Operating Systems by FERNANDO BERMÚDEZ FULLEA https://padlet.com/1920165/b6vd5eisfoqjjkn8 Hey! This is my Padlet, here I'll talk about operating systems, what are they and some examples. Hope you like it! en-us 2020-11-23 09:36:57 UTC 2025-09-28 21:10:50 UTC hello@padlet.com https://padlet.net/icons/png/1f5a5.png What is an Operating System? 1920165 https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/951668925 An operating system, or "OS," is software that communicates with the hardware and allows other programs to run. It's also act as the interface between the user and the computer.
Every computer, tablet, and smartphone includes an operating system that provides basic functionality for the device.
You can use it or not.

There are two main parts to an operating system, the kernel and the user space. 

When we say operating system, we're talking about both the kernel and the user space.

But the ones most common are these six:
  • Microsoft Windows. The most popular one for home and office computers, targeted to Intel architecture based computers. Created by Bill Gates.
  • Apple iOS.  One of the most popular smartphone operating systems, second only to Android. 
  • Android.  Android is the most popular operating system in the world.Largely developed by Google. Unlike iOS, it can be used on devices made by a variety of different manufacturers, and those makers can tweak parts of its interface to suit their own needs.
  • Apple MacOS.  Runs on Apple laptops and desktops, safe data privacy. Created by Steve Jobs. 
  • Linux. Open license model, so its code is able to be modificated, utilized and redistributed freely. Variety of devices: from computers to smart-watches. Origin in Unix.
  • Ubuntu. One of Linux's modification, and the most popular one among them.

  1. Process management: helpsthe  OS to create and delete processes. It also provides mechanisms for synchronization and communication among them.
  2. Memory management: performs the task of allocation and deallocation of memory space to programs in need of this resources.
  3. File management: it manages all the file-related activities such as organization storage, retrieval, naming, sharing, and protection of files.
  4. Device Management: keeps track of all devices. It also performs the task of allocation and deallocation of the devices.
  5. I/O System Management: hide the peculiarities of that hardware devices from the user, which is  one of the main objectives of any OS to do.
  6. Secondary Storage Management: systems have several levels of storage which includes primary storage, secondary storage, and cache storage. Instructions and data must be stored in primary storage or cache so that a running program can reference it. 
  7. Security: protects the data and information of a computer system against malware threats.
  8. Command interpretation: interpret commands given by the and acting system resources to process that commands.
  9. Networking: a distributed system is a group of processors which do not share memory, hardware devices. The processors communicate with one another through the network. 
  10. Job accounting: keeping track of time & resource used by various job and users.
  11. Communication management: coordination and assignment of compilers, interpreters, and another software resource of the various users of the computer systems.

They exist two different types:
  1. Monolithic;  is a single code or block of the program with a simplistic design which creates a distinct communication layer between the hardware and software. 
  2. Microkernels;  manages all system resources. Services are implemented in different address space, so it helps to reduce the size of both the kernel and operating system.

Android: 38%
iOS: 16%
MacOS: 4%
Others: 2%]]> 2021-06-15 12:59:36 UTC https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/1607461493 User Space 1920165 https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/1607581344 The user space is everything outside the kernel. These are the things that we interact with directly like programs, such as text editors, music players, system settings, user interfaces, etc.
Each user space process normally runs in its own virtual memory space, and, unless explicitly allowed, cannot access the memory of other processes. ]]> 2021-06-15 13:46:24 UTC https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/1607581344 Virtual Memory 1920165 https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/1607598089  The use of virtual memory space  means that the kernel is allowed to choose the memory each program may use at any given time, allowing the operating system to use the same memory locations for multiple tasks.]]> 2021-06-15 13:52:35 UTC https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/1607598089 Drivers 1920165 https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/1607611240 A device driver is a computer program that operates or controls a particular type of device that is attached to a computer. It's a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used. ]]> 2021-06-15 13:57:31 UTC https://padlet.com/1920165/b6vd5eisfoqjjkn8/wish/1607611240
