SYSTEM SOFTWARE LESSON 1  OBJECTIVES AT THE END OF THE LESSON, YOU CAN: 1. Describe system software and utility programs. 2. Identify the types of the operating system. 3. Demonstrate how to create a folder.  INTRODUCTION When you acquire a laptop, desktop computer, or smartphone, it usually has system software installed. System software consists of programs that control and maintain the computer's and its devices' operations. It is essential to transform user commands into a form the computer can understand. The primary component of system software is the operating system. COMPUTER OPERATING SYSTEM MOBILE OPERATING SYSTEM  SYSTEM SOFTWARE It is a type of background program that controls a computer system. It is the facilitator of application programs and the hardware of computer systems between the computer and the user. APPLICATION SOFTWARE These programs allow users to work on a particular job or task on a computer.  OPERATING SYSTEM Operating System (OS) is a program that manages the activities taking place in a computer system. It is a set of programs that contain commands and instructions that organize all computer hardware resources. FUNCTIONS OF AN OPERATING SYSTEM a. Interfacing and communicating with users - This is how the user and the computer communicate using the Graphical User Interface (GUI). b. Booting the computer - Is it a process of starting or restarting a computer c. Configuring devices - Device drivers are always needed. Sometimes it will be automatically installed when the user plugs their device into the computer.  FUNCTIONS OF AN OPERATING SYSTEM d. Managing and monitoring resources and jobs - Operating systems monitor their resources while it is running. - Operating systems manage the computer's resources like the software, disk, and memory to make it available when needed. e. File management - Operating systems keep track of the files stored on a computer so they can be retrieved when needed. f. Security - Operating systems use many security procedures to prevent unauthorized access to system resources.  DIFFERENCES AMONG OPERATING SYSTEMS The first operating system used a command line. Currently, operating systems are using GUI or Graphical User Interface. Command Line Graphical User Interface  TYPES OF OPERATING SYSTEMS a. Personal Operating Systems - Also known as Desktop Operating Systems - Used to be installed on a single computer b. Server Operating Systems - Also known as Network Operating Systems - Nestled on a network server to have multiple users access a network and the resources. UTILITY PROGRAMS These pieces of software accomplish a specific goal. Mostly it is managing or maintaining the computer system. Various utilities are built into the operating system to find files, backup files, view images, restore files, etc. It can be available as a stand-alone product like security suites (antivirus)  TYPES OF UTILITY PROGRAM a. Search Tools - Used to search for files on the user's storage device b. Diagnostic Programs - Used to evaluate the computer system and recommend fixing the errors found. c. Disk Management Programs - Used to diagnose and repair problems related to the user's hard drive d. File Compression Programs - Used to reduce the size of files to utilize the space on a storage medium. - Used to zip and unzip files e. Uninstall Utilities - Used to remove programs from the user's hard drive f. Cleanup Utilities - Used to delete temporary files g. Backup and Recovery Utilities - Used to backup and restore processes  FOLDER A folder is a virtual location for applications, documents, data, or other sub-folders. Folders help in storing and organizing files and data in the computer. The term is most commonly used with graphical user interface operating systems (Techopedia, 2022). Folders are metaphors for organizing files on a computer. They are similar in function to real-world physical computers. A computer folder's icon is represented using an image of an actual folder.  HOW TO CREATE A FOLDER?
