2. Traditional view Desktop application types Console application
usually performs a restricted function or set of functions at a low level (e.g. OS utilities like MKDIR or TYPE)
Windows/GUI application
Generic applications (e.g. word processor, graphic design) usually have creative output
Specialised applications (e.g. Sat Nav, accounts) usually perform a set of functions or process data

3. Web applications
Web interface used to interact with program on web server.
Program produces web page output.
Program accepts input from web page based forms.
Program may be interpreted or compiled.
Perl, PHP, ASP are interpreted.
Java, ASP.NET are compiled to intermediate code.
ASP.NET may be compiled to native code under some circumstances
We’ll look at this in more detail in weeks 2 & 3

4. Exploding software
An application program, or web application is not a free standing piece of code.
It isn’t the only software in the computer system.
It may need other computers to perform some of the functions
It requires support from the other software components within the computer system.
It may have been created from a collection of cooperating modules.
What are these other pieces?
