Study Notes
Computer Architecture Basics
- Computer architecture encompasses the rules and methods that define the functionality and organization of computer systems.
- Key components of computer architecture include:
- Instruction Set Architecture (ISA): Defines what a computer can do (logical view).
- Computer Organization: Describes how the ISA is implemented (physical view).
- Equation: Computer Architecture = Computer Organization + Instruction Set Architecture.
Understanding Data
- Data is defined as known facts used for reasoning and calculations, often represented as unorganized elements like alphabets, numbers, or symbols.
- In 2011, approximately 1.8 trillion gigabytes of data were created, which increased to over 2.8 trillion gigabytes in 2012.
- Projected data creation could reach 40 trillion gigabytes in 2020.
- Data can have both quantitative and qualitative aspects and can originate from various sources like forms, observations, and occurrences.
Data Storage and Retrieval
- NoSQL databases are recommended for handling large volumes of data that traditional relational databases may struggle with.
- Data lakes accommodate diverse data sources and formats, providing flexibility in data structure compared to traditional systems.
Data Representation in Computing
- Data representation can include:
- Numbers from spreadsheets.
- Text characters in documents.
- Image pixels, where an image is composed of individual pixels (Picture Elements).
- For example, a 1020 x 800 image resolution results in 816,000 total pixels.
Example Calculation for Images
- Consider an image with 3072 pixels by 2304 pixels:
- Total pixels: 7,059,456.
- Required calculations can include file size and storage capacity for memory cards.
Data in Sound Processing
- MP3 audio playback involves reading numbers from the disk, manipulating them to convert compressed data into a raw audio format for output.
- The manipulation of numbers is essential for audio data processing.
Computer System Composition
- A computer system consists of multiple memory types for program storage and data manipulation during processing.
- Input and output devices facilitate interaction with the computer, including keyboards for text input and screen displays for information output.
Key Takeaways for Study
- Focus on understanding the relationship between data, architecture, and organization within computer systems.
- Recognize the growing significance of data management, storage solutions, and efficient data processing techniques.
- Practice mathematical calculations related to pixels and data sizes to strengthen your understanding of data representation.
