Flow chart


A flowchart is a graphical representation of Algorithm. It was originated from computer science as a tool for representing algorithms and programming logic but had extended to use in all other kinds of processes. Nowadays, flowcharts play an extremely important role in displaying information and assisting reasoning. They help us visualize complex processes, or make explicit the structure of problems and tasks. A flowchart can also be used to define a process or project to be implemented.

 

Flowchart Symbols

Different flowchart shapes have different conventional meanings. The meanings of some of the more common shapes are as follows:

Terminator

The terminator symbol represents the starting or ending point of the system.

Process
A box indicates some particular operation.

Decision

A diamond represents a decision or branching point. Lines coming out from the diamond indicates different possible situations, leading to different sub-processes.

Data

It represents information entering or leaving the system. An input might be an order from a customer. Output can be a product to be delivered.


Loop

This symbol represents a looping point. Lines coming out from the Symbol indicates different possible situations.

Characteristics of computers

    Characteristics:        All computers have similar characteristics, which tells how computers are efficient to perform task. Computers have some Limitations also. Speed:     Computer can work very fast. It takes only few seconds for calculations on very large amount of data. Computer can perform millions (1,000,000) of instructions per second.      We measure the speed of computer in terms of microsecond (10-6 part of a second) or nanosecond (10 to the power -9 part of a second).   Accuracy:        The degree of accuracy of computer is very high and every calculation is performed with the same accuracy.  The errors in computer are due to human and inaccurate data.       The calculation done by computer are 100% error free, If we provide accurate input. Diligence:        A computer is free from tiredness, lack of concentration...

DS LAB FOR II YEAR

1.SINGLE LINKED LIST Procedure for creation of single linked list: STEP-1 : Declaring a variable named as “item”.Ie the element what we place in the linkedlist of the new node.         STEP-2 : Read the value   in “item”. Set first=last=null and next=null. STEP-3: Create a new node named as temp and assign the variable item to data part andassign Address of the node temp to null.       temp.data=item;       temp.next=null; STEP-4: Check   the address part of the first node Check if first=null Then assign first=last=temp Other wise Then assign the new node tolast.next=temp          last=temp STEP-6 : Repeat STEP-3 until you read required nodes. Procedure for display the linked list: STEP-1 : Check whether the list having nodes or not i.e Check if first=null        ...

LEVELS AND CURVES

LEVELS:                 Levels are used to set the shadows, mid tone etc.  O pen an image on Photoshop window. Select image menu on menu bar than adjustments than levels.

The black triangle indicates shadows and gray triangle indicates mid tone and white triangle indicates highlights. In the channel menu different options are provided in drop down list. Make sure select on preview, which gives current adjustments on your picture. CURVES: Curves are to  similar to levels, it gives more power to control shadows highlights and mid tones. One of the simplest adjustment we can make with curves is increasing the contrast. Go to image menu and than adjustments,than curves. Dialogue box will appear on screen with straight diagonal line.      ...
