Answer:
The answer to this question is given below in this explanation section.
Explanation:
"difference between cd-r, cd-rw and cd-rom"
CDs are also known as WORM discs,for "write once Read many".A re writable version based on excitable crystals and known as CD-RW was introduced in the mid 1990s because both CD-R and CD-RW recorders originally required a computer to operate they had limited acceptance of use as computer software.
A compact Disc Read only memory (CD-ROM) is a read only disc.A compact disc Re-writable (CD-RW) is an erasable disc that can be reused.The data on a CD-RW disc can be erased and recorded over numerous times.CD-RW may not be readable outside of the drive it was created in.
cd-r :
CD-R is a digital optical disc storage format.A CD-R disc is compact disc that can be written once and read arbitrarily many times.
CD-R stand for" compact disc" Record-able .CD-R disc are blank CDs that can record data written by a CD burner.The word "record-able" is used because CD-R are often used to record audio,Which can be play back by most CD players.
cd-rw:
CD-RW compact disc re-writable is a digital optical disc,storage format introduced in 1997.A CD-RW compact disc can be written read erased and re-written.
in this case of CD-RW the writing laser makes permanent marks in a layers of dye polymer in the disc.CD rewrite-able discs in a similar fashion,except that the change to the recording surface is revers able.
cd-rom:
CD-Rom observation of compact disc read only memory type of computer memory in the form of compact disc that is read by optical means.A CD-ROM drive uses a low power laser been encoded in the form of tiny pits on a optical disk.The "ROM" part of the term means the data on the disc "read only memory" or cannot be altered or erased.
What kind of question is this?
Answer:
Computer engineering is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software.
Explanation:
Answer:g
public static int addOddMinusEven(int start, int end){
int odd =0;
int even = 0;
for(int i =start; i<end; i++){
if(i%2==0){
even = even+i;
}
else{
odd = odd+i;
}
}
return odd-even;
}
}
Explanation:
Using Java programming language:
- The method addOddMinusEven() is created to accept two parameters of ints start and end
- Using a for loop statement we iterate from start to end but not including end
- Using a modulos operator we check for even and odds
- The method then returns odd-even
- See below a complete method with a call to the method addOddMinusEven()
public class num13 {
public static void main(String[] args) {
int start = 2;
int stop = 10;
System.out.println(addOddMinusEven(start,stop));
}
public static int addOddMinusEven(int start, int end){
int odd =0;
int even = 0;
for(int i =start; i<end; i++){
if(i%2==0){
even = even+i;
}
else{
odd = odd+i;
}
}
return odd-even;
}
}
