Digital Electronics Trivia Questions

Explanation
A register is a group of flip-flops. Flip-flops are sequential logic circuits that store and transfer data in digital systems. They are used to hold and manipulate data, and are essential components in many types of digital circuits and systems. Therefore, a register is a collection of flip-flops that work together to store and transfer data within a digital system.

Explanation
Each flip-flop is a basic memory unit that can store one bit of information. It has two stable states, either 0 or 1, and can hold this value until it is changed. Therefore, the correct answer is 1 bit.

Explanation
A NOR gate is a logic gate that outputs a high signal (ON) only when all of its inputs are low (OFF). If any of the inputs are high (ON), the output will be low (OFF). Therefore, the correct answer is OFF.

Explanation
The correct answer is Intel 4004. The Intel 4004 is widely regarded as the first microprocessor. It was released in 1971 and was a 4-bit microprocessor. The 4004 was revolutionary at the time as it combined the functions of a central processing unit (CPU) onto a single chip, making it the first complete CPU on a single piece of silicon. It paved the way for the development of modern microprocessors and revolutionized the field of computing.

Explanation
The correct answer is 1979. This is the year when the 8088 processor was introduced.

Explanation
The Intel 8080 is a 8-bit microprocessor.

Explanation
The correct answer is Intel because Intel is the company that recently introduced the microprocessors Pentium-I, Pentium-II, Pentium-III, and Pentium-IV. Motorola and Stephen Mors are not relevant to the introduction of these microprocessors.

Explanation
The status register is also known as "Flags" because it contains multiple individual flags that indicate the status or condition of the processor after executing an instruction. These flags provide information about various aspects such as arithmetic operations, logical operations, and control flow. By checking the state of these flags, the program can make decisions or take appropriate actions based on the outcome of previous instructions.

Explanation
The 8085 is based on a 40-pin DIP (Dual Inline Package). DIP is a type of integrated circuit package that has two parallel rows of pins extending from the sides of the package. The number of pins in a DIP package determines the number of connections the integrated circuit has to the outside world. In this case, the 8085 microprocessor has 40 pins, which means it has 40 connections for input/output and power supply.

Explanation
The number system that we use in our day to day life is called the Decimal number system. This system is based on the number 10 and uses ten digits (0-9) to represent all numbers. In the decimal system, each digit's value is determined by its position in the number. It is the most widely used number system and is used in everyday calculations, including counting, measuring, and financial transactions.

Explanation
The three logical operations that are said to be logically complete are AND, OR, and NOT. This means that any Boolean function can be realized using these three operations alone. The AND operation returns true only if both inputs are true. The OR operation returns true if at least one input is true. The NOT operation negates the input, returning true if the input is false and false if the input is true. Together, these three operations provide the necessary tools to represent any Boolean function.

Explanation
A Venn Diagram is a pictorial representation used to illustrate the relationships between different sets of data. In the context of Boolean algebra, a Venn Diagram can be used to visually represent the logical operations and relationships between different sets of Boolean variables or expressions. It consists of overlapping circles or rectangles that represent the sets, and the intersections between them represent the logical operations (such as AND, OR, NOT) between the variables or expressions. Therefore, a Venn Diagram is the correct answer as it is specifically used as a pictorial representation of Boolean algebra.

Explanation
A gate is a device or circuit that performs a specific logic operation on one or more input signals and produces an output signal based on that operation. Once the gate is set, its output will remain unchanged as long as the inputs remain the same. This is because the gate's output is determined solely by the logic operation it performs, and not by any external factors. Therefore, a gate is a device or circuit whose output will remain unchanged once set.

Explanation
An encoder is used for converting one type of number system into another form. It takes input in one format and produces an output in a different format. This can be useful in various applications such as data transmission, signal processing, and communication systems.

Explanation
In a 2nd complement, the number that is subtracted from another number is known as the subtrahend. The subtrahend is the number being subtracted in a subtraction operation. It is the value that is being taken away from the minuend to find the difference. Therefore, in this case, the correct answer is "Subtrahend".
