GPS and GNSS are satellite-based systems globally used to determine positioning, navigation and timing (PNT). GNSS is a broader term that encapsulates different types of global and regional satellite-based navigation systems. GPS is one of the GNSS systems developed by the US. Apart from GPS, GNSS includes three more global satellite-based navigation systems and two regional satellite-based navigation systems. We will discuss each of them in the content below and try to identify every … [Read more...]

VPN and VPS are similar sounding terms, but they are notably different technologies. A virtual private network (VPN) is a service that allows users to stay safe and anonymous online. In contrast, the virtual private server (VPS) is a kind of web hosting technology that divides a physical server into small virtual servers and makes it available to users to host their websites. Although VPN and VPS use virtualization technology, they have been designed to accomplish two totally different tasks. … [Read more...]

4G and 5G are cellular network technology. The technology is used to define mobile networks that allow wireless Internet access. The potential strength of any mobile network is that it connects the user even if he/she is travelling at a higher speed. How Mobile Network Works? Every mobile network has three functional components – Radio Access Network, Core Network and Transport Network. Radio Access Network – It is one to which your mobile phone connects. These are the towers installed … [Read more...]

Raster and vector are two file types we use to store digital images. The basic difference between these two types of digital images is that the raster image is formed using pixels. However, the vector image is formed using a mathematical expression, lines and curves with fixed checkpoints. Rescaling of raster images reduces the quality of the image. However, you can rescale the vector image infinitely without losing the quality of an image. The raster files are larger than the vector … [Read more...]

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...]
