  1. Lesson 2 Cont. Computer Applications Security & Utility, PIM and Integrated & Suites

  2. Security Programs • Help keep bad guys from messing with your computer and its data. • Purpose: • To avoid or repair damage from malware (a virus, trojan, worm or other intrusive software). • Major Advantage: • Protection is easier than recovering from a malware disaster. • Major Disadvantages: • Must be configured correctly to work effectively. • Must be updated regularly with new virus definitions.

  3. Security Programs Types of security programs: • Anti-virus: • Continuously watches for incoming attacks. Scans regularly for hidden malware. Repairs many kinds of damage. • Firewall: • Controls who gets into your computer from the Internet. • Anti-spam: • Examines incoming email and sends known or suspected bad messages to a special folder, Spam or Junk.

  4. Security Programs Examples of security programs: • Norton Security Suite • Microsoft Defender • AviraAntiVirus • Windows Firewall • Norton 360 • Trend Micro Internet Security Plus • Zone Alarm

  5. Utility Programs Purpose: • To customize the way the computer behaves, making it more efficient or easier or safer to use. Major Advantages: • Better features or better user interface than what comes with the operating system. • Special features for keeping your computer running well. • Configuring your computer to suit the way you work. Major Disadvantage: • Many are very technical and require some expertise to use.

  6. Security Programs • Parental control programs block access (especially for children) to web sites that are not suitable or are more likely to result in malware attacks. • Encryption programs encode your data so that to read it the user must have the right key code.

  7. Security Programs • Password management software remembers all of your logon and password information so that you only have to remember how to get into the password software. • Back-up software can automatically save a copy of your data or the whole computer's contents to DVDs, tape, or to a data site online.

  8. Security Programs • Disk defragmenting software rearranges files so that all parts of the file are next to each other. Defragmenting makes it easier for the computer to find and display the file.

  9. PIM – Personal Information Management A PIM normally includes : • address book • calendar to schedule activities and appointments • to-do list where you list chores, calls to make, or various things to do.

  10. PIM Programs Some popular programs are: • Microsoft Office Outlook • Lotus Organizer • Windows Calendar and Windows Contact List • Google Calendar and Google Notebook • Palm Desktop • Novell Groupwise

  11. PIM Advantages • Major Advantages: • Quick access to schedule data and address book. • Can often be merged into documents directly.

  12. Contact Manager • A contact manager automatically links a name in the address book to names in the calendar. • An advanced PIM may be called a Contact Manager. Such a program is optimized to make it easy to track who you have talked to or met with and what you did or said.

  13. Integrated Software • Integrated software combines the functions of several programs into one interface. • Such a program is usually designed for the beginning or casual user. • Microsoft Works is an example of integrated software.

  14. Suites • A popular suite of office software is MS Office. These include several programs, such as: • word processing • spreadsheet • presentations • e-mail client • address book • database

  15. Suites • An example of a graphics suite is Corel Draw Suite, which includes programs for: • vector illustration • layout • bitmap creation • image-editing • painting • animation software

  16. Suites • An example of a publishing suite is Adobe Publishing Collections, which includes: • Adobe PageMaker - desktop publishing • Adobe Photoshop - bitmap graphics • Adobe Illustrator - vector graphics • Adobe Acrobat - converts documents to Portable Document Format for sharing

  17. Suites Purpose: • Linking different applications together for better work (integrated software). Simplifying things for new users. Major Advantage: • Costs less than a set of similar stand alone applications bought separately. Major Disadvantage: • (integrated software) Lacks many features of the stand-alone versions of the same software. • (suites) You may not need all the parts or the advanced features in the collection.
