As we know that, for a computer to work properly the two most important components are hardware and software. If either of them is absent, it would not be possible to use the computer system. The hardware is the physical peripheral devices which can be touched and felt and software, programs or group of instruction which are intangible in nature are incorporated to make a computer system. The hardware of a computer could not be easily modified, or we can consider it as fixed, but the software … [Read more...]

RGB and CMYK are the colour models which provides an abstract numeric system for defining the colours with the help of three or four major numbers to show the primary colours. The fundamental difference between RGB and CMYK colour modes is that the number of channels contained by RGB is three. On the contrary, the CMYK model has four component colours. The RGB expands to Red, Green and Blue while CMYK (Cyan, Magenta, Yellow) are the complements of the red, green and blue. Both of the colour … [Read more...]

As the name suggests, serial and parallel are the two types of ports. Serial port and parallel port are mainly differentiated by their implementations where the former is employed when we want to do serial communication. As against, the parallel ports are used when we want to achieve parallel communication. Now, what the serial and parallel communication indicates here. In serial communication, the chunks of the data are sent one after the other. In contrast, in parallel communication, all … [Read more...]

Direct and indirect addressing modes are the different types of addressing modes which specifies the way of accessing the data from the memory while executing the instructions. The prior difference between the direct and indirect addressing mode is that in direct mode the address field refers directly to the memory location at which the data is stored. As against, in the indirect mode, the address field refers to the register first, which is then directed to the memory location. What is an … [Read more...]

The SOP (Sum of Product) and POS (Product of Sum) are the methods for deducing a particular logic function. In other words, these are the ways to represent the deduced reduced logic function. We can use the deduced logic function in designing a logic circuit. The prior difference between the SOP and POS is that the SOP contains the OR of the multiple product terms. Conversely, POS produces a logical expression comprised of the AND of the multiple OR terms. Before understanding SOP and POS, we … [Read more...]

The NC (Numeric Control) and CNC (Computer Numeric Control) are the systems implemented with the various machining tools in the various industries and factories. These Controls mainly differentiated by the fact that NC is the traditional control which allows the use of prerecorded information in the machining process. In contrast, CNC goes one step further by providing more flexibility and capability. CNC's are capable of handling the logical functions. The advancement in technology provided … [Read more...]

The foundation of calculator and computer is the same, and these devices were developed to solve the complicated problems. However, the calculator and computer can be differentiated by the fact that we can program a computer to make decisions while this can't be done with the calculator. The term computer is derived from the word compute, which means . A computer can be considered as a super-fast calculator, but in present the computers handle various tasks such as logical operations, … [Read more...]

We know that for what printers are used for, the main task of a printer is to generate a permanent copy of any output. Here, we are going to discuss about the two types of printers - impact and non-printers. The primary difference between the impact and non-impact printers is that impact printers involves the image produced with the help of electromechanical impact device but in non-impact printers, no mechanical impact device is used. There are several types of printers comes under the above … [Read more...]

The OCR and MICR are the character recognition technologies which convert the printed text into electrical signals and finally into an electronic document. The prior difference between these technologies is that the OCR is used for reading any type of printed text. On the contrary, the MICR is utilized for a more specialized purpose such as in banks to read the cheque information printed in some specific font. The printed material that is scanned by the OCR and MICR differ a lot where the … [Read more...]

On an elementary foundation, computers can be classified into three categories - analog, digital and hybrid computers. These computers can be categorised according to the working principle they follow. For example, analog computers use some certain physical properties such as the electrical and mechanical characteristics for solving or simplifying a problem. On the other hand, digital computers utilize discrete electrical and voltage levels in order to encode a real-life scenario. The computers … [Read more...]
