Answer:
1. Supercomputers
Supercomputers are very expensive and very fast. They are the most powerful computers we have in the world.
Supercomputers are optimized to execute only a small number of programs. This makes it possible for them to execute these few programs at a very high speed. Due to their inhibiting cost, they are used in high-end places like in scientific research centers. The supercomputer consists of thousands of processors, allowing it to clock in at very high speeds measured by petaflops.
These computer types are also very large in size due to the numerous parts and components involved in their design.
A good example of a supercomputer is Tianhe-2, which is located in the National Supercomputer Center in Guangzhou, China. It features 3.12 million cores, allowing it to run at speeds of 33.86 petaflops.
2. Mainframe Computers
These are large and expensive computers that are capable of supporting thousands of users simultaneously. They are mostly used by governments and large organizations for bulk data processing, critical applications, and transaction processing. They are ranked below supercomputers.
3. Minicomputers
Minicomputers are mid-sized computers. In terms of size and power, they are ranked below mainframes. A minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.
The use of the term minicomputer has diminished since the introduction of microprocessors. These machines are now more commonly called midrange computers.
4. Microcomputers
A microcomputer, also known as a personal computer, is designed to be used by one user at a time. The term microcomputer relates to the microprocessor that is used for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive
Answer:
// program in java.
// package
import java.util.*;
// class definition
class Main
{// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// scanner object to read inputs
Scanner scr=new Scanner(System.in);
// variables
String name;
double price;
System.out.print("Enter item's name: ");
// read item's name
name = scr.next();
System.out.print("Enter item's price: ");
// read item's price
price= scr.nextDouble();
// print name
System.out.println("name of item is:"+name);
// print price
System.out.println("price of item is:"+price);
}catch(Exception ex){
return;}
}
}
Explanation:
Read name & price of item from user and assign it to variables "name" & "price" respectively with scanner object.Then print the name and price of item .
Output:
Enter item's name: Apple
Enter item's price: 100
name of item is:Apple
price of item is:100.0
You can separate words in a macro name by using the underscore character.
A macro is considered as a small reusable computer program. It is efficient as it helps you save time by automating any repeated task.
In order to create a macro, you do not need to be an expert in programming, however, a little knowledge about it will help.
