The RTP protocol allows the transfer of the application with real-time properties such as security, lost detection, content identification and timing reconstruction etcetera. While the RTCP transports statistics for a media connection and information such as the number of packets transmitted, packet loss, packet delay, delay variation, etcetera. The main difference between the RTP and RTCP is that the RTP just offers a way to transfer the real-time traffic through a network while RTCP ensures … [Read more...]

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...]

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...]

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...]

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...]

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...]

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...]

CIDR and VLSM are the terms explicitly used at the time of designing a network where CIDR is used for merging the routes in order to decrease the routing information carried by the core routers. On the contrary, VLSM facilitates in optimizing the available address space. CIDR is just opposite of VLSM, where it describes rules for referencing set of networks with a single route statement. Conversely, VLSM defines rules for subdividing the networks. Content: CIDR and VLSM Comparison … [Read more...]

Cloud computing and virtualization are very closely related terms where the virtualization drives single resource behaves as many whereas cloud computing enables distinct departments and companies retrieve a single pool of spontaneously provisioned resources. Virtualization is the primary technology used to make the cloud computing functional. However, it is different from cloud computing which we have described below in detail. Content: Cloud Computing Vs Virtualization Comparison … [Read more...]

A router and firewall are two different things, and the router is hardware to provide connections to various devices. As against, a firewall resides between the network and the system to filter the data going in and out of the system. However, both can be used for filtering the traffic with an access control list. The router works on a hardware level, mostly. In contrast, the firewall is based on software. The router is a device used for establishing the networks. Inversely, a firewall is … [Read more...]
