If you are reading this article, you are most likely connected to the internet and viewing it at the Scaler Topics. Likely, you are currently utilizing Network Address Translation (NAT). More people now use the internet than ever anticipated, leading to the situation where the number of unique IP addresses provided by the IPv4, i.e.i.e.,232232 or 4,294,967,2964,294,967,296, is not enough. Network ...
When the IP system was first introduced, finding a network and sending data to it was easier because the number of users on the internet was limited. As the number of users on the internet is increasing, sending a data packet to the computer you want in a network is becoming quite difficult these days. When a ...
In the OSI model, the application layer is the layer closest to the end-user, implying that the application layer and the end-user can interact directly with the software application. The application layer isn’t an application. Instead, it’s a component within an application that manages how data is sent to and received from other devices. It’s an abstraction ...
Voice over Internet Protocol(VoIP) is a way of transmitting voice and multimedia over a network. VoIP enables users to place voice calls via their computer, smartphone, other mobile devices, dedicated VoIP phones, and WebRTC-capable browsers. VoIP is a technology that benefits consumers and businesses because it typically includes features not available on traditional phone services. ...
Transmission mode, also known as a communication mode, is the transfer of data between two devices via a communication channel that includes an optical fiber, wireless channels, copper wires, and other storage media . Data is transmitted between two devices in the form of electromagnetic waves. There are numerous data transmission methods in which the message is delivered in the form ...
Network devices are physical devices that enable communication and interaction between hardware on a computer network. Each networking device operates in a distinct computer network segment and performs distinct functions. A network may require hundreds or thousands of different network devices to maintain and build out various LAN and WAN. Network devices like the hub, bridge, repeater, modem, router, gateway, etc., are the basic building blocks of an extensive network. What ...
Similar to how a phone’s contacts list matches names to numbers, the domain name system is a naming database that locates and translates internet domain names to their unique IP addresses. DNS is used in various internet activities to swiftly discover an IP address to connect to and access content. DNS is important because, for humans, it’s ...
WiFi or wireless fidelity is a wireless networking technology that connects computers (laptops and desktops), mobile devices (smartphones and wearables), and other equipment (printers and video cameras) to the Internet. It enables these devices, as well as many others, to communicate with one another, forming a network. In today’s world, WiFi is one of the most important means ...
TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols that makes data exchange between two devices possible. TCP/IP specifies how data should be packetized, addressed, transmitted, routed, and received on a network by providing end-to-end communication. As compared to the OSI model, which is a theoretical model, TCP/IP is an application and practical ...
MQTT stands for Message Queuing Telemetry Transport and is a lightweight publish/subscribe messaging protocol for Machine to Machine(M2M) telemetry in low bandwidth environments. It was developed in 1999 by Arlen Nipper and Andy Stanford-Clark of IBM to link Oil Pipeline telemetry systems through satellite. It was once a proprietary protocol, but in 2010 MQTT was made available royalty-free, and in 2014 MQTT was made an OASIS standard. MQTT ...
