System Software

          End users use application software to accomplish specific tasks. For example, we use word processors to create letters, documents, and reports. However, end users also use system software. System software works with end users, application software, and computer hardware to handle the majority of technical details. For example, system software controls where a word processing program is stored in memory, how commands are converted so that the system unit can process them, and where a completed document or file is saved. System software is not a single program. Rather it is a collection or a system of programs that handle hundreds of technical details with little or no user inter vention. System software consists of four types of programs:


• Operating systems coordinate computer resources, provide an interface between users and the computer, and run applications.


• Utilities perform specific tasks related to managing computer resources. 


• Device drivers are specialized programs that allow particular input or output devices to communicate with the rest of the computer system. 


• Language translators convert the programming instructions written by programmers into a language that computers understand and process.

Automations and robotics

Automations and robotics refer to the use of technology to automate and perform tasks that were previously done by humans. Automation involves the use of software, machines, and other systems to perform tasks without human intervention. Robotics, on the other hand, involves the design and development of machines that can perform tasks autonomously or with limited human intervention. Automations and robotics are widely used in industries such as manufacturing, healthcare, transportation, and agriculture. In manufacturing, robots are used to perform repetitive and dangerous tasks, such as welding and painting. In healthcare, robots are used to perform surgeries and assist patients with mobility issues. In transportation, automated systems are used to control traffic flow and ensure the safety of drivers and passengers. In agriculture, robots are used to plant and harvest crops, reducing the need for manual labor. Advancements in technology have led to the development of more sophisticate...
