<h2>Hello!</h2>
The answer is:
- CD
- DVD
- UDO
<h2>Why?</h2>
Optical disks are circular disks used as storage for binary data usually made of polycarbonate. The data is stored in the disc using a laser machine and accessed using a laser diode illuminating the data path in an optical disc drive.
CD: Compact Discs are the most basic optical disk used today, with only a capacity that goes from 0.7 GB (700 MB) to 0.84 GB (840 MB).
DVD: Digital Versatile Discs increase the storage up to 6 times compared with a CD, the capacity of DVDs optical disks goes from 4.7 GB (4700 MB) to about 17 GB(17000 MB).
UDO: Ultra Density Optical have high capacity storage that goes from 30 GB (30000 MB) to about 60 GB (6000 MB).
Have a nice day!
The correct answer is C. Typeover mode
This is when you select a
text and can then type over it and it automatically replaces it with
what you're writing. It also creates a little box that lets you edit the
selected part easily if that's what you need with things like bold or
italic or change the text color.
Answer:
The program to this question as follows:
Program:
def lettersOnly(s): #defining method lettersOnly
val="" #defining string variable that return value
for i in s: #defining loop to calculate value
if(i.isalpha()): #check condition that value is string
val=val+ i #add value
return val #return value
print(lettersOnly("data3base_ro1c3k5s")) #call method and print value
Output:
databaserocks
Explanation:
In the above python code, a method lettersOnly is declared that accepts a string variable "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.
- In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.
- At the last, the print method is used, which calls the lettersOnly method and prints its return value.
Answer:
Electromagnetic interference and noise from the transmitting or receiving device.
Explanation:
Communication involves four processes, they are; encoding, sending, decoding, and feedback. A message, during this process of communication, can be altered, this is known as noise.
Telecommunication is simply communication between long distances. The effect of noise is more pronounced and can be noticed by listeners. These noises are produced by the transmitter and electromagnetic signals or waves of other transmitting devices.
