Study Notes
Software Resources
- Software can be categorized into two types: Systems Software and Application Software.
- Systems Software manages and controls the operation of the computer system, performing tasks on behalf of the user.
- Application Software enables users to perform specific information-processing activities.
Categories of Systems Software
- Operating System software manages and controls the operation of the computer system.
- Software Development Programs allow users to develop their own software to carry out processing tasks.
- Utility Programs provide a range of tools that support the operation and management of a computer system.
Software Development Programs
- First Generation languages require a programmer to work in ones and zeros to represent characters and numbers.
- Second Generation languages use assembly language, which simplifies the tasks.
- Third Generation languages, such as FORTRAN, EGO, and BAST, make producing code easier.
- Fourth Generation languages, such as SQL, are built around a database system and make producing code even easier.
Utility Programs
- Examples include programs that monitor system performance, provide security controls, antivirus software, backup software, and disk tools.
Network Components
- Server controls the flow of information around the network, manages network resources, and uses a Network Operating System (NOS).
- End-user Computers or Terminals are also known as clients, nodes, or workstations, and are the access point for users of a network.
- Telecommunications Processors are pieces of hardware that link street networks together, including Hubs, Routers, Firewall, and Middleware.
Advantages and Disadvantages of Networking
- Advantages:
- Allows people to collaborate
- Allows hardware to be shared more cost-effectively
- Helps businesses connect with customers, suppliers, and collaborators
- Reduces costs through the use of facilities such as email
- Reduces time for information flow
- Allows sharing information by accessing a database over a network
- Disadvantages:
- Cost of installing and ensuring a secure and reliable network service
Characteristics of Valuable Information
- Accurate: error-free, dependent on the reliability of data collection, methods, and data source.
