Answer:(1) To manage the computer's resources, which includes central processing unit, memory, disk drives, and printers, (2) To establish a user interface
(3)To execute and provide services for applications software.
The old mainframe computers have
(1) low memory sizes
(2) slower connectivity speed
(3) Larger sizer
(4) low sophistication.
Explanation: Operating system is a system software that manages the computer resources,helps to establish user interface and it helps to provide services for application softwares.
Operating system software includes WINDOWS X,WINDOWS 7,WINDOWS 8,LINUX,etc.
Mainframe computers are computers used by large multinational companies for processing bulk data. Old mainframe computers were produced by IBM(INTERNATIONAL BUSINESS MACHINE) in the year 1952 they are classed two scientific and commercial mainframe computers with different information although they had some incompatibilities. Old mainframe computers are large in size with low processing speed, sophistication and storage compared to present day system.
Going over parts of a computer and how it functions will help you understand all the vital components that make up a computer.
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:
<u>Syntax of function in the Python Programming Language.</u>
def function_name():
'''body of the function or code'''
#calling of the function
function_name()
Note: In Python Programming Language, Indentation is sensitive if you not focus on the indentation then, you program occurs an indentation error.
Explanation:
In Python Programming language, we can use the "def" keyword to define a function then we write the name of the function and then use parentheses for the argument list. "#" is used for the single-line comment and " ''' ''' " is used for the multiple line comment.
A function is the part or module of the program which provides users the feature of reusability of that code anywhere only by calling them.
Answer:
A Tape Library
Explanation:
A tape library, sometimes called a tape silo, tape robot or tape jukebox, is a storage device that contains one or more tape drives, a number of slots to hold tape cartridges, a barcode reader to identify tape cartridges and an automated method for loading tapes. It Enables faster data migrations, reduce the complexity of and increase the frequency of backups, and streamline governance in a secure and cost-effective way.
