Computer Essentials – Session 1 – Step-By-Step Guide
Computer Essentials – Session 1 – Step-by-Step Guide Note: Completing the Mouse Tutorial and Mousercise exercise which are available on the Class Resources webpage constitutes the first part of this lesson. ABOUT PROGRAMS AND OPERATING SYSTEMS Any time a task is performed on a computer, it is done through a program. For the user, the program is the application – the tool – for accomplishing a task. For the computer, it is a set of instructions on knowing how to perform this task. Examples of programs include Internet Explorer and Microsoft Word. The most important program overall is the operating system, which manages all of the computer’s resources and decides how to treat input from the user. There are several different operating systems in circulation, such as Mac O/S and Linux. However, far and away, the most commonly-used operating system is Microsoft Windows. (Note that Microsoft is just the name of the company that makes Windows, and that there are several versions of Windows. In 2012 all the computers in the lab were updated to the version of Windows called Windows 7. If you have some experience with the older versions of Windows you will notice that things look a bit different on a computer running Windows 7. THE WINDOWS 7 ENVIRONMENT The Desktop The first thing you see when you log on to the computer is the DESKTOP. The Desktop is the display area you see when Windows opens. The following items are the most common items that can be found on the desktop: Mouse pointer Icons Shortcuts to Storage drives Notification Start Button Taskbar tray Show Desktop/Peek button Andrea Philo September 2012 Page 1 of 13 Montgomery County-Norristown Public Library Computer Essentials – Session 1 – Step-by-Step Guide Parts of the Windows 7 Desktop Icon: A picture representing a program or file or places to store files. -
UKUI: a Lightweight Desktop Environment Based on Pluggable
2016 International Conference on Artificial Intelligence and Computer Science (AICS 2016) ISBN: 978-1-60595-411-0 UKUI: A Lightweight Desktop Environment Based on Pluggable Framework for Linux Distribution Jie YU1, Lu SI1,*, Jun MA1, Lei LUO1, Xiao-dong LIU1, Ya-ting KUANG2, Huan PENG2, Rui LI1, Jin-zhu KONG2 and Qing-bo WU1 1College of Computer, National University of Defense Technology, Changsha, China 2Tianjin KYLIN Information Technology Co., Ltd, Tianjin, China *[email protected] *Corresponding author Keywords: Desktop environment, Ubuntu, User interface. Abstract. Ubuntu is an operating system with Linux kernel based on Debian and distributed as free and open-source software. It uses Unity as its default desktop environment, which results in more difficulties of usage for Microsoft Windows users. In this paper, we present a lightweight desktop environment named UKUI based on UbuntuKylin, the official Chinese version of Ubuntu, for Linux distribution. It is designed as a pluggable framework and provides better user experience during human-computer interaction. In order to evaluate the performance of UKUI, a set of testing bench suits were performed on a personal computer. Overall, the results showed that UKUI has better performance compared with Unity. Introduction Linux is a freely available operating system (OS) originated by Linux Torvalds and further developed by thousands of others. Typically, Linux is packaged in a form known as a Linux distribution for both desktop and server use. Some of the most popular mainstream Linux distributions are Red Hat [1], Ubuntu [2], Arch [3], openSUSY [4], Gentoo [5], etc. There are several desktop environments available for nowadays modern Linux distributions, such as XFCE [6], GNOME [7], KDE [8] and LXDE [9]. -
The GNOME Desktop Environment
The GNOME desktop environment Miguel de Icaza ([email protected]) Instituto de Ciencias Nucleares, UNAM Elliot Lee ([email protected]) Federico Mena ([email protected]) Instituto de Ciencias Nucleares, UNAM Tom Tromey ([email protected]) April 27, 1998 Abstract We present an overview of the free GNU Network Object Model Environment (GNOME). GNOME is a suite of X11 GUI applications that provides joy to users and hackers alike. It has been designed for extensibility and automation by using CORBA and scripting languages throughout the code. GNOME is licensed under the terms of the GNU GPL and the GNU LGPL and has been developed on the Internet by a loosely-coupled team of programmers. 1 Motivation Free operating systems1 are excellent at providing server-class services, and so are often the ideal choice for a server machine. However, the lack of a consistent user interface and of consumer-targeted applications has prevented free operating systems from reaching the vast majority of users — the desktop users. As such, the benefits of free software have only been enjoyed by the technically savvy computer user community. Most users are still locked into proprietary solutions for their desktop environments. By using GNOME, free operating systems will have a complete, user-friendly desktop which will provide users with powerful and easy-to-use graphical applications. Many people have suggested that the cause for the lack of free user-oriented appli- cations is that these do not provide enough excitement to hackers, as opposed to system- level programming. Since most of the GNOME code had to be written by hackers, we kept them happy: the magic recipe here is to design GNOME around an adrenaline response by trying to use exciting models and ideas in the applications. -

