Introduction to Microservice Architecture Using SpringBoot - Part 1

How many types of number system are there?

There are four types of number system:

Decimal Number System.
Binary Number System.
Octal Number System.
Hexadecimal Number System.

What are the applications of the octal number system?

The applications of the octal number system are as follows:

For the efficient use of microprocessors.
For the efficient use of digital circuits.
It is used to enter binary data and display of information.

What is a Logic gate?

The basic gates that make up the digital system are called a logic gate. The circuit that can operate on many binary inputs to perform a particular logic function is called an electronic circuit.

What are the basic Logic gates?

There are three basic logic gates

AND gate.
OR gate.
NOT gate.

Which gates are called as Universal gate and what are its advantages?

The Universal gates are NAND and NOR. The advantages of these gates are that they can be used for any logic calculation.

State the De Morgan's Theorem?

1.The complement of a product of two numbers is the sum of the complements of those numbers.

(A. B)' = A' + B'

2. The complement of the sum of two numbers is equal to the product of the complement of two numbers.

(A + B)' = A'B'

What do you mean by Maxterm and Minterm?

A Minterm is known as Product of sum because they are the rational AND of the place of variables and Maxterm is known as the sum of product because they are the rational OR of the place of variables.

What is meant by K-Map or Karnaugh Map?

K-Map is a pictorial representation of truth table in which the map is made up of cells, and each term in this represents the min term or max term of the function. By this method, we can directly minimize the Boolean function without following various steps.

What is Half-Adder?

Half-adder is the circuits that perform the addition of two bits. It has two inputs A and B and two outputs S (sum) and C (carry). It is represented by XOR logic gate and an AND logic gate.

What is Full-Adder?

Full-adder is the circuits that perform the addition of three bits. It has three inputs A, B and a carry bit. Full adders are represented with AND, OR and XOR logic gate.

What is a Multiplexer?

The multiplexer is a digital switch which combines all the digital information from several sources and gives one output.

 

What are the applications of Multiplexer (MUX)?

The applications of the multiplexer are as follows:

It is used as a data selector from many inputs to get one output.
It is used as A/D to D/A Converter.
These are used in the data acquisition system.
These are used in time multiplexing system

Build a 4:1 mux using only 2:1 mux?

What is a Demultiplexer?

The demultiplexer is a circuit that receives the input on a single line and transmits this onto 2n possible output line. A Demultiplexer of 2n outputs has n select lines, which are used to select which output line is to be sent to the input. The demultiplexer is also called as Data Distributor.

What are the applications of Demultiplexer?

The applications of the demultiplexer are as follows:

It is used in the data transmission system with error detection.
It is used as a decoder for the conversion of binary to decimal.
It is used as a serial to parallel converter.

Decoder

Decoder is a combinational circuit that has ‘n’ input lines and maximum of 2n output lines. One of these outputs will be active High based on the combination of inputs present, when the decoder is enabled. That means decoder detects a particular code.

What are the differences between Combinational Circuits and Sequential Circuits?

What is the difference between Latch And Flip-flop?

The difference between latches and Flip-flop is that the latches are level triggered and flip-flops are edge triggered. In latches level triggered means that the output of the latches changes as we change the input and edge triggered means that control signal only changes its state when goes from low to high or high to low.
flip-flops and latches are circuits that have two stable states that can store state information – a bistable multivibrator.

What are the applications of Flip-Flops?

Flip-flops are used as the delay element.
These are used for Data transfer.
Flip-flops are used in Frequency Division and Counting.
Flip-Flops are used as the memory element.

Define edge triggered flip flop?

The difficulty of a contest around the state can be solved by using an edge-triggered flip-flop. The edge-triggered flip-flop will alter its state either at the optimistic edge or unenthusiastic edge of the timepiece pulse. The edge-triggered flip-flop is responsive to its inputs only at this business of a flip-flop.

SR Flip-Flop

SR flip-flop operates with only positive clock transitions or negative clock transitions. Whereas, SR latch operates with enable signal.

D Flip-Flop

  

JK Flip-Flop

 

T Flip-Flop

 

Counters

A special type of sequential circuit used to count the pulse is known as a counter, or a collection of flip flops where the clock signal is applied is known as counters.

There are the following types of counters: Asynchronous Counters Synchronous Counters

What is the difference between Synchronous and Asynchronous Counters?

Define Fan-in and Fan-out?

Fan-in- The Fan-in of the gate means that the number of inputs that are connected to the gate without the degradation of the voltage level of the system.

Fan-out- The Fan-out is the maximum number of same inputs of the same IC family that a gate can drive maintaining its output levels within the specified limits.
