Study Notes
Introduction to Computers and Programming
- People use computers at school, work, and home for various tasks such as writing papers, analyzing data, making presentations, and communicating.
- Devices that are considered computers include smartphones, iPods, tablets, and car navigation systems.
Programmers and Software
- A program is a set of instructions that a computer follows to perform a task.
- Programmers or software developers create computer software.
- Software is commonly referred to as programs.
Hardware and Software
- Hardware refers to the physical devices that a computer is made of.
- A computer system consists of a central processing unit (CPU), main memory, secondary storage, input devices, and output devices.
- The CPU, also known as the processor, runs the programs.
CPU and its Functions
- The CPU is the most important component in a computer.
- CPU is not smart, it's an electronic device designed to perform specific tasks.
- CPU's functions include reading data from main memory, performing arithmetic operations, and moving data between memory locations.
How a Program Works
- Key words or reserved words have specific meaning and purpose in a programming language.
- Operators perform various operations on data.
- Syntax is a set of rules that must be strictly followed when writing a program.
- Statements are individual instructions written in a programming language.
Compilers and Interpreters
- Source code is translated to machine language using a compiler or an interpreter.
- A compiler is a program that translates a high-level language program into a separate machine language program.
- An interpreter is a program that both translates and executes the instructions in a high-level language program.
Types of Software
- Programs generally fit into one of two categories: system software and application software.
- System software controls or enhances the operation of a computer, including operating systems, utility programs, and software development tools.
- Application software makes a computer useful for everyday tasks, including Microsoft Word, email programs, and web browsers.
