Operating Systems

Windows Operating System Features

The management of operating systems involves functions to control the operation of internal devices and computer peripherals, providing access to the disk to read or store information in an organized way and to install and run application programs. One of the most widespread is the Windows operating system. It provides a user-friendly graphical interface that allows the simultaneous execution of multiple applications.

• The Windows Desktop: This is the primary workspace.
• Windows Explorer: An essential utility to access folders and files.
• Control Panel: Allows access to different tools to configure the operation of equipment.
• Hardware and Software: It permits adding hardware or adding and removing programs using wizards.
• System Utilities: Provides tools to configure system utilities and general characteristics of programs.
• General Settings: It permits modifying settings such as date and time.
• Device Configuration: Provides access to device configuration.
• User Management: Facilitates managing user accounts.

Linux Operating System and Distributions

The Linux operating system is licensed as free software, so there are different distributions or versions of it. The Linux kernel offers an operating system command interface that, once booted, can load a multiprocessing graphical environment.

• Linux Desktops: These are the usual elements of a graphical environment.
• Nautilus File Browser: Accesses the folder tree for managing the archiving of documents. It identifies diskette drives, floppy disks, and their partitions (e.g., hda, hda1, hda2).
• Machine Configuration: The Linux configuration can be modified through the control panel.
• Desktop Customization: Personalize the desktop configuration.
• Peripheral Control: Configure keyboard controllers, mouse, and other peripherals.
• Network Connectivity: Access devices for telematic network connectivity.
• System Properties: Examine and modify properties of the system.
