Discuss the major software issues that confront modern organizations. 2. Describe the general functions of the operating system. 3. Identify the major types of application software. 3 FIGURE TG 2.1 TYPES OF SOFTWARE 4  INTRODUCTION TO SOFTWARE Software: a set of computer programs that enable the hardware to process data Computer program: the sequence of instructions for the computer, which comprise software Documentation: written description of the functions of a software program Systems software: a set of instructions that serves primarily as an intermediary between computer hardware and application programs Application software: a set of computer instructions that provide more specific functionality to a user 5  TG 2.1 SOFTWARE ISSUES Software Defects Software licencing: see topics from The Software Alliance: ww2.bsa.org/country.aspx?sc_lang=en-CA Open Systems Open-source Software 6  OPEN-SOURCE SOFTWARE Advantages Disadvantages Cost of maintenance High quality Ease of use Reliability Training costs Low Cost Compatibility issues Flexibility 7  TG 2.2 SYSTEMS SOFTWARE Operating system: supervises the overall operation of the computer by monitoring the computer’s status, scheduling operations, and managing input and output processes. Functions performed by systems software: Control and support information processing activities Control and support peripherals (e.g. printers, keyboard, mouse) Enables self-regulatory functions of the computer Provides commonly used sets of instructions for all applications Supports application software by directing the computer’s basic functions 8  TYPES OF USER INTERFACES Graphical User Interface (GUI): allows users to exercise direct control of the hardware through manipulation of visible objects (such as icons) and actions that replace complex commands. Natural user interfaces (NUIs): social, haptic [tactile], and touch-enabled gesture-control interfaces Social Interface: guides the user through computer applications by using cartoonlike characters, graphics, animation, and voice commands. Motion control gaming consoles Touch-enabled gesture-controlled interfaces 9  TG 2.3 APPLICATION SOFTWARE Major Types of Personal Application Software Spreadsheets Word Processing Desktop Publishing Data Management Presentation Graphics Personal Information Management Personal Finance Web Authoring Communications 10  TECHNOLOGY GUIDE CLOSING 1. Major software issues that confront modern organizations: software licensing and computer program code often contains errors. 2. Advantages of open-source software include high quality, reliability, flexibility and low cost. 3. Disadvantages of open-source software include the cost of maintenance support contracts, ease of use, training users, and compatibility issues. 4. There are two main categories of software: systems software and application software. 11  2017 Copyright © 2017 John Wiley & Sons Canada, Ltd. All rights reserved.
