Digital Electronics Trivia Questions

2.

Each Flip-flop stores ---------- bits

1 bit
8 bit
16 bit
2 bit

Correct Answer

A. 1 bit

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.

A NOR gate is ON only when all its inputs are

ON
Positive
High
OFF

Correct Answer

A. OFF

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.

The First Microprocessor was__________

Intel 4004
8080
8085
4008

Correct Answer

A. Intel 4004

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.

Pentium-I, Pentium-II, Pentium-III and Pentium-IV are recently introduced microprocessor by__________

Motorola
Intel
Stephen Mors
None of these

Correct Answer

A. Intel

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.

8.

Status register is also called as ___________

Accumulator
Stack
Counter
Flags

Correct Answer

A. Flags

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.

The 8085 is based in a _____ pin DIP

40
45
35
20

Correct Answer

A. 40

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.

The number system that we use in our day to day life is called the Number System__________

Octal
Binary
Hexadecimal
Decimal

Correct Answer

A. Decimal

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.

The three logical operations, which are said to be logically Complete, as any Boolean function may be realized using these Three operations are:

AND, OR and NOT
AND, OR and XOR
AND, OR and NAND
XOR, NOR and NAND

Correct Answer

A. AND, OR and NOT

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.

Pictorial representation of Boolean algebra is known as

Venn Diagram
Flow Chart
Data Flow Diagram
Truth Table

Correct Answer

A. Venn Diagram

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.

Device or Circuit whose output will remain unchanged once set

Flip-Flop
Gate
Boolean Algebra

Correct Answer

A. Gate

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.

……….Are used for converting one type of number system in to other form

Encoder
Logic gate
Half adder
FA

Correct Answer

A. Encoder

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.

In a 2nd complement a number which is subtracted from other number is known as………..

Carry
Subtrahend
Minuend
None of these

Correct Answer

A. Subtrahend

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".
