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)

Utility Software
Helps perform housekeeping choresTasks include:
Antivirus programsCopy file from hard drive to another locationConvert graphics file so it can be used by
another programBackup copy of hard drive

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

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.
