Communication Structures
Key Elements:
- Naming and Name Resolution: Identifies processes with host and process IDs, utilizing DNS.
- Routing Strategies:
- Fixed Routing: Predefined path from source to destination.
- Virtual Circuit: Fixed path for a single session.
- Dynamic Routing: Path determined at the time of message sending.
- Connection Strategies:
- Circuit Switching: Dedicated physical link for the duration of communication (e.g., mobile phones).
- Message Switching: Temporary link for a single message transfer
Data Structures and Algorithms
Time Complexity
Determining the time complexity of an algorithm involves analyzing the number of loop executions. The growth function represents the exact relationship between the problem size (n) and the time complexity of the solution. The order of an algorithm refers to its asymptotic time complexity as the problem size and algorithm complexity approach their asymptotic limits.
Common time complexities include:
- O(1) – Constant time
- O(log n) – Logarithmic time
- O(n) – Linear time
- O(n log n) – Log-linear

Searching Algorithms
Linear Search
The linear search algorithm sequentially checks each element in a list until it finds the target value. It’s simple but inefficient for large lists.
C Code for Linear Search
#include #include void main(){ int a[50],i,n,elt,count; clrscr(); printf("\n\tLINEAR SEARCH"); printf("\n\t \n\n"); printf("\n\tEnter the limit:"); scanf("%d",&n); printf("\n\tEnter the elements:"); for(i=0;i
