Desktop

The desktop is a fundamental part of the default GUI (graphical user interface) in Windows. It is a space where you can organize applications, folders, and documents, which appear as icons. Your desktop is always in the background, behind any other applications you’re running.

When you power on your computer and log in to Windows, the first thing you see is your desktop background, icons, and the taskbar. From here, you can access the installed programs on your computer from the Start menu, or by double-clicking any application shortcuts you may have on your desktop.

You can access your desktop at any time by pressing Windows key + D to minimize any running applications.

With the release of Windows 8 in 2012, the desktop was no longer the default GUI, replaced by the Start Screen. This change was short-lived, and the desktop returned as the default GUI in Windows 10.

OPERATING SYSTEMS AND UTILITIES

Operating system overview

An operating system (abbreviated OS) is a type of system software that acts as a mast controller for all the activities that take place within a computer system. It is one of the factors that determine your computer compatibilityand platform. The operating system interactswith application software, device drivers, and hardware to manage a computer’s resources. The term resource refers to any component that is required to perform work. For example, the processor is a resource. RAM, storage space, and peripherals are also resources.

Operating system manages different tasks:

— Managememory. OS allocates a specific area of RAM for each program that is open and running. OS is itself a program, so it requires RAM space too. A microprocessor works with data and executes instructions stored in RAM – one of your computer’s most important resources. When you want to run more than one program at a time, the OS has to allocate specific areas of memory for each program. When multiple programs are running, the OS must ensurethat instructions and data from one area of memory do not “leak” into an area allocated to another program. If an OS falls down on the job and fails to protect each program’s memory area, data can get corrupted, programs can “crash”, and your computer displays error messages.

— Manage processor resources. The operating system also controls the microprocessor – just at a slightly higher level. Every cycle of a computer’s microprocessor is a resource for accomplishing tasks. Many activities – called “processes” – compete for the attention of your computer’s microprocessor. OS must ensure that each activity “process” receives its share of microprocessor cycles. A computer can take advantage of performance-enhancing technologies such as multitasking,multithreading,multiprocessing,dual coreormultiple processors.

— Keep track of storage resources. OS stores and retrieves files from your disks and CDs. It remembers the names and locations of all your files and keeps track of empty spaces where new files can be stored.

— Ensure that input and output proceed in an orderly manner. OS communicates with device driver software so that data can travel smoothlybetween the computer and these peripheral resources. OS uses ‘buffers’ to collect and hold data while the computer is busy with other tasks.

— Establish basic elements of the user interface. A user interface can be definedas the combination of hardware and software that helps people and computers communicate with each other. Your computer’s user interface includes a display device, mouse, and keyboard that allow you to view and manipulate your computer environment. It also includes software elements, such as menus and toolbar buttons. A graphical user interface (GUI)features menus and icons that you can manipulate with the click of a mouse. A command-line interface requires you to memorize and type commands.

For nearly all PCs, servers, workstations, mainframes, and supercomputers, the operating system program is quite large, so most of it is stored on a hard disk. The operating system’s small bootstrap program is stored in ROM and supplies the instructions needed to load the operating system’s core into memory when the system boots. This core part of OS called the kernelprovides the most essential operating system services, such as memory management and file access. The kernel always stays in RAM all the time your computer is on. Other parts of OS, such as customization utilities, are loaded into RAM as they are needed.

Many operating systems provide helpful tools, called operating system utilities, that you can use to control and customize your computer equipment and work environment. They are typically accessed by using a GUI, such as the familiar Windows desktop. The most popular are: launch programs, manage files, get help, customize the user interface, and configure equipment.

One operating system might be better suited to some computing tasks than others. To provide clues to their strengths and weaknesses, operating systems are informally categorized using one or more of the following terms:

A single-user operating system expects to deal with one set of input devices – those that can be controlled by one user only.

A multiuser operating systemallows a single computer to deal with simultaneousinput, output, and processing requests from many users. One of its most difficult responsibilities is to schedule all the processing requests that a centralized computer must perform.

A network operating system provides communications and routing services that allow computers to share data, programs, and peripheral devices. The main difference between network OS and multiuser OS is that multiuser operating systems schedule requests for processing on a centralized computer, whereas a network operating system simply routes data and programs to each user’s local computer, where the actual processing takes place.

A desktop operating system is one that is designed for a personal computer. Typically, these operating systems are designed to accommodate a single user, but might also provide network capability.

