The given statement is false because the five major components of a computer system are hardware, software, data, procedures and telecommunications. Code is not a component of a computer system. It is a set of instructions given to a computer to perform different actions.
Computer information systems or simply computer systems are systems which are composed of people, computers and intercommunications among them. These systems are used to collect, store, and process data, primarily within an organizational setting.
A brief description of each component of computer systems is given below:
- Hardware: It represents all the physical elements of computer systems that work with information.
- Software: This component includes all sets of instructions required to process data and information.
- Data: All data that the other components work with resides on this component.
- Procedures: They include all the procedures that human resource use in order to retrieve useful information from the bulk of data.
- Telecommunication: The component telecommunications consists of communication media and networks. This component joins the hardware devices together to establish telecommunication connections. Connections can be wireless or through wires.

Answer:
20 20 vision, is how it relates to the eye.
Explanation:
(If you work with a computer for more than seven hours each day, take a 20-second break right now, look at an object that is 20 feet away, and start reading. The 20-20-20 rule is defined as a 20-second break to look at something 20-feet away every 20-minutes.) This will help prevent eye strain, blurriness and dry eyes etc.

The Format Painter option.
When you want to apply cell formatting to a cell or a range of cells, it is much easier to use the format painter. This tool is found on you toolbars with a picture of a paintbrush. To use the format painter, select the first cell or range of cells, click the Format Painter on the Home tab and paste the conditional formatting by dragging the paintbrush across the cell or range of cells you want to format.
Answer:
The program to this question can be given as:
Program:
#include <stdio.h> //include header files
#include<math.h>
int main() //main method
{
double treeHeight = 0.0; //declare variables
and assign value
double shadowLength = 0.0;
double angleElevation = 0.11693706;
// (0.11693706 radians = 6.7 degrees) convert number into angle.
shadowLength = 17.5;
treeHeight = shadowLength * tan(angleElevation); //convert number into angle
printf("Tree height: %lf\n", treeHeight); //print value.
return 0;
}
Output:
Tree height: 2.055778
Explanation:
In the above C language program firstly we include the headers. In this header file, we include a (math.h) header file this file helps to use the math function. Then we declare the main method in the main method we declare the variable that is given in the question that are treeHeight, shadowLength , angleElevation. All the variable datatype is double because it stores the floating-point value. Then we apply the formula that is treeHeight = shadowLength * tan(angleElevation). In this formula, the treeHeight variable holds the value. Then we print the variable value for print the double value we use the lf(that is long float).
