Session Hijacking involves an attacker stealing a user's session token and using it to impersonate the user. This attack allows unauthorized access to sensitive data.

The WHERE clause in SQL is used to filter results based on a specified condition. It allows you to specify conditions that the data must meet to be included in the result set.

In Cassandra, the placement of data on nodes is determined by the Partition Key. It is crucial for distributing data across the cluster efficiently.

The time complexity of accessing an element in an array is O(1) or constant time. This is because arrays provide direct access to any element using its index, and the access time remains constant regardless of the array size.

The main difference between Docker and Kubernetes lies in their functionalities. Docker is primarily a containerization platform, used to package and run applications in isolated environments called containers. On the other hand, Kubernetes is a container orchestration platform that automates the deployment, scaling, and management of containerized applications. While Docker manages individual containers, Kubernetes manages clusters of containers, offering features like load balancing, auto-scaling, and self-healing.

The command "git pull" is equivalent to "git fetch" followed by git merge. This combination fetches changes from the remote repository and merges them into the current branch. It helps in keeping your local branch up-to-date with the remote branch.

TDD encourages developers to write Integration tests to cover different aspects of the software. Integration tests ensure that different components or modules work together as expected when integrated into a complete system.

The CAP theorem in NoSQL databases stands for Consistency, Availability, and Partition Tolerance. It implies that in the presence of a network partition, a distributed system must choose between consistency and availability.

In Docker, a Dockerfile defines the environment in which a container runs. It specifies the base image, dependencies, and commands needed to create the container.

To center align an element horizontally in CSS, you can use margin: auto;. This property automatically distributes the remaining space on both sides of the element, centering it within its container.

The Factory Method design pattern is useful when you want to decouple the client code from the concrete classes it uses, allowing flexibility in object creation without changing the client code.

RESTful APIs follow the principle of Convention over Configuration (CoC). This means that developers only need to specify unconventional aspects of the application. Conventions are predefined rules that simplify development and promote consistency.
