Systems software is software that provides a platform for other software and manages the basic functions of a computer. Examples of systems software include operating systems, device drivers, firmware, utility software, and boot loaders. Operating systems are the most important type of systems software, as they provide the foundational framework for all other software and applications to run on the computer. Linux and Unix are examples of operating systems that are widely used in various domains, such as servers, desktops, embedded systems, and supercomputers. Device drivers are another important type of systems software, as they allow the operating system to communicate with hardware devices such as printers, scanners, and graphics cards. A device driver is a software component that acts as an interface between the hardware and the operating system, providing the necessary commands and data to control the device. Internet Explorer and Adobe Photoshop are not examples of systems software, but application software. Application software is software that allows users to perform specific tasks, such as browsing the web, editing images, creating documents, or playing games. Application software runs on top of the systems software and uses the services and resources provided by the operating system and the hardware. References: System software - Wikipedia, What is System Software? – Definition, Types, Examples and More, What is System Software: Definition, Types, Language Processors - Toppr.

Organizations are linked extensively to increase their efficiency and effectiveness in achieving their goals. By reducing cycle times, organizations can deliver their products or services faster and more responsively to their customers. By improving accuracy, organizations can reduce errors, waste, and rework, and enhance their quality and reliability. These outcomes can also increase the capability of the organization to meet the changing needs and expectations of the market and the stakeholders. References: Sample Exam - GAQM, page 1, question 1; The Future of Flexibility at Work, paragraph 4.

 Distributed databases provide several advantages over centralized databases, including improved scalability, availability, performance, flexibility, fault tolerance, and security1. Here are some of the advantages of distributed databases:

• Increased availability: Distributed databases can tolerate failures of individual nodes or sites without affecting the overall system functionality. Users can access data from other sites if their local site is down or unreachable. Data replication and backup mechanisms can also enhance data availability and recovery2.
• Easier expansion: Distributed databases can be scaled horizontally by adding more nodes to the network. This allows for increased capacity and performance as data and user demand grow. Adding new sites or units to the distributed system does not require significant efforts or disruption in the existing functions2.
• Improved performance: Distributed databases can offer faster response and lower communication costs by locating data near the users who normally use that data. Distributed query processing and transaction management can also optimize the use of network and computing resources. Furthermore, distributed databases can exploit the parallelism of multiple nodes to execute operations concurrently13.
