Study Notes
Computer Systems
- A computer is a machine that can perform tasks automatically and sequentially.
- Data processing in a computer system involves input, manipulation, output, and storage.
- A computer system consists of two main components: hardware and software.
- Hardware refers to the physical equipment.
Programming and Logical Problem Solving
- Problem-solving in IS&T is essential for developing programs.
- Programs are sets of instructions that enable computers to perform tasks.
- To solve a problem, we define the problem precisely, design an algorithm, and implement the solution using a programming language.
Syntax
- Syntax refers to the rules and grammar of a programming language, which governs how statements are formulated.
- Each programming language has its own syntax that determines the expected format of code.
- Computers understand code only if it's written in the correct syntax.
Elements of a Programming Language
- Programming languages have fundamental elements like data types, variables, keywords, operators, decisions, loops, functions, and more.
Compilers and Interpreters
- Computers understand machine code (binary patterns), which is different from human-readable languages.
- Compilers translate entire programs from human-readable source code into machine code.
- Interpreters execute code line by line, translating and running a program piece by piece.
- Compilers and interpreters are tools that help bridge the gap between human languages and machine languages.
GIGO (Garbage In Garbage Out)
- The accuracy of computer output depends on the correctness of input provided.
- GIGO highlights that computers process input unquestioningly, so incorrect or nonsensical input can result in erroneous output.
The Programming Process
- The programming process helps create programs that meet specific requirements.
- It involves a series of steps, such as defining the problem, designing an algorithm, and writing and testing code.
- There are various programming methodologies and processes followed in industry, some of which are covered in advanced ISTN courses.
- A simple programming process involves defining the problem, developing an algorithm, implementing the algorithm using a programming language, and testing the program.
Problem Definition
- Break down a problem into input, output, and processing steps.
- Input defines what data is entered into the program.
- Output specifies the desired results or answers the program should provide.
- Processing steps outline the actions the program takes to transform input into output.
