Example text

A process is an instance of an executing program. Each process has its own virtual address space and a thread of control. Thread is the basic unit for which Scheduler (operating system) allocates processor time. We can think of a system as a collection of processes running in a quasi-parallel environment. Rapid switching between processes (programs), back and forth, is called multitasking. Processes and threads In the following figure, we see a single core CPU multitasking system with four programs scheduled for execution: In the following figure, we have a multicore CPU multitasking system with four executing processes, each one with its own control flow and each one running independently of the other ones: In the following figure, we see that over a time interval, processes have made progress, but at any instant of time, only one process can run on one CPU core: 46 Chapter 2 As we said earlier, in any traditional operating system, each process has an address space and a single thread of control.

This is why it is called dynamic binding. Event handlers and Message Passing Interface Many programs respond to some events, such as when a user presses a button or inputs some text. A very important mechanism is event handling or the ability of a program to react to user action. If we want to handle when a user presses a button, we need to create some kind of a listener that will listen to button events, in this case a press action. 28 Chapter 1 An event handler is a function that the operating system calls each time the control sends some kind of message, such as I have been pressed in the case of buttons or I received a character in the case of a textbox.

Overriding a method is a feature that allows a derived class to provide a specific implementation of a method that is already provided in the base class. Take a look at the WhoAmI method from the previous example. Its output will be as follows: I am a person I am a worker I am a student Even though a method from each class has the same name, it is a different method and has a different functionality. We can say that the WhoAmI method is overridden in the CPerson derived class. There's more... Overriding is an excellent feature in OOP and C++, but polymorphism is even better.
