<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!
This is false.
What is cardinality?
Cardinality refers to the entity instances for which it is eligible to participate in a relationship instance. There are two types of cardinality, maximum and minimum.
What is maximum cardinality?
- The maximum cardinality of a relationship is the maximum number of instances of entity B that may be associated with each instance of entity A.
- Maximum cardinality: maximum number of entity instances that can participate in a relationship.
- One-to-One [1:1]
- One-to-Many [1:N]
- Many-to-Many [N:M]

Answer:
The answer is Coarse wavelength division multiplexing (CWDM)
Explanation:
CWDM is the wavelength designed for short- distance connections and has only a few lambdas. It is mostly used nowadays as a type of wavelength technologies deployed in cities and inner access ways. It is inexpensive and thus a cost effective wavelength division multiplexing. Cost effective lasers can be used in CWDM due to the spacing of about 20nm between its wavelengths.
Answer:
This is known as the Metcalfe's Law
Explanation:
In 1980, Metcalfe's law was first presented, not considering users but the communication among compatible devices (e.g. telephone, fax machines and so on). It was after the globalization of the internet that the law got introduced to users and networks.
A demonstration of the law can be seen in fax machines, one fax machine is purposeless, however, the interconnection of multiple fax machines on the network increases the value of every fax machine because the number of the users of the fax machines increases. Similarly, the more the users of a particular service, the more relevant the service becomes.
Answer:
Option D is the correct choice answer for the above question.
Explanation:
"exit()" is a function that is used to transfer the control of the program to the end of the program and the program gets terminated. This function defines in many programming languages. The syntax of this function is as follows--
exit() // syntax of the exit function.
Hence anybody can say that "exit" function is used to terminate the program if there are many lines belongs after the "exit()" function. Hence option D is the correct answer while other is not because--
- Option A states about the "terminate()" function which is not the function of any programming language.
- Option B states about the "return()" function which is also not the function of any programming language but "return" is a statement used to return the value.
- Option C states about the "continue()" function which is used in a loop to escape the other line of the loop and continue it.
