All Flashcards
What is Binary Conversion?
Translating between decimal (base-10) and binary (base-2) representations.
What is Data Compression?
Reducing the number of bits needed to store or transmit data.
What is Lossless Compression?
Compression that allows the original data to be perfectly reconstructed.
What is Lossy Compression?
Compression that loses some data to achieve a smaller file size.
What is Data Analysis?
Examining data to identify trends, make connections, and solve problems.
What is Data Cleaning?
Making data uniform without changing its meaning.
What is Data Filtering?
Selecting specific data based on certain criteria.
What is Data Transformation?
Changing the format or structure of data.
What is the significance of 'context matters' in binary?
The same bits can represent different data types depending on interpretation.
What are overflow and rounding errors?
Errors due to bit limitations; overflow is when a number is too big, rounding when inexact.
What is the purpose of metadata?
Provides structure and organization to data; data about data.
How does data processing programs help?
Extracts information from data through filtering, transformation and manipulation.
How is binary conversion applied in real-world scenarios?
Translating human-readable data to computer-readable data and vice versa.
How is lossless compression applied in real-world scenarios?
Used for text files and software where no data loss is acceptable.
How is lossy compression applied in real-world scenarios?
Used for images, audio, and video where some data loss is acceptable for smaller file sizes.
How is metadata applied in real-world scenarios?
Organizing and managing digital files, such as images and documents.
How is data filtering applied in real-world scenarios?
Finding specific information from a database.
What is the definition of Data?
Raw facts and figures.
What is the definition of Bits?
Binary digits (0 or 1).
What is the definition of Number Base?
The base of a number system (e.g., 10 for decimal, 2 for binary).
What is the definition of Machine Code?
The language understood by computers.
What is the definition of Byte?
A group of 8 bits.
What is the definition of Hexadecimal?
Base-16 number system, often used for representing binary data more compactly.
What is the definition of Abstraction?
Hiding complex details.
What is the definition of Analog Data?
Continuous data.
What is the definition of Digital Data?
Discrete data.
What is the definition of Metadata?
Data about data.
What is the definition of Overflow Error?
When a number is too large to be represented.
What is the definition of Rounding Error?
When a number cannot be represented exactly.
What is the definition of Information?
Meaning derived from data.
