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...]

DLP and LCD are the types of DVP (Digital Video Projection) technologies used for displaying the computer screen over a large LCD screen or wall. The main difference between DLP and LCD projector is that the DLP works as a reflective technology while LCD is a transmissive method. Furthermore, DLP is more latest technology as compared to LCD. Content: DLP Projector Vs LCD Projector Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

Interlaced and progressive are the raster scanning technique widely used in analog video system. These techniques are distinguished according to the scanning process where the interlaced scan employs the scanning of odd and even marked lines of a picture that are displayed consecutively as two isolated fields which are superimposed to generate one frame or picture on the screen. On the other hand, progressive scanning sweep over the whole image at a time. Content: Interlaced Scan Vs Progressive … [Read more...]

Multiprocessor and multicomputer are types of parallel computers. The fundamental difference between them is that a multiprocessor is a solitary computer containing several processors interconnected with the common computing resources such as memory and I/O devices. On the contrary, the multicomputer is constructed by interconnecting multiple autonomous computers through a network and each autonomous system has its own computing resource. Content: Multiprocessor Vs Multicomputer … [Read more...]
