How Does the Access-Control-Allow-Origin Header Work?
In this tutorial, we will learn how access control allows the origin header to work. Access-Control-Allow- Origin is a header for CORS. With CORS or cross-origin resource sharing, browsers can permit a website hosted at origin A to request resources from origin B. Origin is a mix of port, hostname, and scheme, such as http://tutorialspoint.example.com:5000/, rather than just the hostname. Here is an illustration of how this is put into practice − I want to obtain resources from origin B, which is http://yoursite.com, and origin A:https://www.tutorialspoint.com. ...
Read MoreDifference Between Web page and Website
Web page and website are related terms and sometimes people tend to use them interchangeably, but they are distinct from each other. The basic difference between a web page and a website is that a web page is a text document written in HTML (Hyper Text Markup Language) and is rendered by a web browser, whereas a website is a collection of related webpages having a specific address, called URL, on the Internet. This article is meant for explaining the important differences between web page and website. But, before going into the differences, let's have a basic overview of what ...
Read MoreDifference Between HTTP and HTTPS
Have you ever seen http:// or https:// in a browser's address bar while surfing a website? In a nutshell, both of these are protocols that allow a web server and a web browser to communicate about a certain website. But, what are the features that distinguish these two? Well, the most important difference between "http" and "https" is that "https" is far more secure than "http". Read through this article to find out more about "http" and "https" and how exactly they are different from each other. The protocol used to send hypertext over the Web is called the HyperText ...
Read MoreWhat is HTTP Flooding? (Process, Types, How to Detect and Defend)
What is HTTP Flooding?HTTP flood is a sort of Distributed Denial of Service (DDoS) attack in which an attacker attacks a web server or application using seemingly valid HTTP GET or POST requests.HTTP flood assaults are volumetric attacks that frequently employ a botnet "zombie army"—a collection of Internet-connected computers that have been maliciously taken over, usually with the help of malware such as Trojan Horses.HTTP floods are a sophisticated Layer 7 assault that does not involve corrupted packets, spoofing, or reflection techniques and requires less bandwidth to bring down the targeted site or server than other attacks. As a result, ...
Read MoreWhat are the differences between Physical and Logical Topology?
The network topology is a structure or the physical arrangement of the network devices, how the components of the network are interconnected with each other.Types of network topology are as followsBusStarRingMeshHybridLogical TopologyIt tells about a network that should be configured for the transfer of information. This is different from physical topology as it does not explain the physical wiring of a network, but instead, it describes the flow of data, information, and back, from one system to another and the routes it takes.Some examples of Logical topology are as follows −Logical Star Topology − Uses logical bus topology to transfer ...
Read MoreWhat is Adaptive Internet Protocol (AIP)?
Internet protocols are the set of rules of a network so that a packet of data travels across the network. Data travels over the networks in the packet. Domain for this transportation of the data is called the IP address. Most of the protocols used for this are TCP and UDP.Now let us discuss one of the protocols which allow running multiple platforms, that is AIP. The full form of AIP is Adaptive Internet Protocol.Adaptive Internet Protocol (AIP)It is a multichannel protocol used to allow an application which is running on multiple platforms, displayed on any number of client systems.AIP ...
Read MoreWhat are the differences between EIGRP and BGP?
Let us understand the concepts of Enhanced Interior Gateway Routing Protocol (EIGRP) and Border Gateway Protocol (BGP) before learning the differences between them.Enhanced Interior Gateway Routing Protocol (EIGRP)It is the enhanced version of IGRP protocol. It consists of all the features which IGRP does and also supports some ad-on's.To overcome the drawbacks of IGRP i.e like slow rate of convergence, hop limitation, no support to VLSM etc and IGRP is the successor of RIP which removes the hurdles caused by RIP routing technique.We all know that IGRP works or supports many protocols other than IP unlike RIP. The same fashion ...
Read MoreWhat are the differences between DTE and DCE?
Let us understand the concepts of Data Terminal Equipment (DTE) and Data Communications Equipment (DCE) before learning the differences between them.Data Terminal Equipment (DTE)At the physical layer, the function of DTE is to look for clocking from the device on the other end of the cable on a link and look for a frame-switching service.The device receives clocking. The customer devices or the DTE pass data from a host computer on a customer network for transmission over the Wide Area Network (WAN).Also, its function is to convert user information into signals or reconvert received signals. DTE doesn't communicate information but ...
Read MoreWhat is the Point-to-Point Tunneling Protocol(PPTP)?
The Point-to-Point Tunnelling Protocol (PPTP) is a collection of communication protocols that control the safe implementation of virtual private networks (VPN), which enable businesses to extend their own private networks across the public Internet via "tunnels."A big corporation with offices worldwide can use PPTP to construct a large local area network (LAN) – basically a VPN - by using the architecture of a Wide Area Network (WAN), such as the network of a public Internet Service Provider (ISP) or telco. This is less expensive than setting out network infrastructure across such long distances.Through the construction of a VPN across TCP/IP-based ...

Advanced Peer-to-Peer Networking (APPN) associates in the nursing element of an IBM Systems spec (SNA). It involves protocols within which a group of computers don't seem to be dominated by a central server or the other piece of hardware rather these protocols enable computers to speak among themselves.Advanced Peer-to-Peer Networking (APPN) is the moment generation of Systems spec (SNA). It had been created by IBM to satisfy these prerequisites −To supply a compelling directional convention to allow SNA activity to stream natively and at the same time with different protocols.To permit sessions to be designed up between the conclusions purchasers ...
