In this tutorial, we will learn about Max parallel HTTP connections in a browser. To know more about this topic, we will first understand what parallel connections are, the reasons behind blocking and how to solve it, and the browser limitations. Parallel Connections By entirely requesting the original HTML page, the first embedded item, the second embedded object, etc., a browser may naively process each embedded object in sequence. But it moves too slowly! HTTP enables clients to establish connections and parallelly carry out numerous HTTP transactions. Parallel Connections Could Speed Up Page Loading. If composite pages with embedded objects ... Read More

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:http://tutorialspoint.com. The browser will deny my request and prevent me from accessing resources from ... Read More

One of the most common problems with internet systems is that they are too complex for an average person to comprehend. Even a simple home-based system is complicated. The complexity of larger firms and agencies dealing with hundreds or even thousands of computers on the network increases dramatically.A tool called Nmap can be used to find out which ports are open and what the regulations are. This application scans the network to which a computer is connected and displays a list of ports, device names, operating systems, and other identifiers to assist the user in understanding the intricacies of their ...

Ensure that none of the devices on your network are affected. Once you've established that your network is clean and that no illegal traffic is being sent out, find out where your IP address was blacklisted or blocked, then contact them to have it removed.There will be multiple procedures to request an IP removal from each blacklist or blocklist. And just because you've asked for removal doesn't mean they'll follow through.Challenges with IP BlacklistingEven while blacklisting is an excellent approach to prohibit particular IP addresses from accessing your network, it isn't always successful. The reason for this is that attackers ... Read More

Let us understand the concepts of Wifi extender and Wifi booster before learning the differences between them.Wi-Fi ExtenderA Wi-Fi repeater, extender, or booster all are devices which are used to forward wireless signals from the router that covers a larger area like multiple floors of a house. A Wi-Fi extender, also called a wireless network extender or wired-wireless network extender, varies with a small difference.The Wi-Fi device uses both wired and wireless technologies to bring a wireless signal to an area of the home where network coverage has been weak. It enables all wireless devices within the expanded coverage area ... Read More

Port is a logical address of any protocol or we can call it a dedicated door for each protocol in which all the packets fall in that box. We can also say that the mailbox for each protocol is a box in which each protocol packet is dropped.Later on the receiver will open that packet and read the content which the sender has sent. Port is a dedicated separate line for packet transmission for each protocol.TCP is called as Transmission control protocol which provides a communication service between an application program and the Internet protocol (IP)A port is a number ...

A replay attack is the type of malicious attack which is initiated by the hacker on a secure network to intercept a communication. Once the interception takes place, the messages are sent to the wrong node so that the conversation can be moulded as per hackers’ needs.These kinds of attacks are carried out by the attacker who is intercepting the data and re-transmitting them at their own time and use. This is kind of a low level for the Man-in-the-middle attack where the attacker uses the security protocols which uses the replay of the messages and fools the participants thereby ... Read More

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 ...
