INFORMATION PROCESSING

1 Scheduling

The Process that involves deciding of the ordering of tasks and allocating of appropriate resources among the different type of possible tasks is called scheduling. Schedules can usually be short term periodical plan such as a daily or weekly schedule, and long – term periodical plan which extends for several months or years.

A schedule consists of a list with a timeline with which possible tasks, events, or activities are intended to take place or a sequence of is intended to take place.

Situation 1

Here is a programme list of two days Zonal level sports meet held on 15th Nov 2018 and 16th Nov 2018 at Bala’s school. To submit the annual report, prepare a schedule and make a table using the column headings given below

2 Flowchart

A Flowchart is a pictorial representation and it gives an idea of instructions to perform a task or calculation. They are widely used in multiple fields to prepare a document, study, plan, improve and communicate often complex process clearly as it is easy to understand a diagram. In the flowchart, each shape has a particular meaning. They are given in the following table.

To understand better, let us see, how we can apply flowchart practically.

2.1 Types of Flowchart

Sequential flowchart

A flowchart describes the operations and in what sequence the problem is to be solved.

Situation 1

Scan QR Code from your textbook to view related digital content. as shown in the pictures below.

First, let us write an step by step process to scan QR code:

Step by Step process

First, let us write an step by step process to scan QR code:

1. Take correct textbook page on which required QR code were situated.

2. Open QR code scanner on your mobile or tab.

3. Scan QR code to view related digital content.

4. View digital content.

Now, let us write a sequence flowchart for this given in figure below.

Example 1 Construct an appropriate flowchart for depositing a sum of money in an ATM using the instruction given below.

Solution

Conditional flowchart

Situation 2

Construct the flowchart to find the sum of given two numbers. (To achieve this, first the two numbers have to be received and kept in two places, under two names. Then the sum of them is to be found and printed. The flow chart for this is given in figure below.)

In the above flow chart, there is a special meaning in writing C = A + B. Here, the value of C indicates the sum of A and B values. For example, if we input A = 325 and B = 486 then the value of C will be printed as 811. Let us learn more from following examples

Example 2 Construct the flow chart to find whether the given number is a positive integer or negative integer or zero and write step by step process.

Solution

In this question we are asked to find the given integer x is a positive number or a negative number or a zero. For that, first we have to assign the value of x and check whether x is greater than 0. If ‘yes’, we will print “x is a Positive number”. If ‘no’ then we will check again if the value of x is less than 0. If ‘yes’, we will print “x is a Negative number”. If ‘no’, then we will print “x = zero”.

Situation 3

Are you familiar with the Internet? If you want to know how to search in the Internet, then you have to find the right search engine, type in your search keywords as accurately as possible, and browse through the results to find the one you want. Let us learn more about this from the following algorithm and flowchart.
