The FPGA and CPLD devices were developed with the intent of achieving the circuit density and speed like ASIC (Application Specific Integrated Circuit) but with a smaller turn around time for the programmable devices. The main difference between the FPGA and CPLD is that FPGA provides extensive logic resources as compared to the CPLD, which is simple and contain less number of interconnections. For segregating the FPGA and CPLD, mainly two things are considered. First, is their architecture … [Read more...]
Difference Between TDMA and CDMA
The designing and standardizing of the cellular systems involve the selection of the multiple access method. Basically, there are three types of multiple access schemes that are TDMA, FDMA and CDMA. In this article, we are going to differentiate between TDMA and CDMA. The significant difference between TDMA and CDMA is that TDMA permits the user to share the channel based on the time slots whereas CDMA distribute the channel by code. All this is related to the signal multiplexing, in which … [Read more...]
Difference Between Interface and Inheritance
Interfaces used to enable several distinct classes to share a probable group of properties and methods. The Interface is useful for abstracting a class where it specifies the operation performed by the class but does not reveal the background working or how it is going to do it. While inheritance assists the creation of specialized subclasses by base class and this is helpful in reusing the code. More generally inheritance is used to extend the class functionality. However, both are the … [Read more...]
Difference Between Multimode and Single-mode Fiber
You might be having an idea about optical fiber, or you can refer previously written article on the difference between optical fibre and coaxial cable. The multimode and single-mode are the types of the optical fiber cable. These fiber optics cable variants can be differentiated by the way in which light is transmitted through these fibers. The prior difference between multimode and single-mode fiber is that the diameter of core and cladding in multimode fiber lies in the range of 50-85 μm … [Read more...]
Difference Between SOAP and REST
Web services are categorised into two types: SOAP and REST. Typically SOAP and REST are the methods used to call the web services. There are several differences between SOAP and REST. Firstly SOAP relies on XML to assist the services while REST can support various formats such as HTML, XML, JSON, etc. Another significant difference is that SOAP is a protocol. Conversely, REST is considered to be an architecture, which means that REST is a platform that uses existing protocols for the client and … [Read more...]
Difference Between Radio wave and Microwave
The radio waves and microwaves are the kinds of electromagnetic waves. Now before understanding the two in detail, we must know its background details such as what are electromagnetic waves and how these can be produced. The electromagnetic waves radiated by accelerating charges. The electric and magnetic fields oscillate simultaneously which result in regeneration of both of the fields. In simple words, the oscillating electric and magnetic fields reproduce each other and the wave is propagated … [Read more...]
Difference Between Prim’s and Kruskal’s Algorithm
Prim's and Kruskal's algorithms are designed for finding the minimum spanning tree of a graph. These algorithms use a different approach to solve the same problem. Prim's algorithm works by selecting the root vertex in the beginning and then spanning from vertex to vertex adjacently, while in Kruskal's algorithm the lowest cost edges which do not form any cycle are selected for generating the MST. These algorithms are designed for the undirected graph. The Minimum Spanning Tree (MST) is a … [Read more...]
Difference Between Greedy Method and Dynamic Programming
To solve the optimization problem in computing the two methods namely greedy and dynamic programming are used. The solutions produced by the greedy algorithms are more effective than the dynamic programming solutions. The primary difference between the greedy method and dynamic programming is that greedy method just generates only one decision sequence. As against, dynamic programming can produce many decision sequences. Content: Greedy Method Vs Dynamic Programming Comparison … [Read more...]
Difference Between QAM and QPSK
The primitive difference between the QAM and QPSK is that the spectral width of QAM is narrower than the QPSK. Furthermore, the BER (Bit Error Rate) of the QAM is higher than the QPSK. Previously, to transfer the digital data we used analog transmission medium. Hence, we required a technology which can convert the digital data into analog signals, such as employed in the telephone networks. So, to perform such task the modem (modulator/demodulator) is used where the modulation and demodulation … [Read more...]
Difference Between SONET and SDH
SONET and SDH are the interfacing optical technologies mainly used in telephone networks. These technologies are very similar; however, there exist minor differences between them. The first point based on which SONET and SDH can be distinguished is the origin of the standards SONET is developed by ANSI and can carry payloads for the North American PDH hierarchy. On the other hand, SDH was developed by ITU-T (international standard). Furthermore, the frame format of SONET usually utilizes v3 … [Read more...]
