Non-Relational Databases
Non-Relational Databases Non-relational databases, often called NoSQL databases, are designed to store data in a more flexible format compared to relational databases. They can handle structured, semi-structured, and unstructured data, making them ideal for modern applications that deal with diverse data types. Instead of tables with fixed rows and columns, non-relational databases use user-defined models…

Stack‑based Buffer Overflow
Stack‑based Buffer Overflow A stack‑based buffer overflow happens when a program writes more data into a stack‑allocated buffer than it was designed to hold. Because the stack stores important control data (like return addresses), overflowing a buffer can overwrite that data and change how the program executes. The following code contains a function named hidden…
