Triss [41]3 years ago

Answer:

Object-oriented programming (OOP) is a procedural language and based on classes associated with an object. Without classes and object relationship OOP is not possible. According to program's design concept classes provide abstraction and encapsulation with the help of object. Object have states and behaviors like cat has states like name, color and  cat has also behaviors like  wagging the tail, eating, jumping etc. A class forms template or blueprints for these states and behaviors because different cats have different behaviors and states.

Methods provide a way for encapsulation and accessing private class members with public methods and static fields are sometimes best alternative for global variable. We can use static field when it same for all and shared by all objects of that class and it can save memory because we do not have to initialize it for each object

At the beginning of Section 5.2, it is stated that multiprogramming and multiprocessing present the same problems, with respect
QveST [7]

Answer:

By definition, <u>multiprocessing</u> refers to the processing of multiple processes at the same time by multiple CPUs.

By definition, <u>multiprogramming</u> keeps programs in main memory at the same time and execute them concurrently utilizing a single CPU doing a context switch.

The first difference is that multiprocessing uses multiple CPUs and multiprogramming to utilize context switch to do concurrency in one CPU. Another difference is that multiprocessing is more expensive but more efficient than multiprogramming due that it allows parallel processing.

To what would you compare the transport layer?
Nikolay [14]
The above question has multiple choices as below

A. Data links
B. The post office
C. Driving a car
D. A train

The answer is (B) The Post Office.

In layman’s terms, transport layer is similar to the post office functions of delivering parcels and letters at the agreed delivery deadlines. It also notices any dropped info and re-transmits it.
Just like the post office, the transport layer directs messages and information between specific end users. If by mistake you write a letter to the wrong person, the letter will be returned and the postal employee will stamp it as address unknown.
