Introduction The “traceroute” command is a network diagnostic tool that allows users to track the route that a packet takes from the source computer to the destination. This tool is widely used by network administrators and engineers to troubleshoot network issues such as high latency, packet loss, and connectivity problems. Traceroute works by sending packets with gradually increasing Time-To-Live (TTL) values to the destination. As each packet reaches a router, the router decrements the TTL value by 1 and discards the packet if the TTL value becomes zero. The traceroute command listens for error messages sent back by the routers ... Read More
Python is a widely used high-level programming language. To write and execute code in python, we first need to install Python on our system.Installing Python on Windows takes a series of few easy steps.Step 1 − Select Version of Python to InstallPython has various versions available with differences between the syntax and working of different versions of the language.

If your website does not appear on the search engine results page after applying all SEO techniques, it could mean your website's contents are not canon. "non canon" means your website contents are not specific. It happens when your website content does not have master content, creating duplicate content. To fix this issue, you have to use a canonical tag. What are Canonical Tags? Canonical tags are HTML links designed to inform search engines that have a master copy. In this process, you use one specific URL representing the master copy of the duplicate pages. Simply put, it tells ... Read More
A Certified Ethical Hacker (CEH), commonly called a "White Hat Hacker, " is a trained expert who identifies and repairs computer and network security flaws by employing the same techniques and tools used by hostile hackers. From the beginning of the internet, hackers have utilized their sophisticated tools to take advantage of whatever weak spot they might uncover in a system's defenses. On the other hand, security experts following the ethical hacking roadmap are the good guys trying to patch up IT systems before exploiting them. The Certified Ethical Hacker (CEH) credential from the EC Council is highly regarded and ... Read More
Introduction The quadratic equation is a one-variable polynomial equation with degree two. The highest power of the unknown variable in a quadratic equation is two. The general form of a quadratic equation f(x) with variable x is f(x)=ax2+bx+c=0, in which a≠0 and a, b, c ϵ R. Every quadratic equation has two roots which can be real or imaginary. The discriminant of a quadratic equation determines the nature of the roots. The roots can be calculated using the quadratic formula. Quadratic Equations A Quadratic equation is a polynomial equation of one variable with a degree of two. The general ... Read More
Introduction Polynomials are mathematical expressions containing variables and coefficients. James Waddell Alexander II invented the concept of the polynomial. There are various terms associated with the polynomial. In this tutorial, we will discuss the meaning of polynomial, various correlations between the zeroes and the coefficients of polynomial equations with solved examples. Polynomials Polynomials are defined as the algebraic expressions containing one or more variable terms multiplied by constant terms. There are two terms associated with a polynomial, such as coefficients (i.e., constants) and variables. For example, $\mathrm{\mathit{f}(p)=p^2+2p+5}$ is an example of a polynomial. The given polynomial is denoted by f(p). ... Read More
Introduction In our daily life, we come across various geometrical objects whose dimensions need to be measured for convenience. In this direction, there are various measuring instruments invented and used. In addition, the measured amount is expressed by various units. In this tutorial, we will discuss the units of measurement of length, metric system, feet system, various units, and their mutual conversion with solved examples. Units of Measurement of Length The measurement of length means to measure the distance between two end-points of the specific object. It is a skill that helps us measure the length of various objects. ... Read More
Introduction In daily life, we come across various geometrical objects, which are bounded by straight line segments. These are known as polygons. The polygons are categorized into various types based on their number of sides and angles. The rectangle is one type of polygon extensively used in Euclidean geometry. Various objects such as black boards, carrom boards, books, doors, smartphones, beds, etc. These are real-life examples of the rectangle. In this tutorial, we will discuss the meaning, properties, types, and basic formulae related to the rectangle with solved examples. Rectangle A rectangle is a two-dimensional polygon embedded in four ... Read More
