A graph is a data structure used to represent a collection of interconnected entities, called vertices, which are linked by edges. Graphs can be directed or undirected, depending on whether the connections have a specific direction, and they can also be weighted, where edges carry values representing the cost or distance between vertices. Graphs are widely used in various applications such as social networks, transportation systems, and web page linking, allowing for the representation of complex relationships and enabling algorithms for searching, pathfinding, and network analysis.

A table is a structured data format that organizes information into rows and columns, resembling a spreadsheet. Each row typically represents a unique record, while each column corresponds to a specific attribute or field of that record. Tables are a fundamental component of relational databases, allowing for efficient storage, retrieval, and manipulation of data. They facilitate operations such as querying, updating, and joining different datasets, making them essential for applications that require organization and quick access to large volumes of information.
