Right Answer: I have hands-on experience with DaVinci Developer for creating and managing AUTOSAR software components, using DaVinci Configurator for configuring and generating AUTOSAR XML files, and working with EB tresos for system configuration and integration of AUTOSAR modules.
Right Answer: Sender-receiver communication is a one-to-one communication model where a sender transmits messages directly to a receiver, typically used for periodic data exchange. Client-server communication, on the other hand, involves a client requesting services or data from a server, which processes the request and sends back a response, often used for more complex interactions and service-oriented architectures.
Right Answer: Common types of linking errors include:
1. **Undefined References**: Occurs when a function or variable is declared but not defined. Resolve by ensuring all referenced functions/variables are defined and linked correctly.
2. **Multiple Definitions**: Happens when the same function or variable is defined in multiple files. Resolve by using `extern` for declarations in header files and ensuring only one definition exists.
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
Right Answer: Flexbox, or the Flexible Box Layout, is a CSS layout model that allows items in a container to be arranged and aligned efficiently. It works by defining a container as a flex container using `display: flex;`, which enables its direct children (flex items) to be laid out along a main axis (horizontal or vertical). You can control the alignment, direction, spacing, and size of these items using properties like `flex-direction`, `justify-content`, `align-items`, and `flex-wrap`. This makes it easier to create responsive layouts without using floats or positioning.
Right Answer: The DOM (Document Object Model) is a programming interface for web documents that represents the structure of a webpage as a tree of objects. You can manipulate the DOM using JavaScript by selecting elements (e.g., using `document.getElementById`, `document.querySelector`), modifying their properties (e.g., `element.innerHTML`, `element.style`), adding or removing elements (e.g., `element.appendChild`, `element.remove`), and responding to events (e.g., `element.addEventListener`).
Right Answer: `var` is function-scoped or globally-scoped and can be re-declared and updated. `let` is block-scoped, can be updated but not re-declared in the same scope. `const` is also block-scoped, cannot be updated or re-declared, and must be initialized at the time of declaration.
Right Answer: Promises in JavaScript are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value. They allow you to handle asynchronous code more easily by providing methods like `.then()` for success and `.catch()` for errors.
`async` and `await` are syntactic sugar built on top of promises. An `async` function always returns a promise, and within an `async` function, you can use `await` to pause execution until a promise is resolved, making the code easier to read and write as if it were synchronous.
Right Answer: A web server handles an HTTP request by following these steps:
1. **Receive Request**: The server listens for incoming HTTP requests on a specific port (usually port 80 for HTTP or port 443 for HTTPS).
2. **Parse Request**: It parses the request to extract the method (GET, POST, etc.), URL, headers, and body.
3. **Process Request**: The server determines how to respond based on the request. This may involve retrieving files, querying a database, or executing server-side scripts.
4. **Generate Response**: It creates an HTTP response, which includes a status code (like 200 for success), headers, and the requested content (like HTML, JSON, etc.).
5. **Send Response**: The server sends the response back to the client (usually a web browser) over the network.
6. **Log Request**: Optionally, the server logs the request details for monitoring and analysis.
