SQL databases are relational and have a fixed schema, meaning data is organised into structured tables with predefined relationships. They use the structured query language (SQL) for querying. 

On the other hand, NoSQL databases use various data models (e.g., document-based, key-value, column-family) and have flexible or schema-less designs. They often prioritise horizontal scalability and can handle unstructured or rapidly changing data. SQL databases prioritise strong consistency and ACID transactions, while NoSQL databases may offer various levels of consistency and prioritise performance and scalability. 

• What divides the Agile and Waterfall methods?

Agile software program development is a technique that enables cooperation, and Waterfall software program development places better precedence on planning and documentation.

• How do SVN and Git differ from one another?

Git is a worldwide version control gadget that enables builders to work on the same file simultaneously. SVN is a controlled model device that forces developers to work on specified tasks.

• What distinguishes a simple internet site from a dynamic one?

A simple internet site gives the same records to each consumer. However, a dynamic internet site allows you to convert content depending on the consumer's choices.

• What distinguishes GET searches from POST requests?

A GET request obtains statistics from a server, while a POST request supplies data to a server.

• What makes a stack different from a queue?

A stack primarily operates on the Last-In-First-Out (LIFO) principle, while on the other hand, a queue typically follows the First-In-First-Out (FIFO) principle, highlighting a significant difference between these two.

• What makes a binary seek tree distinct from a hash table?

Compared to a hash table, which applies a hash function to map keys to values, a binary seek tree uses a binary tree to keep objects in a distinct order.

• Distinguish a processor from an interpreter.

A processor transforms source code into gadget code while an interpreter executes supply code simultaneously.
