JPEG and TIFF are two common types of file formats that we use for storing images. JPEG and TIFF images are raster images defined using pixels with one or more associated numbers. The value of these numbers decides the location, colour, or size of the pixel in the particular image. Almost all the images you see on the web or captured using digital cameras are raster images. Being raster images, the image in JPEG format differs from the image in TIFF format in the way they compress … [Read more...]

Intranet and extranet are derived from a global network that we refer to as the Internet. An intranet is a private network established inside an organisation to let all employees communicate and share resources. However, an extranet is a private network that authenticated users outside the organisation can access via a network password. The users inside the organisation only use the intranet. However, the users inside and the authorised users outside the organisation use the extranet. This … [Read more...]

URL and IP address are identifiers; URL points to the address of a particular web page on the world wide web; however, an IP address points to a specific device connected to the Internet. URL includes the protocol, the domain name, and the path indicating a particular web page. The IP address includes the network part and the host part. The network part specifies the network to which the device belongs. The host part of the IP address identifies the particular device of that network. In … [Read more...]

Internet and Ethernet both are the communication standards that enable connectivity between the communicating devices. Internet is a network of networks that gradually forms a wide area network (WAN). Meanwhile, Ethernet is a hardwired connection between the computers that gradually forms a local area network (LAN). The Internet is a global network connecting users across the world. However, Ethernet is used to connect your device to the local area network. Although you can even use Ethernet … [Read more...]

Modulation and demodulation are the techniques important for establishing communication between the devices. Modulation superimposes a weak signal (information) onto a strong carrier signal to get a modulated signal. The modulated signal is further transmitted over a longer distance. Demodulation processes the modulated signal to retrieve the original information. Modulation and demodulation are complementary processes to each other. Thus, modulation is being conducted at the senders’ side … [Read more...]

VPN and DNS are the tools that let you access the geo-blocked contents. Although their basic work is different. The VPN provides secure communication between your device and the Internet. On the other hand, the DNS resolves the name of a remote host to its IP address. Initially, we will discuss the differences between VPN and DNS with the help of the comparison. Further, we will discuss the terms VPN and DNS in detail along with the related queries. Content: VPN Vs DNS Comparison … [Read more...]

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...]