Windows is the best-selling operating system. The number and variety of programs that run on Windows are unmatched by any other operating system, a fact that contributes to its dominant position as the most widely used desktop operating system.

Utility software is a type of system software that is designed to perform a specialized task, such as system maintenance or security. Utility software that does not come packaged with an operating system is often referred to as a third-party utility. In past years, antivirus software was a popular category of third-party utilities. With the recent influx of nuisance ads, intrusion attempts, and spam, utilities such as ad blockers, personal firewalls, and spam filters have also become best sellers. Filtering software is used by parents to block their children from objectionable Websites. Another popular category of utility software is system utilities. These utilities track down and fix disk errors, repair corrupted files, and give your PC a performance – enhancing tune-up.

A final group of utilities worth mentioning is designed for backing upand cleaning up hard disks, and shreddingfiles so they can’t be recovered. They can help you recover files deleted by mistake.

Comprehension check. Indicate the paragraph where the following ideas are found in the text.

1. Operating system’s main purpose is to control what happens behind the scene.

2. Your PC can sometimes recover from memory leak problems if you use the Ctl+Alt+Del key sequence to close the corrupted program.

3. The operating system must ensure that the microprocessor does not “spin its wheels” waiting for input while it could be working on some other processing projects.

4. Windows is installed on more than 80 % of the world’s personal computers.

5. The term “buffer” is a technical jargon for a region of memory that holds data waiting to be transferred from one device to another.

6. Many operating systems provide helpful tools, called operating system utilities, that you can use to control and customize your computer equipment and work environment.

Lesson 8: Understanding Operating Systems

What is an operating system?

An operating system is the most important software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer’s language. Without an operating system, a computer is useless.

Watch the video below to learn more about operating systems.

Looking for the old version of this video? You can still view it here.

The operating system’s job

Your computer’s operating system (OS) manages all of the software and hardware on the computer. Most of the time, there are several different computer programs running at the same time, and they all need to access your computer’s central processing unit (CPU), memory, and storage. The operating system coordinates all of this to make sure each program gets what it needs.

Types of operating systems

Operating systems usually come pre-loaded on any computer you buy. Most people use the operating system that comes with their computer, but it’s possible to upgrade or even change operating systems. The three most common operating systems for personal computers are Microsoft Windows, macOS, and Linux.

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, and everything is clearly displayed on the screen using a combination of graphics and text.

Each operating system’s GUI has a different look and feel, so if you switch to a different operating system it may seem unfamiliar at first. However, modern operating systems are designed to be easy to use, and most of the basic principles are the same.

Microsoft Windows

Microsoft created the Windows operating system in the mid-1980s. There have been many different versions of Windows, but the most recent ones are Windows 10 (released in 2015), Windows 8 (2012), Windows 7 (2009), and Windows Vista (2007). Windows comes pre-loaded on most new PCs, which helps to make it the most popular operating system in the world.

Check out our tutorials on Windows Basics and specific Windows versions for more information.

macOS

macOS (previously called OS X) is a line of operating systems created by Apple. It comes preloaded on all Macintosh computers, or Macs. Some of the specific versions include Mojave (released in 2018), High Sierra (2017), and Sierra (2016).

According to StatCounter Global Stats, macOS users account for less than 10% of global operating systems—much lower than the percentage of Windows users (more than 80%). One reason for this is that Apple computers tend to be more expensive. However, many people do prefer the look and feel of macOS over Windows.

Check out our macOS Basics tutorial for more information.

Linux

Linux (pronounced LINN-ux) is a family of open-source operating systems, which means they can be modified and distributed by anyone around the world. This is different from proprietary software like Windows, which can only be modified by the company that owns it. The advantages of Linux are that it is free, and there are many different distributions—or versions—you can choose from.

According to StatCounter Global Stats, Linux users account for less than 2% of global operating systems. However, most servers run Linux because it’s relatively easy to customize.

To learn more about different distributions of Linux, visit the Ubuntu, Linux Mint, and Fedora websites, or refer to our Linux Resources. For a more comprehensive list, you can visit MakeUseOf’s list of The Best Linux Distributions.

Operating systems for mobile devices

Operating systems for mobile devices generally aren’t as fully featured as those made for desktop and laptop computers, and they aren’t able to run all of the same software. However, you can still do a lot of things with them, like watch movies, browse the Web, manage your calendar, and play games.
