The answer to this question is B.
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.
Answer:
a. x = 5
b. x = 7
Explanation:
a)
OUTPUT: x = 5
In the main() function, fun1() is evaluated first and it updates the value of the global variable to 2 and returns 3.
The second function returns the value of the global variable 'a' and this variable has value 2.
So,
x = 3 + 2
x = 5
b)
OUTPUT: x = 7
In the main() function, fun2() is evaluated first and it returns 4 because global variable 'a' is initialized with value 4.
The second function fun()1 will returns the value 3.
So,
x = 4 + 3
x = 7
Answer:
RGB
Explanation:
R=red
G=Green
B=Blue
RGB is standard scheme of colors ,rest of the colors use to be make by mixing three of these colors. These are standard colors use for monitor,computer and Tv screen.
RBG plays an vital role in the memory of the computer. For example the JPG file is RBG-24 bit file. So it is easy to upload the file that is JPG and it is easy to edit and upload. This file is taking less RAM so the editors usually keeps the JPG file along with them because it is easy to compress and edit the file.
Hence it is proved that RGB color coding is very efficient for the usage of the memory because it is already a compressed file and use the RAM so efficiently, so the quality of task done by CPU would never be compromised by using RGB.
Large photo is usually composed of more colors and the computer use to struggle alot for such iamge files.
The RGB code (0-255 for each of R, G, B) carrirs 16777216 possible matches. It's not almost "every new color," but it made up more than most of the colors humans can easily identifies.
we must say that RGB is not the perfect choice for making every possible color that is existing but it is quite helpful in making every unique color that a human could identify. RGB is mostly makes the light color with the combination of these three colors.
RGB is not the best for making every possible color but it is so useful as far as the computer memory is concern it uses very less memory and it file is quite light. Uploading of JPG file is easy ,it takes less time and memory.
On clouds the memory is most important element so, mostly the RGB are preferred colors and these are enough to represent in compute scheme.
The answer is #’s 1 and 4 are True.
