A computer or any other networking device such as a router, needs a modem in order to connect to the Internet. The term "modem" is an acronym for "modulator-demodulator, " and it refers to the hardware device.In the realm of computer networking, the word "gateway" can refer to a number of different things depending on the circumstances. A gateway is a type of networking equipment that, in general, serves to connect two or more distinct networks together. Its primary function is to act as a link between networks that make use of distinct architectural styles, protocols, or platform types.Read through ... Read More

The primary distinction between a widget and an app is that the former refers to a piece of software that is straightforward and simple to operate, and it can be integrated into a variety of software platforms, whereas the latter refers to a self-contained, feature-rich software application that has been developed exclusively for use on mobile devices.Widgets are programmes that are pre-installed and run in the background continuously. In order to give the home screen a more aesthetically pleasing appearance, certain applications use widgets rather than icons. In addition, widgets can link to various programmes.On the other hand, an application ... Read More

Refrigerator and Air Conditioner (AC) are both electrical appliances that are used to reduce the temperature of a closed space by transferring the heat of the closed space to another place. Both AC and refrigerator work on the principle of heat-sinks, i.e., these devices transfer the heat from a source (or closed space) to another place called sink.Read through this article to find out how Air Conditioners are different from Refrigerators.What is an Air Conditioner?An Air Conditioner is an electrically operated cooling device which is generally used to cool a large closed space such as a room or a hall. ...

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

Let us understand the concepts of Internet of Things (IOT) and Industrial Internet of Things (IIOT) before learning the differences between them.Internet of Things (IOT)It is described as the physical devices like mobiles, Pc’s, home appliances and many more electronic devices that are embedded with sensors, software’s and other technologies to transmit the data and to communicate among the devices through the Internet.For example: air conditioners, sensors, smart watches, mobile phones etc.Industrial Internet of Things (IIOT)It is described as using the internet of things in industrial applications and sectors.The IIOT refers to inter-connected sensors and other networked devices together with ...

IoT communication protocols are modes of communication which ensure the security of the data that is being exchanged between IoT connected devices.IoT devices can be connected through an IP network or a non-IP network. Even though there is a difference in their memory, range, and power use.But connections via IP networks are complex and also take high memory and power from the IoT devices even though the range is not a problem. Non-IP networks like Bluetooth which require less memory and power but have a range limitation.Communication ProtocolsThe most common use communication protocols of IoT are as follows −BluetoothWi-FiZigbeeMQTTOPC- UACellularZ-waveLoRaWANBenefitsThe ...

Internet of Things (IoT) is a system of interrelated, internet-connected objects which are able to collect and transfer data over a wireless network without human intervention.For example, smart fitness bands or watches, driverless cars or drones, smart homes that can be unlocked through smartphones and smart cars, etc.Architecture of IoTThere are different phases in the architecture of IoT but they can vary according to the situations but generally, there are these four phases in the architecture of IoT −Networked DevicesThese are the physical devices which include sensors, actuators, and transducers. These are the actual devices that collect and send the ... Read More

IoT is a system of interrelated, internet-connected objects which are able to collect and transfer data over a wireless network without human intervention. The examples of IoT are driverless cars or drones.RequirementsThe requirement that an IoT operating system (OS) should satisfy are given below −The Operating System specifically for IOT Purpose should be portable that means it can be easily ported to different hardware platforms.It should support connectivity with different protocols like Ethernets, Wi-Fi and BLE.Operating systems should have low memory, power should be minimal consumed and overhead due to the OS should be low.OS scalability should be there so ...

Campus Area Network (CAN) is also called a corporate area network and it helps to like LAN with small geographical space. The main objective is offering the best accessibility of campus residential regions like schools, colleges, university, small institutes (Campus), and corporate area (building). It is larger than LAN but small than WAN and MAN networksIt can cover many buildings in an area. Here all computers are connected together and have some relationship to each other.For example − Different buildings in a campus are connected using Campus Area Network (CAN) they help to interconnect departments, library and computer laboratories.Given below ...
