Structured, Semi-structured, and Unstructured Data
Structured data, like an Excel spreadsheet, is organized in rows and columns. Unstructured data, such as images, lacks this tabular structure. Semi-structured data, including JSON and XML, falls in between. It doesn’t strictly adhere to the tabular format but uses tags or markers to separate elements and enforce hierarchies. JSON, or JavaScript Object Notation, is a common example, using attribute-value pairs.

Hydropneumatic Suspension
This system provides great flexibility and regulates body height independently of the vehicle load.
Advantages:
- Offers comfort
- Maintains correct body height
- Regulates the lower center of gravity
- Improves suspension in a vacuum
- Allows height adjustment of the body
- Provides better safety in case of a puncture
- Reduced maintenance
Hydraulic Suspension
This system transmits and ensures fluid motion as the union of mobile elements within pipelines. Gas replaces mechanical spring suspension,

1. Introduction to Gas Turbine Engines
1.1 Brayton Cycle
The Brayton cycle is a continuous combustion cycle.
1.2 Jet Engines vs. Rocket Engines
Rocket Engines:
- Carry their own fuel and oxidizer.
- Do not require atmospheric air for combustion.
Jet Engines:
- Use atmospheric air for combustion.
- Share the same principle of operation as rocket engines (action/reaction).
Key Difference: The primary difference lies in the source of the oxidizer.
1.3 Jet Engine and Turbofan Engine Characteristics
True Statement: The

Multimedia Data
Multimedia data is an interactive way to represent information to a user. It includes several categories of data like textual data, audio data, video data, etc. The database which is used to hold these different kinds of multimedia data is known as a multimedia database. Nowadays, we as a user take the help of various forms of media such as text, images, audio, video, and graphic objects for communication or to gain any kind of information. These media forms are collectively known
