NIELIT Syllabus Booklet ‘O’ Level (IT)-Revision V.



3. Module: M3-R5: Programming and Problem Solving though Python Language.

(i) Introduction to Programming:-

The basic Model of computation, algorithms, flowcharts, Programming Languages, compilation, testing & Debugging and documentation.

(ii) Algorithms and Flowcharts to Solve Problems :-

Flow Chart Symbols, Basic algorithms/flowcharts for sequential processing, decision based processing and iterative processing. Some examples like: Exchanging values of two variables, summation of a set of numbers, Decimal Base to Binary Base conversion, Reversing digits of an integer, GCD (Greatest Common Division) of two numbers, Test whether a number is prime, factorial computation, Fibonacci sequence, Evaluate ‘sin x’ as sum of a series, Reverse order of elements of an array, Find largest number in an array, Print elements of upper triangular matrix, etc.

(iii) Introduction to Python:-

Python Introduction, Technical Strength of Python, Introduction to Python Interpreter and program execution, Using Comments, Literals, Constants, Python’s Built-in Data types, Numbers (Integers, Floats, Complex Numbers, Real, Sets), Strings (Slicing, Indexing, Concatenation, other operations on Strings), Accepting input from Console, printing statements, Simple ‘Python’ programs.

(iv) Operators, Expressions and Python Statements:-

Assignment statement, expressions, Arithmetic, Relational, Logical, Bitwise operators and their precedence, Conditional statements: if, if-else, if-elif-else; simple programs, Notion of iterative computation and control flow –range function, While Statement, For loop, break statement, Continue Statement, Pass statement, else, assert.

(v) Sequence Data Types:-

Lists, tuples and dictionary, (Slicing, Indexing, Concatenation, other operations on Sequence data type), concept of mutability, Examples to include finding the maximum, minimum, mean; linear search on list/tuple of numbers, and counting the frequency of elements in a list using a dictionary.

(vi) Functions:-

Top-down approach of problem solving, Modular programming and functions, Function parameters, Local variables, the Return statement, DocStrings, global statement, Default argument values, keyword arguments, VarArgs parameters.Library function-input(), eval(),print(), String Functions: count(), find(), rfind(), capitalize(), title(), lower(), upper(), swapcase(), islower(), isupper(), istitle(),replace(), strip(), lstrip(), rstrip(), aplit(), partition(), join(), isspace(), isalpha(), isdigit(), isalnum(), startswith(), endswith(), encode(), decode(), String: Slicing, Membership, Pattern Matching, Numeric Functions: eval(), max(), min(), pow(), round(), int(), random(), ceil(), floor(), sqrt(), Date & Time Functions, Recursion.

(vii) File Processing :-

Concept of Files, File opening in various modes and closing of a file, Reading from a file, Writing onto a file, File functions-open(), close(), read(), readline(),readlines(),write(), writelines(),tell(),seek(), Command Line arguments.

(viii) Scope and Modules:-

Scope of objects and Names, LEGB Rule

Module Basics, Module Files as Namespaces, Import Model, Reloading Modules.

(ix) NumPy Basics:-

Introduction to NumPy ,ndarray, datatypes, array attributes, array creation routines, Array From Existing Data, Array From Numerical Ranges, Indexing & Slicing.

 HOW TO ASSEMBLE PC IN 2021 UNDER  Rs. 20000-25000 Welcome to the Gayan mantra in the “Build Your Own PC” series, In this article, we’re going to be assembling a PC. Before we get down to assembling, we’ll go through all the tools that you’ll typically need for the assembly process and then we can get started. This will be a rather long article as we go through the entire build process step-by-step. Without further ado, let’s start with the tools. First of all follow these Steps: Buy PC Parts    Motherboard under Rs. 3000 to 4000:  1.  Zebronics H61 Motherboard "DDR-3,  I3, I5, I7 Support " 2.  MSI ProSeries AMD A320 1st, 2nd, 3rd Gen Ryzen Compliant AM4 DDR4 HDMI DVI M.2 USB 3 Micro-ATX Motherboard 3.  GIGABYTE AMD A320, AM4 Socket,Ultra Durable Motherboard with Fast Onboard Storage with NVMe,PCIe Gen3 x4 110mm M.2, 4K Ultra HD Support (GA-A320M-S2H) RAM*2 under Rs. 1200 to 1600 for one RAM 1. hynix 4gb ddr3 ram 1600mhz desktop ( for  Zebronics H61 Motherboard ) 2.

Basic of hardware and software.

 Basic of hardware and software. Hardware Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer. Examples of hardware in a computer are the keyboard, the monitor, the mouse and the central processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing (tower). A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer. In contrast to software,  hardware is a physical entity . Hardware and software are interconnected, without software, the hardware of a computer would have no function. However, without the creation of hardware to perform tasks directed by software via the central processing unit, software would be useless. H

  How to increase English reading speed. I have five most effective method to improve your English reading skills. (1) When you read English books you can use a pen line by line and increase speed of pan. Under line the particular word if  you do not know about the word. Use timer and when you reading a book increase your reading skill with a perfect time. (2) You can watching some English moves and speak to dialogue with fluent English. If  you do not have a best pronunciation skill. (3) Use dictionary and pronounce word by word.  So you may be wondering how to improve  English reading  beyond just… reading more books. (4) This is true for reading comprehension too! To really understand what you read, you might need to work on other skills first. You might need to practice reading quickly (or slowly).  (5)You might need to stop choosing very difficult books, and start choosing the  right books for your skill level . Start easier, start smaller and slower, and then gradually increase t
