Q.1 a. What is an array?
Explain the declaration and initialization of one and two-dimensional arrays
with example.
An
array is defined as an ordered set of similar data items. All the data items of
an array are stored in consecutive memory locations in RAM. The elements of an
array are of same data type and each item can be accessed using the same name.
1D ARRAY
b. A palindrome is a string that reads the same forwards or backwards. For
instance, “madam”, “abba”, and “x” are palindromes, while “ab”, and “foo” are
not. You are to complete a function to determine if a string is a palindrome.
For this question, a string must be exactly the same forward and backward to be
a palindrome, including whitespace (so the string “nurses run” is not a
palindrome here). We will also consider an empty string (length 0) to be a
palindrome.
Write function
IsPalindrome() so it returns 1 (true) if its string argument is a palindrome
and returns 0 (false) if it is not. You may assume that the function argument
is a properly \0-terminated C string. You may use any of the C string library
functions in. You may not copy or modify the string – only examine it.

b. Write a C function
isprime(num) that accepts an integer argument and returns 1 if the argument is
prime, a 0 otherwise. Write a C program that invokes this function to generate
prime numbers between the given ranges.
#include <stdio.h>
int main()
{
int i, num, p = 0;
printf("Please enter a number: \n");
scanf("%d", &
Q. 3 a. What is a
pointer? Explain how the pointer variable declared and initialized.
Pointer is a variable
used to store the address of another variable or a memory location. It always
c. Write
a C program to read n unsorted numbers to an array of size n and pass the
address of this array to a function to sort the numbers in ascending order
using bubble sort technique.

Q.2 What is Operating System? Discuss the different components of
Operating System.
An
operating system (OS) is a platform that controls the implementation of an
application program and acts as an interface between the user and computer
hardware. The purpose of an OS is to provide an environment in which a user can
execute programs in a convenient and efficient manner.

Q. 3 Explain Reference
OSI Model. How is the data transmission done in OSI model?
The layered model that dominated data communications and
networking literature before 1990 was the Open Systems Interconnection (OSI) model.
Everyone believed that the OSI model would become the ultimate standard for
data communications, but this did not happen. The TCP/IP protocol suite became
the dominant commercial architecture because it was used and tested
