2 What is Computer Software? EQ: What are the software components of a computer? T-IDT-4 4.3 Describe and explore current and emerging software, including operating systems and application software. a. Explain the function and purpose of software tools. 4.4 Compare and contrast various hardware and software options for personal and business use.

3 Hardware vs Software Got to have both to get the job done!

4 How does Software work? Algorithms have to be written Algorithm turned into computer language Another specialized program turned this language into something the computer understands Software development – multi-step process First programmer – Grace Hooper – created FLOW MATIC (later known as – COBOL)

5 Types of Software Applications Software / Productivity Microsoft Office Systems Software Operating systems Utilities Entertainment / Games

6 Applications Software

7 Operating Systems Interface between user and the computer Many brands Windows – designed for processor Intel Macintosh computers use processor made by Motorola – OS Linux / Unix

8 Utility Software Helps perform housekeeping chores Tasks include: Antivirus programs Copy file from hard drive to another location Convert graphics file so it can be used by another program Backup copy of hard drive

9 User Interfaces Determines how user friendly the computer is Part we interact with when using the computer Command-line interface such as DOS Graphical interfaces such as Windows

10 Command Line Early computers used only this Have to memorize codes Not very user friendly Not colorful – usually written in black and white No pictures

11 Graphical User interfaces Came about with menus Graphical user interface (GUI) Came about with Apple’s development of Macintosh Finder Pictures (icons) represent software Colorful Contributed to the explosion of computer use.

12 Games / Entertainment Purely for leisure Billion dollar industry Contributed hugely to jobs in software programming Extremely popular with the younger generation of computer users

13 Assignment 1 Three types of software for our lesson are: ________________________ Systems Software ________________________ Windows is an example of this type software ____________ ___________. Graphical design programs like Pinnacle 17 or Adobe premier would be considered a _______________ software application. ______________ is a precise set of rules created to solve a problem. Software applications are written in __________ __________ after the algorithm is designed. Dos was and example of a __________ _____________ interface. GUI stands for _____________ _______________ _________________ An operating system is the interface between the __________ and the _________

14 Assignment 2 For the next scenarios, use one the three choices Application / Utility / Entertainment Software to copy files from one location to another: __________________ Microsoft Powerpoint : __________________ Symantec System Backup:____________________ World of Warfare game: _____________________ Pinnacle Studio 17 – video editing software: _________________ Microsoft Excel _________________ Disk Optimizer software: ________________________ Youtube video player ______________________

15 Project Research the three operating systems: Mac OS v.? Windows XP or 7 Unix List 2 advantages and 2 disadvantages of each Which one do you think would be the best for someone to use in a home business and why? List each OS and research what the best market or use this operating system seems to be associated with. For example, on Windows, seems to be more associated with business productivity.
