ABAP

Ques:- What are user exits, customer exits, and enhancements in ABAP

Asked In :- Vinove Software & Services Pvt Ltd, Solitaire Infosys, Principal Global Services, COEPD, Deligence Technologies, Manipal Technologies, Codelogicx Technologies, OPENSPACE SERVICES, First Zen, Xobin,

Right Answer:
User exits, customer exits, and enhancements in ABAP are ways to extend the functionality of SAP applications without modifying the original code.

- **User Exits**: Predefined points in the SAP code where you can add custom code. They are typically found in function modules and allow for modifications in standard SAP processes.

- **Customer Exits**: Similar to user exits, but they are specifically designed for customer-specific enhancements. They are implemented using function modules and include additional parameters for custom logic.

- **Enhancements**: A broader term that includes user exits and customer exits, as well as other methods like BAdIs (Business Add-Ins) and enhancement spots. They provide a structured way to add custom functionality to SAP applications while maintaining upgrade compatibility.

3. **Library Not Found**: Occurs when the linker cannot find a specified library. Resolve by checking the library path and ensuring the library is correctly installed and linked.

4. **Incompatible Object Files**: Happens when object files are compiled with different settings or incompatible versions. Resolve by recompiling all object files with consistent settings.

5. **Symbol Conflicts**: Occurs when two or more symbols have the same name. Resolve by renaming conflicting symbols or using namespaces.

6. **Incorrect Link Order**: Happens when libraries are linked in the wrong order, causing dependencies to be unresolved

Web Development

Ques:- What is the difference between inline inline block and block elements

Asked In :- Vinove Software & Services Pvt Ltd, Queppelin Technology Solutions, Walkover Web Solutions, CakeSoft Technologies, Recodem, Energytech Global, Incise Infotech, First Zen, Angular Minds, CIGNEX Datamatics Technologies,

Right Answer:
Block elements take up the full width available and start on a new line (e.g., `<div>`, `<h1>`). Inline elements only take up as much width as necessary and do not start on a new line (e.g., `<span>`, `<a>`). Inline-block elements are similar to inline elements but can have width and height set, and they respect margins and padding (e.g., `<img>`, `<button>`).

Web Development

Ques:- What are cookies sessions and local storage in web development

Asked In :- Unyscape Infocom Pvt. Ltd., Vinove Software & Services Pvt Ltd, DREAMORBIT SOFTECH PVT, Object Frontier Software, Medvarsity Online, Itobuz Technologies, Addweb solutions, Fortunesoft IT Innovations, Born Commerce, Priya Softweb Solutions,

Right Answer:
Cookies are small pieces of data stored on the user's computer by the web browser while browsing a website, used for tracking and remembering information about the user. Sessions are temporary storage on the server that keeps track of user data across multiple requests during a single visit, typically expiring when the user closes the browser. Local storage is a web storage feature that allows websites to store data in the user's browser persistently, even after the browser is closed, with no expiration time.

Ques:- What is the difference between HTML and HTML5

Asked In :- Vinove Software & Services Pvt Ltd, Hummingbird Web Solutions, Aakit Technologies, Namecheap Web Services, TNQ Technologies, Adnate IT Solutions, Spark Infosys, Keyideas Infotech, SysTrack Solution, CodeClouds IT Solutions,

Right Answer:
HTML5 is the latest version of HTML, which includes new features such as native support for audio and video, new semantic elements (like `<article>`, `<section>`, and `<header>`), improved parsing rules, and better support for web applications with APIs like local storage and canvas. HTML, on the other hand, refers to earlier versions that lack these enhancements.

Web Development

Ques:- What are JavaScript closures and how do they work

Asked In :- Vinove Software & Services Pvt Ltd, Trigent Software, Codiant Software Technologies, Born Commerce, Oodles Technologies, Radicle Software, SPARX IT SOLUTIONS, Energytech Global, Adnate IT Solutions, Muvi Entertainment,

Right Answer:
JavaScript closures are functions that remember their outer scope even when the function is executed outside that scope. They work by capturing the variables from their surrounding environment, allowing access to those variables even after the outer function has finished executing. This is useful for data encapsulation and maintaining state in asynchronous programming.

Right Answer:
To test mobile applications on different devices, you can use the following methods:

1. **Real Device Testing**: Use physical devices to test the app on various screen sizes, operating systems, and hardware configurations.
2. **Emulators and Simulators**: Utilize emulators (for Android) and simulators (for iOS) to mimic different devices and test the app's functionality.
3. **Cloud Testing Services**: Leverage cloud-based testing platforms like BrowserStack or Sauce Labs that provide access to a wide range of devices and configurations.
4. **Automated Testing Tools**: Implement automated testing frameworks like Appium or Espresso to run tests across multiple devices efficiently.
5. **Manual Testing**: Conduct manual testing on key devices to ensure user experience and functionality are consistent.

By combining these methods, you can effectively test mobile applications across different devices.
