Not long before we were talking about sensors. The invention of sensors helps us to solve many mysteries of medical science, manufacturing industries, the world of automotive, and also some other areas too. It was a great discovery of the mankind which helps doctors and scientists around the world to study more about the deadly diseases to develop effective counter solutions.The use of sensors is not only limited to the field of medical research. There are many such examples where sensors are being used to solve some of our huge problems. Let’s see some of the areas where the sensors ... Read More

Earlier we had simple analog watches, then came the trend of digital watches, then the one with pulse check, heart rate and finally the smart watches. So, if you forgot your phone but have your smart watch, it’s OK. You can still receive all your important calls and messages. Anyways here we are not talking about the smartwatches but watches with some extra smartness. Confused?So let’s put it this way, imagine a watch that would use your hand as an interface. Your hand will be your ultimate watch, cool right? You interact with this interfaces outside the smartwatch. This is ... Read More

In a computer system, a port provides an interface to connect a peripheral device to the computer system. Thus, ports in the computer hardware are the jacks or sockets through which the peripheral devices are attached to the computer system. These ports are standardized for each purpose. There are several types of ports available in the computer system such as USB ports, Ethernet ports, display ports, serial ports, parallel ports, etc. Through these ports, we connect different hardware devices such as monitor, keyboard, mouse, etc. to the computer. Read through this article to find out more about Serial ... Read More

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

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 ...
