Study Notes
Introduction to Computer Science
- The future of computers and digital technology promises exciting challenges and opportunities.
- The chapter introduces the skills and concepts needed to be prepared for the ever-changing digital world.
Information Systems
- An information system consists of six parts: people, procedures, software, hardware, data, and internet.
- People are the most important part of an information system.
- People interact with computers directly (e.g., using a word processing program) and indirectly (e.g., using computers in medicine, entertainment, education, and business).
Procedures
- Procedures are the rules or guidelines for people to follow when using software, hardware, and data.
- Procedures are typically documented in manuals written by computer specialists.
Software
- Software is another name for programs.
- Programs consist of step-by-step instructions that tell the computer how to do its work.
- The purpose of software is to convert data into information.
- There are two major kinds of software: system software and application software.
System Software
- System software is a "background" software that helps the computer manage its own internal resources.
- System software enables applications to interact with the computer hardware.
- System software includes operating systems and utilities.
- Operating systems coordinate computer resources, provide an interface between users and the computer, and run applications.
- Examples of operating systems include Windows and Mac OS.
- Utilities perform tasks related to managing computer resources, such as antivirus programs.
Application Software
- Application software might be described as end-user software.
- Application software types include:
- General-purpose applications (e.g., browsers, Word processor, spreadsheet)
- Specialized applications (e.g., graphics and Web authoring programs)
- Mobile apps (mobile applications)
Hardware
- Hardware is the equipment that processes data to create information.
- Hardware includes smartphones, tablets, keyboards, mice, displays, system units, and other devices.
- Hardware is controlled by software.
- There are four types of computers:
- Supercomputers (the most powerful)
- Mainframe computers (not as powerful as supercomputers, but capable of great processing speed and data storage)
- Midrange computers (also referred to as servers, with processing capabilities less powerful than a mainframe computer but more powerful than a personal computer)
- Personal computers
Connectivity and the Mobile Internet
- Almost all information systems provide a way to connect to other people and computers, typically using the Internet.
- Connectivity is the capability of a personal computer to share information with other computers.
- A network is a communications system connecting two or more computers.
- The largest network in the world is the Internet.
- The web provides a multimedia interface to the numerous resources available on the Internet.
- Cloud computing, wireless communication, and the Internet of Things (IoT) are driving the impact of technology on our lives.
Learn about system software, which is a background software that helps the computer manage its own internal resources and enables applications to interact with the computer hardware.
