Operating System (Os)
| An operating system, or "OS," is a software program that manages the resources of a computer. The operating system is responsible for managing the computer's memory, processors, and other hardware. It also provides a platform for running application programs. Most personal computers and workstations use a graphical user interface (GUI), which allows the user to interact with the computer using a pointing device, such as a mouse, to select commands and options from menus. The operating system also provides a command-line interface (CLI), which allows the user to type commands to control the computer. The first operating systems were created in the early 1960s. At that time, computers were large, expensive, and used by only a few scientists and engineers. These early operating systems were designed to run a single program at a time. As computers became more powerful and less expensive, they were used for more tasks, and operating systems were developed that could run multiple programs simultaneously. Today, there are many different types of operating systems, including Windows, macOS, Linux, and Android. Each operating system has its own strengths and weaknesses. |
