Study Notes

Computer Systems

The primary role of software in a computer is to perform specific tasks and operations.
The two main components of a computer are hardware and software.

Problem Solving

Large problems should be broken down into smaller, manageable parts.

Java Programming

Java programs are translated into a language that computers understand using a compiler.
The Java Virtual Machine (JVM) is used to execute Java bytecode on any device, allowing platform independence.
The Java Software Development Kit (JDK) includes the Java Runtime Environment (JRE), compiler, and other tools.
The purpose of an Integrated Development Environment (IDE) is to provide a comprehensive platform for writing, debugging, and testing Java programs.
The Java Runtime Environment (JRE) provides the necessary libraries and resources to run Java programs.
Errors in the source code of a Java program will result in compile-time or runtime errors.
The Java Software Development Kit (JDK) must be installed to develop and run Java programs.

Programming Fundamentals

A computer program is a set of instructions that a computer can execute.
The role of software in a computer is to provide instructions and perform specific tasks.
Programs are written in high-level languages, such as Java, which use English-like abbreviations to represent operations.
A compiler is used to translate high-level languages into machine code.
Java bytecode allows for platform independence and efficient execution.
The main role of a programmer is to design, write, and test computer programs.
High-level languages are known for being easier to read and write, and are further away from machine code.

System Examples

'Windows 10' and 'Microsoft Word' are examples of software applications.
A payroll system represents a software application that performs specific tasks, such as calculating salaries and taxes.
