A printer is an output device that produces information or computer outputs on a paper. Depending upon the technology used, printers are classified into two categories namely, Impact Printers and Non-Impact Printers. An impact printer is one that operates by striking a printing head (made up of metal or plastic) against an ink ribbon, whereas a non-impact printer is one that prints characters and graphics without direct physical contact between the printing head and the paper. Read this tutorial to find out more about Impact and Non-impact Printers and how they are different from each other. What is an Impact ... Read More

A projector is a visual display unit that is used to project pictures and films onto a screen. Depending on the technology used, several types of projectors available such as LCD projector, LED projector, DLP projector, 4K Projector, Laser projector, etc. In this article, we will discuss about DLP and LCD projectors, and how they are different from each other. The basic difference between the two is that DLP projectors use a series of mirrors placed on a microchip that act as pixels, whereas LCD projectors use liquid crystals placed between two transparent electrodes and two polarizing filters. What is ... Read More

Both decoder and demultiplexer are types combinational logic circuits used for implementing different types of digital systems. However, the function of a decoder is completely different from that of a demultiplexer. A decoder is a combination logic circuit that decrypts an input data stream from one format to another, whereas a demultiplexer is a combination circuit that routes the data from one input line to any of the multiple output lines. Read this article to find out more about decoders and demultiplexers and how they are different from each other. Let's start with a basic overview of these two combinational ... Read More

The reflected binary code or Gray code is an ordering of the binary numeral system such that two successive values differ in only one bit (binary digit). Gray codes are very useful in the normal sequence of binary numbers generated by the hardware that may cause an error or ambiguity during the transition from one number to the next. So, the Gray code can eliminate this problem easily since only one bit changes its value during any transition between two numbers.Conversion of Gray to Binary CodeGray codes are used in rotary and optical encoders, Karnaugh maps, and error detection. The ... Read More

This cyclic variable code ... Read More

The excess-3 code (or XS3) is a non-weighted code used to express code used to express decimal numbers. It is a self-complementary binary coded decimal (BCD) code and numerical system which has biased representation. It is particularly significant for arithmetic operations as it overcomes shortcoming encountered while using 8421 BCD code to add two decimal digits whose sum exceeds 9. Excess-3 arithmetic uses different algorithm than normal non-biased BCD or binary positional number system.Representation of Excess-3 CodeExcess-3 codes are unweighted and can be obtained by adding 3 to each decimal digit then it can be represented by using 4 bit ...

Digital Computers use Binary number system to represent all types of information inside the computers. Alphanumeric characters are represented using binary bits (i.e., 0 and 1). Digital representations are easier to design, storage is easy, accuracy and precision are greater.There are various types of number representation techniques for digital number representation, for example: Binary number system, octal number system, decimal number system, and hexadecimal number system etc. But Binary number system is most relevant and popular for representing numbers in digital computer system.Storing Real NumberThese are structures as following below −There are two major approaches to store real numbers (i.e., ...

Complements are used in digital computers in order to simply the subtraction operation and for the logical manipulations. For the Binary number (base-2) system, there are two types of complements: 1’s complement and 2’s complement.1’s Complement of a Binary NumberThere is a simple algorithm to convert a binary number into 1’s complement. To get 1’s complement of a binary number, simply invert the given number.2’s Complement of a Binary NumberThere is a simple algorithm to convert a binary number into 2’s complement. To get 2’s complement of a binary number, simply invert the given number and add 1 to the ... Read More

Binary Number System is one the type of most popular Number Representation techniques that used in digital systems. In the Binary System, there are only two symbols or possible digit values, i.e., 0 (off) and 1 (on). Represented by any device that only 2 operating states or possible conditions. Generally, there are two types of complement of Binary number: 1's complement and 2’s complement. To get 1’s complement of a binary number, simply invert the given number. For example, 1’s complement of binary number 110010 is 001101. To get 2’s complement of binary number is 1’s complement of given number ... Read More
