Computing Fundamentals Unit 4- Computer Software
Objectives Identify how hardware & software interact Explain how a software program works Describe the difference between application and system software Describe the software distribution process
Hardware vs. Software What is Hardware? What is Software? Hardware is physical You can touch it What is Software? Instructions to perform a task Programming code Program is another name Program gets loaded into RAM Both work together & interact Look! This is a notes page. Here, I can write notes to myself & print it out so when I give a speech I can remember to say what I wrote here.
Hardware & Software Working Together
How a Program Works Computer processes data by applying rules Algorithm Steps to perform a task What are the steps to doing laundry?
Developing Software Develop algorithm into flowchart Programmer writes code Beta testing Evaluated by actual users Does it meet requirements? Report bugs Debugging Fixing the problems
2 Types of Software Applications Systems Helps you do a task OS & utility programs Allows you to interact w/ hardware Manages computer resources
Application Software Runs on top of system software & performs a specific function Productivity Software Word processing, spreadsheet, database, presentation, desktop publishing Entertainment Software Playing music, videos, viewing photos Media Editing Software Creating & modifying graphics, animations, videos These are often packaged in suites, which include multiple programs in one (cheaper than buying separate programs). Microsoft Office, Google Docs, Open Office, Apple iWorks Adobe Creative Suite, CorelDRAW
Review What are the two types of software categories? Application & System Describe hardware. Physical device What’s another name for software? Programs A new game has been developed. Who made it? Programmer Who tests it? Beta tester/user What process fixes all the problems? Debugging
Productivity: Word Processing Create, edit, format, print documents Letters, reports, memos, flyers Collaboration Share via email, cloud, or blog Edit in real time Word, Word Perfect, Google Doc, Apple Pages Note the difference between editing & formatting. Formatting- appearance of elements on the page (stylized text, colors, styles)
Productivity: Desktop Publishing Similar to word processing Text & graphics Used to create & print high quality brochures, magazines, newspapers, etc. Adobe InDesign, QuarkXPress, Publisher
Productivity: Spreadsheet Evaluate & calculate data Worksheet, workbook, cells, functions, formulas, charts Excel, Lotus 1-2-3, Quattro Pro Note the difference between functions & formulas. FUNCTION- =SUM or =NOW is an equal sign with a word FORMULA- =1+2+3 is an equal sign with no words formulas can be within functions Sample uses: budgets, balancing checkbooks, forecasting loan payments, maintaining grade books
Productivity: Presentations Organize & present information Slide show Present to audience PowerPoint, iWork Keynote, Prezi, Corel Presentations Can apply layouts, themes, transitions, animations
Productivity: Presentations Notes Page Slide
Productivity: Database Management Collection of info organized for quick retrieval Create, maintain, provide access to data Access What business would use it & what info? Keywords: Table (all info stored in it) Field (a column of info, such as Name of Movie) Record (a row of info; related fields) Primary Key (unique ID) Query (request for specific info) About the data database- customer info, hospital records, inventory DVDs, collect data
Productivity: Database Management Table- columns & rows of data; record- row of info; field- column specific info; query- asks a ?; report
Review- Q
Media Editing: Graphics Pictures/Photo editing Photoshop, Paint, CAD Formats Tiff, jpg, gif, bmp Each has different qualities Tiff BEST but not browser compatible
Paint Select Zoom Text Draw Shapes Erase
Project Recreate a project in Paint Become familiar with functions
Other Software Multimedia- Video, Music, Animation Email Browsers Mpg, mp3, wav Email Windows Mail/Outlook Eudora (one of the 1st) Browsers IE, Chrome, Opera, Firefox Name some audio editing software: Adobe Audition, Garage Band, Audacity Video editing: Windows Movie Maker, Adobe Premiere, iMovie
Review What was one of the 1st email programs? Eudora A record can be found in which program? Database Name some picture formats. Jpg, gif, bmp, tiff Name some multimedia formats. Mpg, mp3, wav Which program can calculate data? Spreadsheet
Review What is the highlighted area called? Record
Systems Software Manage resources, files OS Utilities Communicates between user & hardware GUI Utilities Antivirus Backup File management (more on next slide)
Utilities Backup Antivirus Saves data on another drive Protects PC from virus damage Subscription Scheduled Scans Antivirus terms- Malware (Malicious software which includes viruses, worms, Trojans, spyware) DEFINE BASICS OF EACH!
Defrag, Cleanup, Compress Defragmentation (example) Files are all over the place Defrag places parts of a file closer together Disk Cleanup Frees up disk space Deletes Recycle Bin & temp files File Compression Makes one large file smaller Disk Compression Squeezes files on HD
Review- Q
Getting Software Licensing Web applications (SaaS) Single-user (one PC) Site/Network/Volume license (installed on all PCs in business) Site license is cheaper than buying all single-user license Web applications (SaaS) Login online Google Docs Upgrade existing software to new version New features & better compatibility Like a new version of Office Single-user license cost $200. Site reduces the per PC cost to $100. Find the version of office (About)
Updating Software Updates/Patches/ Service Packs Fix errors Change minor features Get from manufacturer’s web site Version 1.2.1 Windows 7 SP2
Freeware vs. Shareware Freeware Shareware Free software to download Owner has copyright For personal use No rights for you to distribute Shareware Trial period Pay after that
Review What is the purpose of defrag? Moves parts of a file closer for faster access Which software is a trial version? Shareware Where is the best place to get a download that will fix a security hole in Windows? Microsoft (manufacturer of program) Which utility option will squeeze files on a HD closer together to create more room? Disk compression
Review To use software legally, you must have what? License Which software is free for personal use only? Freeware What is a patch? An update that fixes an error in a program Which utility option will delete the Recycle Bin & temp files? Disk cleanup What protects a PC from viruses? Anti-virus software
