NGN stands for Next Generation Network. It defines the evolution and migration of hooked and mobile network frameworks from distinct proprietary networks to assemble networks depending on IP. It is accepted to be an interworking environment of heterogeneous networks of wired and wireless access networks, PSTN, satellites, transmission, etc.Next-generation networks are used to send all types of services and data such as voice data/calls, audio data/calls, and multimedia data including videos. All types of such data are encapsulated in data packet design.An NGN is simply based on Internet technology, such as MPLS and IP. It uses H.323 protocol as its ... Read More

Let us understand what a digital video recorder DVR is.DVRDVR stands for Digital Video Recorder. It is a recording device that records video in a digital structure and saves it on hard drives instead of videotapes. It needed video signals to be digitized and compressed to save as many days’ worth of video feed as available.Security systems using DVRs play an important role in alarm verification and security assessment. The digital video images are saved on hard disks similar to those used in the PCs and have storage areas calculated in gigabytes. It provides a cheap but efficient technique for ... Read More

Gigabit Ethernet is a variant of the Ethernet technology generally used in local area networks (LANs) for sending Ethernet frames at 1 Gbps. It can be used as a backbone in several networks, especially those of large organizations.Gigabit Ethernet is an enlargement to the earlier 10 Mbps and 100 Mbps 802.3 Ethernet standards. It provides 1, 000 Mbps bandwidth while supporting full compatibility with the set up base of around 100 million Ethernet nodes.Gigabit Ethernet usually employs an optical fibre connection to share records at a very huge speed over high distances. For short distances, copper cables and twisted pair ... Read More

Let us understand what a campus area network (CAN) is.CANCAN stands for campus area network. It is a network of several interconnected local area networks (LAN) in a finite geographical location. It is smaller than a wide area network (WAN) or metropolitan area network (MAN).In CAN, the same technology along with the hardware is used in multiple buildings of one campus or one association. They follow similar terminologies such as the local area networks but the change is that they are interconnected between the several buildings at the specific location.Campus Area networks are cost-effective, beneficial, and simple to implement in ...

Let us begin by understanding what McAfee is.McAfeeMcAfee is the most used antivirus solution provider and has been in use because of the first advertise of viruses. McAfee supports a complete range of security products including antivirus, firewall, and anti-spyware programs. McAfee Antivirus occurs with a set of features that will maintain your computer free of viruses, worms, Trojans, and several malicious codes.McAfee also merges a restrained full-screen feature, which stops all antivirus notifications from being advertised while full-screen applications are running, so it won't prevent your work.The Secure File Shredder feature is another helpful feature, which will enable you ...

Let us first understand what an electronic signature is.Electronic SignatureAn electronic signature is a method of defining your signature on a computerized document such as a delivery slip. The electronic signature can define multiple techniques of securing a signature on a document or device.This contains methods including using a tablet or mobile application to capture an image of a handwritten signature. It can also be easily typing your name into a signature box. An instance of a frequently produced electronic signature is when it is sign for a delivery on the courier’s digital tool.The characteristic of an electronic signature is ... Read More

Optical fibre is a hair-thin glass or plastic fibre with a frequent diameter of 125 micrometers (μm), which is known as the cladding, or outer reflecting layer. The core or inner transmitting route is generally as small as 10μm.This channel enables the transmission of data as light pulses rather than electrical pulses. This process is referred to as total internal reflection, where light rays transmitted into the fibre travel and reflect inside the core for high distances with very little attenuation while supporting its intensity.Advantages of Fibre Optic CableThe advantages of fibre optic cable are as follows −Speed − The ...

First, let us learn about Wavelength Division Multiplexing (WDM).WDMWDM represents Wavelength Division Multiplexing. WDM is completed only in fibre optic channels. In WDM, there are several light waves from several sources are linked utilizing a prism to make a composite light signal transmitted across the channel.The application of WDM is the SONET network in which several optical fibre lines are multiplexed and demultiplexed. There is a new technique referred to as DWDM (dense WDDM). It can create multiple huge computers of the medium by composing mediums closer to one another. It achieves even higher efficiency.Types of WDMThere are two types ... Read More

In 10 Gigabit Ethernet, it is a telecommunications technology that sends data packets over Ethernet for 10 billion bits per second. This innovation improved the traditional and well-known use of Ethernet in the local area network (LAN) to a much wider area of network application, such as high-speed storage area networks (SAN), wide area networks (WAN), and metropolitan area networks (MAN).10 GbE differs from traditional Ethernet in that it takes benefit of full-duplex protocol, in which data is sent in both directions simultaneously by utilizing a networking switch to link devices.This defines that the technology diverges from the Carrier Sense ...
