- System software is the set of programs that helps run the computer and coordinates instructions between application software and the computer's hardware devices. System software consists of two primary types of programs: the operating system and utility programs. The operating system (OS) is a group of programs that controls how your computer system functions. The operating system is responsible for the management, scheduling, and coordination of tasks; manages the computers hardware; and provides a consistent means for software applications to work with the CPU. System software also includes utility programs. A utility program is a small program that performs many of the general housekeeping tasks for the computer, such as system maintenance and file compression. (ex. diagnose a problem and recover files)
2. What are the different kinds of operating systems?
- Operating systems can be categorized by the type of device in which they are installed, such as robots and specialized equipment, mainframes and network computers, mobile devices, and personal computers.
- Real-time operating systems (RTOS)
- Multiuser operating system (network operating systems)
3. What are the most common operating systems?
- The most common operating systems are:
- Unix- multiuser/multitask OS
- MS-DOS (first OS) single user/single task needed to type specific commands
- Mac OS- first to incorporate a graphical user interface (GUI) and user friendly point-and-click technology
- Linux- open source OS designed for use on personal computers and as a network OS; it is freely available for developers to use or modify as thy wish
4. What is Jing?
- Jing is a free Web service that allows users to take screenshots/ images on the computer screen; when you take a screenshot you can add text to the image. You can select any window or region that you would like to record, and Jing will capture everything that happens in that area. From simple mouse movements to a narrated video. Jing can also help you create videos. These screenshots and videos are great for businesses and schools. Its great for students to ask their teachers questions and show the teacher exactly where they are having the problem. in class we actually had something similar to this. We opened a file with a screenshot of a list of document files and were told to fill in the text boxes with what each area was called. I think this is great for schools to use in the classroom. Like the example I gave it can help create study guides and even tests. I personally do not think I would use it, but do think it is great idea!
