(Microsoft, Adobe)

Open Source - software whose source code is free. Anyone can
change, copy, or distribute it. (Linux, Apache)
two basic types of computer software

Operating System Software - Directs all the activities and sets all the
rules for how the hardware and software will work together.

Application Software - Programs that work with operating system
software to help the computer to do specific types of work.
System Software

3 common operating system software for desktops and laptops

introduced before Windows

commercial software installed only
on Apple computers

not as many application software
as Windows

not as many viruses as Windows
Linux

open source software installed
on desktops

not as widely used

popular with Techies

can run on older machines

very few application software
available

hardly any virus attacks
Tablet and Smartphone Operating

terminology associated with
computer software
ICT 2 Activity - Creating and
Moving Files

Follow along with the “Creating
and Moving Files” Handout to
learn how to create folders and
move files
Application Software

File Management

managing files and folders
correctly can prevent wasted
time, frustration and errors.

proper file management begins
with using file naming conventions
and good organization.
guidelines for naming files and
folders:

Use short, simple file and folder names

Use file and folder names that describe the content accurately.

Use underscores instead of spaces in file names. For example:
descriptive_essay

Use all lowercase letters in file names.

Avoid using characters such as: ! # $ % @ ^ ` ~ + ; = in file and folder
names. Some systems do not allow you to use characters in file and
folder names, and will not accept them.
File Extensions

A file extension is the suffix at the end of a filename that indicates
what type of file it is.
