Fundamentals Of Digital Electronics 3

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.

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.

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 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.

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.

The hexadecimal equivalent of the decimal number 72 is 48.

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.

DVD stands for Digital Versatile Disc. This is the correct answer because DVD is a type of optical disc storage media that can be used for various purposes, such as storing and playing back audio, video, and data. The term "versatile" refers to its ability to handle different types of content and formats. The other options, Digital Video Disc and Digital Virtual Disc, are not correct because they do not accurately represent the acronym DVD.

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.
