JNTU B.Tech I COMPUTER PROGRAMMING IN C Previous Question Paper (June - 2022 - R16)

Computing environments represent the various settings in which software and hardware interact to perform tasks. The primary categories are:

1. Personal Computing: Designed for individual use, such as desktops, laptops, and tablets. These systems provide a dedicated interface for a single user to run local applications.
2. Client-Server Computing: A distributed architecture where a client machine requests services or resources from a central server. The server manages data, security, and resource allocation, while the client handles user interaction.
3. Distributed Computing: A system where components are spread across multiple networked computers. These systems communicate and coordinate actions to achieve a common goal, providing scalability and fault tolerance.
4. Cloud Computing: An on-demand delivery of computing services (servers, storage, databases) over the internet. It offers flexibility and cost-efficiency through virtualization and shared resources.
5. Embedded Computing: Systems integrated into larger mechanical or electrical devices (e.g., microcontrollers in washing machines or automotive systems) to perform specific, dedicated functions.

A perfect number is a positive integer that is equal to the sum of its proper positive divisors, excluding the number itself. The flow chart logic is as follows:

1. Start.
2. Input a number, n.
3. Initialize sum = 0 and i = 1.
4. Check if i < n. If true, proceed to step 5; else, go to step 8.
5. Check if n % i == 0. If true, set sum = sum + i.
6. Increment i = i + 1.
7. Go back to step 4.
8. Compare sum == n. If true, print 'Perfect Number'; else, print 'Not a Perfect Number'.
9. Stop.
