Study Notes
Information Systems
- Information systems (IS) are integral to daily life, facilitating tasks such as class registration, bill payments, job searches, and travel bookings.
- Operating systems, like Windows 8 and Mac OS X, coordinate computer resources and serve as the user interface.
- Utilities, particularly antivirus programs, are essential for protecting systems from viruses and malicious software.
Application Software
- Application software is categorized into three types:
- General-purpose applications are widely utilized across various fields, essential for computer competency (e.g., web browsers like Firefox, Internet Explorer, and Chrome).
- Specialized applications target specific disciplines or occupations (e.g., graphic design software).
- Mobile applications are designed for mobile devices, with a vast array of over half a million available, focusing on messaging, browsing, and social networking.
Types of Computers
- Supercomputers are the most powerful and primarily used by large organizations (e.g., IBM's Blue Gene).
- Mainframe computers are capable of high processing speeds and data storage, commonly used by insurance companies to handle vast amounts of data.
- Midrange computers (servers) serve medium-sized companies or departments, facilitating data retrieval and application access.
-
Microcomputers are the fastest-growing type and include four subcategories:
- Desktop computers are designed for stationary use.
- Notebook computers (laptops) are portable and lightweight.
- Tablets are smaller and lighter than laptops, with reduced power (e.g., Apple’s iPad).
- Handheld computers, including PDAs and smartphones, are designed for single-handed operation.
Computer Hardware
- System unit: Enclosure containing essential electronic components of a computer.
- File types created by different applications:
- Document files (e.g., memos, term papers).
- Worksheet files for analysis (e.g., budgets, forecasts).
- Database files store highly structured data (e.g., employee information).
- Presentation files include materials for presentations (e.g., handouts, slides).
Connectivity
- Networks connect multiple computers, with the Internet being the largest global network, enabling communication and resource sharing.
- The web serves as a multimedia interface for accessing Internet resources.
- Cloud computing shifts computing activities from personal devices to Internet-based servers, enhancing efficiency and resource utilization.
