Answer:

Serial SCSI

Explanation:

Hot swapping can be defined as a process which typically involves fitting or replacing CD-ROM drive, hard-disk drive, power supply or other peripheral devices while a computer system is powered on. Thus, it allows for the installation or removal of a peripheral device from a computer while power is still being supplied to the computer i.e without having to shutdown the computer.

Serial SCSI is a SCSI standard which allows for the technique known as “hot swapping” because it's a point to point connection that is designed to move data to and from computer storage serially.

Java Eclipse homework. I need help coding this

olganol [36]

Answer:

I can't just do your project but use this as a head start.

Explanation:

public class TableOfBases

{

public static void main(String[] args)

{

// print out "Decimal Binary Octal Hex Character";

// write a for loop from 65 to 90

for (int i ... ) {

// get a string for integer i with base 2

String binary = Integer.toString (i,2);

// get a string for integer i with base 8

String octal = Integer.toString( ... );

// get a string for integer i with base 16

String hex = ...

// get a char for a chararater that has ASCII code i

char ch = (char) i ;

// print out binary, octal and hex, and ch

}

Project... Basically Speaking

Create a project called TableOfBases with class Tester.

The main method should have a for loop that cycles through the integer values

65 <= j <= 90 (These are the ASCII codes for characters A â€“ Z).

Use the methods learned in this lesson to produce a line of this table on each pass

through the loop. Display the equivalent of the decimal number in the various bases

just learned (binary, octal, and hex) as well as the character itself:

Decimal Binary Octal Hex Character
