Study Notes
Human-Computer Interaction (HCI)
Definition
- HCI is the study of how people interact with computers and design of computers that are easy to use and provide a good user experience.
Goals of HCI
- Improve user experience and satisfaction
- Increase productivity and efficiency
- Enhance accessibility for people with disabilities
Principles of HCI
- User-centered design: design systems around the needs and abilities of users
- ** Visibility**: make system status and functionality visible to users
- ** Affordance**: design systems to suggest their functionality
- ** Feedback**: provide users with feedback about their actions
- ** Consistency**: use consistent design elements throughout the system
HCI Design Process
- Analysis: understand user needs and goals
- Design: create prototypes and design solutions
- Implementation: build the system
- Evaluation: test and refine the system
Operating Systems (OS)
Definition
- An OS is a software that manages computer hardware resources and provides common services to computer programs.
Functions of an OS
- Process Management: manage creation, execution, and termination of processes
- Memory Management: manage main memory and virtual memory
- File Management: manage file systems and storage devices
- I/O Management: manage input/output operations
- Security: manage access control and protection of system resources
Types of OS
- Single-User Single-Tasking OS: one user, one task (e.g., MS-DOS)
- Single-User Multi-Tasking OS: one user, multiple tasks (e.g., Windows)
- Multi-User OS: multiple users, multiple tasks (e.g., Unix)
OS Components
- Kernel: core of the OS, manages hardware resources
- Device Drivers: software that controls hardware devices
- System Libraries: provide common functions for applications
- System Utilities: programs that perform maintenance and management tasks
