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
