary number is multiplied by 2 raised to the power of its position and then added together. In this case, the binary number (100011)2 has six digits. Starting from the rightmost digit, the first digit is 1, which is multiplied by 2 raised to the power of 0 (2^0 = 1). The second digit is 1, multiplied by 2^1 (2), and so on. Adding all the results together, we get 1 + 2 + 0 + 0 + 1 + 16 = 20. Therefore, the correct answer is 20.

The binary equivalent of (64)10 is

11000000
1100000
1000000
1100010

Correct Answer

A. 1000000

Explanation

The binary equivalent of a decimal number can be found by repeatedly dividing the decimal number by 2 and noting the remainder. In this case, when we divide 64 by 2, we get a quotient of 32 and a remainder of 0. We continue this process until the quotient becomes 0. The remainders in reverse order give us the binary equivalent. In this case, the binary equivalent of 64 is 1000000.

In Boolean algebra, A. A=-----------

A2
A
2A
1

Correct Answer

A. A

Explanation

In Boolean algebra, the expression "A. A" represents the logical AND operation between two instances of variable A. The AND operation returns true only if both operands are true. Since there is only one instance of variable A in the given options, the correct answer is A.
