Answer:

The class from which a class inherits is called the parent or superclass. A class which inherits from a superclass is called a subclass, also called heir class or child class. Superclasses are sometimes called ancestors as well. There exists a hierarchical relationship between classes. It's similar to relationships or categorizations that we know from real life. Think about vehicles, for example. Bikes, cars, buses and trucks are vehicles. Pick-ups, vans, sports cars, convertibles and estate cars are all cars and by being cars they are vehicles as well. We could implement a vehicle class in Python, which might have methods like accelerate and brake. Cars, Buses and Trucks and Bikes can be implemented as subclasses which will inherit these methods from vehicle.

exis [7]

The available options are:

Emails

Financial spreadsheets

User downloads

Databases

Answer:

User downloads

Explanation:

The correct answer is User downloads, this is because, the downloaded files are in cloud or another website memory or database, which serves as an alternative backup already. Thus, those downloaded files can still be recovered at later time when one needs to get the files back.

However, Emails, Financial spreadsheets and Databases, do not have any other place to retrieve them, because they are originally created and are yet to be uploaded to cloud or another website memory space to serves as alternative back up.

For an external usb hard drive attached to a computer, which is more suitable: a writethrough cache or a block cache

Charra [1.4K]

Disk access is way slower than memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which reduces disk accesses time. Here a portion of disk is bought to cache for reading and a modified blocks are first changed in cache but reflected in the disk at one go. On the other hand with write through caching each modified block is written to cache and at the same time it is written to the disk. Write- through caching requires more disk I/O so they can have a negative effect on the performance.

=((SUM(PUT RANGE OF MOTHLY EXPENSES HERE)*12)+SUM(PUT RANGE OF YEARLY EXPENSES HERE))/12

Explanation:

Adds all of the Monthly Expenses : SUM(PUT RANGE OF MOTHLY EXPENSES HERE)

Multiplies the result by 12: *12

Then adds all of the Yearly Expenses to the product of Steps 1 and 2 : SUM(PUT RANGE OF YEARLY EXPENSES HERE)

Divides this new sum by 12: /12

=((SUM(PUT RANGE OF MOTHLY EXPENSES HERE)*12)+SUM(PUT RANGE OF YEARLY EXPENSES HERE)/12)
