10+ HDB Financial Services Interview Questions and Answers

The GC full name refers to the Garbage Collector, a component of a programming language that automatically manages memory allocation and deallocation.

• GC stands for Garbage Collector.

• The GC is responsible for automatically reclaiming memory that is no longer in use by a program.

• Different programming languages have their own implementations of the GC, such as the Java Virtual Machine's garbage collector or the .NET Common Language Runtime's garbage collector.

GIS stands for Geographic Information System, a technology used to analyze, visualize, and interpret spatial data.

• GIS allows users to capture, store, manipulate, analyze, manage, and present spatial or geographic data.

• It is used in various industries such as urban planning, natural resource management, transportation, and emergency response.

• Examples of GIS software include ArcGIS, QGIS, and Google Earth.

LOD stands for Level of Detail.

• LOD is a term commonly used in computer graphics and 3D modeling.

• It refers to the amount of detail or complexity in a 3D model or scene.

• Different levels of detail are used to optimize rendering performance.

• For example, a high LOD may include all the intricate details of a model, while a low LOD may only include basic shapes.

• LOD is important for real-time applications like video games to maintain smooth frame rates.

• It can also be used in data vis...read more
