Study Notes
Chapter 6: Software Development
-
Exam Objectives Covered: 1.1 Compare and contrast notational systems, 1.2 Compare and contrast fundamental data types, 4.1 Compare and contrast programming language categories, 4.2 Use programming organizational techniques and interpret logic
-
1.1 Notational Systems:
- Binary (base-2) uses 1s and 0s
- Hexadecimal (base-16) uses 0-9 and A-F
- Decimal (base-10) uses 0-9
- Data representation is crucial in computer science
- ASCII (American Standard Code for Information Interchange) represents characters using numerical codes
- Unicode provides a broader set of characters, including many non-English characters
-
1.2 Fundamental Data Types:
- Char represents one character
- Strings are sequences of characters enclosed in quotes
- Numbers are for numerical data
- Integers are whole numbers
- Floats are numbers with decimals
- Boolean represents true or false values (1 or 0)
-
4.1 Programming Language Categories:
- Interpreted languages run instructions one at a time
- Scripting languages are for automating tasks or quick scripts
- Compiled languages translate entire code into machine code, which runs very quickly
- Query languages are designed to pull information from databases efficiently
-
4.2 Programming Organizational Techniques:
- Organizational techniques are necessary for large programs
- Pseudocode and flowcharts are used to visualize and organize
-
4.3 Programming Concepts:
- Pseudocode and flowcharts as mentioned above allow developers to organize code.
- Identifiers
- Variables
- Constants
- Containers
- Arrays
- Vectors
- Functions
- Objects
- Properties
- Attributes
- Methods
Additional Concepts
- Binary: The base-2 numbering system used by computers (1s and 0s) is essential for understanding how computers process data
- Hexadecimal: A base-16 numbering system frequently used in programming and digital technology, often for representing colors, addressing memory locations, and so on.
- Data Types: Understanding data types (integer, float, string, Boolean, char) is critical when writing programs.
- Programming Languages: This page describes high-level (compiled and interpreted) languages, which are easier to use than assembly (low level), which deals directly with the computer hardware more efficiently.
- Programming Logic: Understanding how programs make decisions (branching, conditional statements) and repeat tasks (loops) is crucial when constructing complex programs. The difference between
if,else if, andelsestatements are part of making complex choices. - Containers: Arrays, vectors, and other structures for storing and managing large amounts of data
- Functions and Methods: Code blocks that perform specific tasks
- Objects and Classes: OOP concepts for grouping data and behavior together
- Organizational Techniques: Flowcharts and pseudocode for planning and visualizing program flow
- Query Languages: Special languages, like SQL, for interacting with data stored in databases
