Study Notes

Computing Devices

A computer is an electronic device that can perform calculations and is used for various tasks
Types of computers include general-purpose computing devices and specific-purpose computers, as well as devices with computers inside

Command-Line Interface

A command-line interface (CLI) allows users to interact with the operating system using commands
Examples of CLIs include PowerShell (Windows) and Terminal (macOS/Linux)
Users can use commands to navigate and manage files and folders

File Structures and Paths

A tree pattern is used to organize files and folders on a computer
The root directory is the top-most level of the file system
Drives and discs have a drive letter designation (e.g. C:, D:, etc.)
Windows has a default location for installing programs (C:\Program Files for 64-bit applications and C:\Program Files (x86) for 32-bit applications)
User files are typically stored in the C:\Users\ directory (Windows) or Home folder (macOS/Linux)

Operating System

An operating system (OS) controls the computer hardware and enables users to interact with the computer
Examples of operating systems include Windows, macOS, and Linux
The OS provides a user interface (UI) and allows users to add, move, and delete programs and data
The OS also provides security features to protect the system from threats

Computing Process

The computing process consists of three stages: input, processing, and output
Input: getting data into the computer using devices like the mouse, keyboard, and touch screen
Processing: the OS tells the hardware what to do using the central processing unit (CPU)
Output: displaying the results on the monitor or through speakers
Additional stages include data storage and network connection

Hardware and Software

Hardware refers to the physical components of a computer, such as the keyboard, monitor, and CPU
Software refers to the programs and operating system that run on the computer
Applications (programs) allow users to perform specialized tasks on a computer
