Async Await is a feature in JavaScript that allows asynchronous code to be written in a synchronous style.

• Async Await is used to simplify the syntax of writing asynchronous code.

• It allows the use of the 'await' keyword to pause the execution of a function until a promise is resolved.

• It is commonly used with promises to handle asynchronous operations.

• Async functions always return a promise.

• Example: async function getData() { const response = await fetch('https://example.com/da...read more

Promise is an object representing the eventual completion or failure of an asynchronous operation.

• Promises are used to handle asynchronous operations in JavaScript

• They are a cleaner alternative to callbacks

• Promises have three states: pending, fulfilled, or rejected

• They can be chained using .then() and .catch() methods

• Example: new Promise((resolve, reject) => {...})

The formula for end deflection of a cantilever beam with end load is (5 * load * length^4) / (384 * E * I)

• The formula takes into account the load applied at the end of the cantilever beam, the length of the beam, the modulus of elasticity (E), and the moment of inertia (I) of the beam.

• The deflection is directly proportional to the load and the length of the beam, and inversely proportional to the modulus of elasticity and the moment of inertia.

• The formula assumes that the bea...read more

The end deflection of a cantilever with a mid-point load depends on the length and stiffness of the cantilever.

• The end deflection can be calculated using the formula: δ = (P * L^3) / (48 * E * I)

• Where δ is the end deflection, P is the load applied at the mid-point, L is the length of the cantilever, E is the modulus of elasticity, and I is the moment of inertia.

• The end deflection increases with increasing load and length, and decreases with increasing stiffness.

• For example, a...read more

Needle roller bearings and CRB (Cylindrical Roller Bearings) are both types of roller bearings used in different applications.

• Needle roller bearings have a smaller diameter and higher length-to-diameter ratio compared to CRB.

• Needle roller bearings are suitable for applications with limited radial space, such as in automotive transmissions.

• CRB bearings have a larger diameter and lower length-to-diameter ratio, providing higher load-carrying capacity.

• CRB bearings are commonly u...read more

To catch up with the latest security trends, one can attend conferences, read industry publications, participate in online forums, and engage in hands-on training.

• Attend security conferences such as Black Hat or DEF CON

• Read industry publications like SecurityWeek or Dark Reading

• Participate in online forums and communities like Reddit's netsec or Stack Exchange's Information Security

• Engage in hands-on training through platforms like Hack The Box or TryHackMe

Risk assessment is performed by identifying potential risks, analyzing their likelihood and impact, and developing mitigation strategies.

• Identify potential risks by analyzing project requirements, stakeholder expectations, and external factors.

• Analyze the likelihood and impact of each identified risk using qualitative or quantitative methods.

• Develop mitigation strategies to address high-risk areas and minimize their impact on project delivery.

• Regularly review and update the r...read more

There are several types of bearings used in various applications, including ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings are the most common type and consist of balls between two rings.

• Roller bearings use cylindrical rollers instead of balls for higher load capacity.

• Plain bearings have a sliding surface and are used in applications with low speed and heavy loads.

• Fluid bearings use a thin layer of fluid to support the load and reduce frictio...read more

Business analysis involves identifying business needs and finding solutions to business problems.

• Business analysis involves identifying business needs and determining solutions to business problems.

• It includes analyzing processes, systems, data, and organizational structures.

• Business analysts use various techniques such as SWOT analysis, stakeholder analysis, and requirements gathering.

• The goal of business analysis is to improve efficiency, productivity, and profitability of ...read more

Integrating Kubernetes with Azure requires setting up an AKS cluster and configuring authentication and networking.

• Create an AKS cluster in Azure

• Configure authentication using Azure Active Directory or Kubernetes RBAC

• Configure networking using Azure Virtual Network and Kubernetes Service CIDR

• Deploy and manage applications using kubectl or Azure DevOps

• Use Azure Monitor for monitoring and logging

• Use Azure Container Registry for storing container images

MVC in .NET stands for Model-View-Controller, a software architectural pattern for developing web applications.

• Model represents the data and business logic of the application

• View is responsible for the presentation layer and user interface

• Controller handles user input, processes requests, and interacts with the model and view

• Promotes separation of concerns and modularity in application development

• Example: ASP.NET MVC framework implements the MVC pattern in .NET

Testing techniques include black box testing, white box testing, unit testing, integration testing, system testing, regression testing, and acceptance testing.

• Black box testing focuses on the functionality of the software without looking at its internal code.

• White box testing involves testing the internal code structure, paths, and branches.

• Unit testing tests individual units or components of the software.

• Integration testing tests the integration of different components or mo...read more
