The two access modes that are used when opening a file for input and output when pickling are rb and wb.
<h3>What is pickling?</h3>
Pickle is generally used in Python to serialize and deserialize a Python object structure. In other words, it is the act of transforming a Python object into a byte stream in order to save it to a file/database, maintain program state across sessions, or transport data over a network. By unpickling the pickled byte stream, the original object hierarchy can be recreated. This entire procedure is comparable to object serialization in Java or .Net.
When a byte stream is unpickled, the pickle module first makes an instance of the original object before populating it with the right data. To accomplish this, the byte stream only carries data relevant to the original object instance.

Operating system basically allow various task to run simultaneously by the user. In an operating system, each task consume storage system and all the other resources.
Multitasking function facilitate memory isolation in the processor and also supported different levels of security system in the operating system. For example, "a programmer working on any program in a system and as well as listening the music then, it perform multiple task at the same time".

The answer is Laser Printer. It is a non impact printer that creates characters and images with dots by using a drum and toner. The main advantages of laser printers are speed, precision and economy. A laser can move very quickly, and because the laser beam has an unvarying diameter, it can draw more precisely, without spilling any excess ink.
They need to be close to a body of water and being in a valley is good because they are protected because they have mountains around
