Operating Systems and Utility Programs

[Audio] GOOD DAY EVERYONE I'M GONNA PRESENT TO YOU ALL ABOUT Operating Systems and Utility Programs. I AM JOANNA GRACE B. BERMUDEZ, YOUT PRESENTER FOR TODAY'S TOPIC.

[Audio] Objectives Define system software and identify the two types of system software. Describe each of the functions of an operating system. Identify and familiarize the three types of operating systems. Describe the purpose of several utility programs.

[Audio] Operating Systems and Utility Programs System software is a type of computer program that is used to run the hardware and application programs on a computer. System software serves as the interface between hardware and user applications. The most well-known example of system software is the operating system, or computer operating system..

[Audio] Operating System ( OS) – An operating system is a piece of software that handles all of the fundamental tasks such as file management, memory management, storage management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers. The operating system serves as a bridge between the user and the hardware, allowing computer hardware and software to interact..

[Audio] Operating System Functions. Operating System Functions.

[Audio] 1. DEVICE MANAGEMENT – Operating System manages device communication via their respective drivers. It does the following activities for device management − Keeps tracks of all devices. I/O controller is responsible for this task Decides which process gets the device when and for how much time. Allocates the device in an efficient way. De-allocates devices. FILE MANAGEMENT – The collective facilities are frequently referred to as a file system. It specifies which process receives the file and for how long. It also keeps track of information, location, uses, status, and so on. OS also creates directories and files, copies and moves them, and renames and deletes them..

[Audio] MEMORY MANAGEMENT – Memory Management is the process of controlling and coordinating computer memory, assigning portions known as blocks to various running programs to optimize the overall performance of the system. It is the most important function of an operating system that manages primary memory. PROCESS MANAGEMENT – Process management involves various tasks like creation, scheduling, termination of processes, and a dead lock. Process is a program that is under execution, which is an important part of modern-day operating systems. The OS must allocate resources that enable processes to share and exchange information.

[Audio] MASTERMIND – An operating system is a term that can be used correctly. It performs a plethora of functions that can only be performed by a super-intelligent mind. STORAGE MANAGEMENT Storage management refers to the software and processes that improve the performance of data storage resources. It may include network virtualization, replication, mirroring, security, compression, deduplication, traffic analysis, process automation, storage provisioning and memory management..

[Audio] The diagram shows the operating systems and its functions. How system and hardware works by the time the user uses the operating system..

[Audio] Types of operating systems Modern operating systems use a graphical user interface, or GUI (pronounced gooey) A GUI lets you use your mouse to click icons, buttons, and menus. Each operating system has a different look and feel, so if you switch to a different one it may seem unfamiliar at first. Microsoft Windows (also referred to as Windows or Win) is a graphical operating system developed and published by Microsoft. It provides a way to store files, run software, play games, watch videos, and connect to the Internet..

[Audio] macOS is the operating system that powers every Mac. It lets you do things you simply can't do with other computers. That's because it's designed specifically for the hardware it runs on — and vice versa. macOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents and other stuff up to date on all your devices. It makes your Mac work like magic with your iPhone and other Apple devices. And it's been built from the ground up with privacy and security in mind. Linux is a family of open-source operating systems that can be modified and distributed by anyone. The advantages of Linux are that it is free, and there are many different distributions you can choose from. According to StatCounter Global Stats, Linux users account for less than 2% of global operating systems..

[Audio] Utility software is system software that aids in the proper and efficient operation of a computer system. It aids the Operating System in managing, organizing, maintaining, and optimizing the computer system's operation..

[Audio] Types of Utility Software Antivirus A virus is a malicious software that enters the system along with a host program. Moreover, it multiplies with time and makes several copies which in turn slows down and corrupts the system. Examples of antivirus are McAfee Antivirus, Quickheal Antivirus, Windows Defender, etc. File Management System These utility software are used to manage files of the computer system. Since files are an important part of the system as all the data is stored in the files. Therefore, this utility software help to browse, search, arrange, find information, and quickly preview the files of the system. Google Desktop, Double Commander, Directory Opus.

[Audio] Compression Tools An important part of a computer is storage space, it is very important to maintain this storage. Therefore, we use certain utility software to compress big files and decrease size, these are compression tools. Examples of compression tools are WinZip, WinRAR, WinAce, PeaZip, 7-Zip. Disk Management Tools These utility software are used to manage data on disks. Moreover, they perform functions like partitioning devices, manage drives, etc. Examples of disk management tools are MiniTool Partition Wizard, Paragon Partition Manager..

[Audio] Disk Cleanup Tool This utility software helps to free up the disk space. In addition, the files which are no longer in use are removed from the disk. Examples are Razer Cortex, Piriform CCleaner, Disk Defragmenter This utility software helps to reduce the fragmentation and hence, reduces the access speed. Defragmenting refers to rearranging files and storing them in contiguous memory locations. Moreover, saves time in reading from files and writing files to disk. Examples of disk defragmenters are Perfect disk, Deflaggler Backup Utility This utility software helps to back up the files, folders, databases, or complete disks. Moreover, backup refers to duplicating the disk information so that the data can be restored if any data loss happens. Examples are Norton Ghost, Symantec Backup Exec.

[Audio] Advantages of Utility Software Enhances performance. Manages space. Manages files and data. Helps to customize interface and desktop. Helps to remove useless files. Keep the system safe and secure. Helps to recover files after a loss..
