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...]

SIMD and MIMD are the two different types of computer organizations classified by the Michael Flynn based on the number of the data and instruction streams. The major difference between SIMD and MIMD is clear by their names only, the SIMD (Single Instruction Multiple Data Stream) computers can carry out single instruction over multiple data streams. As against, MIMD (Multiple Instruction Multiple Data Stream) computer organization can contain several instructions operating on multiple data … [Read more...]

Decoder and demultiplexer are the combinational logic circuits. The prior difference between decoder and demultiplexer is that the decoder is a device used to decrypt the the input streams from one format into another. On the other hand, the demultiplexer is used to route the information from one input line to any of the multiple output lines. A decoder is considered as a certain case of a demultiplexer. Furthermore, a decoder is demultiplexer without data input stream, and it contains inputs … [Read more...]

CRT and LCD are the types of display devices where CRT is used as conventional display devices whereas LCD is more recent technology. These are mainly differentiated based on the material they are constructed from and working mechanism, however, both are supposed to perform the same function of providing a visual form of electronic media. Here, the crucial operational difference is that the CRT integrates the two processes light generation and light modulation and it is also managed by a single … [Read more...]

Raster scan and random scan are the mechanisms used in displays for rendering the picture of an object on the screen of the monitor. The main difference between raster scan and random scan lies in the drawing of a picture where the raster scan points the electron beam at the entire screen but incorporating just one line at a time in the downward direction. On the other hand, in the random scan, the electron beam is guided on just those regions of the screen where the picture actually … [Read more...]
