Study Notes

Information Systems

An information system collects, processes, stores, analyzes, and disseminates information for a specific purpose.
The purpose of information systems is to get the right information to the right people, at the right time, in the right amount, and in the right format.
Information systems are intended to supply useful information.

Data, Information, and Knowledge

Data: Raw, unorganized facts that need to be processed and organized to convey any specific meaning.
Data can be numbers, characters, and currency amounts.
Information: Data that is processed and organized to convey meaning and value to the recipient.
Knowledge: Data and/or information that have been organized and processed to convey understanding and accumulated learning, and expertise as they apply to a current business problem.

Components of Information Systems

The five fundamental components of computer-based information systems that interact to produce information are:
- Hardware (information technology)
- Software (information technology)
- Data (information technology)
- Procedures
- People (users)

Hardware and Software

Hardware: Devices such as processors, monitors, keyboards, and printers that accept, process, and display data and information.
Software: A program or collection of programs that controls and coordinates the hardware.
Operating System: A program that controls the computer's resources, such as Windows and Linux.
Application software: Programs that run on top of the operating system and perform a business function.

Computer Components

CPU: The central processing unit, responsible for selecting instructions, processing them, performing arithmetic and logical comparisons, and storing results of operations in memory.
Main Memory (RAM): Circuitry for storing data and instructions that are acted upon by the CPU.
Special Function Cards: Cards that add to the computer to augment its basic capabilities.