Word is a powerful word processor with sophisticated editing and formatting as well as graphic- enhancement capabilities. Word is a good program for novice users since it is relatively easy to learn and can be integrated with language learning. Word processing has become popular due to its wide range of personal, business, and other applications. ESL learners, like others, need word processing for job search, employment, and personal purposes. Word-processing skills have become the backbone of computer literacy skills. Features PARTS OF THE SCREEN The Word screen can be overwhelming for novice learners. The numerous bars on the screen such as toolbars, scroll bars, and status bar confuse learners who are using Word for the first time. It is important that learners become familiar with parts of the screen and understand the function of each toolbar but we recommend that the Standard and Formatting toolbars as well as the Status bar be hidden for LINC One level.

Lumina-DE: Redefining the Desktop Environment for Modern Hardware
Lumina-DE: Redefining the Desktop Environment for Modern Hardware Author: Ken Moore [email protected] PC-BSD/iXsystems Lumina Desktop source repository: https://github.com/pcbsd/lumina Date: Nov 2014 Abstract: As computers continue to advance into every aspect of our daily lives through the pervasiveness of cell phones and tablets, the traditional “desktop computer” is gradually being shifted to a smaller subset of the total systems in use. This presents a problem for open source operating systems, as the available open source graphical environments are increasingly designed for systems with powerful hardware or traditional mouse/keyboard inputs – resulting in a much lower percentage of devices that are physically capable of utilitizing the OS. The open-source Lumina desktop environment is designed to solve these problems by meeting its goals of being a highly flexible and scalable interface that runs with relatively little hardware requirements. The project also provides a simple framework for integrating OS-specific functionality directly into the interface for ease-of-use without causing conflict with the underlying system or affecting portability. This paper will take a top-level view of the Lumina desktop project, breaking it down to its components, explaining the framework and methodology, and listing the work that is still yet to be completed to achieve its goals. Please note: for all intents and purposes, there is no distinction between laptops and box-based desktop computers when it comes to the capabilities and distinctions of a graphical interface, so for the purposes of this paper they will both be considered “desktop” systems. The Problem: Smartphones, tablets, laptops and desktop computers all utilitize graphical interfaces to provide the user access to the capabilities of the device, but laptops and desktop computers are the only ones with fully open source desktop environments available. -
Remove ANY TOOLBAR from Internet Explorer, Firefox and Chrome
Remove ANY TOOLBAR from Internet Explorer, Firefox and Chrome Browser toolbars have been around for years, however, in the last couple of months they became a huge mess. Unfortunately, lots of free software comes with more or less unwanted add-ons or browser toolbars. These are quite annoying because they may: Change your homepage and your search engine without your permission or awareness Track your browsing activities and searches Display annoying ads and manipulate search results Take up a lot of (vertical) space inside the browser Slow down your browser and degrade your browsing experience Fight against each other and make normal add-on handling difficult or impossible Become difficult or even impossible for the average user to fully uninstall Toolbars are not technically not a virus, but they do exhibit plenty of malicious traits, such as rootkit capabilities to hook deep into the operating system, browser hijacking, and in general just interfering with the user experience. The industry generally refers to it as a “PUP,” or potentially unwanted program. Generally speaking, toolbars are ad-supported (users may see additional banner, search, pop-up, pop-under, interstitial and in-text link advertisements) cross web browser plugin for Internet Explorer, Firefox and Chrome, and distributed through various monetization platforms during installation. Very often users have no idea where did it come from, so it’s not surprising at all that most of them assume that the installed toolbar is a virus. For example, when you install iLivid Media Player, you will also agree to change your browser homepage to search.conduit.com, set your default search engine to Conduit Search, and install the AVG Search-Results Toolbar. -
