Study Notes
Introduction to ITEPLF
- A computer system is a combination of hardware and software used to process and store data.
- Hardware refers to the physical components of a computer system, such as keyboards, monitors, and the Central Processing Unit (CPU).
- Software consists of instructions that tell the hardware what to do, these are written by programmers.
- Software can be classified into system software, which manages the computer's hardware, and application software, which helps users perform specific tasks.
Basic Computer Operations
- A computer system performs four main operations: input, process, output, and storage.
- Input involves receiving data into the computer system through hardware such as keyboards or mice.
- Processing transforms input data using the CPU, which can include calculations, organization, and validation.
- Output displays the processed information to users via devices like monitors or printers.
- Storage involves storing data temporarily or permanently, which is facilitated by hardware components like RAM or hard drives.
History of Computer Programming
- Computer programming is the process of designing, writing, testing, debugging, and maintaining computer programs.
- Programming languages act as a means of instructing a computer to perform tasks and provide a framework to organize ideas.
- Ada Lovelace is widely regarded as the first computer programmer for her work on algorithms for Charles Babbage's Analytical Engine.
- Konrad Zuse was the first to successfully run a program on a modern electronically based computer in 1941.
- The ENIAC programming team comprised the first group of regular programmers.
Programming Languages
- Programming languages are divided into generations, with 3GLs (Third-generation languages) being more high-level than 2GLs, and 4GLs being even easier to use.
- Examples of 4GLs include Visual Basic, Visual C#, NetBeans Java, and Prolog.
- Programming languages have vocabulary, which includes data types, logic, and machine code; syntax, which defines the rules for combining words into statements; and semantics, which defines the meaning of those statements.
Programming Errors
- Programming errors are commonly known as bugs, and the process of finding and fixing them is called debugging.
- There are three common error types: syntax errors, runtime errors, and logic or semantics errors.
- Syntax errors occur when programming language syntax rules are violated, and are typically detected by the compiler or interpreter.
- Runtime errors happen during program execution and can cause crashes, often due to illegal actions requested by the program.
- Logic or semantics errors are harder to find, as the program compiles and runs without errors but doesn't produce the intended outcome.
