Answer: a)Physical access
Explanation: Physical access is the function that permits the accessing of the computer system in a physical way. This access work on the building, It organization and other physical buildings.This access make the system prone to high amount of corruption and hacking .
Other options are incorrect because technical access is for the accessing the technical parts,operational access is for controlling the functions and remote access is for accessing the system from remote area.Thus the correct option is option (a).
Answer:
Input example:
select the funcion: 1
write the 1sd number2
write the 2nd number1
value is 2.000000
Explanation:
#include <stdio.h>
main()
{
//define the variables as float
float a, b, c, e;
char d;
while (1)
{
//input values
printf("select the function: ");
scanf("%c",&d);
printf("write the 1sd number");
scanf("%f",&a);
getchar();
printf("write the 2nd number");
scanf("%f",&b);
getchar();
if (d=='%')
{
a=a*b/100;
}
if (d=='*')
{
a=a*b;
}
if (d=='+')
{
a=a+b;
}
if (d=='/')
{
a=a/b;
}
if (d=='-')
{
a=a-b;
}
printf("value is %f \n",a);
}
printf("final value is %f",a);
getchar();
}
Answer:
The gates required to build a half adder are :
- AND Gate for Carry.
- XOR Gate for Sum
Explanation:
AND Gate is required for the carry and the XOR gate is required for the sum.
The figures for the gates and the truth tables for the half adder are attached so please refer them for further explanation.
The sum is 1 when one of the input is High or 1 if both the inputs are same then the sum is 0.So this behavior is implemented by X-OR gate.
The carry is High only when both of the inputs are 1.This is implemented by AND-Gate.
When green, the signal means D. all of the above.
A green traffic signal means that you have the right-of-way, but you must yield to pedestrians and vehicles already in the intersection. If you hesitate or slow down, you may cause an accident or hold up traffic behind you, so it is important that you move swiftly and carefully to avoid causing any problems.
