Study Notes
Programming for Problem Solving - Unit 1
- A computer system is made up of hardware and software
- Computer hardware includes input devices, CPU, output devices, memory, and storage devices (e.g., hard disk, flash, SD, RAM)
- Computer software includes system software (operating system, system support, system development) and application software (general purpose, application specific)
Computer Hardware
- Hardware refers to physical components
- Essential for creation, use, manipulation, and storage of electronic data
- Five main parts:
- Input devices: Keyboard, mouse, scanner
- CPU: Central Processing Unit (executes programs)
- Output devices: Monitor, printer, plotter
- Memory: RAM and ROM
- Storage devices: Hard disk, flash drive, SD card, etc
Computer Architecture (Block Diagram)
- Shows the relationship between components
- Input devices (data) feed to the CPU
- CPU includes ALU (arithmetic logic unit) and CU (control unit)
- Memory Unit holds data for processing
- Output devices (information) receive output from the CPU
Computer Software
- Programs to achieve tasks
- Programming languages: Set of rules, vocabulary, and syntax
- System software: Manages hardware and software resources (operating systems, support software, development tools).
- Application software: Solves specific problems (general purpose apps, special purpose software).
- Examples: word processors, web browsers, accounting software.
Computing Environments
- Various ways computers work together
- Personal computing: Single computer
- Time-sharing: Many users share a single CPU
- Client-server: Central server and multiple clients (shared resources)
- Distributed computing: Integrating multiple clients and servers across networks
- Cloud computing: Computing from a cloud of computers (Software as a service, Infrastructure as a service, Platform as a service)
- Cluster computing: Multiple computers working together
Data Representation
- Bit (binary digit): Smallest data unit (0 or 1).
- Bit pattern (sequence of bits).
- Byte: 8-bit pattern
- Number systems: Decimal, binary, octal, hexadecimal
Computer Languages
- Machine language (0s and 1s)
- Symbolic language: Using symbols (mnemonics) to represent machine instructions
- High-level languages: Closer to natural language, require translation (e.g., C++, Java, Python)
Creating & Running Programs
- Writing and Editing: Creating the source code.
- Compiling: Translating high-level code into machine code.
- Linking: Connecting program code with system libraries.
- Executing: The program runs.
Program Development
- Understanding the problem
- Developing a solution:
- Structure chart
- Algorithm/Pseudo code
- Flowchart
- Writing the program
- Testing the program
Algorithm
- A set of steps to solve a problem
- Precise definition
- Must be unambiguous and clearly defined
- Halts in a finite time
- Uses ordered sets of steps to solve a well-defined problem.
Flowchart
- Graphical representation of an algorithm
- Using standardized symbols to represent actions and decisions
- Depicts the flow of a process.
Types of Algorithmic Operations
- Sequential operations: Process single steps in order.
- Conditional operations: Making decisions using "if-then-else" blocks.
- Iterative operations: Repeating steps using loops.
