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...]

The prior difference between the holography and photography is that holography intends to form three-dimensional images while the photography generally generates two-dimensional images of a three-dimensional object. However, the creation of the images in both of the techniques is different where holography uses the interference of light between the reference beam and light reflected from the object. On the other hand, the photography makes use of photographic film on which the light gets … [Read more...]

Mainframe and minicomputers are the types of a computer where mainframe computers provide much more features than minicomputer and high capacity for memory and processing speed. Initially, mainframes were constructed to provide reliability for transaction processing and are mainly utilized as servers. On the other hand, minicomputers are mid-size, small computers which people can use personally or as a high-end device too. However, this classification is based on the size and storage capacity … [Read more...]

Blu-ray and DVD are the types of optical memory where blu-ray provides larger space for storing HD videos while DVD offers less space. Blu-ray is earlier technology and the primary motive to devise it is to provide a more efficient and superior technology that is compatible with newer tech. Back in earlier days, we used LDTV and VCD then with the advancement in the technology, enhanced televisions with larger screens were developed from CRT to LCD and LED. This lead the development of SDTV, … [Read more...]
