1. The document discusses installing Windows Logic and Techniques programming using attended installation. It covers input, process, output cycles, flowcharts, and drawing simple flowcharts.
2. Flowcharts use symbols to represent activities like input, processing, output, decisions, and subroutines. Examples show flowcharts for making tea, manipulating numbers, and calculating sales.
3. Exercises provide practice drawing flowcharts for student admission, adding numbers, summing entered numbers, and multiplying a number.

Rationale
The Programming Logic and Techniques (PLT) module is
positioned as the entry point into this curriculum. Since this
curriculum is designed to cater to aspiring software
professionals, a strong foundation in programming
approaches and application of logic was found essential
and was recommended by the industry.
In the OOPs using C# module the students will be required
to write programs involving the use of programming
constructs. The PLT module, apart from teaching problem
solving technique like flowcharting, will also prepare the
students for the OOPs using C# module by developing the
student’s ability to study, solve and represent the logic of
the problems.

Input-Process-Output Cycle
The cycle of activities performed by a computer is referred
to as the Input-Process-Output cycle or the I-P-O cycle.
A computer consists of several components.
Each component participates in either one of the input,
process, or output phases.

Programs
A computer is designed to accept input, process it, and
generate output.
A set of instructions to perform a task is called a program.
A number of programs together form an application.
