What is the difference between Internet, Intranet and Extranet?

Updated on 23-Nov-2021 04:44:12
Let us begin by learning about the internet.InternetThe Internet is the biggest network that connects millions of computers worldwide. It is a team of a network including public, private, government, universities, school, and other academic and business networks linked by several technologies including wireless, optical, and electronic.Internet usage is the calculation (defined in bytes, kilobytes, megabytes, or gigabytes) of the amount of data streaming through your computer and the Internet network for a specific time. These data are shared in both directions such as from the Internet network to your device (download), and from your device to the Internet network ... Read More

What is the difference between an IP Camera and CCTV Camera?

Updated on 23-Nov-2021 04:42:42
Let us begin by understanding what an IP Camera is.IP CameraIP camera is a network digital camera that need the Internet Protocol (IP) and has its IP address. An IP camera is used when defining video surveillance cameras.An IP camera uses an Ethernet cable and sends a digital signal. This type of camera can be simply networked and can send a signal to a network video recorder (NVR) placed on a local or remote network.IP cameras tend to capture better quality pictures, which is especially beneficial in the case of transferring targets, as frame rates can be adjusted according to ...

What is the difference between Hardware firewalls and Software Firewalls?

Updated on 22-Nov-2021 05:33:05
Let us understand what a hardware firewall is.Hardware FirewallHardware firewalls are frequently built within the base of broadband routers and are an essential part of a network setup, particularly on a broadband connection. A hardware firewall can be very adequate with minimal or no configuration and can guard each device on the local network. It facilitates packet filtering to test a packet’s header for source and destination analysis, which data is then compared with a group of pre-defined security rules.The packet will be forwarded if it meets the rules or is dropped. Although any user with some computer knowledge can ... Read More

What is the difference between VPN and APN?

Updated on 22-Nov-2021 05:32:06
Let us begin by learning about VPN.VPNVPN stands for the virtual private network. It is an encrypted connection over the web from a device to a network. The encrypted connection supports that sensitive information is safely communicated. It avoids an unauthorized person from eavesdropping on the traffic and enables the user to organize work remotely. VPN technology is broadly used in corporate environments.A VPN protects your IP address by allowing the network to redirect it through a particularly configured remote server run by a VPN host. This defines that if you surf online with a VPN, the VPN server becomes ... Read More

What is Anycast Routing?

Updated on 22-Nov-2021 05:31:17
Anycast is a method for routing network traffic where the sender distributes packets to a destination that is adjacent to it in terms of network topology. The features of Anycasting is that the networking approach can allow for messages to be shared to a team of receivers that all have the similar destination address.The Anycast method is one address and routing methodology compared with others including unicasting. Unicast facilitates a one-to-one connection between a server and a destination address. There are different procedures like multicast and broadcast that send signals from one point to multiple points.Anycasting is ruled by the ... Read More

What is the difference between WEP and WPA?

Updated on 22-Nov-2021 05:30:33
Let us begin by understanding what WEP is.WEPWEP stands for Wired Equivalent Privacy. It is the generally used Wi-Fi security protocol in the world. WEP was produced as a Wi-Fi security requirement in 1999, September.The first form of WEP was not especially strong, even for the time they were launched, because U.S. regulation on the export of several cryptographic technologies led to manufacturers confining their devices to only 64-bit encryption. When the condition was lifted, it was raised to 128-bit. In spite of the introduction of 256-bit WEP, 128-bit remains one of the most common implementations.WEP was destined to support ... Read More

What are Web Pages?

Updated on 22-Nov-2021 05:27:14
A web page is described as a single file or a singular page of any website. Each webpage is connected to a specific URL address used to render or access that specific page. These URLs and web pages can be private or public, based on how the developers have set up them.Some web browsers can be used to operate URLs, which can also be copied and shared by users. Viewing a website does not generally require some navigation if it can have its URL address. However, some URLs are attached to a website that facilitates developers to make a suitable ... Read More

What is the difference between SONET and SDH?

Updated on 22-Nov-2021 05:26:03
Let us understand what Synchronous Optical Networking (SONET) is.SONETSONET stands for Synchronous Optical Networking. It is a standardized digital communication protocol that can transmit a large volume of data over relatively long distances using a fiber optic medium. With SONET, several digital data streams are shared simultaneously over optical fiber using LEDs and laser beams.SONET provides several streams concurrently and supports efficient services in telecommunication systems. It uses standardized line rates, thus all types of organizations can be interconnected using SONET.The network architecture of a SONET depends on transmitting data even if a section of the network has declined. SONET ... Read More

What is ADSL?

Updated on 22-Nov-2021 05:25:03
ADSL represents Asymmetric Digital Subscriber Line. ADSL is a kind of DSL, which is a technique of sharing data over copper mobile lines. While symmetrical DSL (SDSL) transfer and downloads data at a similar speed, ADSL has several maximum data transfer rates for uploading and downloading information.For example, an ADSL connection can enable download costs of 1.5Mbps, while upload speeds can only reach 256Kbps. Because several users download much more data than they upload, this difference generally does not create a noticeable element on Internet access speeds. Still, for Web servers or other computers that send various data upstream, ADSL ... Read More

What is the difference between SONET and DWDM?

Let us understand what Synchronous optical networking (SONET) is.SONETSONET stands for Synchronous optical networking. It is a standardized digital connection protocol that can share a huge volume of data over relatively long distances using a fiber optic medium. In SONET, there are various digital data streams are shared simultaneously over optical fiber utilizing LEDs and laser beams.SONET provides multiple data streams at the same time. It was created to support efficient services in telecommunication systems and thus became widely adopted. SONET uses standardized costs so that all types of organizations can be interconnected.In packet-oriented networks, a single packet normally includes ... Read More
