Trends
 There is a shift from a hardware view of
computing to software & services
"Ten years out, in terms of actual
hardware costs you can almost think of
hardware as being free -- I'm not
saying it will be absolutely free -- but in
terms of the power of the servers, the
power of the network will not be a
limiting factor," Gates said, referring to
networked computers and advances in
the speed of the Internet.

Software from Conception
to Installation and Beyond
Succeeding with Technology
Recall…2 Types of Software
 System Software
controls the
hardware and runs
the computer
system.
Succeeding with Technology
 Application
Software provides
services for people.
How Software Works
 Software consists of a
number of files at least
one of which is
“executable”.
 Executable File: stores
computer instructions in
binary machine language.

Programming Languages
 A programming language is the primary tool of
computer programmers, providing English-like
commands for writing software that is translated into
the detailed step-by-step instructions executed by the
processor.
A Programming Statement in C++
cout << "\nPlease Enter The Password:";
Syntax: a set of rules that describe how
programming statements and commands
should be written.

Programming Process
Source Code
void main()
{
Password.cpp
char password[200] = "opensaysme";
char input[200];
while(strcmp(password, input)) {
clrscr();
cout << "\nPlease Enter The Password:";
cin >> input;
Compiler
}
}
cout << "\nWelcome, Oh Great One!\n";
exit(1);

The Program
Commercial software
You only get the "Executable Code".
It impossible to translate executable
code back to the original "Source
Code".

Turing Test
“A human judge engages in a
natural language conversation
with two other parties, one
human, the other a machine; if
the judge cannot reliably tell
which is which, then the
machine is said to pass the
