Unit 2: Basic Python Operations and Control Flow
1. Check if a Number is Even or Odd
n = int(input("Enter a number: "))
print("Even" if n % 2 == 0 else "Odd")2. Determine if a Number is Positive, Negative, or Zero
n = float(input("Enter a number: "))
if n > 0:
print("Positive")
elif n < 0:
print("Negative")
else:
print("Zero")3. Generate Fibonacci Series of Length ‘n’
n = int(input("Enter the length: "))
a, b = 0, 1
for _ in range(n):
print(a, end=" ")
a, b = b, a + b4. Generate

Definition of a Business Process
A sequence of activities that a company performs to achieve a specific goal. These activities can be automated or manual, and they are organized in a specific order to ensure efficiency.
Example: Order fulfillment process.Business Process Management (BPM)

Essential Recursive Algorithms and Backtracking Techniques
1) Factorial of n
Question
Compute n!.
Explain question
Return the product 1 * 2 * ... * n. The problem is naturally defined in terms of a smaller n.
Approach (in-depth)
If n is 0 (or 1) the answer is 1. Otherwise the factorial of n = n * factorial(n-1). The recursion reduces n by 1 on every call until the base case. No branching — just a single recursive call. This is linear recursion.
Recurrence relation
fact(n) = n * fact(n-1), with fact(0)=1.
Pseudocode
function fact(n):
if n == 0: return 1return Understanding Computer Bus Architecture and Performance
Introduction to the Concept of the Computer Bus
Computers require a large amount of information to be managed and processed. To facilitate the flow of this data between various components, specific paths are needed. These “paths” are called buses. They are internal circuitry of the motherboard that allows the sending of data between components. The bus largely defines the speed of the computer itself, because the faster the data is sent, the more operations can be performed per second.
A bus, in computing,

Linux Memory Management Components
There are two primary components to memory management under Linux:
- The physical memory management system, which deals with allocating and freeing pages, groups of pages, and small blocks of memory.
- The virtual memory system, which handles memory mapped into the address space of running processes.
Physical Memory Management
The primary physical memory manager in the Linux kernel is the page allocator. This allocator is responsible for allocating and freeing all physical

Memory Management Fundamentals
Memory management is a function of an operating system (OS) that handles the allocation and deallocation of memory to programs and processes.
Single User Operating Systems (OS)
In a Single User OS, only one user can use the system at a time. Consequently, memory is managed in a simple way.
Key Features of Single User OS Memory
- Single Program in Memory: Only one program is loaded in memory at a time. No multitasking is supported.
- Contiguous Memory Allocation: The program
