Network devices or networking hardware are the physical devices that are used for establishing connections and facilating interaction between different devices in a computer network. Hub Hubs work in the physical layer of the OSI model. A hub is a device for connecting multiple Ethernet devices and making them act as a single network segment. It has multiple inputs and output ports in which a signal introduced at the input of any port appears at the output of every port except the original incoming port. A hub can be used with both digital and analog data. Hubs do not perform ... Read More
We can resolve the exception – ElementNotInteractableException with Selenium webdriver. This exception is thrown if a webelement exists in DOM but cannot be accessed. The below image shows an example of such an exception.If a specific webelement is overspread by another webelement we normally get this exception. To fix this, we can either apply explicit wait so that the webdriver waits for the expected condition - invisibilityOfElementLocated of the overlaying webelement.Or, we can apply the expected condition - elementToBeClickable on the webelement that we want to interact with. To resolve a permanent overlay, we have to use the JavaScript Executor ... Read More
Octal number is one of the number systems which has value of base is 8, that means there only 8 symbols − 0, 1, 2, 3, 4, 5, 6, and 7. Whereas Binary number is most familiar number system to the digital systems, networking, and computer professionals. It is base 2 which has only 2 symbols − 0 and 1, these digits can be represented by off and on respectively.Conversion from Octal to Binary number systemThere are various direct or indirect methods to convert a octal number into binary number. In an indirect method, you need to convert an octal ... Read More
Introduction Grep is a powerful command line utility on Linux that allows users to search for patterns in text files. It is widely used for tasks such as searching log files for specific strings or patterns, searching for specific lines in a configuration file, or extracting information from a large dataset. One of the useful features of grep is the ability to exclude multiple patterns from the search. This can be useful when you want to filter out irrelevant or unwanted results from your search. In this article, we will discuss how to exclude multiple patterns with grep on Linux. ... Read More
To concatenate a string to an int value, use the concatenation operator.Here is our int.int val = 3;Now, to concatenate a string, you need to declare a string and use the + operator.String str = "Demo" + val;Let us now see another example.Example Live Demoimport java.util.Random; public class Demo { public static void main( String args[] ) { int val = 3; String str = "" + val; System.out.println(str + " = Rank "); } }Output3 = Rank

Tkinter Label widget can be aligned using the anchor attributes. In order to calculate the accommodate spacing and alignment of the widget, anchor would help in a better way. Anchor provides several options such as N, W, S, E, NW, NE. SW, SE which can be defined in the pack manager itself.ExampleIn the following example, we will align the Label text of an application to the left by adding the anchor attribute towards “w” direction.#Import the required library from tkinter import* #Create an instance of tkinter frame win= Tk() #Set the geometry win.geometry("750x250") #Create a Label Widget Label(win, text= "New ...

Whether it is possible to traverse a graph from one vertex to another is determined by how a graph is connected. Connectivity is a basic concept in Graph Theory. Connectivity defines whether a graph is connected or disconnected.ConnectivityA graph is said to be connected if there is a path between every pair of vertex. From every vertex to any other vertex, there should be some path to traverse. That is called the connectivity of a graph. A graph with multiple disconnected vertices and edges is said to be disconnected.Cut VertexLet 'G' be a connected graph. A vertex V ∈ G ... Read More
Distributed Operating System is a type of model where applications are running on multiple computers linked by communications. It is an extension of the network operating system which supports higher levels of communication and integration of the machines on the network. Distributed OS runs on multiple CPUs but for an end-user, it is just an ordinary centralized operating system. It can share all resources like CPU, disk, network interface, nodes, computers, etc. from one site to another site, and it increases the data available on the entire ... Read More
