<u>The first tools that analyzed and extracted data from floppy disks and hard disks were MS-DOS tools for </u><u>IBM</u><u> PC file systems</u>. A file system is a structured representation of data and a set of metadata describing this data. The file system of the IBM supports stream input/output and storage management, providing a structure over all information stored in the system. A floppy disk consists of a thin plastic disk coated with magnetic material (it was designed by IBM in the early 1970s). A hard disk is fixed on the system unit. It is made up of several circular disks called platters. MS-DOS (Microsoft Disk Operating System) is a licensed operating system for use on microcomputers from various manufacturers.
Answer:
Following are the program definition in the Java Programming Language.
//define a class
public class Clock
{
//set integer type variable and initialize value
private int hours=12;
//set boolean type variable and initialize value
private boolean isTicking=true;
//set integer type variable and initialize value
private Integer diff=5;
}
Explanation:
Following are the description of Code.
- Firstly define a class "Clock" with the "private" access modifier.
- Then, set the integer data type variable "hours" with the "private" access modifier and assign value 12 in that class.
- After that, set the boolean data type variable "isTicking" with the "private" access modifier and assign value "true".
- Finally set Integer class variable "diff" with the the private access modifier and assign value 5.
Answer:
The definition of function is as follows:
def typing_speed(number_of_words,Time_Interval):
number_of_words>=0
Time_Interval>0
speed=float(60*number_of_words/Time_Interval)
return speed
Explanation:
Above function is defined step-by-step as follows:
def typing_speed(number_of_words,Time_Interval):
- A function named typing speed has two arguments, num_of_words and Time_Interval.
number_of_words>=0
Time_Interval>0
- The variable number_of_words is the number of words entered that a person enters, they must be greater than or equal to 0. Where as Time_Interval is the variable for counting the time span in seconds, it must be greater than 0.
speed=float(60*number_of_words/Time_Interval)
return speed
- For determining result firstly the seconds are converted int minutes by multiplying with 60 and number_of_words is divided with Time_Interval in order to get words per minute. The return value will give speed which has data type float.
