Unions inside structures allow multiple variables to share the same memory location. They are used when only one variable needs to be active at a time.

• Unions are used when you want to save memory by sharing the same memory location for different variables in a structure.

• Only one variable inside the union can be active at a time, as they all share the same memory space.

• Unions are useful when you have a structure with multiple variables, but only one variable needs to be active...read more

CAN (Controller Area Network) has multiple layers including physical, data link, network, transport, and application layers. Each layer has specific functionality.

• Physical layer: Handles the transmission of bits over the physical medium.

• Data link layer: Manages the transmission of data frames between nodes.

• Network layer: Controls the flow of data between nodes on the network.

• Transport layer: Ensures reliable data transfer between nodes.

• Application layer: Provides interfaces f...read more

Jenkins has a wide range of plugins for various functionalities.

• Pipeline plugins (e.g. Pipeline, Multibranch Pipeline)

• SCM plugins (e.g. Git, SVN)

• Build and test plugins (e.g. Maven, JUnit)

• Notification plugins (e.g. Email, Slack)

• Monitoring plugins (e.g. Prometheus, Grafana)

Integrating other tools to Jenkins involves using plugins and configuring build pipelines.

• Install the necessary plugins for the tools you want to integrate with Jenkins

• Configure the tools in Jenkins global configuration settings

• Create build pipelines that include steps for interacting with the integrated tools

• Use Jenkins API to automate interactions with external tools

Nodes can be named based on their functionality, purpose, or position in a hierarchy.

• Name based on functionality (e.g. loginNode, paymentNode)

• Name based on purpose (e.g. validationNode, processingNode)

• Name based on position in hierarchy (e.g. parentNode, childNode)

HTTPS is a secure communication protocol used for secure communication over the internet. SSH cloning is a method of cloning a repository using the SSH protocol.

• HTTPS stands for Hypertext Transfer Protocol Secure and is used to secure communication over the internet.

• It encrypts the data being transmitted between the client and the server, providing a secure connection.

• SSH cloning is a method of cloning a Git repository using the SSH protocol instead of HTTPS.

• It allows for sec...read more

Jenkins node is a machine that executes tasks as part of a Jenkins build process.

• Jenkins nodes can be physical machines or virtual machines.

• Nodes can be configured to run specific types of jobs or tasks.

• Nodes help distribute workload and improve efficiency in Jenkins pipelines.

The question is asking for the names of Com APIs in each BSW layer.

• BSW layer refers to the Basic Software layer in an embedded system.

• Com APIs are communication application programming interfaces.

• Provide the names of Com APIs used in each BSW layer.

• Example: BSW Layer 1 - CanIf, BSW Layer 2 - CanTp, BSW Layer 3 - ComM

Docker is a containerization platform for running applications in isolated environments, while Docker Swarm is a tool for orchestrating multiple Docker containers across multiple hosts.

• Docker is used for creating and managing containers, while Docker Swarm is used for managing multiple containers across multiple hosts.

Jenkins library is a collection of reusable code that can be shared across multiple Jenkins pipelines.

• Jenkins library allows for code reuse and sharing across pipelines

• It helps in maintaining consistency and reducing duplication of code

• Libraries can be stored in version control systems like Git and referenced in Jenkins pipelines

K8s is a container orchestration tool while Docker Swarm is a clustering and scheduling tool for Docker containers.

• K8s is more widely used and has a larger community support compared to Docker Swarm.

• K8s supports more advanced features like auto-scaling, self-healing, and rolling updates.

• Docker Swarm is easier to set up and manage for smaller scale deployments.

• K8s uses declarative configuration while Docker Swarm uses imperative configuration.

• K8s has a more complex architectur...read more

Expected value is the average outcome of a random variable over a large number of trials.

• Expected value is calculated by multiplying each possible outcome by its probability and summing them up.

• It represents the long-term average of a random variable.

• For example, the expected value of rolling a fair six-sided die is (1+2+3+4+5+6)/6 = 3.5.

Git hooks are scripts that run automatically before or after certain Git commands are executed.

• Git hooks are customizable scripts that can be triggered by specific Git events.

• They can be used to enforce coding standards, run tests, or automate deployment processes.

• Examples of Git hooks include pre-commit, post-commit, pre-push, and post-merge hooks.

C programming is a high-level programming language used for system programming, embedded systems, and creating applications.

• C programming is a procedural language with a rich set of built-in functions.

• It is widely used for developing operating systems, compilers, and other system software.

• C programs are efficient and fast due to direct access to system hardware.

• Example: Writing a simple 'Hello World' program in C.

A make file is a script that automates the compilation and building process of software projects.

• Make files are commonly used in Unix-like operating systems.

• They specify the dependencies between source files and the commands to compile and link them.

• Make files can be written using the makefile syntax or other scripting languages like Bash.
