Answer:
Output explanation to the given code can be defined as follows:
Explanation:
In A the output is 0
, It will return fork value of the child process that is 0. so, 0 is printed during child process.
In B the output is 2650
, in which the getpid() method returns the child process id value that is 2650.
In C the output is 140, As it is declared in key, all process have their own "value" copies. 20 are inserted during childhood, so 140 are written.
In D the output is 2650, its fork() method returns the child ID to the parent process. so the value 2650 is printed.
In E the output is 2600, Its getpid() method will returns parent process id that is equal to 2600.
In F the output is 120 Since the value is declared in primary, all process so their own "value" copies. 120 will be printed during process.
Answer:
Central Processing Unit
Explanation:
When the CPU puts the address of a peripheral onto the address bus, the input–output interface decodes the address and identifies the unique computer peripheral with which a data transfer operation is to be executed.
<u><em>Differences between barcode reader and character recognition devices:</em></u>
Barcode Reader or Barcode Scanner:
- Barcode Scanner scans the data by brightening the barcodes usingSensor
- The analog signal is then converted into digital signal by Converter.
- The Decoder calculates the converted data and sends valid data to the computer.
Character Recognition Devices (OCR):
- OCR scans the physical document and converts them into two-coloured format.
- The darker and lighter area are identified as characters and blanks respectively.
- The common methods used are: Pattern Recognition and Feature Detection.
Answer:
Explanation:
The following is written in Java and creates the Employee class with the variables requested and a getter setter method for each variable
package sample;
public class Employee {
private String lastName, firstName, idNumber;
public void Employee() {
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getIdNumber() {
return idNumber;
}
public void setIdNumber(String idNumber) {
this.idNumber = idNumber;
}
}
