thaks juste all material are very helpfull

So basically what I have understand about this assignment is:

We need to draw two diagrams level 0 and level 1.

(For level 0, handouts lecture # 5 page # 61)

(For level 1, handouts lecture # 6 page # 63)

In level 0 we will draw a diagram which will describe the working of the system. We have to draw/write about the basics of the system but we don't have to go in details.

In level 1 (Detailed Data Flow Diagram) we will go in details of the whole system. Have to draw/explain the depths of the system.

Can someone please tell me If I am am wrong or correct?

Where is the level 1 diagram???


The level 1 diagram is not available in handouts.

Dear Student,

You have to draw DFD in Microsoft Visio which is mentioned in assignment file as well. Copy /Paste diagram in MS Word and send .doc file i.e, word file.

  • He/she will get authentication from website

is sentence ka kya meaning hai?

matlb k ajazt mil jati agr sign k lia krta ttry phr responce main ijzt milti k ho jao passwerd thek hai email b

For suppose you are logging into you Gmail account, Google will verify/confirm whether your given id and pass is matching with the id and pass saved in it's server or not.

This is called authentication from website.
