Answer:
// program in C++.
// headers
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// Variable
int num;
cout << "Enter a number between 1 and 10: ";
// read input
cin >> num;
// validate input number
while(num<1||num>10)
{
// if input is wrong then print error message
cout<<"Wrong input!!Enter again:";
// read again
cin>>num;
}
// print output
cout << "The Roman numeral for "<<num<<" is:";
// switch
switch (num)
{
case 1:
// if input is 1
cout<<"I"<<endl;
// exit the switch
break;
case 2:
// if input is 2
cout<<"II"<<endl;
// exit the switch
break;
case 3:
// if input is 3
cout<<"III"<<endl;
// exit the switch
break;
case 4:
// if input is 4
cout<<"IV"<<endl;
// exit the switch
break;
case 5:
// if input is 5
cout<<"V"<<endl;
// exit the switch
break;
case 6:
// if input is 6
cout<<"VI"<<endl;
// exit the switch
break;
case 7:
// if input is 7
cout<<"VII"<<endl;
// exit the switch
break;
case 8:
// if input is 8
cout<<"VIII"<<endl;
// exit the switch
break;
case 9:
// if input is 9
cout<<"IX"<<endl;
// exit the switch
break;
case 10:
// if input is 10
cout<<"X"<<endl;
// exit the switch

Explanation:
Read a number from usr and assign it to variable "num". If the input number is less than 1 or greater than 10 then ask again to enter a number until user enter a number between 1-10 only.Then with the help of switch() function print the equivalent Roman number.
Output:
Enter a number between 1 and 10: -5
Wrong input!!Enter again:12
Wrong input!!Enter again:6
The Roman numeral for 6 is:VI
Answer:
Direct data access reduces the speed of retrieving data from memory or storage. Retrieving data and storing it in a cache memory provides direct access to data in the storage.
Explanation:
Sequential memory access, as the name implies, goes through the memory length location in search of the specified data. Direct memory access, provides a memory location index for direct retrieval of data.
Examples of direct and sequential memory access are RAM and tapes respectively. Data in sequential memory access can be access directly by getting data in advance and storing them in cache memory for direct access by the processor.
